Batman: Arkham - Episode 9: The Joker's Party (Finale)

Season 1: Asylum

Batman arrives to face Poison Ivy. Ivy says that she thought the Titan was hurting the plants, but it was actually making them stronger. She summons a colossal plant and teams up with it to fight Batman. Batman wins, causing Ivy and the plant to sink. Upon leaving, The Joker says his party is about to begin. Batman heads to the Visitor Center. Batman arrives and sees The Joker, sitting on a throne, who sends out two Titan mutants. Batman defeats them, and The Joker reveals Gordon tied up. Drawing a gun with Titan, he shoots Gordon. Batman jumps in front to save him. He resists the drug, which makes The Joker furious. Declaring that he has nothing left to live for, he shoots himself. Helicopters fly over Arkham. From the roof, the mutated Joker emerges with Batman. Unlike others, The Joker has kept his mind, and taunts Batman into giving in to change. Batman injects himself with the antidote. The Joker sends out his henchmen, while showing off for the cameras. Batman defeats them, and pulls out The Joker, who falls into an electrical circuit. The Joker rises once more. Batman sprays the explosive gel onto one of his fists. Saying that he will never let him win, Batman punches the Joker in the face, exploding and knocking the Joker unconscious. After the fight, Gordon says that the Titan's effects are starting to wear off on Joker and his men, and that Batman deserves a rest, but Batman is informed that Two-Face is robbing a bank. He flies through the night in the Batwing.
