#1. 'Stone Cold' Steve Austin vs Hulk Hogan
It's not a secret that the Vince McMahon had originally planned Hulk Hogan vs Stone Cold Steve Austin for WrestleMania 18. Austin flat out refused to compete against Hogan. It was reported that Austin wasn't thrilled with how Hogan had treated him back in WCW during the mid-90s. Apparently, Austin was about to get a push, but Hogan refused to feud with him. Austin returned the favor in 2002, and we never got the dream match.

In 2005, on the Homecoming episode of Raw, Hogan teased the match to the fans.
What would all these Hulkamaniacs do, if Hulk Hogan climbed in the ring, with that rattlesnake, 'Stone Cold' Steve Austin?
Months later, Austin teased the match while he was inducting Bret "The Hitman" Hart into the WWE Hall of Fame. The camera panned to Hogan, who was visibly upset. 13 years have passed since then, and it's safe to say now that we'll never witness these two legends take on each other.
