#1 The Rock
Before becoming The Rock, Dwayne Johnson was introduced to WWE fans as Rocky Maivia, the son of Rocky Johnson and a third-generation Superstar. The gimmick saw Maivia coming out in fancy attire and sporting a bad haircut, with a big smile on his face.
The always happy Maivia was too much for the rabid WWE fans who were getting tired of WWE still being stuck in the past.

Maivia began getting chants of "Die Rocky, die", and the gimmick was soon scrapped. Maivia soon became The Rock and the rest is history.
His feud against Stone Cold Steve Austin is widely regarded as being one of the greatest rivalries in the history of this business. The two legends were featured in big-stake matches at WrestleMania 15, 17, and 19, with two of them being WWE Title bouts.
