(After the original Batman's defeat, Superman returns to power and becomes Brainiac Superman.)

(At Stryker Island, Supergirl is seen in the red sun prison cell while seeing Brainiac Superman and the brainwashed Batman)

Superman: What is it gonna be, Kara?

Supergirl: I'll never serve you!

Superman: You have time to comply about this. Think twice or you share his fate!

(The duo leaves. Then a trio comes in. One of the three looks like Batman, the other has a metallic right arm and the third is a young boy)

Supergirl: Another Batman?

G. Batman: (takes off his mask) My name is Neo Wayne. I'm Bruce's adopted son. The kid is James Romanoff.

James: I'm not a kid!

W. Soldier: Yes, you are.

G. Batman: The man is Bucky Barnes, the Winter Soldier.

Supergirl: How did you find me?

(Gamer Batman puts his mask back, then uses his remote hacking device to open Supergirl's cell)

G. Batman: I hope this has answered your question, Kara Zor-El!

Supergirl: (gets out of her cell) How do you know my name?

G. Batman: I am intelligent.

James: So intelligent that he made sure all alarms were shut off.

G. Batman: Enough talk. Let's get outta here!

(Then he uses Mega Man's teleport powers and teleports himself and the trio off)

(Some weeks later, at Atlas. The members of the New Insurgency are gathered.)

G. Batman: Some of you already know what this matter is about, but I want the rookies to know what we're dealing with.

Deathstroke: (approaches Neo) Can we talk in private?

G. Batman: Winter. Brief them of the situation.

Winter: Yes sir.

(The duo walks away as Winter starts explaining)

Winter: This is Superman, the one who used to be...

Deathstroke: (to Neo) Are you sure we can trust her? I really don't want another Kryptonian playing Almighty around here.

G. Batman: Unlike Kal, Kara regrets her actions, and she is ready to make amends.

Deathstroke: Well... I just don't trust her...

G. Batman: I don't blame you, Deathstroke. What you've been through really messed you up.

(Then the return to the meeting)

Winter: We need to stop Superman before he gets to find us. Thanks to our leader, we found a reserve of kryptonite and we will use it to stop Superman once and for all!

James: Our comrades will finally be avenged!

(Flashback)

(Rogue is seen hiding among the mutants, but the Regime Soldiers shoot them down)

R. Soldier: Hands up!

(Rogue raises her hands)

R. Soldier: Good girl. Take her!

(Then Gamer Batman comes in and overwhelms some of the Regime Soldiers while piloting a warthog as Harley Quinn shoots the other Regime Soldiers)

Harley Quinn: EAT LEAD, BAD BOYS!

(As Harley Quinn keeps shooting the Regime Soldiers down, The Gamer Batman approaches Rogue)

G. Batman: Want a ride, cutie?

Rogue: I'm all yours, sugar!

(Then Rogue gets in the warthog and the trio goes away)

Harley Quinn: WOOOOHOOOOO!! NEVER HAD THIS MUCH FUN!!

(Then Superman pierces through Tadashi's heart as the surviving students watch in horror before being stepped in by the Regime Soldiers. Hiro is seen unable to hold his anger as he decides to attack the Regime Soldiers)

R. Soldier: Another punk?

(Hiro kicks one of the Regime Soldiers in the face, then does a cock shot in the other, but then the third Regime Soldier manages to pin him, only to be hit by a stone. Then the newest Robin Carrie Kelley is seen with her gunsling)

Superman: TAKE HER!!

(Then the Regime Soldiers are about to shoot her, but a black and grey energy streak comes in and incapacitates all of the soldiers, then takes the two kids.)

Superman: Hmm... Not even Barry could be this fast...

(At the New Insurgency Base, Neo, Carrie and Hiro are seen as Carrie kisses Neo in the lips)

Robin: I knew you would come and save me, honey.

Hiro: That alien will pay for what he did to Tadashi!

(At Kuoh Academy, Black Adam is seen killing almost all members of Sona's peerage because they refused to join the Regime.)

Black Adam: Wrong choices lead you to only one way. Death!

(As Black Adam leaves, Sona Sitri shows up)

Sona: You'll pay for this!

(Then Gamer Batman comes in)

Sona: I know what you'll propose. (extends her handshake) I'll join the Insurgency!

(The two shake hands)

Korra: I failed... I failed everyone... I was supposed to be the Avatar...

(Then Neo, Hiro and Sona come in)

Korra: Who are you?

G. Batman: Sorry about your friends. We feel your pain.

Korra: You do?

(Gamer Batman nods)

G. Batman: I failed to defend my father, who was the original Batman.

Korra: Wait, so this means...

(Korra remembers the image of the brainwashed Batman, now known as Black Oracle.)

Korra: So what happened to the original Batman...

G. Batman: Unfortunately he is the Black Oracle.

Sona: I failed to defend my friends too... I wasn't there for them when they needed me...

Hiro: Same about Tadashi... he was my brother... now he's... gone...

G. Batman: We need members for our new Insurgency. Do you accept to join us?

Korra: (determined) I do!

(At New York, Wonder Woman is seen cutting Captain America's head, then piercing Black WIdow's heart)

Wonder Woman: Freedom is a lost cause! The Regime created peace!

(As Wonder Woman flies away, James Romanoff is seen)

James: That amazon whore killed my family... But I will not let this be! She will pay for what she did! From now on, I am Captain America!

(Some days later, James and Neo are seen defeating an army of Regime Soldiers, then James breaks Winter Soldier free)

W. Soldier: Where's your father?

G. Batman: He's dead, just like his mother...

James: That amazon whore killed them. And I'll make her pay!

(Flashback Ends)

James: The Regime will pay for what they did!

(Suddenly the Ace Operatives come in)

Clover: We have a problem. They found us!
