Joker / Mask

In this 2000 Dark Horse miniseries, writer Henry Gilroy and artist Ramón Bachs pit the anarchic Joker against the reality-warping chaos of the Mask, forcing Batman, Harley Quinn, and Poison Ivy to contend with a truly unpredictable fusion of madness. The four-issue run explores what happens when two forces of pure mayhem collide, with the Joker acquiring the Mask's power and turning Gotham into a surreal, violent playground. It's a cult-favorite crossover that leans into the absurd, showcasing Bachs' dynamic art and Gilroy's knack for dark humor.
