1. CM Punk
CM Punk was a young pretender in ROH in the year 2003 when he had a high profile feud with Raven which elevated him to the top of the promotion. ROH had a working relationship with TNA that time and Punk showed his skills there too.
His TNA stint was as a disciple of Raven – alongside future WWE womens’ champ Mickie James - and in 2004, he would turn on Raven and align with James Mitchell. In a historically significant epic blunder,TNA management felt that Punk was not connecting with the fans a villain and pulled the plug on his feud with Raven.
A top AEW star just called one of his colleagues 'spoiled' and 'narcissistic' HERE.
Punk would return to ROH – the Indie Summer of Punk would take shape and he would promptly move on to the WWE, becoming one of the most significant superstars of the next decade.
