(Green 10 is seen as Big Root, using his powers to turn a wasteland into a garden full of flowers before reverting back to his human form)

Green 10: I wonder what I would have been without the omnimatrix...

(Suddenly a beautiful woman approaches him)

????: You know... You're very different from the others.

Green 10: What others?

????: Why... The other supposed heroes, of course. You're the one who really deserves to be called as such. Unlike the so-called Justice League.

Green 10: So... Who are you exactly?

????: Oh, please. Call me Poison Ivy. You know... The very wasteland you turned into this beautiful garden would be turned into another part of these polluting concrete jungles. These other men simply harm Mother Nature and think they won't be punished.

Green 10: It's true that mankind makes Mother Nature suffer. And sometimes I hate myself for that.

Poison Ivy: I know...

(Suddenly a monster emerges from the lake)

Green 10: Hey. I know you.

????: You do?

Poison Ivy: So you heard about Swamp Thing?

Green 10: Yes. And the alien I used to make this wasteland more... Green... It's based on him.

Swamp Thing: I'm glad you know about me. What's your name?

Green 10: Ren Tennyson. Also known as Green 10.

Swamp Thing: It's good to know that someone is trying to save the green.

Green 10: Without the green, the entire planet would be doomed.

Poison Ivy: I agree. By the way, I heard that you're after Ra's Al Ghul. Let me tell you a secret about his plan. (whispers in Green 10's ears) I heard that he's planning to destroy Drake City, Gotham, Metropolis and Central City by using atomic bombs. Now I see why you hate him so much.

Green 10: Thank you for the information. It's going to be useful.

Poison Ivy: Well. I gotta go. Nice to meet you.

Green 10: Likewise, Ivy. (to Swamp Thing) What about you?

Swamp Thing: I'll be staying here. To ensure the green around here won't be harmed.

(Meanwhile in Lexcorp)

Lex Luthor: So Ra's is planning to destroy Metropolis with an atomic bomb.

Deathstroke: The same thing will happen to Central City, Drake City and Gotham.

Lex Luthor: So it begins.

(Meanwhile in the Watchtower)

Batman: Green 10 gave us some useful information. It looks like Ra's Al Ghul is planning to destroy Metropolis, Drake City, Gotham and Central City with some atomic bombs.

Cyborg: So this must mean...

Batman: The final battle is about to begin!

(Ra's Al Ghul decided to create a Plan B. He intends to use atomic bombs to destroy Metropolis, Gotham, Drake City and Central City. Will our heroes manage to stop him?)
