10 Best CM Punk Matches In WWE

8. Vs. Rey Mysterio - Over The Limit 2010

Punk's messianic personality change as the leader of the Straight Edge Society in 2010 was an interesting and well-timed one. 

It transformed him into one of WWE's most intriguing characters and strongest heels, with Rey Mysterio perfectly positioned as his babyface adversary. 

The pair had some cracking matches at WrestleMania XXVI and the following month at Extreme Rules (as well as on television), but saved the best for last with their big blowoff at Over the Limit. 

The juicy stipulation - if Rey lost he would have to pledge allegiance to the Straight Edge Society, while Punk's hair would be shaved off if he failed to win - certainly added to the drama, as too did WWE doctors stopping the bout in its early stages to check on a cut to Punk's head. 

He angrily shook it off and ramped up the intensity with some fierce kicks and other high impact moves. Rey, ever resilient, kept finding new ways to come back and, following a series of gripping nearfalls, rolled up a cocky Punk for the three. 

In the post-match scene the Society (who had been banned from ringside during the match) ran in and attempted to prevent their saviour's haircut, but were chased off by Kane and Mysterio did his best Brutus Beefcake.
