Klarion the Witch Boy is a supervillain appearing in American comic books published by DC Comics, having first appeared in The Demon #7 (March 1973) and was created by Jack Kirby. The character is typically portrayed as a powerful but mischievous, immature extradimensional warlock who serves as both the archenemy of Etrigan the Demon and is a reoccurring adversary for various mystic characters and teams in the DC Universe. The character has also been adapted in media, having made appearance in animated series such as Batman: The Animated Series, Young Justice, and Justice League Action.
