Joker / Mask #1

This 2000 DC/Dark Horse crossover brings together two of comics' most delightfully unhinged characters, and the cover by Ramón Bachs sets the tone perfectly — the Joker gleefully hoists the glowing Mask artifact aloft while a hearts-eyed Harley Quinn swoons beside him, with the Mask's mischievous green-faced alter ego lurking large in the background. The animated-series-inspired art style gives the whole scene a bouncy, anarchic energy that feels perfectly suited to a story where the Joker might actually get his hands on the world's most chaotic magical object. Writer Henry Gilroy and artist Ramón Bachs kick off this four-issue miniseries with a premise that practically sells itself.
