Wildcat is the name of several fictional characters, all DC Comics superheroes. The first and most famous of these is Ted Grant, a long-time member of the Justice Society of America. Created by writer Bill Finger and illustrator Irwin Hasen, Grant first appeared in Sensation Comics # 1 (January 1942). A world-class heavyweight boxer, Grant became inadvertently entangled in the criminal underworld and developed a costumed identity to clear his name. Modern portrayals of Wildcat show him to be a rowdy tough guy with a streak of male chauvinism, leading to frequent clashes with the relatively progressive Power Girl, as well as exploring some of the character's insecurities. Meanwhile, a magical 'nine lives' spell has explained his vitality at an old age. Like many older JSA members, he's been a mentor to younger heroes, particularly Batman and Black Canary.
