It all starts in the Turtles' home, where the Turtles are having some down time doing some various activities. Leonardo, who is shining up his swords to keep them clean. Donatello is studying while watching the science channel about outer space. Michelangelo is rollerskating around the place. Raphael started lifting weights. And Master Splinter is meditating in a nearby room. All of a sudden, the news channel was on.
News Reporter: This is Channel 6 News! We go live with April O'Neil!
April is outside in the city where the situation happens.
April: Good afternoon! There has been a crisis going on around here in the city where people are vanishing into thin air and some who are still around for the series of events when an alien attack took place a few days ago at the Greenwhich Village where two aliens started to cause trouble until Iron Man a.k.a Tony Stark battled the creatures until Spider-Man came along. But they manage to sneak on board the donut ship where Doctor Stephen Strange was abducted. Mostly they were in outer space. But where are the rest of the Avengers?
And she disintegrates as the Turtles look on in horror.
Turtles: NOOO!
News Reporter: It looks like some our workers are disappearing in thin air. But it looks like there's only one way to help stop this madness! Call in the Teenage Mutant Ninja Turtles!
And then he disintegrates.
TV turns off.
Mikey: What's going on out there?
Raph: They're starting to go away into nothingness.
Leo: Well we're inform Master Splinter about the situation between the unknown threat has caused all of this.
Don: I don't know about this, Leo! But we're gonna go figure this out on our own until we get to the bottom of it.
Master Splinter: My sons!
He starts to disintegrate.
Turtles: NOOOO!
Don: Master Splinter!
Raph: Not him too! What else is going to happen next?!
Mikey: Well we're going to find the Avengers! They can help put a stop to it!
Leo: Mikey, they went to Wakanda to inform T'Challa about the alien threat that is going to destroy the universe.
Mikey: Oh, right! It looks like we're on our own!
Don: We need to find Casey and discover what's going on!
Raph: All right! Let's move!
They head off to the streets only to discover civilians turning into dust and some who are not.
Leo: This doesn't look good! We saw Master Splinter vanish and now this!
Mikey: Look, it's Casey!
Casey arrives.
Casey: Guys did you just see what's going on?
Don: Yes we did see it. We saw April turn to dust.
Raph: And Splinter's gone too!
Casey: Guys! We might as well find the Avengers! They'll know what to do!
Mikey: They're in Wakanda!
Casey: What is Wakanda anyway?
Don: It's country that is hidden from society to avoid outsiders about their mysterious material called Vibranium.
Casey: I never heard of it before.
He suddenly begins to disintegrate.
Casey: Oh, no! Guys whatever you do: Inform the Avengers about the series of threats.
Leo: We're on it, Casey!
Casey nodded before he disappears.
Mikey: Now let's go find them.
Leo, Raph, and Don: All right!
They head off to the New Avengers Facility.
