He was the foe of the original Green Lantern as well as Wildcat. He was first known as Crusher Crock, a frustrated athlete who turns to a life of crime. He was a member of different incarnations of the Injustice Society. He helped capture the JSA using an exploding ball, after which they were hypnotized and then during the Patriotic Crimes he steals Old Ironside. He teams up with (and later marries) the Golden Age villainess Huntress. Later they have a child named Artemis Crock who became the third Tigress. In his later years he spent time behind bars but at least on one occasion was broken out of prison by his daughter - then a member of Injustice Unlimited. Following his death, his body was cloned by a secret organization called the Council for their enforcers (they had previously used Manhunter).
