You wanna talk about disappointing? Look no further than the Straight Edge Messiah, CM Punk. 2010 has been pure hell for CM Punk. Last year Punk was on top of the world. He had won his second straight MITB Ladder match at Wrestlemania.
Drafted to Smackdown and entering a feud with Umaga, he became one of the few men to defeat him during his WWE Tenure. Punk was on a role. He had already been World Champion, and he had a sure fire Title Reign in his hands.
The Sky was the limit for Punk.
He surprisingly cashed in his MITB on Jeff Hardy. Both being faces at the time, most of his fans were upset over his decision. Slowly showing signs of a heel turn, Punk lost the World Title to Hardy at Night of Champions. He delivered a vicious beatdown on Hardy, cementing his heel status.
His mic skill had dramatically improved. With everyone aware of Hardy's impending departure, it was only a matter of time before he regained the World Title. He did just that at Summerslam last year. Immediately afterwards, he entered a feud with the Undertaker.
By this time, Punk was the most hated Superstar on the WWE Roster. We all knew Taker was going to reclaim the World Title. After a screwy lost to Punk at Breaking Point, Undertaker quickly dominated Punk at Hell in a Cell to win the World Title.
This started the downward spiral of CM Punk. He started the Straight Edge Society. Doomed from the start, the SES added Serena and Luke Gallows to the mix. He then entered a feud with Rey Mysterio, who he blamed for not winning the World title in the Elimination Chamber.
Rey destroyed Punk at Wrestlemania, leading to a rematch at Extreme Rules with Punk's hair on the line. With an assist from a masked assailant, Punk won the match. A third match between the two was scheduled at Bragging Rights. Rey bested Punk and his head was shaved bald.
Punk began to wear a mask similar to Rey Mysterio's, and his SES was beginning to fall apart. After losing a Fatal 4-Way, Punk entered a feud with Big Show. Show slowly destroyed the SES, as he unmasked Punk during a segment on Smackdown.
He defeated Mercury, Punk and Gallows in a handicap match at Summerslam. Serena was released, Mercury was out with an injury and Punk turned on Gallows. The SES was officially over.
Punk was reduced to beating jobbers like JTG on Smackdown. Big Show defeated Punk at Night of Champions ending their feud. Punk was slowly dropping to jobber status, being dominated by the Undertaker in two matches.
Now he's back on RAW, but I doubt if things begin to change for Punk.
