It was an ordinary day at the Golden Oak Library. Deadpool was downstairs in the living room as always. He was reading "Deadpool & Cable: Split Second #1".

"Hey, Wade?" Said Twilight from upstairs.

"Yes, dear?" Replied Deadpool.

"Could you do me a favor and go to the market and get some groceries? I would go get them myself, but Princess Celestia sent me some materials to look over for my studies as Princess that I would like to look over."

"I'd be happy too. I'm just looking over an old comic series I was a part of."

"Great! I left a list for you by the door."

Deadpool set his comic book down, ran upstairs, grabbed the grocery list, and walked out the door.

(I find myself curious. Why were you looking over an old storyline featuring you and Cable?)

"Because it's been a while since I last saw him, and I kinda miss my ole' buddy. It's too bad that cellphones haven't been invented yet, otherwise I would've given him a call ages ago," Said Deadpool to himself.

(Would we even be able to call him when he's in the future?)

(Do you ever miss the rest of our pals? Like Domino, Colossus, or all of the other X-Ponies?)

"First off, Domino and I haven't really seen each other after what happened between us a couple years ago. Second, Colossus and I have been writing to each other and coming up with stuff we can do every week. And lastly, I'm pretty sure I am still not on good terms with the rest of the X-Chumps after the incident."

(Yeah, well, we got new better friends who don't get upset with us when we crash shit on their front lawns!)

After a few minutes, Deadpool arrived at the Ponyville Marketplace. He walked over to a fruit stand, and was inspecting the various fruits for sale. While looking at a couple eggplants, he felt someone tap his shoulder.

"Can I help… you?"

Standing behind him was an earth pony stallion. He had a tan coat, and a short brown mane and tail. Deadpool noticed that the stallion's eyes were glowing red. Before he could react, he was struck by an optic blast. He was launched into the fruit stand, breaking it in half.

"O-Oh… That hurt. Did any of you notice he has Summers' optic blasts?

(I did. But unlike Scott, he seems to be able to control his optic blasts without wearing ruby-quartz glasses or visor.)

(He even looks like him! Is he a clone?)

"Only one way to find out. Hey, are you or are you not a clone created by an organization such as InGen?"

Deadpool's question was completely ignored. The stallion charged up another optic blast and fired. Deadpool dodged out of the way, while innocent civilians in the immediate area ran away in panic. Deadpool pulled out his pistols and fired several rounds of energy bullets. The stallion managed to use a market stand as cover, and fired another optic blast. The blast grazed against Deadpool's side. In retaliation, Deadpool fired more energy bullets while running towards his adversary.

The stallion dodged out of the way, but Deadpool ran up to him and smacked him in the face with one of his pistols. He then put both of them away, and switched them for his katanas. He swung both of his swords at the stallion, but he dodged them by moving to the left. Deadpool swung a couple more times, managing to scratch the stallion's left foreleg. With blind rage, the stallion charged up another optic blast.

(Move, move!)

Deadpool was unable to move out of the way in time. The optic blast decapitated his head from his body. Before his head could hit the ground, the stallion caught it.

"Uh, would you be opposed if we call it good?" Asked Deadpool nervously.

The stallion's eyes glowed red yet again. He concentrated his optic blast to the center of Deadpool's skull. The hero could feel his brain melting inside of him.

"Gahhhhhhhhhhh!"

SHULK!

"Gugh!"

The stallion was stabbed from behind, causing him to drop Deadpool's head on the ground. Before the hero lost consciousness, he saw what appeared to be a sword made of purple energy sticking out of his adversary's chest.

A few minutes later, Deadpool regained consciousness. He reached out for his head, feeling around his neck. Just this action confirmed that his head was reattached to his body. He then looked forward, and saw something unexpected. He saw two mares standing in front of him, but he only saw their rear ends.

"Holy haunches! Am I awake or unconscious?!" Asked Deadpool to himself.

(Only one way to find out!)

Deadpool reached for the mares' butts in front of him with both of his hooves.

(I'm pretty sure this is illegal. Plus not to mention you are in a relationship.)

"I'll make it quick. They won't even notice."

Just as he was about to grab their rears, he heard -

"Good, you're finally conscious, Wade,"

Deadpool frantically put his hooves against his side when he heard one of the mares addressing him. They both turned around, revealing much more of their features. A mare standing to his left was a unicorn with a chalk white coat and long black mane and tail. She wore a tight-fitting black bodysuit that had some padding and armor built into it, and turquoise harness straps along the sides and linked into a belt. On her flank where her cutie mark would be was a domino with the number seven. Probably her most striking feature was a black circle tattoo around the left eye.

Standing to Deadpool's right, the other mare was an earth pony. She was pink lavender in color with a long purple mane and tail. She wore a sleek leotard that collared at the neck with bands around her forelegs and thighs, and wore long gloves and high boots. The leotard was tied together with a red flowing sash around her waist. On her partly exposed flank was a butterfly made of pink energy for her cutie mark.

"Domino?! Psylocke?! I thought I recognized those curves, especially yours, Domino," Said Deadpool.

"Do you really think it is appropriate to be talking about my ass?" Asked Domino rhetorically.

"We're friends, Domino. Friends compliment each other all the time. In our case, I compliment your ass, while you compliment my mental stability. What are you two doing here anyway?"

"We came for him." Psylocke tossed the body of the stallion that attacked Deadpool in front of him. "He's a clone of Scott Summers. More clones of him and other mutants have been appearing across Equestria. The X-Ponies have been spread out across the country fighting clones."

"Looks like I was right about him being a clone. Do you have an idea of who created them?"

"We have our suspicions, but we were supposed to meet up with an acquaintance here for confirmation," Said Domino.

"An acquaintance? Are they anyone I would know?"

VWOOM!

"Holy shit!" Cried Deadpool.

Suddenly, a beam of blue light came down from the sky in front of the three ponies. When the light faded away, an earth pony stallion stood in a small, smoking crater. He had a tall stature with a muscular build. His coat was tan in color with a short white mane and tail. He wore a blue tunic with a yellow shoulder pad on his right shoulder, blue pants with a symbol of a red X where his cutie mark would be, and an ammunition belt strapped around his torso. His left eye, foreleg, and shoulder were bionic.

"(Gasp) Oh my god! It's Cable!" Said Deadpool excitedly.

(Aw yeah! It's fuckin' Cable!)

(The stallion out of time!)

(And he likes to fight crime!)

"Will you two please shut the fuck up and stop singing?! I don't want to get sued by High Moon Studios for copyright infringement!" Said Deadpool to himself.

Deadpool ran up to Cable and hugged him tightly, much to the confusion of the latter.

"It's so good to see you, Cable! I was just talking about wanting to see you again! It's almost like we were destined to meet up again!"

After a few seconds, Cable pried Deadpool off of him.

"Good to see you too, Wade," Said Cable.

"Okay, Summers, what's going on?" Asked Psylocke.

"I will cut to the chase: An old adversary of ours has resurfaced - Mister Sinister," Answered Cable.

"Mister Sissy-ter has returned?! Questioned Deadpool in disbelief.

(With a name like "Mister Sinister" you would just be disappointed if he wasn't a super villain.)

"He's made a clone army out of DNA samples he had collected from various mutants, including the X-Ponies. He has already deployed some of his troops across Equestria and the world, and he plans on deploying the rest of his army in six hours. If he succeeds, then he will be able to carry out his goal of instilling 'genetic perfection' onto this world," Said Cable.

"This sounds vaguely familiar. Was I part of a project with a similar plot?" Asked Deadpool to himself.

"We're going to need all of the help we can get. Do we have anyone else tagging along?" Asked Cable.

"The X-Ponies are preoccupied with dealing with Sinister's clones. Even our allies across the world have their hooves full with them," Said Domino.

"Looks like it's just going to be us then," Said Cable.

"The four of us together? Like two years ago? … Yes! X-Force is back together again! Guess who's back, back again?! X-Force's back, tell the comic fans!" Chanted Deadpool excitedly.

All of Deadpool's friends groaned at him.

"No, Wade, we are not reforming X-Force," Said Domino exasperatedly.

"Why not?! The world is in danger, and we are all together again. This is the perfect moment to reform X-Force!" Said Deadpool while crossing his arms into the shape of an X.

"We're only going to be together until we beat Mister Sinister, then we will be going our separate ways. Just as we did two years ago when we disbanded X-Force," Said Cable.

"And X-Force only lasted for a year anyway," Added Psylocke.

"Ugh, fine! If you all are going to be such bummers about it, then we are just friends banded together in order to save the world. So, which door do we have to FBI open up raid on to find Mister Sinister?" Asked Deadpool.

"We have to go to Genosha," Answered Cable.

"Whoa, whoa, whoa! Hold up a second! You're telling me that Count Dracula is on THE Genosha? As in the island? The site of one of the worst mutant massacres in history? … Awesome! Take us there through time and space, Drill Sergeant!"

"If I could, Wade, I would. Unfortunately, the Temporal Dial I normally use is being repaired, so I have to use an old prototype. This one only has two charges. One to get me here, and another to return me to my timeline."

Cable showed a circular device on his wrist to Deadpool. For futuristic tech, it seemed rather old, and above it was a miniature screen with the number one on it.

"Hmm, so I see the author decided to take the Deadpool 2 approach and make your time travel abilities tech-based instead of a mutant ability. In that case, our current predicament is the result of lazy writing," Said Deadpool.

"I don't suppose you two have the Blackbird, do you?" Asked Cable to Domino and Psylocke.

"Oh, oh! Can I fly the Blackbird again?!" Asked Deadpool excitedly.

"FUCK NO!" Shouted all of Deadpool's friends

"Oh, just because I crashed the Blackbird on the front lawn of the X-Mansion ONE time, I am not allowed to pilot it anymore!"

"You struck Logan when you crashed!" Said Psylocke.

"Scruffy's got a healing factor like me. He survived that unscathed."

"Ignoring your terrible piloting skills, we can't use it anyway. The Blackbird is currently taking a small team of X-Ponies to Equidor. Supposedly, Mister Sinister sent a clone of Blob there. We were both dropped off here on the way there," Said Domino.

"Damn it! How are we going to get to Genosha now?" Pondered Cable irritatedly.

Deadpool thought about how he and his friends could get to Genosha. Then an idea came into his head.

"Oh, oh! I know how we can get there!" Said Deadpool excitedly.

"This better not be another one of your old 'Uber' jokes. Whatever that is," Said Psylocke.

"Please, even I know that cars can't drive over water. Not yet anyway, right?" Asked Deadpool while lightly elbowing Cable and winking at him.

"Wade, spit it out!" Said Cable irritatedly.

"There is one pony nearby who I think can help us - Twilight Sparkle."

All of Deadpool's friends looked at him with raised eyebrows.

"Twilight Sparkle? As in the newly appointed Princess?" Questioned Domino skeptically.

"No, I'm talking about the old pegasus mare that lives on Hay Haven. Of course I'm talking about the Princess of Friendship! She knows a lot about magic. She might have a teleportation spell that could take us to Genosha," Said Deadpool.

"I'll admit, that actually isn't a bad idea," Said Psylocke.

"Well, if this is a princess we are talking about, we don't have time to make an appointment to have an audience and plead our case," Said Cable.

"We don't need to make an appointment. I can take you all directly to her since I'm part of her social circle," Said Deadpool.

"You are?" Questioned all of Deadpool's friends in unison.

"Yes, I am! Do any of you read the newspaper?! I appeared on the cover with her on two different occasions. The first time when she and our friends defeated Discord, and the other time on the day of her coronation; also with our friends. I am also mentioned in the paper covering the royal Canterlot wedding, but not for good reasons. Besides that, I'll let you know that I am her coltfriend."

There was silence, but that was replaced with laughter from Domino and Psylocke.

"Wow! Your jokes are normally very annoying, but that was actually funny, Wade!" Said Domino.

"I'M SERIOUS! She and I have been dating for a couple of months now! Is that really hard to believe?! Asked Deadpool.

"Considering this is YOU we are talking about, yes," Said Psylocke.

"I… I! Come on, Cable, back me up! You're from the future, you must know! In future Equestrian History class, you must have learned about the reign of Princess Twilight Sparkle and Prince Deadpool!"

Cable looked at Deadpool with a stone-faced look. This only irritated Deadpool even more.

"Gurrr… That's it! I'll take you all to the Golden Oak Library, and prove that Twilight and I are in a romantic relationship!"

Deadpool directed his friends towards the direction of the Golden Oak Library. After a few minutes, the group arrived at the Golden Oak Library. Deadpool walked up to the front door and knocked on it.

KNOCK! KNOCK!

"I'll show all of you that I'm capable of attracting princesses," Said Deadpool irritatedly.

"Who is it?" Asked Twilight from the other side of the door.

"Jehovah's Witnesses," Answered Deadpool.

The door opened up, revealing Twilight on the other side.

"Hi, Wade. Where are the gro-"

MUAH!

Before Twilight could ask her question, Deadpool quickly grabbed her, and pulled her into a kiss. Twilight was, reasonably, surprised by the action, but then melted into the kiss. Deadpool glanced back at his friends, and saw the shocked expressions on their faces. Even the normally collected Cable had his jaw dropped. A devilish smirk was noticeable from the corner of his mouth. Once he finished proving his point, he let Twilight go. She had a dopey smile with a dark red blush on her face.

"Wow... What was that for, Wade?" Asked Twilight lovingly.

"'Cause I love you," Answered Wade.

"Aw! Love you, too."

Both Twilight and Deadpool leaned in for another kiss. Twilight looked behind Deadpool, and realized that they had company.

"Oh! Uh… I-I didn't know you had company, Wade," Said Twilight, blushing profusely out of embarrassment.

When they were noticed by the Princess of Friendship, Deadpool's friends removed the shocked expressions on their faces, and made themselves look presentable.

"These guys? They're just some old friends of mine," Answered Deadpool. "Allow me to introduce you to them. The stallion on the right is the time travelling badass, Josh Brolin- I mean Cable! The mare on the left is Domino, who is maybe, possibly mildly lucky. And finally, the mare standing between them is the lethal telepath, Psylocke."

Deadpool's friends bowed before Twilight. Twilight blushed out of slight embarrassment, but kept a grin on her face.

"Princess Twilight Sparkle, we are in need of your assistance," Said Cable.

"I'll help in any way I can. What seems to be the problem?" Asked Twilight.

"A mad geneticist by the name of Nathaniel Essex, aka Mister Sinister, is plotting to take over the world with a clone army. If he succeeds, then he will instill his idea of genetic perfection onto the world. We are going to face him at his hideout on the island of Genosha, but we don't have a means of getting there. Deadpool informed us that you may be able to help us," Said Cable.

"You're in luck. I know of a teleportation spell that will be able to take you to Genosha, or anywhere else in the world in that matter, instantly. I'll just have a quick look at a map, so I can have a mental image of where I am transporting you."

Twilight walked over to a desk, and opened a draw. She pulled out a map, and unrolled it on the desktop. It was a world map with many regions, including Equestria, laid out across its surface.

"So, how do you all know each other?" Asked Twilight.

"Well, we've been on multiple world-saving adventures together before," Said Domino.

"And we were part of a group called X-Force, and we're back together again!" Said Deadpool.

Once again, Deadpool's friends groaned out of exasperation.

"X-Force? What is that?" Asked Twilight.

"I'll show you!"

Deadpool ran downstairs quickly, and returned just as quickly. He held a photo album in his hooves.

"X-Force was a covert black-ops team that did missions that most heroes wouldn't get involved with. There was usually a lot of bloody murder involved. Aw, we were so young and hip."

Deadpool opened up the photo album, and looked at a photo that had him, Cable, Domino, and Psylocke all together in heroic poses. They were all strangely wearing outfits from the 1970s, including Deadpool. He was wearing a red and black leisure suit, and he had an afro on his head.

"We looked NOTHING like that," Said Cable.

"And you lost all of your hair during the experiments that gave you your healing factor," Added Domino.

"The point is, X-Force was awesome, and now we're back together. Kind of like a band," Said Deadpool.

Twilight looked at the world map for a few more seconds before looking back up at the group.

"Here it is. Genosha is located northeast of Madagistar. I should be able to teleport you all there, so you can stop Mister Sinister," Said Twilight.

"See guys? I told you that my girl would be able to help us," Said Deadpool.

"Yeah, you were right, Wade. And sorry for not believing that you were going out with her. I just couldn't believe that you got together with one of the Princesses of Equestria after you and I broke up," Said Domino.

Right after Domino spoke, the sound of a record player stopping abruptly could somehow be heard in the room. Twilight dropped the map onto the floor, and Deadpool looked terrified.

(Oh shit!)

"Wade, what is she talking about?" Asked Twilight.

(Well, we are about to lose our balls!)

"Wade?! I said what is she talking about?!" Asked Twilight irritatedly.

"Uhhhhh… She said she couldn't believe that you and I got together since the last time she and I met up," Said Deadpool very, very nervously.

"You're lying to me, Wade! Your voice gets higher when you lie."

"No it doesn't," Said Deadpool in an obviously high pitch.

(Damn it! Our Canadian heritage prevents us from lying effectively!)

"I'm going to give you one last chance to tell the truth. I would suggest choosing your next words carefully," Warned Twilight.

"Okay, fine! Domino is my ex marefriend," Said Deadpool.

"Oh, wait. You never told her about… Um, sorry," Said Domino.

"Thanks a lot!" Said Deadpool irritatedly.

"I would like a word with you in private!"

Twilight used her magic to grab Deadpool by the ear, and practically dragged him downstairs. Once they were in the living room, she let him go.

"You have some nerve, Wade!" Said Twilight angrily.

"What did I do?!" Asked Deadpool defensively.

"I knew you have been in other relationships besides ours, notably your relationship with Vanessa. But you never said anything about Domino!" Said Twilight.

"Does it really matter?!" Asked Deadpool.

"Yes, it does! We're in a relationship, Wade. We shouldn't be keeping these kinds of secrets from each other. I know it isn't a topic that is easy to discuss about, but we've known each other for a long time, and have been together for a couple months now. I feel like I deserve to know," Said Twilight.

"I suppose I could tell you about all of my past relationships. It would be a lengthy talk, since I went out with twenty-eight-"

(Ah-Ahem!)

"Ugh! Thirty mares, including Domino. We can talk about it later. Right now, we have to head to Genosha."

Before Deadpool could head back upstairs, Twilight grabbed him by the shoulder.

"And that's another thing. You have just met up with her after not seeing each other for a long time, and you're tagging along with her?" Questioned Twilight.

"Please, I'm going with Psylocke and Cable as well. And it's not like we are all going on a vacation to Mancún. We're going to save the world from a vampire-like madman and his mutant clone army. Joining up with Domino is out of altruistism instead of infatuation," Said Deadpool.

"I… I guess that is true,"

"Not trying to poke the bear or anything, Twi, but it seems like you may be a little jealous of Domino,"

"Pfft! What?! Me jealous of her?! Why would I be jealous? I mean, she calls herself 'Domino'?! How did she come up with that nickname anyway?" Asked Twilight.

"She was given the moniker Domino because her (air quote) 'probability alteration power' causes things to fall into place for her," Answered Deadpool.

"That's… actually very creative. Darn!" Said Twilight frustratedly.

"Twilight."

"Okay, I'm jealous! I've only met her for a few minutes, and I can already see that you have much more in common with her than with me. You're both superpowered ponies, have mercenary backgrounds, and you are both trained marksponies and fighters."

"Maybe so, but you and I have a lot in common, too."

"Like what?" Asked Twilight.

"Uh, we both have the same best friends," Said Deadpool.

"Right."

"We are both fictional characters."

"Wade be serious."

"I am! We both have irrational fears. I'm afraid of chickens and clowns, and you're afraid of ladybugs and quesadillas."

"I am not afraid of quesadillas! They're just so… cheesy," Said Twilight while shuddering.

"And I think clowns are the greatest threat to Earth after Galactus! See, we have plenty of things in common!" Said Deadpool.

"I suppose we do," Said Twilight.

"Are there other reasons why you're jealous of her?" Asked Deadpool.

"Well, I am also envious of her looks. She's got a great mane, a slim figure… a decent sized flank…"

([Snort] Sorry! I know this is a serious conversation involving relationship insecurity, which is a totally normal feeling to have in a healthy relationship, but I can't help but laugh at the fact that a character from a toy line's show adaptation just compared her ass size with someone else's!)

SNIFFLE!

Without warning, Twilight began to sniffle, and her eyes grew teary.

"Twilight…" Said Deadpool sympathetically.

"I'm sorry. I know I shouldn't be envious, and I know that you wouldn't leave me for her, but I still can't help but feel insecure. I'm afraid that if you go to Genosha with Domino and your friends, you would find that you would be happier with her than with me."

Deadpool gently grabbed Twilight by the shoulders, guided her to the couch, and sat her down.

"Twilight, look at me," Said Deadpool.

Twilight looked Deadpool in the eyes, and he took one of her hooves in his.

"You have nothing to worry about. I may have loved Domino once, but we have run our course. You are the only one for me. I love you, and that will never change. We may not have too much in common, but that will change when we try out each other's interests, and share new experiences together. As for appearances, Domino may be attractive, but you are the most beautiful pony I have ever met. Your mane is long, luxurious, and that pink hairstreak drives me wild!"

Deadpool grabbed a strand of hair from Twilight's hairstreak, and twirled it gently. This made Twilight smile a little.

"Your figure is magnificent, as if you were sculpted from clay by gods! Now that I think about it, I suppose Lauren Faust is a goddess. And if you think I don't like your butt…"

"Ah!"

Twilight felt Deadpool pinch her butt, which caused her to jump a little. She retaliated by playfully pushing him.

"Wade!" Said Twilight.

"My point being, I love you, Twilight. No one will ever take me away from you. And if it makes you feel better, Domino and I had a mutual breakup. She and I agreed that we were better off as colleagues, friends at best."

Deadpool and Twilight embraced each other in a hug, and Twilight wiped the tears from her eyes.

"Thank you, Wade. I love you," Said Twilight affectionately.

"I love you too, Twilight," Replied Deadpool affectionately.

As they held each other in an embrace, an idea popped in Deadpool's head, which caused him to smirk under his mask.

"I just thought of one more thing that you and I share," Said Deadpool.

"Oh, and that is?" Questioned Twilight.

"We both love to DANCE!"

Deadpool grabbed Twilight by the foreleg, and pulled her up from the couch, surprising her a little. He had her stand on her hindlegs, and wrapped his right foreleg around her back. Following his lead, they danced the waltz. They both looked into each other's eyes, and smiled lovingly. Suddenly, Deadpool hummed a tune from a classic romance film. Then he lightly sang…

"Tale as old as time. Song as old as rhyme. Beauty and the fucked up mercenary," Sang Deadpool.

"Oh, quiet you!" Said Twilight affectionately.

Suddenly, Deadpool switched their dance from the waltz into the tango.

"Eeek!" Cried Twilight out of shock.

"Ohhhh! This mare is my destiny! She said oh oh oh! Shut up and dance with me!" Sang Deadpool.

Twilight laughed out of pure joy. To wrap up their dance, Deadpool slightly loosened his grip on Twilight, causing her to dip backwards. Pulling her back up, they both chuckled. Twilight lifted up Deadpool's mask slightly, and kissed him.

"Ah-Ahem."

Looking behind them, they found Psylocke standing in the doorway. They both blushed a little out of embarrassment, while Psylocke looked at them with a stone-faced look.

"I'd hate to interrupt this touching moment between you two, but we have to get going," Said Psylocke.

"Oh, right. We'll be right up," Said Twilight.

With a nod of her head, Psylocke went back upstairs.

"Guess it's time to go save the world," Said Deadpool.

On that note, both Deadpool and Twilight went upstairs. Once they were in the main library, Deadpool stood next to his friends.

"You know, I could tag along as well," Said Twilight.

"Thank you, Princess Twilight, but we'll take care of Sinister ourselves. It would also be safer if you stayed here instead of coming with us," Said Cable.

"Well, don't you need somepony to teleport you all back when you are done?" Asked Twilight.

"Yes, but we will let you know when the time comes," Answered Cable.

"You will? How?" Asked Twilight.

"Like this."

Twilight could hear Psylocke, but she didn't see her move her lips to talk. That was when the answer hit her.

"Oh, right. You're telepathic," Said Twilight.

"I can also speak to you telepathically as well, should the need arise," Said Cable telepathically.

"Well then, let's get you all on your way," Said Twilight.

Twilight closed her eyes, and concentrated on her thoughts. She pictured the world map she studied in her mind, and focused on Genosha. The tip of her horn glowed with a magenta light, and she cast a beam of magic towards Deadpool and friends. The magical beam wrapped around the group, bathing them in a magenta light. Then in a flash, their vision turned white. Their vision returned to normal quickly, revealing that they were no longer at the Golden Oak Library. All around them were the ruins of buildings. A once thriving civilization was now left in shambles.

"Looks like we were successfully teleported to Genosha," Said Domino.

"Indeed. Now that we are here, we need to find Sinister and bring him down," Said Cable.

"Do you have any ideas on where he could be hiding?" Asked Psylocke.

"Magneto's old citadel is a good place to start. If we can get a move on, we can get there before 15:00," Said Cable.

"Can we just take a moment to take in the scenery?" Deadpool was taking pictures of the ruined city. "This place is riddled with history. Mostly terrible, but I'm sure there was something good that came out of this hellish island. And I swear I've been here for something with a similar plot as this chapter!"

Ignoring Deadpool, Psylocke and Cable walked straight ahead. As Deadpool was about to follow them, he felt a hoof grab his shoulder. He saw that the hoof belonged to Domino.

"Wade, is everything alright between you and Twilight?" Asked Domino.

"Of course everything's fine. Why wouldn't it be?" Asked Deadpool in reply.

"Well, I did drop a big bombshell on her when I mentioned us," Answered Domino.

"Maybe so, but it wouldn't have happened in the first place had I actually told her way beforehand," Said Deadpool.

"So, are we cool?" Asked Domino.

"Oh, Dommie, I could never stay mad at you!"

Deadpool hugged Domino, much to her surprise. He then skipped after Cable and Psylocke. Domino followed after him, bearing a confused look. After about an hour's walk, the group of heroes stumbled upon an eerie sight. Sitting in front of them were the rusty remains of a three story tall, metallic equine. One of its forelegs was detached from the body, and one of its metallic eyes was loose, dangling from large wires.

"Wow! To think that these things wiped out almost all of the inhabitants on this island," Said Wade in astonishment.

(Yes, very terrible indeed. Although I can't help but wonder how the Sentinels work in this universe? If I were to give my best judgement of the technological advancement of Equestria and presumably the majority of the world, it would be similar to 19th or early 20th century technology in the real world.)

(Magic is an integral part of this world, so perhaps the Sentinels are comprised of both science and magic? Like they are made through modern engineering and robotics, but are powered by a magic based source?)

KLANG!

"Someone's here!" Said Cable.

Hearing the sound of metal falling to the ground, the group stood together back to back. Deadpool and Domino pulled out a pair of pistols, Cable pulled out a high-powered plasma rifle, and Psylocke summoned a katana made of psychic energy, which caused an aura shaped like a butterfly to appear on her face.

"I can sense someone's close by. They are circling us," Said Psylocke.

As everyone looked around for the enemy, the sound of trotting hooves could be heard, and they grew louder with every passing second. The hoofsteps mysteriously went silent, putting everyone on edge. Domino looked up towards the looming Sentinel, and noticed a silhouette of a pony perched on top of the robot's head. She blinked her eyes, and it leaped towards her.

"In front of me!"

BANG! BANG!

Domino shot at the pony, only for it to dodge the bullets mid air. It landed on the ground in front of her, revealing more of its features. They were a brown coated earth pony stallion, with an unkempt yellow mane and tail. They had claws on all four of his hooves, and a pair of fangs. Over his torso, he wore a brown coat with white fur around the neck.

"It's a clone of Victor Creed!" Said Domino.

"How do we know he's a clone and not the actual Sabretooth? I'm still fine with the outcome of killing this asshole regardless, but, you know, for story purposes," Said Deadpool.

"Maybe he has a tag on the back of his coat?" Suggested Domino.

The clone of Sabretooth leapt towards the group. They all separated and dodged out of the way. Looking at his back, Deadpool saw the tag Domino suggested. It had Mister Sinister's name on it, along with the number VC-1977.

"Really? That's how you know that he's…? That has to be the laziest way of introducing your 'good luck power'!" Said Deadpool.

The clone ran towards Cable. He aimed his rifle at the clone, and shot a couple plasma charges at him. The clone dodged all of the shots, and pounced. Cable put his rifle on his back, moved to the side, and grabbed the clone by the arm. He threw him onto the ground, and slammed one of his hooves towards his head. The clone rolled out of the way, and scratched Cable's arm.

SCRATCH!

Cable retaliated by back-hoofing the clone, sending him flying into the Sentinel. He recovered quickly, and kicked towards Cable's head. Cable blocked the kicks by using his bionic arm as a shield. Sabretooth's clone followed his attack by low sweeping Cable's hind legs, causing him to fall on his back. The clone drove his claws towards Cable's neck, but before they could make contact, they were blocked. Psylocke held a psionic katana in front of Cable to block the killing blow, and pushed the clone back.

"You're not the only one who is vicious!" Said Psylocke.

Psylocke thrusted her psionic blade towards the clone, only for him to dodge it. He swiped at her, but none of his claws managed to cut her. She kicked him in the stomach, then cut his throat open. This proved to have no effect, as his wound instantly healed.

"Wade's got a healing factor, Logan's got a healing factor, Victor and his clone have a healing factor. Who doesn't have a healing factor these days?" Asked Psylocke.

Psylocke swung her blade at the clone, slicing through his skin. The attacks didn't slow him down, only making him angrier. With a growl of a feral animal, he lunged at her.

CHOMP!

AHHHHH!

The clone bit down on Psylocke's left arm, causing her to drop her katana. She managed to pry him off with the help of telekinesis before he could do any more damage. He flung his forelegs and hind legs at her. She dodged all of his attacks, and she prepared to counter. Before she could, however, the clone delivered an uppercut to her jaw, launching her into the air.

POW!

SLAM!

As she fell towards the ground, the clone grabbed her face, and slammed her into the ground. Ready to deliver the killing blow, he drove his claws towards her chest.

"PSYLOCKE!" Cried Deadpool, Domino, and Cable.

SNAP!

Suddenly, a loud metallic snap could be heard from above. As the clone looked up, he saw the Sentinel's dangling eye detach from the wires, and fall towards him.

THUD!

Hitting him straight in the head, the clone fell over on his side with his cranium smashed in. Psylocke got up, holding her injured arm. Her friends sighed in relief.

"Phew! I may be the one with probability powers, but YOU are lucky, Betsy!" Said Domino.

"Well, I'm pretty sure that has your name written all over it," Countered Psylocke.

"Now THAT'S how you introduce a superpower based on luck! Go X-Force!" Said Deadpool.

"Ugh!" Groaned Deadpool's friends exasperatedly.

GRRRR!

To everyone's surprise, the clone got back up. Even with his head healing from being smashed in, he was still able to fight.

"Forget Sabretooth, this guy ought to be called Cockroach! Nothing kills this bastard! Nothing except maybe this baby!"

Out of nowhere, Deadpool pulled out a single sword, and lunged towards the clone. He managed to make a small cut on the clone's arm, causing him to growl in pain. While the clone's head had now fully healed, the cut hadn't even begun to heal.

"Is that what I think it is?" Asked Psylocke.

"Yup, the Muramasa Blade. Taskmaster tried to kill me with this in the very first chapter of this story. I took it when I bested him, and held onto it in case I would ever need it. I grabbed it earlier when I was downstairs looking for that photo album. I figured if worst comes to worst, we can use it on Mister Sinister," Said Deadpool.

Deadpool lunged at the clone, sword swinging. With every swing of his blade, the clone dodged quickly. In a rather inelegant manner, Deadpool held the blade above his head, and ran towards the clone. He thrust his sword towards his opponent's head, only for it to be dodged swiftly. He then swung the sword around like he was trying to hit a piñata with a baseball bat while wearing a blindfold. The clone of Sabretooth effortlessly dodged each swing, and seemed to look unimpressed at his adversary's swordsmen skills. From the sidelines, all of Deadpool's friends were just as unimpressed.

"Wade, stop swinging your sword like a little foal with a branch! You're supposed to be skilled in swordsmanship!" Said Domino irritatedly.

"I'll have you know that I am a master when it comes to swords! Especially my personal sword, which you have seen in action!" Said Deadpool.

"Are we really talking about that now?!" Asked Domino rhetorically.

With Deadpool focused on Domino more than the fight, the Sabretooth clone took the opportunity to scratch his arms, causing him to drop the Muramasa Blade. He then kicked it away, much to the terror of the Merc with a Mouth.

"... Fuck," Muttered Deadpool timidly.

The clone lunged towards Deadpool, and he ran off. With the clone in hot pursuit, Deadpool tried to find a way to gain an advantage over his pursuer. Deadpool looked at the Sentinel, and got an idea. With great speed, he climbed up the Sentinel, leaving Sabretooth on the ground.

"Ah-ha! It's over, flea-bag! I have the high ground! You may be able to climb, but that won't save you from the most overpowered weapon in warfare!" Said Deadpool.

Not deterred from having a height disadvantage, the clone climbed up the Sentinel.

"You're asking for a death wish, pal. Have you ever read 'The Art of War'? It says in bold 'Do not try to fuck with the high ground'."

Deadpool pulled out one of his pistols and shot at the clone. The clone dodged each shot, gaining speed as he got closer. He then grabbed Deadpool by the hind leg, and held him upside down, with the ground eerily below.

"Ahhhh! Ewan McGreggor never mentioned the high ground could be beaten!" Said Deadpool fearfully.

(Well, he did beat Darth Maul in 'The Phantom Menace', and the Sith Lord had the high ground then.)

"Touché."

Seeing Deadpool's current predicament, Cable pulled out his rifle and shot a plasma charge. It struck the clone, and both him and Deadpool fell towards the ground. Reacting quickly, Psylocke used her telekinesis to grab the Muramasa Blade, and tossed it towards the clone.

SHULK!

"Gugh!"

Striking dead center in the chest, the Muramasa Blade killed the clone of Sabretooth, thanks to its mystic properties negating his healing factor. He landed on his back with the blade pierced through his chest. As for Deadpool, before he could hit the ground, Cable managed to catch him in his arms.

"Wade, are you alright?" Asked Cable.

Terrified from the attack, the Merc shaked in his savior's grasp.

"Look at me."

Doing as he was told, Deadpool looked at Cable, already beginning to calm down.

"Are you alright?" Asked Cable.

"... You're so cute."

THUD!

"Yup, you're fine," Deadpanned Cable.

Purposely dropping Deadpool, Cable walked over to the deceased clone of Sabretooth. He turned over the body, and pulled out the Muramasa Blade. He then handed it over to Deadpool.

"While you need to work on your fighting skills, great thinking on bringing the Muramasa Blade along," Commended Cable.

"What can I say? I'm full of 'sharp' ideas," Replied Deadpool.

(Boo! You stink!)

"Hold still, and let me look at it!"

Both stallions looked over and saw Domino and Psylocke in a bit of a scuffle. The former was trying to examine the latter's arm, which had been bitten by Sabretooth's clone. Her arm was bleeding profusely, blood staining a good portion of the upper half.

"I don't need you to look at it; I'm fine," Said Psylocke.

"Fine?! You were just bitten by an overgrown weasel! You need to cover that up to at least slow the bleeding!" Said Domino.

"It's just a flesh wound. I'll live."

"At least let me wrap a bandage around your wound."

Deadpool walked up to Psylocke with medical bandages, gauze, and a bottle of saline solution, all of which he pulled out of nowhere. Psylocke looked at him then the medical supplies. With a roll of her eyes, Psylocke allowed him to dress her wound. Starting with the saline, he gently coated the puncture wounds using a cotton swab.

"Why would you of all ponies carry medical supplies?" Asked Domino.

"'Cause everyone I care about and protect doesn't have a healing factor like me. For me, stab wounds heal in seconds, a broken bone would properly heal without a cast, and if anything fell off, well, it can pop back on or I just regenerate a new one. But for all of my friends, for Twilight, any injury could mean the difference between life and death. So, combined with basic first aid skills I learned while in the Special Forces, I try to prepare for any medical emergency," Explained Deadpool.

"Aw, that's actually very sweet, Wade," Said Domino.

After cleaning the bite wound, Deadpool packed the wound using the medical bandages. Once the bandage was wrapped on tightly, but not too tight that it would restrict blood flow, Psylocke moved around to make sure movement of her arm wasn't restricted too much.

"I would advise you to sit this one out and maybe return to Ponyville to receive some medical attention, but knowing you, you will not stop until we wrap up Mister Sinister into a nice little bow. So, have some whisky."

Deadpool handed over a flask of whisky to Psylocke, which she drank in one sip before tossing the flask aside.

BZZT! BZZT!

A buzzing sound could be heard nearby. Searching for the source of the sound, Cable pinpointed the sound was coming from the clone's corpse. Reaching into the clone's coat, he pulled out an emblem in the shape of a red diamond. Pressing a red button in the center of the emblem, a projection appeared above it. It revealed the face of a unicorn stallion. He had white fur, red pupiless eyes, and a long black mane with a distinctive widows peak. In the center of his forehead rested a red diamond.

"I must say, I am a little surprised to see you here, Summers. I figured you and your allies would be preoccupied with my army," Said the stallion.

"You are correct, Sinister, in that our allies have their hooves full with stopping your clones, but we were able to come here and deal with you personally," Replied Cable.

"We? So, there are others with you? Excellent. I can study my test subjects' combat capabilities while you all try to stop me. Based on our current interaction, I can see that you have bested VC-1977."

"We have the Muramasa Blade in our possession. Any clones with healing factors you send at us will be no match for us. And if you are not careful, you will find that it will be lodged up your ass."

"Oh, oh! Can I have a turn talking to Mister Sinister?! I want to tell him how my date with his mom went!" Said Deadpool.

"Deadpool! You brought the repulsive mutate along with you?! Thankfully once I carry out my plans of genetic perfection, defects such as him will be removed from this world," Said Sinister.

"Wow, how very Nazi of you to say."

"No matter, I have more pressing matters to attend to. If you think you are strong enough to face my army, find me at an abandoned laboratory about an hour's walk from the Sentinel you are currently at. But I will only warn you once, if you dare challenge me, you will all meet a swift end, and I will use your genetic material to create more loyal clones."

On that note, the transmission ended. Cable placed the emblem on the ground, and crushed it under his hoof.

"You all heard him, we're moving out," Ordered Cable.

With Cable leading the way, the group of heroes made their way to Mister Sinister's current location. The walk was mostly uneventful, with everyone keeping to themselves. Eventually, they arrived at what appeared to be a small, rundown scientific laboratory, located next to a cliff. The building was overgrown with the local flora, parts of the ceiling caved in, and many of the windows were shattered.

"What a dump," Said Deadpool.

"It may not seem like it, but Mister Sinister probably has the rest of his army hidden in there. It could also be full of booby traps," Said Domino.

"Ha ha ha! You said traps!" Said Deadpool.

(Wait! Did somepony say BOOBS?!)

"Yeah, Domino said that," Said Deadpool to his inner voice.

(Ah, yes. There's nothing in life like a mare's breasts.)

(Oh! Since we've been a pony in this fanfiction for a while now, which of these are the best: chest boobies or crotch boobies?)

"Hmmm… That's a toughie; they're both great. I guess if I had to choose one, I would say crotch boobies are the best."

(Why?)

"Less distance to cover during or-"

"Wade! Have you been paying attention?" Asked Domino.

"Uh, you lost me at traps," Answered Deadpool.

"Ugh! Just keep your guard up and watch your step when we're inside."

Domino, Cable, and Psylocke entered the laboratory with Deadpool following behind them. Unbeknownst to them, four equine shadows could be seen on the ground behind them. Entering through the main entrance, the group noticed the interior of the laboratory was just as bad as the outside. Walking down a large hallway, broken furniture, damaged scientific equipment, rubble, and the occasional remains of a mutant could be found. Eventually, they reached the end of the hallway, where it branched off into four more.

"Four halls, and most likely one could lead us to Mister Sinister. Can you tell where he is, Psylocke?" Asked Cable.

"Hmm… No, he's masking his presence. We'll have to find him the old fashioned way," Said Psylocke.

"Unless Domino is lucky and finds the right path?" Suggested Deadpool.

"I would say we have a better chance if we split up and take a hallway each," Said Domino.

"Very well. I created a mind link between the four of us. If any of us find Sinister or a good lead of his location, we can tell each other through our thoughts. Everyone choose a hallway and begin searching."

On Cable's order, the heroes split up and went down their own hallway. Cable went down the first hallway on the left, Psylocke the second to the left, Domino second to the right, and Deadpool down the first hallway on the right. They all failed to notice the shadows that were looming behind them. As he was walking down the hall, Deadpool was whistling a little tune to himself to keep himself entertained. Suddenly, he heard hoofsteps behind him. He turned around, only to find Psylocke behind him.

"Oh, hey. Uh, what are you doing here, Psy?" Asked Deadpool.

Psylocke walked up to Deadpool, then, before he could react, she grabbed the Muramasa Blade from his hoof and restrained him, bringing the blade to his neck.

"Psylocke, what's the meaning of this?!" Asked Deadpool in shock.

Psylocke didn't answer him. Instead, she tightened her grip on the Muramasa Blade, and prepared to slit Deadpool's throat.

"Have you ever wondered why I always wear red?" Asked Deadpool nonchalantly.

Not expecting the question Deadpool asked her, Psylocke subconsciously loosened her grip when she looked at him with a confused look. This gave him enough room to move his arm and jab her in the rib cage with his elbow. Due to the sharp pain caused by the jab, she dropped the Muramasa Blade onto the floor and let him go. Deadpool grabbed the Muramasa Blade and stashed it somewhere on his person. Recovering from the attack, Psylocke ran towards him.

"I hate that you are making me do this, Elizabeth."

Running towards her as well, Deadpool through a punch towards her at the same time she did. They both managed to punch each other at the same time, causing them to fall over onto their backs.

Meanwhile, in one of the other hallways, Psylocke was searching for any signs of Mister Sinister. Her injured foreleg gave her a little bit of a limp, but it didn't deter her from moving forward. She stopped in the middle of the hallway. She detected someone's presence thanks to her telepathic abilities. Checking her surroundings, she found Cable standing behind her.

"Cable, did you find any clues as to where Mister Sinister would be? If you did, I'm surprised you didn't communicate to me through our mind link," Said Psylocke.

Cable calmly walked over to Psylocke. Despite being fairly taller than the average mare, she was still short compared to Cable's looming height.

WHACK!

Before she could even react, Psylocke was back hoofed by Cable's bionic arm. She was sent flying back by his arm's immense physical strength.

"Cable! What the hell?!" Said Psylocke angrily.

Cable ran up towards her and threw more punches her way. She managed to create a telekinetic shield just in time to absorb all the blows.

"What has gotten into you, Summers?!" Asked Psylocke irritatedly.

Before he could deliver another punch, Psylocke used her shield to push Cable back. Only sliding a few feet, Cable ran up to deliver another punch, only to be blocked by a smaller shield in one of Psylocke's hooves, and was punched in the face with the other. Running then jumping into the air, Cable was ready to slam his front hoof into Psylocke, while she summoned a shield around herself.

Meanwhile, Cable was walking through a hallway like Psylocke and Deadpool. He didn't get very far before he heard a feminine voice say…

"Ah-Ahem!"

Turning around, he found Domino walking towards him.

"Domino, what are you doing here? You should be investigating your hallway, and contact us when you find anything," Said Cable.

Domino kept walking towards him, and then leapt up and bucked him straight in the jaw. Grabbing his jaw in pain, Cable looked at her with a shocked expression.

"What is the meaning of this, Domino?!" Asked Cable.

Ignoring his question, Domino kicked him in the abdomen, then grabbed his organic arm and pinned him to the ground.

"Fine then, be that way."

Cable effortlessly shaked Domino off of him, even with one of his arms behind his back. While she was recovering from being tossed off, he ran up to her and tackled her into a wall.

Meanwhile, Domino was walking down her hallway. Unbeknownst to her, a figure was following her from behind. They raised a hoof, ready to strike her head. She stepped over a metal pipe, which her pursuer failed to notice and tripped.

KLANG!

Hearing them trip, Domino looked behind her and saw Deadpool, laying face first on the ground. She extended a forehoof in front of him.

"Need a hoof, klutz?" Asked Domino.

Deadpool reached out and grabbed her hoof. As soon as she helped him up, however, he tightened his grip on her hoof, and spun her around. He pressed her face against a wall, and held her arm behind her back.

"Wade, if this is some fucked up joke you're pulling on me, I will beat you upside the head! Now, let me go!" Demanded Domino.

Deadpool didn't listen, and he grabbed her head with his free hoof. He slowly twisted her neck to the left. Knowing what he was planning to do, she tried to struggle free but to no avail. It would be only a matter of seconds before Deadpool snapped her neck.

CREAK!

FWOOSH!

Just before she could've been killed, a water pipe built into the ceiling above burst, spraying Deadpool with a large amount of water. Frantically running out of the stream of water, he let go of her, allowing her the opportunity to pull out her pistols and fire at him. He dodged all of the shots, and grabbed the pipe that he tripped on. He swung it towards her, but she swiftly dodged each swing.

"Wade, what is wrong with you?!" Asked Domino.

"Hey, can anyone hear me? If so, I need help!"

Domino could hear Deadpool talking, but it sounded like it was coming from her head. That was when she remembered the mind link.

"Wade, I can hear you talking to me, but you're currently attacking me!" Said Domino.

"Okay, Zazie Beetz, I'm afraid your accusation is a bunch of bullshit! I'm currently being attacked by Psylocke!" Said Deadpool.

"I can hear both of you. And I can also say that is a bunch of bullshit! I'm preoccupied with defending myself from Cable!" Said Psylocke.

"Hmm, curious. I'm currently being attacked by Domino, but if I heard her correctly, she said she's fighting Deadpool. Do you know what this means?" Questioned Cable.

"We all have twins that neither of us were aware of?" Asked Deadpool.

"No, it means we are all dealing with doppelgangers,"

"Are they clones of us, or somebody with shapeshifting abilities?" Asked Psylocke.

"Let's find out."

Domino fired more shots at Deadpool's doppelganger, but he dodged all of the shots. He then ran up to her, and smacked both of her pistols out of her hooves. He then kicked her, causing her to fall onto her back. She used her horn to grab one of her guns using her magic. Before she could fire a shot, Deadpool's doppelganger stepped on the gun's side, pinning it to the ground. Pipe in hoof, the doppelganger readied himself to strike her head. Even though she knew her gun wasn't aimed at him, she fired a bullet anyway.

BANG!

DING! DING!

The single bullet fired ricocheted off of multiple objects throughout the hall. It then ricocheted off of a sign hanging from the ceiling, and headed towards the impostor.

"Gugh!"

The bullet went through the impostor's head, leaving a gaping bullet wound in the center of his forehead. As he fell over backwards, his form changed. He changed into someone Domino was unfortunately familiar with. The impostor was a dark blue unicorn mare with a long, sleek red mane, and yellow eyes.

"Guess what everyone? I just killed Wade's doppelganger, and it seems that they were a clone of our old friend, Mystique," Said Domino.

"Oh, that's great!" Said Deadpool sarcastically.

Meanwhile, Deadpool was in a mini wrestling match with Mystique's clone disguised as Psylocke. They were both trying to outclass the other in terms of strength.

"This is just great. First I met up with my ex, Domino, nearly had my nuts cut off by my current marefriend because I didn't tell her about us, and now I'm fighting a clone of one of my other exes. This day has been going absolutely swimmingly!" Said Deadpool sarcastically.

(We may have all of our exes showing up and biting us in the ass, not in the fun way, but this just shows that we know our way around the mares.)

"Wait, if she's a clone, then that means…"

THUD!

With a mischievous smirk visible under his mask, Deadpool smacked his forehead against the clone's face. Stumbling backwards, the clone only had enough time to see Deadpool pull out his katanas.

SHLING!

Faster than the eye could perceive, Deadpool made two strokes with his katanas. The clone's head and torso slid off, the dismembered body reverting to Mystique's form. Satisfied with his victory, Deadpool put his swords away.

Meanwhile, Psylocke was using her telekinetic shield to absorb the clone disguised as Cable's punches. With the butterfly-shaped aura appearing on her face, she formed a psionic dagger in one of her hooves. When the clone was about to punch the shield again, she made it disappear. Not expecting this, the clone lost balance when they made no contact with their target. Taking advantage of their vulnerable position, Psylocke ran up to them.

SHULK!

Thrusting upwards, she drove the dagger underneath the clone's jaw, the psionic blade exiting from his cranium. The clone quickly went limp, returning to their original form. Tossing the body, Psylocke continued walking down her hallway.

With Cable, he was dodging punches by Mystique's clone disguised as Domino. Tired of this, Cable used his psychic abilities to hold her still. He then pulled out his plasma rifle, and fired a single charge.

VWOOM!

The charge left a gaping, scolding hot hole in the center of the clone's chest. When she fell over dead and changed back to her original form, Cable went down the hallway. It didn't take him very long to reach the end. Standing at the end of the hall, he noticed it led to a circular room where there was a lift in the center of the room, and three other hallways connected to the room. Psylocke and Domino were in the halls by both of his sides, while Deadpool was in the hallway directly ahead. He and everyone else pulled out their weapons and aimed at each other. He aimed his plasma rifle at Psylocke and a pistol at Domino, the latter aimed both of her pistols at him and Deadpool, the Merc with a Mouth aimed his pistols at her and Psylocke, and Psylocke summoned two psionic daggers with their blades aimed at him and Cable.

"Looks like we got ourselves a classic Mexican standoff," Wisecracked Deadpool.

"You're talking, so, sadly, you may be the real Deadpool," Said Psylocke.

"We also possess our weapons and powers," Added Domino.

"Still, that doesn't confirm we are all not clones. We need a surefire way to confirm we are who we claim to be," Said Cable.

"Hmm, what do you wager?" Asked Deadpool.

"Simple: we all ask each other questions that only we can answer," Answered Cable.

"Very well, shall we go around in a circle like a therapy group?" Asked Deadpool.

"Just start," Said Cable irritatedly.

"Okay. Psylocke, who did you share a psychic bond with?" Asked Deadpool.

"Logan," Answered Psylocke.

"Checks out with me. Seems accurate with the comics," Said Deadpool.

"Your turn, Cable. Why were you first brought into the future?" Asked Psylocke.

"I was brought into the future in hopes of curing the Techno-Organic Virus that has infected my body," Answered Cable.

"That's right," Said Psylocke.

"Domino, what phobia do you have?" Asked Cable.

"Come on, really?" Asked Domino hesitantly.

"Answer the question," Ordered Cable while lightly squeezing the trigger of his pistol.

"Okay, fine! I have alektorophobia; the fear of chickens," Answered Domino reluctantly.

Hearing her answer, Deadpool snickered at her.

"I hope you are a clone, so I can shoot your fuckin' head," Said Domino irritatedly.

"Sorry. Ask your question to me," Said Deadpool.

"According to you, who is your greatest enemy?" Asked Domino.

"... Gavin Hood!" Answered Deadpool angrily.

"And why?" Asked Domino.

"Why? WHY?! Because that fucker picked me up, threw me onto the ground, called me ugly, peed on me, then left me without so much as a 'good day'..." Said Deadpool sadly.

"Translation."

"... He's the director of 'X-Men Origins: Wolverine'."

"Looks like we are all clear, then," Said Psylocke.

Now knowing everyone was who they claimed to be, everyone put their weapons away.

"There's a lift in the middle of the room. Let's take it and see where it goes," Ordered Cable.

Everyone but Deadpool stepped onto the lift. The latter was sitting on the floor depressingly.

"Deadpool, are you coming?" Asked Domino.

"Go on without me. I'll catch up in a moment," Answered Deadpool depressingly.

"Come on, Wade, we don't have time to -"

Before Cable could finish, Domino put up a hoof to silence him.

"Hold on, Cable. Let me deal with him. I've known him long enough to know how to get him moving when he's upset."

Domino walked over to Deadpool, and placed a reassuring hoof on his shoulder.

"Hey, Wade. I know that you don't like talking about him, but we had to make sure it was you," Said Domino.

"Yeah, I know," Replied Deadpool.

"We need to get going, so we can stop Sinister. If you can pull yourself together long enough to help us out, we can stop for ice cream when we get back to Ponyville."

Hearing the word ice cream, Deadpool perked up a little.

"Really?" Questioned Deadpool.

"Mm-hmm," Replied Domino.

"So, I could get a triple scoop chocolate ice cream with strawberry syrup, hot fudge, and chocolate chunks on a waffle cone?" Asked Deadpool.

"Of course. That's your favorite if I recall correctly," Said Domino.

"Let's kick Sinister's ass!"

With a beloved frozen treat as motivation, Deadpool joined up with his friends on the lift. When Domino joined them, Psylocke spoke to her.

"Really? That's all you needed to do?" Questioned Psylocke.

"Wade's like a child. You can bribe him into doing anything if you offer him sweets," Said Domino.

With Cable pressing a button on a panel, the lift began to move downwards. As the lift went down, Deadpool whispered…

"X-Force!"

Passing through the floor, the lift was descending down the side of the cliff. Down below, the group of heroes saw a small army's worth of clones of various mutants. They all stood in an organized fashion, as if they were ready to go to battle. As soon as the lift reached the bottom, and the heroes assumed their battle stances, the entire legion of clones turned to face them.

"So, you have finally come to face me."

Standing towards the back of the army, the infamous Mister Sinister stood mighty and proud like a general. His black colored suit with armored epaulettes and a cape made up of many tassels made him stand out from his legion of clones.

"I'm impressed that you have managed to make it this far. I figured the clones of the mutant Mystique I sent after all of you would have at least slowed you down long enough to deploy the rest of my army," Said Sinister.

"Your clones cannot beat us, Sinister. You might as well come with us quietly now, or else we'll take you by force!" Said Cable.

"Have you looked around, Nathan Summers? You may be an Omega Level mutant, but even you and your acquaintances cannot stand up to the might of an entire army of mutants."

"We'll see about that."

"Enough of this. My subordinates, make them examples of what happens to those who are foolish enough to cross Mister Sinister!"

"Epic fight time!" Cried Deadpool.

The group of heroes ran towards Mister Sinister, with his army heading straight towards them. With weapons drawn, they prepared to fight their way through to Mister Sinister. Shots were fired, blades were swung, and punches were thrown. Many clones fell instantly to the might of the heroes, but many managed to get a chance to fight them. However, even with the numbers against them, the heroes proved their mettle, and matched their might.

Cable used his plasma rifle to gun down many clones before they had a chance to strike him. Any that got too close, he was able to knock back with punches from his bionic arm or knock them out with a psionic blast. Psylocke used a similar tactic to keep opponents at bay. She would use her telekinetic powers to push opponents back, or even towards her in order to stab them with her psionic katana. She would summon a psionic shield to protect herself from oncoming attacks, and toss psionic shields or even create a psionic crossbow to shoot her enemies with psionic arrows.

Domino used her marksman skills to shoot her opponents with deadly, if lucky, shots of her twin pistols. Even though she is a master marksman, that didn't mean she was no slouch when it comes to hoof-to-hoof combat. Any opponent who they themselves were lucky enough to avoid getting shot by Domino, they would be beat down with a few punches or kicks, then finished off with a fatal gunshot wound to the head.

Unlike his friends, Deadpool was less than graceful when it came to fighting. While he was most certainly deadly with a gun and blade, he was not the best when it came down to blocking incoming attacks. He would purposefully let his body get scratched, punched, kicked, burned, and take any form of attack. Despite his reckless and very flawed fighting style, he was proving to be a challenge. Many clones were killed with one shot, and while some were able to throw a direct attack or two, they wouldn't live long enough to do more damage, being sliced up like cheese. Utilizing the Muramasa Blade over his traditional katanas, he was able to cut through clones of mutants that had healing factors without them regenerating.

Over the course of a few minutes, the group of heroes were able to beat a large portion of Mister Sinister's army. Seeing his creations go down without doing much damage in return angered the mad geneticist.

"Useless! I genetically engineered you all to be the pinnacle of mutant and pony evolution! Yet you can't do something so menial as beating three mutants and a wretched mutate!" Said Sinister frustratedly.

"Hey, calling Cable a wretched mutate is a bit much, don't you think?" Asked Deadpool obliviously.

"It seems that if you want to get something done right, you have to do it yourself."

What remained of the clone army stepped aside as their creator levitated towards his adversaries. Psylocke made the first move. With a mighty battle cry, she thrust her psionic katana towards Mister Sinister's chest. He held up his hoof, and the katana stopped mid thrust. With a simple hoof gesture, the katana was tossed aside. The butterfly shaped aura on Psylocke's face appeared, and she attempted to send Sinister flying with her telekinesis. However, raising both of his front hooves, Mister Sinister created his own telekinetic push. His telekinesis proved overwhelming for her, and Psylocke was flung back towards her friends.

Cable shot at Sinister with both his pistol and plasma rifle. The latter erected a force field in front of him, which absorbed all of Cable's shots. Galloping towards him, Cable threw his bionic foreleg towards Sinister. He caught it in his right hoof, and thrashed Cable around like he was a ragdoll. He threw a dazed Cable back towards his friends.

Seeing two of her friends effortlessly beaten, Domino rushed Mister Sinister, guns blazing. He merely summoned another force field to block all of the bullets. Domino threw some punches and kicks towards Sinister, but he blocked all of the attacks with his forelegs. He then used his telekinesis to grab Domino, and grabbed her by the neck. He then looked at her with a wicked grin.

"Where's all of your luck now?" Asked Sinister.

"It's with me!"

Unbeknownst to Mister Sinister, Deadpool sneaked up behind him, and rushed him with the Muramasa Blade.

SHINK!

With a single thrust, Deadpool struck Sinister straight in the chest. While panting, he looked up to see Sinister's face. Instead of seeing a pained expression, he was surprised to see an angered but calm look on his face. He moved the Muramasa Blade around Sinister's chest. Instead of seeing metal cut through flesh, he noticed the blade moved around as if Sinister's body was made of water. Sinister grabbed Deadpool by the neck with his free hoof, and brought him up to his face.

"Bio-molecular metamorphism. Pairs quite nicely with my healing factor to avoid fatal situations. Not even the Muramasa Blade can kill me if it can't cut into my flesh," Said Sinister.

Mister Sinister mercilessly threw both Deadpool and Domino over to where their friends laid. The clone army circled them, leaving them no way to escape.

"Now my servants, kill them!" Ordered Sinister.

The clones rushed towards the heroes, ready to attack. Before they could get their hooves on them, Psylocke got up and summoned a force field around her and the others. Not deterred by the force field, the clones tried to bust their way through. The others got up, taking in all of the clones surrounding them.

"This doesn't look good," Said Deadpool.

"Psylocke, how long can you hold that force field up?" Asked Cable.

"I can hold it for a couple minutes, but after that they will break through," Answered Psylocke.

"We need to come up with a plan and fast," Said Domino.

Deadpool thought about how they could all get out of their current situation. An idea came to him, and he raised his hoof.

"Ms. Domino! I have an idea!" Said Deadpool excitedly.

"Well, go ahead, Wade," Replied Domino.

"It's simple, really. All we need to do is work together."

"What do you mean? We teamed up to face Sinister together."

"Maybe so, but we haven't been working as a team. Think about it, we all may have each other's backs when we need it, but we've been doing our own thing. We need to fight as one unit. Band together like ants. Be a team that is worse than the Avengers but better than the Great Lakes Avengers, Great Lakes Initiative, whatever the fuck they call themselves. We need to be…"

"Dear Celestia," Said Psylocke exasperatedly.

"X-Force!" Said Deadpool while crossing his arms in the shape of an X.

His friends looked at him with blank expressions, so he looked at them with pleading eyes.

"Come on, please? If not permanently, can we be a team just this once in order to save the world?" Asked Deadpool.

Deadpool reached one of his arms towards his friends. For a few seconds, everyone looked at his arm and each other awkwardly. Deadpool was about to lower his arm in defeat when he felt something touch the top of his hoof. He saw Domino had her arm out, her hoof on top of his.

"If all of us except for maybe you, Wade, go out, we might as well go out fighting together, right? What do you two say?" Asked Domino.

Cable looked at her and Deadpool, then placed his bionic hoof in the middle.

"I suppose it wouldn't hurt to team up one last time," Said Cable.

"Well, Psylocke, what do you say?" Asked Domino.

Psylocke looked at her friends, then put one of her hooves in the middle, using her other hoof to hold the force field.

"Fine, let's do it," Said Psylocke.

"Just like old times," Said Deadpool.

From where they all stood, everyone's arms formed the letter X. They then split up, and Deadpool pulled out a bunch of grenades from somewhere. He looked at Psylocke, and she nodded her head in agreement. Everyone stood together very closely, then Psylocke released her force field. As soon as it disappeared and the clones ran towards them, Deadpool pulled the pins and tossed the grenades all around them. Psylocke then formed a smaller force field around them.

KA-BOOM!

A mighty explosion formed all around them, engulfing many clones in fire and debris. As the dust settled, the silhouettes of four ponies could be seen. When it all faded away, Deadpool, Cable, Domino, and Psylocke stood together, ready for battle. Mister Sinister saw this, and he grinded his teeth in anger.

"Seize them!" Ordered Sinister.

(Oh! What song should we imagine in our heads while imaging the fight scene?!)

(How about something from the "Deadpool 2" soundtrack? Let's say "Welcome To The Party".)

Forming a tight circle, the heroes pulled out their weapons, and attacked the remaining clones. Psylocke and Deadpool used their blades to cut through many clone soldiers, while Domino and Cable used their firearms to kill clones with one shot. Eventually, only one clone remained. They tried to run away, it was too late. Cable fired a charge from his plasma rifle, Domino and Deadpool fired a shot from their pistols, and Psylocke fired a psionic arrow. The clone was hit by all four projectiles, and fell forwards, dying instantly.

"Enough of this! I will finish all of you personally!"

Mister Sinister charged towards the heroes. A pulsating light formed in his hooves, and he fired a concussive blast towards the heroes. Psylocke rushed ahead of her friends, and summoned a force field to block the attack. Domino fired a few shots from her pistols, which were blocked by Sinister's own force fields. He heard a klinging sound underneath him, and found a grenade under him.

KA-BOOM!

Mister Sinister was flung back by the explosion. The smoke limited his sense of sight. Just as the smoke faded away, he saw a bionic hoof heading towards his face.

BAM!

Cable punched Mister Sinister straight in the face, causing him to stumble back. Psylocke summoned two psionic daggers, and launched them towards Sinister. The daggers cut through his shoulders, causing him to cry out in agony. He changed his form, so the daggers would fall out, allowing his shoulders to heal. Cable grabbed him by the neck, then flung him towards Deadpool. Deadpool pulled out a grenade, pulled the pin, and attached it to one of the tassels on Sinister's cape.

KA-BOOM!

As soon as Mister Sinister landed on the ground, the grenade exploded. His body was blown to bits, with only his head remaining intact. This didn't kill him, however, as his body was starting to rebuild itself. The X-Force looked down at Sinister, with Deadpool and Domino aiming their guns at his head.

"It's over, Sinister. You have lost," Said Cable grimly.

"Over? This is not the end, my friend. You may have bested me, but you did not beat all of my army. In fact, the rest are being deployed right about now," Said Sinister.

Everyone looked behind them, and saw what Mister Sinister was referring too. Across the sky were entire fleets of zeppelins. They were without a doubt carrying hundreds if not thousands of clones.

"They're going to get away!" Said Domino.

"Time for some duck hunting!"

Deadpool tried his best to shoot as many of the zeppelins out of the sky as possible. Of course, the zeppelins were so high up in the air that not a single bullet had reached them. Psylocke looked at the fleet with a determined look. With the butterfly shaped aura appearing on her face, she directed her telekinetic powers towards the fleet of zeppelins. Many of them stopped in their tracks, but some were continuing to fly away. She tried to concentrate her power to get the rest, but the strain was taxing on her mind.

"Let me help you with that."

Cable stood next to Psylocke, and he reached his hooves towards the zeppelins. To his friends' amazement, he was able to stop the remainder of the fleet with his own telekinesis. Both ponies then directed all of the zeppelins towards each other. All of the zeppelins collided with each other, filling the sky with fiery explosions. As the zeppelins fell towards the ground, they turned back towards their friends.

"That was awesome! You guys just stopped an entire armada of zeppelins with your minds!" Said Deadpool.

"Now that that is over with, let's take care of our friend." Cable and the rest of his friends turned towards where Mister Sinister laid, only to find he wasn't there. "Wait, who was keeping an eye on him?"

Searching for him, the heroes quickly found Mister Sinister, body fully intact, a fair distance away. He looked at all of them with a spiteful look.

"This is not the end, mutants! I will not rest until this world is mine, and genetic perfection has been instilled in all of ponykind! And when I do, you will all be wiped from the face of the planet!"

Before anyone could go apprehend him, Mister Sinister teleported away.

"Fuck! He got away!" Said Deadpool frustratedly.

"Don't worry, he'll be apprehended someday. What matters is that we stopped his plans and saved the world," Assured Cable.

"Yeah. Oh, that reminds me! Domino, I believe you owe me something now that we saved the day," Said Deadpool.

"Oh, right." Looking towards the scattered bodies of the clones they killed, Domino found a small pouch. She picked it up and opened it, revealing some bits. "Nice! Now I don't have to use my money."

"I'll take it that we are all ready to go?" Asked Psylocke.

Everyone nodded in agreement, and Psylocke put a hoof to her forehead.

"Princess Twilight, we are all ready for you to bring us back," Said Psylocke telepathically.

As soon as she notified Twilight, everyone was enveloped in a flash of light. When it faded away, they saw that they returned to the Golden Oak Library. Twilight was in the main library, ready to welcome them back. Before she could, Deadpool grabbed Domino by the hoof, and ran out the door at incomprehensible speed while shouting.

"Be right back! Domino owes me ice cream!"

Everyone in the library looked towards the door. In less than a minute, Deadpool ran back inside with Domino. He held an ice cream cone in his hoof. It was made up of three scoops. The bottom scoop covered in strawberry syrup, the middle scoop covered in hot fudge, and the top scoop containing chocolate chunks. As he happily licked at his treat, Domino looked at him, then the door.

"What the fuck just happened?!" Asked Domino.

"It's best not to ask, Domino," Replied Deadpool.

Twilight looked at the ice cream, giving a knowing look towards Domino.

"You brought up his greatest enemy?" Asked Twilight, even though she already knew the answer.

"Yup," Replied Domino.

"So, I take it that everything went well?" Asked Twilight.

"Yes. Mister Sinister was defeated and we stopped the rest of his army before they could leave Genosha," Answered Cable.

Psylocke had her hoof on her forehead again, but then she put it down.

"I just got confirmation from Charles that all of the clones that were already off of Genosha were defeated. Sinister's army has been truly defeated," Said Psylocke.

"Well then, I guess we should go then," Said Domino.

Hearing this, Deadpool wolfed down his ice cream.

"Before you all go…" Deadpool grabbed all of his friends in a hug. "In case it is awhile before we see each other again, I want to say, thanks for being my friends, guys."

Confused at first, Deadpool's friends reciprocated the hug before letting go.

"Of course, Wade. Thanks for being our friend as well. Oh, and speaking of friends."

Domino grabbed Deadpool by the shoulders, and made him look into her eyes.

"I'm only going to warn you once. If you fuck up your relationship with Twilight and hurt her, I will personally find you and neuter you!" Warned Domino.

"I… Uh, message received," Said Deadpool with a nervous grin visible under his mask.

"Good. Until we meet again."

Domino, Psylocke, and Cable made their way to the front door, with Cable saluting to Twilight and Deadpool. Deadpool looked at Twilight, who looked at him lovingly.

"I see you had a nice time," Said Twilight.

"Of course. There's nothing like meeting up with old friends and going on kickass adventures together," Replied Deadpool.

"I'll admit, I can't decide if I wish I tagged along with all of you, or if I wish I could've gotten myself some ice cream," Said Twilight.

"Is somepony jealous?" Asked Deadpool teasingly.

"Oh, stop!" Said Twilight playfully.

"You're in luck. I got this for you while I was out with Domino."

Deadpool pulled out another ice cream from somewhere. It was a single scoop as opposed to his three, and it was golden white in color.

"Vanilla, my favorite! Thanks, hun!" Said Twilight happily.

"Anything for you, Twi."

Deadpool gave Twilight her ice cream, which she happily grabbed with her magic. As she was about to have her first lick, Deadpool's eyes widened.

"Wait a minute! I know the answer! This chapter's based off of the Deadpool video game! How did I not notice this sooner?! The voices in my head were singing the song when Cable's introduced, Mister Sinister was the main protagonist, we were in Genosha for the large sum of the story…"

As Deadpool rambled on, Twilight could only look at her coltfriend with confusion.

(Now maybe the best time to wrap this chapter up.)

Fin!
