Max's Harley Quinn animated series introduced one of the darkest, most guilt-driven interpretations of Batman and his personal loneliness. The Harley Quinn television show follows Harley Quinn and her girlfriend Poison Ivy as they strive to become respected supervillains in Gotham City. Along the way, Harley faces off against her ex-boyfriend the Joker, builds a crew of criminal friends featuring Clayface and King Shark, and pursues a loving relationship with Poison Ivy. Harley Quinn has been praised for its darkly comedic rendition of the DC universe's various superheroes and supervillains, especially with its version of Batman.
