(Green 10 is finally face to face with his archenemy)

Ra's Al Ghul: My brother was stupid by training you!

Green 10: At least he knew I could face you someday.

Ra's Al Ghul: You will soon regret it!

(Green 10 prepares to fight Ra's Al Ghul, who draws his sword and attacks him. Green 10 barely avoids, but manages to give a counter blow at Ra's Al Ghul.)

Ra's Al Ghul: Now I can see why the detective likes you...

(Ra's Al Ghul attacks again. But this time, he does it faster and scratches one of his arms, making Green 10 feel some pain.)

Green 10: OK... Time to get serious!!

(Green 10 decides to attack Ra's Al Ghul, who avoids each one of his attacks until the Tennyson kicks one of his legs, making him fall.)

Ra's Al Ghul: Damn it... That does it!!

(Ra's Al Ghul decides to try to pierce Green 10, but he easily breaks his sword, much for the demon's surprise)

Ra's Al Ghul: What the... How did you break my sword? Where did such strength come?

(In response, Green 10 punches his belly)

Green 10: So you really thought my strength came from my watch, didn't you, murderer? (punches his face) Ra's Al Malak taught me how to channelize my inner strength! (kicks him) He taught me to realize my true potential! (gives a 16-hit combo) That's why I thank him... (gives a final attack on him) for making me what I am today!

(Green 10 approaches his fallen archenemy)

Green 10: Now... I could have completed my vengeance... But he taught me that all lives must be spared, no exceptions.

(A portal appears, showing Batman coming out of it.)

Batman: I agree. (approaches Ra's Al Ghul and ties him up) There's been enough killing.

Green 10: (to himself) It's over... My parents can finally rest...

Ra's Al Malak (narrating): And that's how the legendary Green 10 won one of his greatest and hardest battles.

(The next scene shows the Mysticons, Kitty Boon and Fire hugging and kissing Green 10)

All Girls: We love you, Ren.

(Ben, Gwen and Max are seen watching the scene)

Ben 10: Well... When everything ends well...

Gwen: Yeah... (to Ben 10) But aren't you supposed to be jealous or something?

Ben 10: Ren has his girls, I have my girls.

Max: That's true. But I must admit. Ren is a good grandson.

Ben 10: You're right, grandpa... He's a cool guy.

(Meanwhile at Arkham Asylum, Batman is seen taking his enemy/father-in-law.)

Batman: I have asked the commissioner to make a comfortable cell for you.

(Suddenly The Joker sees Ra's Al Ghul and taunts him)

The Joker: Look who's back home! (laughs maniacally)

Ra's Al Ghul: Grrr...

Batman: Your jokes are no fun at all...

(Cut to Lexcorp, Lex Luthor gives a money mallet to Deathstroke)

Lex Luthor: Thanks to you, Ra's Al Ghul got what he deserved. And besides, deal is deal.

Deathstroke: Glad to be of service, Luthor.

(At the Justice League Watchtower)

Superman: We had a hard mission today.

Green Lantern: The atomic bombs were about to detonate. But we could eventually stop the mass destruction.

Wonder Woman: The victory was hard. But once again, good triumphs over evil.

The Question: Thanks to Deathstroke, Luthor and Ren. Without their help, we couldn't have saved the cities from their imminent destructions. Their aid saved all of us.

Huntress: Do you think we can finally rest?

(Everyone looks at Huntress with serious expressions which indicates that their answer is no.)

Huntress: Yeah... Me neither...

(Some days later, Green 10 is seen overlooking Drake City before looking to the skies with pride. Then he is approached by Arkayna Goodfey and they have a passionate kiss)

(Back to Arkham Asylum, Ra's Al Ghul is visited by Deathstroke)

Ra's Al Ghul: I knew you would betray me, Slade...

Deathstroke: Yeah, Ra's. It looks like you lose. Did you really think that I would be loyal to you again? That kid may have spared your life. But he didn't forgive you for what you did to him, did he? That's right, Ra's Al Ghul. Your time... is over. (points the gun at Ra's) You die here. (about to pull the trigger) It was good while it lasted. We relieved one each other's boredom for a while. Yeah, Ra's. It was interesting.

(Deathstroke pulls the trigger and shoots Ra's Al Ghul in the head.)

(Back to Drake City, Green 10 and his newfound harem, including Cheetah watch the sunset)

Cheetah: So beautiful...

Fire: Yeah...

(And that's how Green 10 Begins comes to the end. With the hero proud of saving the world. Which challenges await him?)
