(At Watchpoint: Antarctica, the rebellion is prepared to visit the alternate universe where the Fall of Beacon failed.)

(In Vale, the Huntsmen are seen fighting Arthur Watts, Jaune Arc is seen following the villain until he slips and falls down. Then Ruby Rose helps him to get up as Glynda approaches them, showing disappointment towards Jaune)

Glynda: I told you to not make a single mistake, Jaune!

Jaune: Come on, Headmistress. I just went to the restroom. Not everything is done as fast as possible, okay.

(Then Yang Xiao Long and Velvet Scarlatina follow Arthur Watts until they find out something the villain is working on)

Velvet: What's that thing?

Yang: (activates her semblance) Breakable, I hope...

(As Arthur Watts tries to shoot the Huntsmen, Jaune throws his sword at the weapon, destroying it, then Ruby Rose shoots the villain. Then the rest of the Huntsmen arrive as Weiss freezes Arthur Watts)

Arthur: Wait for me... I'm escaping in a few days...

Nora: (draws her hammer) A broken leg will make it difficult.

(Arthur Watts is taken away as Ruby and Jaune approach the Huntsmen)

Jaune: My apologies for my fluke.

Ruby: That's okay. You're forgiven.

Weiss: Now let's clean up the mess.

Blake: Just a moment.

(As Blake mops up, a portal is open, revealing Lucas, Olivia and Neo)

Ozpin: (comes in) Who are you guys?

Yatsushiro: And why is Neo with you?

Sombra: It's a long story...

(One minute later)

Overwatcher: In my world, Superman killed Lex Luthor. Then he and what used to be the Justice League decided to take over the world.

Neopolitan: I am part of the rebellion forces, as you can see.

Ren: Hmmm... I see... So in your world you're not a criminal.

Sombra: Not anymore.

Overwatcher: Most of the heroes and military soldiers, including police officers obey the Justice Lords. They have even lobotomized criminals, including your enemies.

Ozpin: Even the Huntsmen obey these Justice Lords?

Neopolitan: Unfortunately...

Team RWBY: We're going with you.

Jaune: Me too.

Nora: Let's break some legs.

Ren: I'm in. (to Pyrrha and Team CFVY) Pyrrha? Team CFVY?

Coco: We're in.

(Back to Earth-50, In Metropolis, Justice Lords Superman is seen having a dinner with Lois Lane, then he notices something wrong)

Superman (Justice Lords): Cold.

Lois Lane: This soup must be served cold!

Superman (Justice Lords): Not the soup. It's you! What's the problem, Lois?

Lois Lane: Two years later and you didn't realize yet? Why do you think I'm holding Lucas' photos instead of yours?

Superman (Justice Lords): Here it goes...

Lois Lane: The world is under permanent control, no press freedom, and what's the problem?

Superman (Justice Lords): We told it too many times before. Can't you see it another way, dear?

Lois Lane: I like my way to see things. You're the one who doesn't see where this will stop. And I'm glad to see there are people who share my viewpoint.

(Suddenly the communicator beeps)

Superman (Justice Lords): Just a moment. (communicates) Hi!

Batman (Justice Lords): Sorry. But I need you and the others.

Superman (Justice Lords): I'm busy.

Batman (Justice Lords): Now!

Superman (Justice Lords): (to Lois) I gotta go.

Lois Lane: We're not done talking.

Superman (Justice Lords): I know. We're surely not done.

Lois Lane: You can't dispose of me like I was a hysterical woman.

Atlas Soldier: (blocks her) You know the rules. No going out, no visit and no phoning.

Lois Lane: I can't express, I can't think...

Atlas Soldier: It's just for a while, miss. They promised.

Lois Lane: Fools...

(Cut to the Batcave, the Justice Lords is watching the Justice League fighting Lex Luthor)

Batman (Justice Lords): We're watching another dimension... Livestream...

Wonder Woman (Justice Lords): Just like ours.

Batman (Justice Lords): Almost. Their Flash is alive.

Superman (Justice Lords): Yeah... So is their Luthor.

(The fight in the parallel universe goes on)

The Atom (Justice Lords): This is sad...

Green Lantern (Justice Lords): It's a mess, so was our world.

Hawkgirl (Justice Lords): A shame we can't help...

Batman (Justice Lords): Who said we can't?

(The portal is open. Then the Justice Lords walk away, then Superman stands besides him)

Superman (Justice Lords): The bat was busy, huh?

Batman (Justice Lords): Something else to do here?

(The Justice Lords come close to the portal)

Aquaman (Justice Lords): Can this get us to another dimension?

Batman (Justice Lords): If we decide so.

Raven (Justice Lords): Why don't we go?

Batman (Justice Lords): We're talking about helping. But would THEY accept OUR kind of help?

(Some minutes later, in the Justice League Universe, the Justice League finally defeats Lex Luthor. Then Justice Lords Martian Manhunter comes in through the portal)

Martian Manhunter: Who are you?

Martian Manhunter (Justice Lords): I... am you!

(Some seconds later, Raven, Green Arrow, Aquaman and The Atom are seen alongside the Justice League, listening to the alternate Martian Manhunter's speech about the supposed crisis)

Martian Manhunter (Justice Lords): The dimensions seem to be colliding with each other. My world's Batman asked me to gather some help.

(Raven is seen alongside Batman)

Raven: It's not what he's saying it is.

Batman: This must mean there is something behind the scenes.

Raven: Indeed.

(Justice Lords ends his speech without knowing that Raven already read his mind)

Superman: Are you in?

The Flash: I'm in.

Hawkgirl: Me too.

Wonder Woman: Let's go.

Green Lantern: I'm on it.

Aquaman: I don't know about you five. But I'm going with them.

(The Justice League goes to the white place with no windows or doors)

The Flash: Where are the doors and windows?

Raven: About this...

Batman: He duped us!

Green Arrow: What?

(Suddenly the Justice League is electrocuted)

(Then the Justice Lords watch them)

Superman (Justice Lords): They're gonna thank us later.

Hawkgirl (Justice Lords): Oops!

(Hawkgirl is seen struggling as she uses her Nth Metal Mace. Then Justice Lords Green Lantern approaches and hits her as the Justice League gets unconscious)

(The heroes are seen with the parallel universe Huntsmen)

Weiss: So this is the alternate universe...

Jaune: And this must be the rebellion base.

(Some heroes are brought to Earth-50. But the parallel Justice League is in trouble. Will the rebellion save them?)
