#3 The Rock
The Rock's first WWE gimmick of a generic babyface wasn't something the rabid WWE fans of the 90s wanted to see. He soon began getting booed on a regular basis, with chants of "Die Rocky, die" becoming a regular thing on weekly TV.
Maivia was soon repackaged and turned into a heel. He returned to WWE TV in August 1997 after taking time off due to injury. Vince McMahon had dropped Maivia's babyface gimmick, repackaging him into an arrogant and self-centered heel. Now dubbing himself as The Rock, he joined The Nation of Domination alongside Faarooq, D'Lo Brown, and Kama. He then began berating the fans for booing him.
The gimmick helped The Rock turn into one of the biggest Superstars of the Attitude Era and resulted in him bagging a string of WrestleMania main events, plus several WWE title reigns.
The Rock tweaked his gimmick when he returned in early 2003, after a short hiatus due to his Hollywood stint. The "Hollywood Rock" character is now widely regarded as one of the greatest heels of all time, even though it didn't last more than a few months.
