#2 WWE Star The Rock
Dubbed as WWE's first 3rd generation star, Dwayne Johnson entered the company with a big weight on his shoulders. Making his debut as "Rocky Maivia" Johnson straight away got a big push from the officials.
Unfortunately, both Johnson and the fans weren't quite ready for such to happen. The crowd hated Johnson and his babyface character so much that the chants of "Die, Rocky, Die" and "Rocky Sucks" were heard every time he entered the arena.
Johnson's career could've ended if he had continued to portray the same stale "Blue Chipper" character. However, a blessing came in disguise for him when he suffered a legitimate leg injury. After fully recovering, he made his return as a heel.
Johnson started referring to himself in the third person as "The Rock" and regularly insulted the audience, WWE performers, and interviewers in his promos. He also joined forces with The Nation of Domination to bring out his bad side.
This change in character brought the best out of Johnson and skyrocketed his career. It also helped the fans realize the star's potential that they had been neglecting for so long. Nonetheless, Johnson's heel turn helped him reach the pinnacle of his career. It also made him one of the greatest stars in WWE history and helped launch his career in Hollywood.
