DC Just Brought Back the Joker’s Most Terrifying Form

The Joker once cleverly tricked the powerful fifth-dimensional imp, Mister Mxyzptlk, into giving him almost all of his power. Calling himself Emperor Joker, he then used this cosmic ability to reshape the entire universe to match his twisted vision. Because Mxyzptlk’s powers were based on imagination, the Joker effectively controlled all of reality. Superman was only able to defeat him by using the Joker’s obsession with Batman against him, and thankfully, the Joker lost his reality-warping abilities. Everyone believed he’d gone back to being a regular criminal, but the comic DC K.O. #3 surprisingly brought Emperor Joker back with all his madness intact.
