"Let me break it down for you," Deadpool explained as he started drawing on the whiteboard.

"I've never seen Deadpool- or at least, my Deadpool- to be so…"

"Serious?"

"Focussed. I was going to say focussed." Mewtwo replied to Piper.

"Most people tend to think of time as like a river," Deadpool went on, "Each time something different happens, the river branches out. But now let's say that time is more like several streams all parallel to each other." Wade said as he flipped the whiteboard to start a new example.

Mewtwo's eye was wandering around the large 'common room' of the base for a bit while Deadpool fumbled with his marker. He saw that a lot of them were sporting casts, and bandages. Without a steady supply of Senzu Beans or any other healing technology, the phantom pains and lasting injuries were quite a nuisance. Those with healing factors like Nova or healing magic like Yuna were tasked with keeping others alive until the were brought back up to full with what little they had.

"Time is hard to alter without damaging the other rivers." Wade's explanation brought Mewtwo out of his thoughts, "Imagine trying to alter the flow of one river, without breaking one of the others."

Despite his intellect, Mewtwo couldn't think of one outside of building a dam.

"Sure, you can make a dam, but that would cause some of the water to spillover into the other rivers. If time can't move in one line, it'll move in another."

"Question!"

"Yeah, Mew?" Deadpool asked, irritated by the interruption.

"Isn't there an easier way for you to describe this to make it easier to understand?"

Deadpool sighed. "Fine. I had a really elaborate explanation for this, but whatever."

"Just simplify it." Mewtwo offered.

"Okay, this universe, we will call 'Universe 1.' The one that is technically the original will be 'Universe A' - "

"'Universe A'?"

"That way we don't cause a crazier version of us to try and kill us for giving them a lesser universe designation." Deadpool waved off. "Back to business, something happened in Universe A that caused this to happen. As for what, we don't know, but it came after Vegeta's fight with Shadow."

"How so?"

"That was around the time that one of the hosts' computers crashed and lost all of the data on everything after that fight." Mega Man X said, interjecting into the conversation.

"But, how would something that happened in this universe cause something to happen in another universe?"

"Weren't you paying attention?" Piper asked, "He just said that if something big happens in one universe, then that could affect the other universes as well."

"If there was an explosion, the resulting blast could have caused a ripple effect that would make it so that things earlier in time would be affected." Deadpool mused.

"Can someone explain this to me in simpler terms? I'm not Dialga or Celebi here."

"Look, as soon as we can figure out what went wrong in this timeline, we'll have a plan of how to fix it." Deadpool explained, "Until then, get yourself reacquainted with the others."

"I was never acquainted to begin with."

"You you, maybe. But other you was friends with a lot of these guys. Best to familiarize yourself with them."

"May as well."

"And leave your comms device here. Maybe the data from that can help us figure out what happened."

"Uughh…"

As anyone could tell you, war was an absolute hellish nightmare that nobody should have to go through.

Medics were being stretched thin. Anyone who could fight, was on patrol to get supplies. All who could help heal others, were exhausted.

Vegeta, the prince of all Saiyans, was getting debris that had lodged themselves inside removed by Kitty Pryde.

Guts was getting his arm set into a cast by a guy in a wingsuit -Falcon. That was his name.

Mewtwo also looked around and saw Optimus Prime receiving repairs from Iron Man and Zero.

"I have to go help with Prime's repairs." X said, walking off to lend a hand with the Autobot.

Suffering. Everywhere was suffering.

"How are you feeling, big guy?"

Optimus did the Cybertronian equivalent of a sigh, "Without the Matrix, all hope is lost."

Tony sighed, "Again with the Matrix being lost along with all hope. Y'know what Cap would do if he lost his shield? - He'd keep fighting. Even if his opponent was using it."

"What are they talking about?" Mewtwo turned to a guy in armor who looked like Carolina… Tucker. That was his name.

"Prime lost his Matrix of whatever, and he went all pessimistic. Dude is such a downer." Tucker groaned, "At least he's not as much as a whiny little scrawny blond kid I had to fight."

"I can imagine. Back in my timeline, Yang would tell stories of how she would mess with him by encouraging his idiotic masculine behavior."

"Heh, I can imagine." Tucker chuckled, "I mean, I back down when a chick says 'no.' that dude thinks it means 'try again later.'"

"I can imagine what stupid thing he'd do to tick people off though."

"Wow. This Mewtwo is lucky. Mario vs. Sonic was fight thirteen, they had Peach fight Zelda, and there was even two fights where Goku fought Superman."

Pinkie took a look at the monitor, "Hmm, Cloud won't be happy when he finds out that Batman couldn't beat Spider-Man."

"We all know how much of a Bat-fan he is." Deadpool remarked.

"Huh. They had Fulgore fight Sektor? - Why?"

"Should've been Cyrax." Wade replied, "Elder Gods rest his soul."

"They had you fight Deathstroke before fighting me?" Pinkie asked, "Your healing factor makes you broken for this scenario."

"Yeah well-" Something caught Wade's attention, "That's weird."

"What's up?"

"There's a footnote under… Toph vs. Gaara?"

"Well, scroll down. Let's figure it out…"

Right there. In front of them, was a few simple words.

Rematch yields opposite result.

"They caved."

"Well," Wade trailed off, "At least we know what the hell happened."

"Now we just have to figure out what happened after it."

"Let's get everyone in here."

"So, have we figured out what happened?"

"Yep. Apparently, there was a rematch in Universe A caused a split in the timeline. What we need to do, is to get into that universe, and stop that rematch from happening."

"How are we going to do that?" Mewtwo asked.

"You ever see Justice League: Flashpoint Paradox?"

"No."

Deadpool faltered a bit at finding out that Mewtwo hadn't seen one of DC animated productions' best films, and went to recover.

"Days of Future Past?"

"No."

"Back to the Future?"

"No."

"Terminator: Genisys?"

"No."

"Meet the Robinsons?"

"No."

Deadpool had all but given up. But… there was one movie that he didn't mention yet…

Deadpool sighed, pinched the bridge of his nose, and said, "Hot Tub Time Machine?"

"Oh yeah."

"Goddammit."

"What's wrong with Hot Tub Time Machine?"

"Nothing, it's just a stupid movie." Wade replied, "Back to business, we have to correct the timestream before we lose the city. It's the only line of defense against the chaos out there," Wade gestured to the window, "And the rest of the net."

"Great." Mewtwo sarcastically replied, "No pressure or anything."

"We -uurp- modified Lavender-Head's time machine and my portal gun to basically let Shadowcat here send you to another dimension and time."

Kitty nodded, "Yep. All we need are a few more supplies and we'll have everything up and running."

Mewtwo nodded.

"What do we need?"

"Like any video game, we need three items." Silver replied, "That's the good news."

"I take it that there will be bad news as well." Mewtwo observed.

"It shouldn't take a psychic to know that." Rick Sanchez pointed out, "One of the items that we need is in sector 18-75. Which, as we all know, is-"

"Doomsday's territory." Deadpool finished, "What do we need from there?"

"Lex's suit had a specialized power source that can help make sure that we can generate enough power without having to divert energy from the outer shields or our floatation device." Shadowcat answered.

"Alright." Deadpool nodded, "What are the other things?"

"There's an artifact in Aku's palace. We get that, we can get a better fix on the timeline that we're aiming for."

"So, send in some of our ninjas for that one. And the last thing?"

"Braintron's ship." Silver mentioned, "The time machine that Mewtwo came back on has a certain temporal energy signature. We think Braintron is trying to use the tech to repair his ship. If he pulls that off, he can get here, and fight us. Floating base to warship."

"So, we should send some of our stronger teleporters there to get it out as soon as possible." Pinkie concluded, "I guess that we have our regulars getting supplies and using guerrilla tactics to keep the mooks disorganized?" Deadpool nodded at her question.

"Alright. We have our objectives, let's try and get those items."

Meanwhile, in an unknown location…

"Hmm, so the fools really think they can stop my plan? Ha ha ha… Well, let's see what a bit of dark magic has to say about that…"

Piper was with Shadow, Silver, Zero, Goten, young Trunks, and Danny Phantom. Her team were assigned to get the power device from Lex's suit

"Okay, we all know the plan?"

Shadow rolled his eyes, "Yes we know the plan. This isn't some television show where we need to explain the plan to everyone so that the audience knows what's going on."

"I never really got that," Zero replied, "I mean, from a storytelling standpoint it helps to inform the audience, but from the perspective of the characters, it makes no sense. They should know what the plan is, but it's just explained as if nobody was paying attention."

"Are we sure? Because we can go over it to make sure everyone's on-board." Piper offered.

"Pretty sure." Danny said, "I mean, it's a simple plan. We don't need to go over it."

"Alright then." Piper shrugged, "Just checking to make sure that everyone was paying attention."

.

.

.

"Uh, we actually weren't paying attention." Trunks said.

"The moment you opened your mouth, I knew we were going to have to explain it." Shadow sighed.

"The plan is simple," Zero said, "We go in, we grab the power generator, and we get out before Doomsday can get to us."

"And if he does try to get to us, we have a guy who can turn intangible, two guys who can stop time, and my last Oblivion Crystal to hold him off." Piper added.

"Okay. Seems simple enough."

Silver grumbled, "Well, plans never survive first encounters with the enemy."

Hanzo, Kuai Liang, Sakura, Black Cat, Catwoman, and Mai Shiranui were sneaking around Aku's palace.

"We all know what we're looking for, right?" Sub-Zero asked in a hushed tone.

Catwoman nodded, "We need some kind of amulet to grab, and get the hell out of here before that so-called 'master of darkness' notices anything."

"I'm channeling my probability manipulation to everyone that isn't us." Felicia mentioned, "It would take a lot of skill on their part to find us."

"Considering they're mindless drones, I'd say we should be good." Mai mentioned.

"Hold on." Hanzo motioned them to quiet down as they saw a few drones pass by.

Among them was a girl. One that some of them have become rather acquainted with. Her veins being shrouded in black. Her head turned in a way that sounded like it was an exposed muscle being released from a rigor mortis.

The drones stopped, and looked towards her.

She waved them down with her hollow and broken eyes, "It was nothing." She said in a hoarse tone, "Keep moving."

The drones and girl passed. Letting the current ninjas breathe a small sigh of relief.

"Let's just grab the thing and get out." Selena grumbled, "This place gives me the creeps. And I've been to both of Batman's caves."

"I thought he only had one cave?" Mai asked, "What are you- oh…" She shuddered at the thought while Selina smirked.

*BAMF!*

Nightcrawler, Tucker, Falcon, Iron Man, and Raven all appeared on Braintron's ship. Those not holding onto Kurt were transported by Raven's magic.

"Quick! Hide!"

Nightcrawler jumped to the ceiling, while Raven shrouded the others in her magical shadows.

The others waited for the drones to pass before trekking the next item on their list.

"Damn, we should have gotten Black Cat or Catwoman here to help out." Tucker grumbled.

"So you can flirt with them, or so that they could snatch that thing that we need?" Falcon quipped.

"Bit of both, really. I heard that they were up to a threesome."

"Foursome, actually." Surfer corrected, "Black Cat wants Spider-Man in on the whole thing."

"What does that kid have that I don't?" Iron Man grumbled.

"The ability to hold a non-destructive job?" Raven offered.

"Being able to surpass chemists while in high school?" Falcon asked.

"Crazy things that can be done with those webs?"

Tucker looked around, "What? - I can't have weird thoughts from time to time? - I bagged Grif's sister and had an alien baby." He took out a picture of his son's high school basketball team, "I'm winning this. That way he won't have to worry about dealing with the bullshit that goes on in this damn world."

"You'll see him soon enough." Surfer comforted, "But for now, we need to ensure that this world doesn't share the same fate as any other. And to do that, we need to keep Braintron from getting his ship into the air."

"Right." Tucker sighed, "Let's get going."

X: Indeed, let's. Right guys?

X as Wade: Hoo! Wee! Aren't you a load of crap?

X as Pinkie: That's unnecessarily mean, Wade!

X as Wade: Don't care. I'm Deadpool!

X: Ahh… It's good to be among people you care about. Right Alexis?

X as Alexis: Tweet chirp tweet!
