(The Injustice/RWBY/Overwatch heroes and villians all emerge in the Fortress of Solitude... or what used to be the Fortress of Solitude. The merger of universes has left it as a floating cosmos of minature asteroids, which somewhat resemble the crystal rock of the Fortress of Solitude.)

Glynda: Great Oum!

Batman: Something is definitely wrong here.

Roman: I like it!

Ironwood: You would.

(Lie Ren holds his head in agony.)

Supergirl: This is what's in store for Earth if we don't stop Shinnokal-El. Grinding two universes together will eventually rip them both apart.

(Doomfist points to an asteroid above them, where the My Hero Academia/Mortal Kombat/Avatar: The Last Airbender forces have portalled in.)

Doomfist: A portal! Dark Kahn must know we're here! He sent his forces to stop us.

Coco: Fine with me! Let's take 'em out!

Reaper: Wait. They may not be aligned with Shinnokal-El.

(The rage passes to D.Va.)

D.Va: Who cares? They tried to kill me!

Batman: Let me talk to them.

(On that asteroid, the My Hero Academia/Mortal Kombat/Avatar: The Last Airbender forces portal in. They are confronted by a vista that vaguely resembles the floating void of Outworld, but it's interconnecting asteroids look like they're from another universe.)

Shang Tsung: What happened?

Baraka: This is Outworld?

Kitana: It is worse than when I left.

Raiden: This is what will become of the realms if we do not stop Dark Kahn.

(Kano points to a nearby asteroid.)

Kano: Over there! Dark Kahn's forces!

(They see the Injustice/RWBY/Overwatch Universe forces. Superman steps forward.)

Tarantula: Their commander approaches. I will speak with him, but be ready to fight.

(Tarantula teleports onto the asteroid with the Injustice/RWBY/Overwatch forces.)

Batman: I am Batman. We need to know your intentions.

Tarantula: I am Tarantula, Shirai Ryu Firebender. With me are the mightiest warriors in all the realms.

(The My Hero Academia/Mortal Kombat/Avatar: The Last Airbender forces jump from their asteroid next to Raiden.)

Tarantula: We have come to challenge you in Mortal Kombat. You will be defeated.

Batman: Don't be so sure, Tarantula. If you want a fight you'll find my friends and I are up to the challenge.

(As everyone prepares to fight, Lie Ren and Liu Kang grab their heads in pain.)

Glynda: Ren, what's wrong?

Kitana: Liu Kang, what's wrong?

Lie Ren: Out there...in the distance...I can feel it!

Liu Kang: I can sense something...something big...it's here!

(Something leaps from a distant asteroid with a large palace and lands on a minature asteroid next to the one everyone is on. The figures gigantic body leaves no second guessing as to who he is.)

Lie Ren: It's Shinnokal-El!

Kitana: Shinnokal-El!

(Everyone turns turn to face Shinnokal-El. As well as looking like a souped-up crossover between Superman and Shinnok, his voice sounds like the two of them as well.)

Shinnokal-El: You seek to destroy me. Good...

(Everyone begins to hold their heads in pain as the rage surges through them.)

Shinnokal-El: Give in to your rage. Unleash your aggression. FIGHT!!!

(The two forces, with the exception of Tarantula and Batman, charge at each other. Just before everyone collides, the scene cuts to darkness. It is replaced by pictures of the ensuing brawl. Liu Kang throws a flying kick at Coco Adel. Jacqui and Ironwood pound away at each other. Catwoman blocks a high kick from Ty Lee. Scorpion throws his spear as Jaune dives in with his Crocea Mors. Baraka and Adam Taurus draw their blades. Nora Valkyrie summons lightning while Shang Tsung readies a soul attack. Kano grabs Roman by the throat. Cassie tries to fight off Emerald Sustrai, who has her wrapped in the chains. Reaper leaps back from an ice-slide of Sub-Zero's.)

Narrator: The rage flowing through them, Tarantula and his allies battled the invaders with a diabolical elation. But as the dust settled, it was clear that neither side had won. The few comrades still standing tried to free themselves of the bloodlust.
