(The engineers are almost finishing the weapon. Then Sora draws his Keyblade as he prepares for the worst.)

Sora: I better prepare in case of Superman sending his goons to invade this place.

(Then he uses steps out of the academy and sees something which confirms his suspects. Anti-Aqua, Anti-Riku and Anti-Sora are seen.)

Sora: I'm impressed Superman managed to build a replica of my anti-self...

Anti-Riku: Allow me to deal with him, Anti-Sora.

Anti-Sora: Don't you dare to disappoint Lord Kal-El, Anti-Riku.

(Then Sora and Anti-Riku approach each other.)

Sora: You will fail, Heartless!

(They fight. Knowing that the Anti-Riku he is fighting is just a replica made by Brainiac Superman, Sora simply uses his heart and earns the victory over him.)

Sora: Superman needs to send better soldiers!

Anti-Aqua: All humans... will be extinguished... and there's nothing you can do to stop it!

Sora: It won't prevent me from trying!

(They fight. Despite having already fought Anti-Riku, Sora could still fight due to not having used all of his power. Anti-Aqua tries her best to bring down the keyblade master. But just like he did against Anti-Riku. Sora simply used his heart and manages to defeat her.)

Sora: I'll never give up!

(Then Anti-Sora approaches him and the two exchange glances.)

Anti-Sora: You may have won the battles... but in the end, you already lost the war!

Sora: I fought various wars... especially those I couldn't have possibly won. But I never gave up! What did that make me? A hero!

Anti-Sora: In the end, heroes will fail someday. And when that happens, darkness will consume the world.

Sora: I'm done being lecture by an evil replica of myself! (draws his keyblade) Time to face you head on!

(They fight. Unlike the replicas of Anti-Riku and Anti-Aqua, Anti-Sora fought on par with his counterpart. But Sora could still use his heart to keep fighting. Then after some minutes of fighting, Sora manages to defeat his evil self.)

Sora: Good thing I could hold my own...

(Then Future Sinestro comes in)

Future Sinestro: Human scum... You really think people deserve freedom!

Sora: We Keyblade Master fight to inspire courage, hope and compassion!

Future Sinestro: Fear is the only think mankind understands! And I'll show you this!

(They fight. The fear of the people empower Sinestro and this becomes a big problem for Sora to handle. But then he remembers that he didn't use his full power yet. Then he decides to go all out and manages to fight on par with the leader of the Sinestro Corps and after using a powerful Keyblade Blast, he manages to defeat Sinestro.)

Sora: And for mankind, I triumph once again!

(Then Sora returns to Neo Beacon Academy and sees the weapon completed. Then Kevin comes in.)

Kevin: I can see the weapon is ready.

Hiro: Now we just need to blast Superman's brainiac enhancements and finish this war.

(Then a Blue Lantern Ring comes in and approaches Kevin)

B.L. Ring: Kevin Rose.... You have the ability to instill great hope... Welcome to the Blue Lantern Corps.

(Then Kevin sees the ring attach into his finger and becomes a Blue Lantern.)

Ben 10: Now, let's go and finish Superman once and for all!

(The final battle is about to begin. Can our heroes win this one?)
