Fan CastingBatman: Arkham - Episode 9: Joker the Immortal (Finale)

Batman arrives at the Monarch Theater, where Joker is holding Talia hostage. The Joker demands the cure for Batman, which leaves him confused. Talia breaks free and stabs the Joker with her sword, killing him. She explains that she stole the cure while Harley Quinn took it. With the Joker dead, Batman begins to connect the dots, but realizes too late that this wasn't the real Joker. From the upper level, the real Joker shoots and kills Talia. The Joker who was killed reveals himself as Clayface. Using the weapon Freeze gave him and Talia's sword, Batman confronts and defeats Clayface, but the floor is blown up, causing them to fall into the room where the Lazarus Pit was. Batman once again defeats Clayface. The Joker prepares to enter the pit and achieve immortality, but Batman destroys the pit, which causes an explosion. Batman retrieves the cure and drinks half of it. The Joker appeals to Batman's no-kill code, asking for the cure. Batman reflects on the deaths the Joker causes, which makes the Clown impatient, lashing out at Batman with a knife, but this only causes Batman to drop the cure, which crashes to the ground. Batman says the funny part is that he was actually going to give the antidote to The Joker, who laughs, and dies with a smile on his face. Batman carries Joker's body past Harley Quinn and is watched by Catwoman. Outside, Gordon asks what happened, but Batman just leaves the body on the hood of a police car, and leaves without saying anything.
