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.

He flies through the night in the Batwing.
