6 WWE Superstars you didn't know CM Punk wrestled  

#3 Raven

Nevermore

If anything, at the time, this was considered one of the best feuds in wrestling outside of WWE. The feud was impressive at the time. The story was quite simple. CM Punk was a straight-edge star who had a terrible upbringing because of his alcoholic father. Punk, who was the heel, saw Raven, as his father's equivalent engaging in a lifestyle that was disgraceful.

CM Punk and Raven had a series of matches that last almost a year in 2003 and was considered the best storyline ROH had going at the time. The matches were brutal and were a series of no-disqualification matches where both wrestlers brawled over a course of time.

Punk's time with Raven in the ring molded him into a better wrestler and gave him an education in match promos and in-ring psychology. During an interview, Raven reflected on this.

"I never realized I helped him that much. Maybe he was listening when I thought he was arguing with me. I thought he would've looked back with less than fondness on me because we butted heads quite a bit, but I'm glad he didn't."

CM Punk's time before WWE was impressive and it helped him go a long way into making him a WWE Superstar.
