Now his gimmick was fully established. A true crazy heel, he acted like a wild man in the ring, tearing up the turnbuckle with his teeth and using the stuffing as a weapon as well as sticking out his green tongue. The Animal had a stooped posture and a hairless head, but a thick mat of fur on his back; wrestling broadcasters often speculated that The Animal was indeed "the missing link." At best, The Animal could occasionally manage to utter a word or two during interviews with one of them usually being "Duh-da-dahh" or "YOU! YOU go!".
Steele eventually became one of the more beloved wrestlers of the early "WrestleMania" era of the mid-1980s. He turned face during Saturday Night's Main Event when his partners in a six-man match, Nikolai Volkoff and the Iron Sheik, abandoned him to their opponents, Ricky Steamboat and the U.S. Express (Barry Windham and Mike Rotunda), leading to Steele being taken under the wing of the Express' manager, Capt. Lou Albano. His most famous feud was in 1986 against "Macho Man" Randy Savage, after Steele developed a crush on Savage's valet, Miss Elizabeth. The feud was meant to last only a couple of months (and end with Steele being disappointed), but it proved so popular with fans that it continued well into 1987. In 1988, Steele began carrying a stuffed animal named "Mine" to the ring, He participated in the Wrestlemania IV Battle Royal, but was outside the ring the whole time. Late in 1989 Steele retired due to Crohn's disease. Though he left the WWF without any WWF championships behind him, he left a fan favorite. A decade later, Steele came out of his retirement briefly.
In 1999, during the WWF's "Attitude Era", George Steele returned as part of The Oddities.
George Steele appeared on Monday Night Raw on November 15, 2010. He made a guest appearance during the Kofi Kingston vs. David Otunga match.
