- Complete Monster: The Joker and his gang start by raiding a chemicals factory, with Joker using his gas on a night watchman, who is brought into Arkham Asylum Laughing Mad; Commissioner Gordon says the man is lucky, as most victims Die Laughing. Batman confronts Joker and his gang, but is sprayed with some of the gas; he manages to escape before a bomb set by Joker explodes. A week later, having recovered from the effects, Batman manages to escape Arkham and confront the Joker again. This time, Joker plans to use a hot air balloon and drop "laughing bombs" filled with his gas, resulting in all of Gotham City being Driven to Madness, with many dying.
