Joker: Last Laugh was a six-issue miniseries which supported the Joker’s Last Laugh crossover event, which itself included special tie-ins for every other ongoing series at the time. It featured the Joker taking control of the world’s super-villains with Joker Venom, turning them all into cackling maniacs completely obedient to him.

Wonder Woman is featured only as an impersonation by Lady Spellbinder in this issue.
