2. Hulk Hogan
As a twelve time champion of the world, there is no denying the Hulkster's place in wrestling history, but he has shown a tremendous ego on his way through WWF, WCW and TNA. Seizing on his initial fame from starring as Thunderlips in Rocky 3, Hulk had commercial appeal that made him an almost invincible superman in his WWF peak years. Because of his ability to sell arenas out and push merchandise, Hulk could basically do whatever he wanted and Vince McMahon would be fine with it. Hogan was WWF champion for four years, pinning the likes of Andre the Giant along the way, and along the way, his ego got bigger and bigger, to the point that he still demanded to be the main man when business dropped off in the early 90's. Hogan would refuse to lose, and scoffed at the idea of losing to the likes of Bret Hart. Eventually, he would jump ship to WCW and after the defection, he continued to show the same selfishness, demanding that be booked as world champion, and looked to steal the thunder from anyone he was booked alongside. Hogan also seen to it that Eric Bischoff signed up all of his old friends, such as Brutus Beefcake, who had nothing to offer WCW but who Hulk clearly wanted to hang out with. At times, WCW resembled the Hulk Hogan show, although in fairness he did put Bill Goldberg over in a famous bout, which WCW put on television. Still, Hogan more or less never lost matches: he was a man who had to win. He returned to WWE in 2002, and characteristically refused to put Brock Lesnar over. A few years later Hogan again refused to put younger potential over, and he pinned Randy Orton at Summerslam 2006. There was also a dispute with Shawn Michaels, who had put Hogan over at Summerslam 2005 - but when it came time for Hogan to return the favour, he refused.
