#4 Curt Hennig
After eight years with the WWE, Mr. Perfect went to WCW. Since the WWE trademarked Mr. Perfect, he just went by his real name Curt Hennig. He would originally join The Four Horsemen replacing Arn Anderson who retired, but turned on them and join the nWo.
The turn on the Horsemen occurred in the WarGames match at Fall Brawl in 1997. Hennig showed up at the arena with his arm in a sling, but it was all a ruse and he attacked the Horsemen making the WarGames match 5-on-3.
Hennig joined Kevin Nash, Buff Bagwell, Syxx (X-Pac), and Konnan as they destroyed Ric Flair, Steve McMichael, and Chris Benoit. The match is famous for Hennig repeatedly slamming Flair's head on the cage door.
