(Kevin, Sora, Ryu and Blake are seen at Menagerie, where they find Sienna Khan and Ilia Amitola)

Sienna: So Brainiac's threat is for real, huh?

Kevin: Yes, Sienna. And I'm wondering if you and the White Fang could help us.

Sienna: Well... I can help you. But first I need some exercises before this.

Ryu: I would ask if you would fight me, and show me how you fight.

Sienna: Then let's begin.

(Sienna shows her abilities to Ryu, who also shows his abilities. Then Ryu eventually defeats Sienna Khan)

Ryu: Thanks for the exercise.

(Then the White Fang Soldiers come in)

WF Soldier: Sorry, lady. We have a problem.

Sienna: Brainiac?

WF Soldier: Yes.

Sienna: Very well. Ilia. Kevin. You're with me!

Ilia: Understood.

Kevin: Let's go!

(As the trio and the White Fang Soldiers walk away, Ryu and Sora notice some familiar presences)

Ryu: This evil energy...

Sora: I'm recognizing a familiar evil too!

(Then Juri Han and Xemnas come in)

Juri: Hello again, Ryu. As usual you're in good shape.

Ryu: I'm always training. That's why I'm always in shape for a fight.

Sora: I should know that you could come back.

Xemnas: Time to bleed, Keyblade Master!

(Meanwhile in Atlantis, the reformed Green Lantern tries to recruit Aquaman to join Batman against Brainiac. The king of Atlantis refuses to help and gets beaten up by Green Lantern. Then Steven Universe comes in and saves the duo from being attacked by Cheetah and Princess Morbucks)

Morbucks: Hi, Steven. Can I ask you a favor?

Steven: If it's to reveal the powerpuff girls' location, don't even bother, because I won't.

Cheetah: Well... At least you three can be tasty snacks.

Green Lantern: I will not be anyone's snack!

(Steven Universe and Green Lantern use their combined powers and manage to defeat the femme fatales)

Steven: I really can't believe we really did it.

Green Lantern: Me neither.

(Then Bane and Vilgax come in)

Steven: It looks like another duo of not worthy of our respect has come.

Bane: So you admit you never respected me, Steven Universe!

Steven: I don't respect those who don't deserve my respect!

Vilgax: Time to crush you all!

(Back to Menagerie, Ryu and Sora managed to defeat Xenmas and Juri. Then Epsilon and Razoul come in)

Ryu: Epsilon...

Epsilon: It looks like they decided to send puny humans to fight the mighty Epsilon?

Razoul: Time to cut you both in half.

(Ryu and Sora fight Epsilon and Razoul. The evil duo was having the advantage at first, but the heroes manage to use their combined powers and defeat them)

Sora: Take this!!

(Sora blasts the two villains away. Then the trio comes in)

Sienna: We took care of Brainiac's betas.

Sora: Good.

Kevin: Yeah. But we never know when they will attack Menagerie again. Therefore I guess Sienna is needed here.

Sora: I see...

(Then Ryu feels his evil energy growing)

Kevin: Ryu? What's going on?

(Then Akuma and Master Xehanort come in)

Sora: (growls) Xehanort...

(Back to Atlantis, Green Lantern and Steven Universe manage to defeat the big villains. Then Green Lantern gets a red aura)

Green Lantern: Break this!

(Green Lantern knocks both Bane and Vilgax out. Then Aquaman comes in)

Aquaman: I guess you both can be trusted.

Green Lantern: Will you join the circle of trust?

Aquaman: Sorry. But I'm needed here.

Green Lantern: I see...

(Then the red aura surrounds Green Lantern as he falls down)

Steven: Hal? Are you okay?

(Then two figures come in, one being familiar to Green Lantern and the other being familiar to Steven)

Green Lantern: Atrocitus?

Steven: Yellow Diamond?

(Back to Menagerie)

Kevin: Who are these two?

Sora: The bald one is the true leader of True Organization XIII. He is Master Xehanort.

Ryu: And the other one is my deadliest archenemy Akuma.

Xehanort: You know why I came here, don't you?

Kevin: Now I remember. You joined Superman and his regime.

Xehanort: And since you helped Sora to tear down the Regime, I seek revenge!

Akuma: Ryu. Time to succumb to your true power!

(Ryu struggles his inner monster, and thanks to Kevin's motivational words, he manages to break free from Satsui no Hado)

Ryu: I have fought this evil within me so many times. Now it's time to put you down, Akuma

Sora: Same goes to you, Xehanort!

(Ryu and Sora fight their archenemies and unlock their true potential. The fight was long and intense. But they eventually defeat their archenemies)

Kevin: Sora. That was awesome.

Sora: Thanks, Kevin.

(Then Peter Pan comes in)

Sora: Right on time, Pan. Can you take these two back to Disney Universe?

Peter Pan: Sure.

(Peter Pan creates some ropes with his pixie dust and takes the villainous duo away)

Sora: They won't need to know that.

Kevin: Who?

Sora: The Keyblade Masters.

(Back to Atlantis, Atrocitus tries to turn Hal Jordan into a Red Lantern, but he speaks his oath)

Green Lantern: In brightest day, in blackest night... No evil shall escape my sight... Let those who worship evil's might... Beware the power...Green Lantern's light!

(Green Lantern breaks free from Atrocitus' influence)

Green Lantern: I made various mistakes. But my willpower is stronger than anything.

(Green Lantern and Steven Universe decide to face their archenemies. As they go full power, they manage to defeat them eventually. Then Yellow Diamond gets up)

Yellow Diamond: This world is about to burn. And I'll be waiting for this moment.

Atrocitus: You will be driven by vengeance.

(Then they go away)

Green Lantern: The guardians will not need to know that.

Steven: Neither will the Crystal Gems.

(Back to Brainiac's ships)

Brainiac: Now the defenses are compromised.

(It looks like the enemy has made his next move. What are our heroes going to do? And what are Superman's loyalists planning to do? Stay tuned for more.)
