1. CM Punk As John Cena's Gangster - WrestleMania XXII
When you see the heights CM Punk got to in the WWE, and the way he left the company, it's hard to fathom that he was once an extra during one of John Cena's elaborate entrances. The Straight Edge Superstar played a gangster during Cena's entrance at WrestleMania XXII in 2006.
It's standard practice for developmental talent to be used as security guards on Raw for example, but very few find themselves as part of the WrestleMania main even on their unofficial debut. Neither of them could have imagined how big their 2011 rivalry would have become in the build up to this match, which Cena won of course by defeating Triple H.
