Lou

Lou is one of Harley Quinn's two pet hyenas, companions to the Clown Princess of Crime alongside his fellow hyena Bud. The pair serve as Harley's loyal animal sidekicks within Gotham City.

Debuting in the pages of Harley Quinn #4 back in 2001, Lou is one of those delightful corner-pieces of the DC Universe's Modern Age that true Gotham devotees love to spot. Sharing panel space across the years with the likes of Harley Quinn, Poison Ivy, Batman, and Bruce Wayne, Lou has kept genuinely colorful company throughout a surprisingly long publishing life stretching all the way to 2025. Most at home in titles like Batman: Li'l Gotham and Batman, this is a character whose staying power across nearly a quarter-century speaks to a certain irresistible charm that DC creators keep finding reasons to revisit.
