#1 Steve Austin

Aside from the November 1997 Montreal Screwjob, where neither Shawn Michaels or Bret Hart wanted to lose against the other, the most famous example of somebody refusing to be defeated in a match came in 2002 when Steve Austin walked out of WWE.
“The Rattlesnake” was frustrated with his booking at the time and was told before a June episode of Monday Night Raw that, with no storyline build-up, he would be losing against newcomer Brock Lesnar in a King of the Ring qualifying match.

Austin has recalled the famous day several times over the years, and admitted on his Steve Austin Show podcast in 2015 that his walkout was “career suicide” and “a bad part of my life that I handled in a horrible fashion”.
Eight months later, the WWE Hall of Famer returned to the company to have one final high-profile match against The Rock in the main event of WrestleMania XIX.
