#3 Hulk Hogan
Hulk Hogan signed with WCW in 1994, and won the WCW World title in his debut match against Ric Flair. In what many have dubbed as the greatest heel turn of all time, Hogan became a villain at WCW Bash at the Beach 1996, forming the nWo with Scott Hall and Kevin Nash.
Hogan's waning career got an overhaul after the heel turn and WCW went on to defeat WWE in the weekly rating war for 83 straight weeks.

When Hogan returned to WWE in 2002, he faced The Rock in a dream match at WrestleMania 18. He was still getting some of the biggest reactions at the time, which forced WWE to make him WWE Champion.
Hogan defeated Triple H at Backlash 2002 to win his sixth and final WWE title. He went on to feud with Vince McMahon, Shawn Michaels, and Randy Orton in the coming years, and was inducted into the WWE Hall of Fame in 2005.
