The turtles walked out of the portal to find themselves in a completely white area, with a large computer in the middle. Without talking, Kirby walked up to the computer to switch it on, but before he could Raph grabbed his arm.

Raph: Hey, before ya start typin' away, can you please tell us what the heck is goin' on?! Why where there so many Krangs?!

Kirby: Alright, alright, I'll tell you guys what's happening.

Kirby presses a button on the computer and 2 dozen screens appeared on it, each one depicting the turtles. However, upon closer inspections, each one was either slightly or very different from each other. Some looked exactly like each other. Some looked different. Some looked like they came from a cartoon. Some looked more realistic then others. There was even one where they where frogs of some sort.

Kirby: Ok, this is gonna sound crazy, so stick with me here: you guys know about the Multiverse theory, right? Where there are infinite realities with different outcomes, some small, some big? Well, this computer is showing us only a few of the literal endless possible universes. I'm from one of them.

Donnie: Whoa...this is incredible! I always was fascinated with this theory, but I never actually thought it was real!

Raph: Whoa, slow down big head. You're just gonna believe this guy on the spot? I'm havin' a hard time wrapin' my head around this!

Kirby: Actually, it's pretty easy to get used to it after a while-

Leo: Ok, ok, we get it. This is cool, I'm not gonna lie, but this doesn't explain all the Krangs running around.

Kirby: Oh, that's simple. They come from a universe where there isn't just one evil Krang. There, they're a whole species of nasty aliens named the "Kraang" with two A's. They come from Earth 2012.

Leo: Ok, what're they doing here?

Kirby: That I don't know. I've traveled to a few universes before, but I never seen anyone else do it. My guess is that someone is planning to mess up the Multiverse with some misplacement of characters from other universes. I call them "Crossovers".

The 5th Turtle started typing on his computer and pulled up a list of villains. The main 4 recognized a few: Shredder, Krang, Baxter, Bebop, Rocksteady, etc. But they couldn't name the others on the list.

Kirby: I have a feeling one of these guys are behind this. However, I've gone through all of them, and their either MIA, Dead, or just not good enough to be able to cause all this.

Mikey: Hey, weird idea: What if it's someone we've never fought? You know, a whole new baddie we've never heard of?

Kirby: That's entirely possible. But, for now, we've gotta focus on other things.

He pressed a button on the computer and 4 universes popped up on it.

Kirby: As I was saying, these Crossovers are happening in a handful of other universes. It would've taken me way too long to go through all of them myself, so I decided to get some help from other Turtles. Here's the plan: we each tackle a single universe at once alone. We'll have a communicator I created in case we need to contact each other. We get in there, prevent whatever crossover is happening, then just say the word and I'll beam you back to the base. Any question?

Mikey: (Raises hand) Yeah, uh, if I meet myself from another universe will everything just explode or something? I read that off a comic once.

Kirby: Err...no, I think. The universe is cruel but not THAT cruel. (Presses a button and 4 portals appeared out of no where) Mikey, you'll take Portal 1. Donnie, your 2. Raph, your 3. And Leo is coming with me to 4.

Leo: Gotcha. Everyone else agree?

Donnie: Hey, I don't care where I get sent as long as I can say I've traveled outside time and space!

Mikey: Totally, dude!

Raph: Eh, I've hear some worse plans. Let's freakin' do this.

Leo: Alright Kirby, we've got the plan. Turtles, it's time to save the entire Multiverse!

All four Turtles high five and head through their respective portals, grabbing an earpiece as they left. Leo decided to wait for Kirby before heading out so they wouldn't get separated.

Leo: Hey, quick question: what's your turtle team like on your universe.

Kirby: Funny thing, actually. Where I come from, I was the only Turtle mutated. The others we just sent free. Master Splinter trained me to be the best ninja in the whole planet, and if he succeeded depends on who you ask.

Leo: Wait, you don't have a team? Then how do you fight Shredder or Krang?

Kirby: Well, Shredder is the only real threat where I come from, not counting a few mod bosses here and there. So I didn't really need too much help fighting crime. Problem is, I'm not that good in a team. I'm "Anti-Social" as Splinter puts it.

Leo: Huh. Wait a sec, is that the real reason you had us split up?

Kirby: (Looks surprised, them embarrassed) Uh...honestly, yeah. Sorry.

Leo: It's ok. At least we'll get things done quicker as you said. Trust me, they can handle things themselves.

Kirby: Alright. I'm still sorry. Let's get a move on.

Both of the turtles shake hands and walk through the portal.

(Meanwhile, in some unspecified universe)

LOCATION: WORLD XXXX

HOME OF: UNKNOWN

Inside a seemingly abandoned castle, a figure sat on a throne, looking at a projector screen of Krang and the Kraang army invading New York. He then turns around as we see dozens of other monitors looking over other universes. He snickers softly.

?: Yes...it's all falling into place perfectly. If everything continues to play out as I expect it all to, soon the Multiverse will be thrown into chaos. And I'll emerge from the wreckage, and take it all over. I'll have control over universes before anyone knows it! Hahahahahaa!

Then another voice chimed in.

?: Don't forget our deal. I get one half; you get the other.

?: Yes, yes, don't worry. I'm a man of my word.

With that, the first voice snapped his fingers and a portal appeared in front of him, which spit out Bebop and Rocksteady, along with Shredder.

Shredder: What the...where am I? Who are you?!

Bebop: Hey, did you kidnap us? Don't be lyin' boy, or we'll beat the snot outta you!

Rocksteady: Yeah! What he said 'n stuff!

?: Now now, let's not be hostile. I have a deal for you three...

It then zooms out to show the rest of this universe, where it seems everything is in ruins. Buildings are destroyed, the streets are empty and dirty, and the only sign of life are a few bugs. The worst part, however, is four multi-colored bandanas laying on the floor, tattered. This is a universe where the Turtles have died.
