#2 The Ultimate Warrior
The Ultimate Warrior made his WWE debut in 1987 shortly after Demolition did. However, he was not a knock off of a different wrestling gimmick, but rather a continuation of a character called the Dingo Warrior. Vince McMahon loved the look of the Dingo Warrior, but changed the name to Ultimate. It was a great decision that increased Jim Hellwig's marketability.
The Ultimate Warrior was never a technical wrestling master. Instead, he overwhelmed his opponents with power moves, but the crowd loved him. Warrior's charisma was such that he is the only man in history to hold both the Intercontinental and World Heavyweight Championship in history.
The Ultimate Warrior spent some time on the outs with WWE management, but eventually was accepted back for a Hall of Fame induction shortly before his death from heart complications. While the Warrior will never be known as a great technical wrestler, he is still loved by millions of fans around the world.
