CM Punk rolled back the years last night at WWE/AAA Worlds Collide, coming out to his SES TitanTron and his old theme song This Fire Burns by Killswitch Engage.

Sporting a black lucha mask and a serape featuring the masks of several luchador stars, the former WWE champion blew the roof off the Allstate Arena when he entered, with the fans singing along to his first WWE iconic theme song.

Punk teamed up with Hall of Famer Rey Mysterio and AAA Mega champion El Grande Americano to face Dominik Mysterio, JD McDonagh, and Omos in a six-man tag team match in the main event.

Worlds Collide will air on tape delay on Wednesday, September 30 exclusively on YouTube.
