Ranking Wrestling's Most Shocking Surprise Every Year 1990-2020
12. 2009 - CM Punk Turns Heel

Punk had won and lost the World Championship from and to the 'Charismatic Enigma' over the summer of 2009, but Punk's switch to the dark side got him the gold for good at SummerSlam and eventually brought about the brilliance of brutality of the Straight Edge Society.
