Arkham City IncidentEdit
After Batman escapes from Wonder Tower, Joker announces that he has taken Talia al Ghul to the Monarch Theater and is planning on killing her unless Batman shows up. Batman arrives at the theater where Joker demands, at gun point, that Batman hand over the Titan cure.
Confused at Joker's statement, as he had thought Joker had already stolen the cure, Talia runs her sword through Joker and reveals that she had stolen the cure from Harley Quinn earlier in the Steel Mill.
Realising too late that the Joker Talia had killed was not the real Joker, Batman watches as the real Joker kills Talia with a gun from the theatre's upper level, while the one Talia had "killed" reveals himself to be Clayface, who accepted Joker's offer to fill in for him simply for the role of a lifetime.
Taking the cure from Talia's corpse, Clayface and Batman fight, with Batman using Freeze Blasts to freeze Clayface and carve him up with Talia's sword.
With Clayface apparently defeated, Joker detonates the theatre's floor, causing it to collapse and reveal Ra's al Ghul's Lazarus Pit directly underneath the theatre.
As Batman defeats Clayface a second time and retrieves the cure, Joker attempts to gain immortality through the Lazarus Pit but Batman buries the pit before Joker could enter it.
Demanding that Batman give him the cure, appealing to the hero's "no killing" code, the Joker becomes impatient when Batman briefly considers allowing him to die. Attempting to take the antidote by force, Joker causes Batman to drop the vial; shattering it on the floor.
Batman states that the "funny" part was that he had actually decided to give Joker the antidote before he attacked him. Joker agrees that was actually hilarious and dies laughing. Batman carries Joker's body out of the theatre past his goons and Harley Quinn, and leaves it on the hood of a GCPD patrol car outside of Arkham City.
- The movie that the Waynes went to see has fluctuated between the The Mark of Zorro (1920) starring Douglas Fairbanks and The Mark of Zorro (1940) starring Tyrone Power and Basil Rathbone.
- "The Terror" being shown on the projector is in fact a movie that Jack Nicholson (The one who played the Joker in Tim Burton's Batman Movie) was in. The Terror is also a fictional movie that starred Basil Karlo's, but the movie was rebooted with new actors, making Karlo's go insane and get in a body mutilating accident, leading to the creation of Clayface.
