Chapter 5-The Practice Room

"So, you two are inventors?", Dipper asked as the Flynn-Fletcher brothers were busy setting up in their room.

"I guess you could call us that!", Phineas replied, taking out a notebook from his bag, "We're also adventurers, treasure-hunters, singers, writers, I think we should probably just stop there."

"Geez, they're like tiny college students", Mabel whispered.

From behind her, the green-haired scientist known as Ferb accidentally bumped her from behind, tripping to the ground.

"Oh, I'm sorry!", Mabel apologized, "Are you okay?"

Ferb slowly got up and nearly gasped. His eyes widened once he looked at Mabel. Time slowed down as the background changed to a shiny pink. Hearts danced around around the young girl as Ferb's eyes grew wider. His heart raced as Lionel Richie's "Hello" played in the background.

"Umm, is he okay?", Mabel said as everyone stared at Ferb's awkward, silent gazing.

"Don't worry, he's fine...for Ferb", Phineas answered before helping his brother up. Mabel looked at Dipper and shrugged.

….

The gem-human hybrid was setting up his bed as he was sleeping right next to the warriors of Ooo. He quickly changed into his pajamas as Finn and Jake walked into the room.

Steven smiled, "I still can't believe that this is happening! Other earths!"

"Heh, this ain't my first time on another world, dude", Finn chuckled, "I mean, we've been to the Nightosphere, the Land of the Dead,...Mars!"

He stopped talking once he noticed the boy's childlike, starry gaze.

"M...M-M..Mars?", the boy squeaked.

"Oh yeah, dude!", Jake exclaimed, "It was cool! I mean, we nearly died, but it was cool!"

"Dude, I've only ever been to one world!", Steven squealed, "And I nearly died too!"

"SWEETCICLES!", Finn yelled, before he and Jake jumped onto the bed, their heads in their hands gazing with interest.

"What was it like?!", Finn asked.

"Were there people?!", Jake asked.

"Were there lazers?!" Finn asked.

"How did they try to kill you?!", the two asked gleefully.

Steven laughed, happy to discuss this with the two. He was happy to be able to relate to another human who's been through the same stuff that he did. He had Connie, his dad, and the others but they didn't completely understand it. These guys did.

Finn was happy to actually talk to another human being. He's seen very few of them on his world since they're endangered and those that he did talk to weren't exactly the best. It was cool to talk to another human who was raised in similar circumstances as him.

As they talked, they failed to notice the scientist staring through the door, analyzing the two. He shrugged and walked off indifferently. He entered his elevator as he went down a few floors to a dark room. He flicked a few light switches as energy buzzed through the room, lights switching on.

It was a large laboratory, chemicals of all colors and tubes of all shapes and sizes everywhere. Bright, blue screens suddenly turned on as the man took a seat in front of the biggest screen. He began typing, editing documents regarding the recruits.

As he typed, a small message popped up at the bottom right side of the screen. He looked over to see the message, thinking that it was from his superiors. Unfortunately, it wasn't.

"Idiot:

Hey, Dex! Where've u been? How r u?"

Dexter rolled his eyes and quickly closed out the message, ignoring it. He continued to type until he heard something behind him.

"You know, it would be nice for her to know where you are."

Dexter growled, "Miss Possible, I could not care less about being nice for her."

"Really?", Kim asked, "Dude, we all saw the way you were staring at the recruits. The Pines twins. The inventor brothers. The dog and the boy."

"Your point being?", Dexter asked.

"You want what they want!", Kim pointed out, "A family! Someone who actually cares for you!"

"HA!", Dexter scoffed, "I can't believe this. Have you met my family? They are all so...so...idiotic! No no! I prefer to be alone."

"Well, that's fine. I don't care how lonely you are, dude", Kim rolled her eyes, "But don't force your little loner agenda on the others. They're perfectly happy with each other!"

"I am not spreading any agenda!", Dexter argued, "I'm simply telling them to listen to my beliefs and split up with one each other to truly be able to follow their goals!"

Kim glared at him, realizing that she wasn't gonna be able to get through to this guy, "Whatever. I'm out."

Before she exited the room, Dexter suddenly said, "He wouldn't have made it….He wouldn't have lasted a day here."

Kim quickly turned around and snarled, "DON'T act like you knew what he was capable of! Don't act like you understand!"

"Whatever, woman", Dexter responded, going back to typing. Kim glared at him and slowly walked away.

The scientist suddenly stopped typing and looked down at the keyboard. He dragged his mouse across the screen and pulled something up on his laptop.

On the screen were now several messages. All of them from his family. Asking him where he was. Asking him how he's been doing, when he's coming back.

Telling him that they missed him.

He sighed, taking off his glasses, as he, once again, closed the messageboard and went back to work.

...

The recruits walked into an enormous room, having been called in by Dexter and Agent Possible. It was a large, silver room with nothing in it. Just reflective metal everywhere.

"Are they here?", Dipper asked.

"I don't see them", Jake said, "Ya' think they ditched?"

"Oh no, we are here, Mr. The Dog."

The voice rang out suddenly, surprising the recruits. They scanned the room but saw nobody there.

Marco jumped in surprise, "OH MY GOD, TELEPATHS!"

"Dude, that's ridiculous", Dipper said, "It's obviously ghosts! Duh!"

"Actually, it is neither, you freaking morons", the voice rang out again, the group realizing that it was Dexter's voice, "I am speaking through the loudspeaker and can see you through the security cameras."

"Cameras?", Phineas asked, looking at his brother, "Called it. They always have those."

"You are now in what I call the 'Practice Room'", Dexter announced, "This is where you and your group will practice and prepare to fight. Your main goal is to survive."

"Uh, excuse me? Do we at least get some weapons?!", Dipper shouted at the ceiling. He turned to see his teammates pull out weapons of their own. Finn whipped out a sword, Jake began to shapeshift his hand into a mace, Mabel pulled out her grappling hook, Star pulled out her wand, Marco got his nunchucks out, and the inventors pulled out some random laser guns. Even Steven had a weapon, as a beam of light projected from his stomach. Out of nowhere, a pink shield was formed with an arrow embellished on it.

Dipper's jaw dropped, "...DO I AT LEAST GET A WEAPON?!"

"First lesson of fighting for C.L.U.B.", Dexter said, "Always have a weapon on you. Now, duck."

"Duck?", Dipper raised his eyebrows.

*FWOOOM!*

Out of nowhere, a stream of bright, red fire shot out from the wall, causing the boy to jump to ground. The other recruits screamed as suddenly, fire burst from the sides of the walls. Steven was able to create a bubble around himself, accidentally, entrapping Mabel and Star and pushing Marco and Finn into the streams of fire.

Marco and Finn screamed in pain while Mabel and Star fired their weapons mid-entrapment, causing their weapons to ricochet off of the bubble and knock them down.

"SORRY!", Steven apologized, accidently dropping his bubble and nearly being hit by the fire.

Dipper cried in fear as Jake quickly stretched himself around the fire and grabbed Finn and Marco, trying to put the fires on their clothes out by beating them around on the ground.

"OW! OW! OW! NOT! HELPING! OW!", Marco shouted repeatedly.

Phineas and Ferb were able to change their ammo to fire balls of water at the fire, though it didn't help much.

"Well, this is failing", Ferb bluntly stated.

"Not helping, Ferb", his brother stated.

The fires turned off quickly as the recruits fell to the ground, tired.

"Okay, this round is now over, ladies and gentlemen", Dexter said over the loudspeaker.

"Oh, thank God, it's over!", Marco groaned, rolling around on the ground in pain.

"Now onto round two!", Dexter quickly added.

"...Whu?", Finn squeaked.

Suddenly, spinning spiral blades appeared, rolling around the room and towards the recruits. Sparks flew everywhere as they tried to dodge each and every saw coming towards them.

Finn yelled as he tried hopping over the blades coming at him until he ended up having to balance himself on top of one of the blades, which was still rolling across the room.

"HAAAAAALP!", he screamed as he had to run across the blade to prevent himself from falling off.

Steven threw his shield at one of the saws only for it to knock one of the saws off of the ceiling and begin to roll towards him uncontrollably.

"HOLY-!", Steven was interrupted once the saw was launched right above his head, nearly taking his head off.

"Don't you have any magical powers or anything?!", Jake yelled at Star.

"Hang on! Thinking of something right now!", she yelled as she jumped onto Jake's shoulder, pointing the wand at the saws.

"SHIMMERING DESTRUCTO CANNON!", she screamed. Her wand quickly began to glow up and suddenly, it transformed into a giant bazooka-like weapon. She aimed it at the blades as missiles began to fly everywhere. Some managed to hit their targets but most of them flew right back at her, literally exploding right in her and Jake's faces.

Dipper quickly launched himself onto Mabel as he quickly took the grappling hook from her hand and fired it at the ceiling, pulling the two up as the saws sliced everything around them.

After a few minutes, the round ended, as the group reassembled at the middle of the room. Each one of them had a cut, burn, or bruise and were extremely tired.

"This is awful", Dipper groaned.

"This is awesome", Phineas grinned, without a scratch on him or his brother.

"HOW ARE YOU oKAY?!", Steven shouted.

"Oh, Ferb held me up while we both used our guns to redirect the paths of the saws!', Phineas explained, Ferb nodding behind him.

"Teachable moment, everyone!",The group looked up to hear Agent Possible on the loudspeaker, "If you're gonna do this, you need to work together as a single unit! You need to work alongside each other and use your individual skills to solve these issues!"

"She's right, guys", Steven agreed, "Try to work with someone who you haven't met before yesterday! Try new ideas and work at a different angle, people! If we mix up our strategies, we can do this!"

Muttering was heard as the teammates talked with one another. They weren't fully comfortable with working with someone outside of their own partners and didn't know what each other's main forms of attack were. However, they realized that they didn't have much of a choice and began to team up with other teammates.

"Okay, guys! This is just another round and it is hopefully over!", Star smiled, "Piece of cake!"

Suddenly, not only were the buzzsaws reactivated, once again spinning everywhere, but the streams of fire were once again activated, blasting everywhere. Everyone screamed as they began running around with no strategy.

"EVERY MAN FOR THEMSELVES!", Star screamed, quickly pushing the others out of the way as she tried to survive. She grabbed onto Marco and began to carry him to safety.

"MABEL! STAY DOWN!", Dipper yelled, pulling his sister to the ground. Suddenly, a buzzsaw came towards them, "NEVERMIND! STAY UP! STAY UP!"

They jumped up, only for another blast of fire to nearly scorch them.

"NEVERMIND! STAY DOWN! STAY-!"

"WE'RE ALL GONNA DIE A SLICED UP AND ROASTED DEATH!", Mabel screamed, "WE'RE AT DEFCON THANKSGIVING DINNER, DIPPER!"

Jake tried knocking down the doors to escape but it was no use. They were stuck in there!

Steven began shouting at everyone, "GUYS! GUYS! WE HAVE TO WORK TOGETHER ON THIS ONE! WE HAVE TO...stick...together."

Phineas and Ferb slowly walked up to him amidst the chaos.

"Hey, room for two more in the bubble?", Phineas kindly asked.

"Oh, sure!", Steven smiled as he create a pink bubble around them.

"Whoooa! Far out!", Phineas smiled, "Okay, if we're gonna do stop this, you need roll this bubble over to the flamethrowers and let the fire hit the bubble!"

"WHAT?! BUT WHAT IF-?!", Steven shouted, alarmed by the request.

"Trust me! I think I have an idea!", Phineas assured the boy.

Scared, Steven quickly pushed the bubble over to one of the streams of fire. By blocking off its path, the fire was reflected off of the bubble and began to burn one of the saws, causing it to pop off of its track and fly around. The saw began to ricochet off of the walls and crash into other saws, which eventually all burned down due to the now-destroyed flame throwers. The three sighed in relief as the bubble dissipated around them.

The doors of room opened as Agents Dexter and Possible entered.

"Okay, everyone. How had the test gone?", Dexter asked before looking up from his notepad.

All of the recruits were injured, lying on the ground in pain. Scratches and burns were all over their bodies as they rolled around in a tired manner, groaning. Only Steven, Phineas, and Ferb weren't injured. Everyone picked themselves off of the floor and began to walk past Dexter and Kim.

"I think my heart stopped for, like, a minute", Finn muttered.

"What are the symptoms for internal bleeding", Marco worriedly asked Star.

Only the agents, the Pines twins, the Flynn-Fletcher bros, and the gem were left in the room.

"What was that?!", Dexter asked, "The goal of this was so that you could all work in unison with one another! Was that so hard?!"

"Dude, we didn't know what to expect here!", Mabel argued.

"THAT'S THE POINT! You need to be prepared for what you don't expect! That way, you can easily work together to solve any issue!", Dexter screamed.

"He's right, you guys", Phineas added, "We need to find a way to get to know each other's strategies and forms of attack! Maybe we could have a get-together or something. Hang out."

"Yeah, that could work!", Steven agreed.

Dexter pinched the bridge of his nose in anger, "Sure, whatever. Just get yourselves together! We cannot defeat the enemy like this!"

He proceeded to walk off as Kim walked up to the group.

"Geez, someone has a case of the grump-grumps", Mabel frowned.

"What is with that guy?", Dipper asked.

"No idea ", Kim said, "But he is right. You guys do need to be able to work together if you're gonna pull this mission off."

She began to walk off, Steven and the inventors following her.

"So, we're gonna need to find a way to get everyone together and just...talk", Dipper repeated, trying to come up with ideas.

"My time has come!", Mabel suddenly cheered, "Come on, Dipper! We've got work to do!"

She quickly ran off, leaving Dipper in the middle of the hallway.

He sighed, thinking about what happened over there. What was he doing here? He literally did nothing over there! He didn't have any powers or any special weaponry! He was...useless.

The boy tried to push away those thoughts and walked back to his room, wondering if this would all go well.

...

At the med bay, Phineas and Ferb were working with the other doctors to help treat the recruits who got injured in the practice room.

"This is such garbage", Marco growled, "I'm starting to think that these guys actually want us dead!"

"Don't worry, man", Phineas smiled, "This was just practice. We'll probably do better next time!"

"How are you so positive about this?", the red-hooded boy asked, "We couldn't handle a simulation! How do you think we'll be fine in a real problem!"

"Well, for one thing, we ARE the 'greatest heroes in the multiverse' and two, you can't just let one failure take you down! You know what I mean?"

Marco turned around and looked at Star, who he could tell was hearing this, "Yeah, I know."

Star was on the verge of tears. She was having trouble taking that inventor's advice not only because of her failure to save Glossaryck, but because of her constant failures to save the world without something else either getting in the way or someone else having to help her out. She just...she didn't want this to fail either.

Finn screamed, "AAAARRRGGHH! I can't take this anymore! Green bro, do you guys have anything?! Magic potion? Cyclops tears?"

Ferb shrugged as he continued to patch up the boy's leg, Jake helping him.

"Dude, calm down, okay", Marco said.

"I CAN'T CALM DOWN!", Finn shouted, "I need to get un-hurt right now! Can't let my body fail me now!"

"It's just a few cuts, man", Marco glared, beginning to get annoyed by the warrior's childish tantrum.

"You know, cuts do make guys look cooler!", Star said, trying to find a way to calm the man down.

Finn stopped and looked over at Star, "R-Really?"

"Oh yeah, totally, dude!", Star assured, "I knew a few of the guards back on Mewni, total coolios, those dudes!"

"Whoa! What were they like?", Finn asked, "Were they, like, buff and junk?"

The two began to chat it up as Marco blushed, frowning at the boy. He didn't know why but something about the two talking...infuriated him.

...

"Yo, Dexter?! You in here?!", Kim yelled as she entered the laboratory, looking for the red-headed scientist. What was actually there was what surprised her.

In the middle of the room was a giant, purple portal, swirling around the middle of the room. The agent quickly pulled out her weapon and began looking around, making sure that this wasn't an enemy portal.

"Dexter?!", she screamed out, "DEXTER?!"

….

Another Earth. Another Time.

The man darted through the trees as the sounds of his enemies catching up with him could be heard right behind him. He quickly jumped up onto one of the branches and ran across the canopy to escape, not in the mood to fight.

However, this didn't stop anything as his enemies quickly caught up with them, firing lasers from behind.

They were round, with long legs and laser guns for arms. Their metallic, warrior-themed heads glistened in the afternoon sun as they prepared for combat.

The man didn't even bother to pull out a weapon.

He quickly back flipped behind them and tackled one of the robots from behind, quickly kicking him at another bot right next to him. As their pieces flew everywhere, the man quickly snatched up one of them and used it as a shield against his opponent, causing the laser rays to fly back and hit the assassin.

Hearing others trying to follow him, he quickly darted off into the jungle, hiding behind a fallen tree. They passed right by him and went the wrong direction.

The man slowly got up, brushing off grass from his blood-stained white outfit. He scoped the area and began to walk off, trying to come up with an idea as to what he should do.

"You know, you should probably fix up that wound."

In literally a second, the man launched himself at the one who spoke, his head looking over the stranger's shoulder and a long, silver sword gleaming under the stranger's neck.

"Easy, buddy", the agent spoke up, "It's just me."

The man looked at him and realized his mistake. He slowly backed away, sheathing his katana but still keeping his usual stern glare.

"Mister Dexter", the man said in a deep voice, "My humblest apologies. I did not expect to see you here. Is this about the deal?", the man asked, "Have you finally fulfilled your promise?"

"No, I'm sorry", the scientist apologized, "I've tried everything but..."

What little hope was in the man's eyes slowly faded, "Ah...I understand. Then, why have you come?"

"We need your help", Dexter answered, "Everyone needs your help."

You can probably guess who Dexter is talking to.

So, we're seeing the recruits begin to interact with one another and each interaction is different. Because of their different fighting styles and their different interactions, it's going to be difficult for them to cooperate with one another.

Steven gets along with Phineas and Ferb, seeing as how they're the most innocent of the group. Finn and Jake become friends with Steven and Star since they're the weirdest of the group. Marco and Dipper, being one of the few sane guys in the group, are slightly annoyed by Finn, and Dexter basically hates everyone.

And yes, I just made a joke about Ferb having a crush on Mabel (try not to look to deep into that one).
