Wildcat

Created by Bill Finger and Irwin Hasen.
First appeared in Sensation Comics #1 (January 1942; Both Wonder Woman and Mister Terrific also debuted in this issue).

Ted Grant's father, Henry Grant, vowed on his baby son's crib that the child would not grow up afraid of life, and so he encouraged his son in sports and paid for coaching that would have continued into the young man's college days, except that both he and his wife died. Orphaned in the days of the Great Depression, Ted Grant found himself unemployed in the big city. One night he saved "Socker" Smith, the heavyweight boxing champion, from a mugging. "Socker" took Ted under his wing, and soon Ted became a heavyweight boxing champion in his own right. He also unknowingly became tangled in his manager's sinister plans. As a result, his mentor "Socker" Smith was killed by a boxing glove loaded with a poison needle by Grant's managers Flint and Skinner. The dose was only intended to slow Smith, but the duo misjudged the potency. When Grant was arrested for the crime, Flint and Skinner, afraid that he might know what had really happened, arranged a hit on the young fighter. Grant survived and escaped, but the policemen with him were both killed. He became a fugitive and came upon a child who had been robbed of his Green Lantern comic. The kid, describing the mystery-man Green Lantern, inspired Grant to create a costume of a large black cat. He took the name of Wildcat and vowed to clear his name. He brought Flint and Skinner to justice; the criminals were forced to confess, and the results were not only that Grant's name was cleared but also that Smith too received his justice. After exonerating himself and obtaining justice for his mentor, Grant, using the identity of Wildcat, continued to fight against crime.

Grant is a normal human who was, at some unspecified point, magically given nine lives. He remains at the peak of human condition due to extensive workouts that consist of intensive exercise. He is a world-class boxer who trained Batman, Black Canary, and even Superman in the art. He was trained to fighting condition by ex-boxer Joe Morgan (the same man who trained Grant's fellow mystery men, Atom and the Guardian).
