(Batman, Ruby Rose and Kevin Rose are seen discussing plans to defeat Superman once and for all)

Ruby: While Kevin helps the others to hold off the Regime Forces, I and my team will evacuate the people in Vale.

Kevin: That sounds like a good plan. But one of them will be really tricky.

Batman: Doomsday…

Kevin: But I believe we can succeed.

Ruby: OK. Let's go!

(Samurai Jack is seen fighting Hawkgirl. As Black Adam tries to hit the samurai. But Super Sonic Blue Kevin comes in  time and attacks him)

Super Sonic Blue: Go back to your own universe, invader!

Black Adam: The warriors around here are weak. This world suffers with this!

(Black Adam throws a car, but Kevin blasts it. Then Black Adam throws another car, but Kevin pulverizes it again. Then another car thrown, only to be blasted again. Then Black Adam tries a front attack, but Kevin blocks him)

Black Adam: You're nothing but a blue hedgehog!

Super Sonic Blue: My powers are beyond your level, Black Adam!

(As the fight starts, Kevin shows exactly what he meant, easily defeating Black Adam)

Super Sonic Blue: Your evil ends here!

(Then Sinestro tries to attack Kevin, but the construct breaks at the moment it touches the hedgehog. Then Kevin overwhelms Sinestro, forcing the Sinestro Corps to retreat, except for Hal Jordan)

Super Sonic Blue: This is your chance, Hal Jordan. Take it.

(Then Hal Jordan removes his yellow lantern ring, giving in. Then Kevin smiles before knocking out the regime members one by one. Then he heads to Vale, where the White Fang is trying to hold the Atlanteans army back, but it's in vain. Then Kevin comes in, becomes Ice Sonic and freezes the tidal wave created by Aquaman.)

Aquaman: So you're ready to face the king of Atlantis.

Ice Sonic: You can bet I am!

(Then the combination of amazons and spartans led by Artemis and Pyrrha attack the atlanteans, forcing them to retreat)

Aquaman: You're not going to escape without an injury!!

(Kevin becomes Super Sonic Blue again and fights Aquaman. The hedgehog has an advantage since they are fighting at the surface. Then he easily defeats the king of Atlantis.)

Super Sonic Blue: If someone was supposed to run away, it's you!

(Then Pyrrha comes in)

Pyrrha: You're so wonderful, love.

Super Sonic Blue: You too, my hot spartan.

Artemis: I got jealous, you know.

(Then Team RWBY comes in)

Weiss: Most of these dolts from the Regime have been taken care of.

Blake: We still have to deal with the remaining members and…

(Suddenly Doomsday lands roughly. Having no other option, Kevin tackles the monster and takes him to a wasteland, where there's no one to be harmed)

Doomsday: (gets up) I live to kill anyone who stands in my way!

Super Sonic Blue: Prepare to be disappointed!

(Kevin fights Doomsday. As he foresaw, the monster is actually tricky at the point he adapted to the abilities he uses. Then Kevin decides to use his chaos control and manages to knock Doomsday out with a super spin dash attack)

Super Sonic Blue: Doomsday is not today!

(Kevin and Doomsday are somehow transported to the Injustice Universe, at the Fortress of Solitude. Then Kevin throws Doomsday at the Phantom Zone before feeling another presence)

Super Sonic Blue: So we meet again…

(Superman is seen from above)

Superman: I knew you would come here eventually!

Super Sonic Blue: You invaded my world, I invaded yours. So I guess we're even.

Superman: Not for much longer!

Super Sonic Blue: It wasn't enough to invade parallel dimensions? You also kill innocent people?

Superman: Disobedient children will be punished!!

Super Sonic Blue: And since when do you take decisions?

Superman: The decision is mine! It became mine when I was turned into a weapon of mass destruction!!!

Super Sonic Blue: That's why there is always one judging you. And my world's Superman would judge you as well!

Superman: I know. That's why he'll be the next on my list! And after I kill him, I'll bring his Lois here! And when she finds out how this world became…

Super Sonic Blue: She will be afraid, and disgusted by you!!

Superman: She will be alive!!!

Super Sonic Blue: I'm really glad I haven't lost my…

Superman: My beloved one was taken away from me!!!

Super Sonic Blue: And you took the freedom of the worlds you invaded! Time to give it back!!

(Kevin fights Superman. Kevin knew that this fight would determine the fate of the multiverse, and there's no way to reason with Superman. Then he goes all out, and after exactly five minutes of fight, Kevin finally defeats the fallen man of steel, ending his reign of terror.)

Super Sonic Blue: Your reign… is over!!

(Superman tries to hit Kevin with his heat vision, but Kevin blocks it and uses a powerful ki blast which knocks him out. Then Kevin returns to his base form)

Kevin: You're not going to terrorize the multiverse anymore!!

Superman: Fear… is the only thing these people understand… Someday you're going to learn this…

(Then Zero comes in with his Z-Saber coated with kryptonite and rage as clear as day in his eyes)

Zero: I'll make you pay for turning Iris into a maverick! Prepare yourself!!

(Zero prepares to kill Superman)

Zero: DIE!!!

(Then Iris comes in)

Iris: STOP, PLEASE!

Zero: Iris?

Iris: Zero, please. Don't you remember? Robots can't hurt humans.

Zero: He… he turned you into a maverick, manipulated your brother, and tried to destroy Abel City!! He is too far from being a human!!! He is a monster!!! A maverick!!!

Iris: (cries and hugs Zero) Please… I know I'm not the Iris you once knew anymore… but we can start again… if not for me, spare his life for your friends…

(Zero remembers his missions with X, Axl's bad puns, and his other good times. Then he calms down and hugs Iris)

Zero: Iris… I forgive you…

(Then Batman and the other heroes come in as Hiro approaches Superman)

Hiro: If I really wanted, and I still do, I would already have killed you… but Tadashi would never allow me to do so…

Batman: (approaches Hiro) And besides, there's been enough killing!

(Superman was finally defeated. The multiverse is safe. The Regime is finally destroyed. Thank you, heroes.)
