#1 The Rock

The Rock was something completely different from the rest of the Superstars in the 1990s. There were a few superstars here and there that were still good on the mic.
But once Dwayne Johnson transformed from Rocky Maivia to the Rock, he changed what it meant to be masterful on the microphone.
He found his beginnings in the company a little harder, starting out as a smiling babyface like Apollo Crews is today. Once the crowd started to turn against him, he turned heel and would berate the audience nightly.
Since he was so transcendent on the mic, Mr. McMahon saw dollar signs in what this young star would be capable of as a major player in the WWF.
The Rock had tenures as a member of the Nation of Domination, a tag team partner of Mick Foley and a member of the Corporation.
His feuds with Mick Foley and Stone Cold defined the latter part of the decade and helped transition the company into the new millennium.
Even though I wasn't a huge and still am not a huge fan of his, it's hard to argue against his spot in history and the fact that he was one of the most impactful and important superstars of the 1990s.
