(In outer space, a giant spaceship is seen heading towards the Milky Way Galaxy. Inside of it, the Dark Union Heroes are seen being watched by Yellow Lantern and Black Adam.)

Y. Lantern: All Union Students are doing great.

B. Adam: We'll get to the destination, and convince the people about our intentions.

Y. Lantern: Superman, Omni-Man, Sirzechs, Ozpin, Hanzo, Nezu, Enterprise and Danzou will show them who are the heroes.

(At the Headmasters' Throne Room, Sirzechs, Ozpin, Hanzo, Omni-Man, Nezu and Danzou are seen sitting in their thrones along with Superman and Wonder Woman as they look at the hologram of the Milky Way.)

Ozpin: Since we put those traitors in their cells, we can go now to another universe, where everything seems peaceful.

Sirzechs: Indeed, this world will be ours, and nobody will stop us.

Nezu: We will make everyone as long as they obey us.

Danzou: If they don't...

Superman: We'll kill them or send them to prison.

W. Woman: No mercy.

Omni-Man: We already know the plan.

Superman: Yes, to make them obey our commands and exterminate all criminals.

(Then General Ironwood and Headmistress Enterprise come in and bow to them.)

Ironwood: We're going towards the Milky Way Galaxy.

Enterprise: We will arrive in there within 30 hours.

Superman: Good, we'll be in touch.

Ironwood: Understood.

(Then they leave as Superman looks back to Ozpin.)

Superman: Nobody will stop us.

Ozpin: Indeed.

(Meanwhile at Ladybug's Omniverse, Marinette DuPain Cheng is seen watching over Paris along with her friends Adrien Agreste and Mark Grayson until a portal opens up.)

Ladybug: What the?

Cat Noir: Who's that?

Invincible: An enemy?

(Then they see Cosmic Virgo coming out of it. Cat Noir and Invincible get in their fighting stances.)

C. Virgo: Calm down, I didn't come to hurt you.

Ladybug: Who are you?

C. Virgo: I am Cosmic Virgo, protector of the Omniverse.

Cat Noir: Omniverse?

C. Virgo: Yes, and I need your help.

Invincible: Uh... with what?

C. Virgo: There's a threat known as the Dark Union, which is invading Bat 10's Universe.

Ladybug: And you need us to get in there to help its heroes?

C. Virgo: Exactly. And just another thing.

(Cosmic Virgo uses his powers and brings Michael Howard, also known as Spider-Man, back to life.)

Spider-Man: Huh? Am I...

(Then Ladybug excitedly tackles Spider-Man into a hug.)

Ladybug: Senpai, you're back.

Spider-Man: Marinette? Is that you?

Invincible: (to Cosmic Virgo) How did you do that?

C. Virgo: I am what you call a surprise box.

Cat Noir: That makes sense...

Ladybug: (bows) Thank you, Cosmic Virgo.

Spider-Man: You revived me?

C. Virgo: Yes, and I need Marinette and her friends to help Bat 10 and his friends in their fight against the Dark Union.

Spider-Man: You can count us in. I couldn't finish the fight against my world's Union, but I'm sure I'll finish this one.

(Then Cosmic Virgo opens two portals.)

Invincible: (confused) Aren't you coming?

C. Virgo: I need to help other heroes in need at Lyon Bardot's universe.

Cat Noir: Come on, guys. We must find this Bat 10 and help him.

(Then they leave through the portals.)

C. Virgo: Now to help Lyon and his team.

(Then the screen fades out.)
