At the same time, Punk joined the wrestling promotion NWA Total Nonstop Action (TNA), in which he was paired with Julio Dinero as members of Raven's TNA alliance The Gathering.
Punk started climbing the ranks of ROH, including coming in second at the Second Anniversary Show during the tournament to crown the first ROH Pure Champion, losing to A. Styles in the finals and winning the ROH Tag Team Championship twice with Colt Cabana as the Second City Saints.
In 2005, Punk signed a contract with WWE and was sent to its developmental promotion, Ohio Valley Wrestling (OVW), where he won every championship available in that promotion.
On June 24, 2006, Punk made his WWE television debut, performing in ECW, which was then a branch of WWE.
Throughout his career, Punk has consistently used the gimmick of being an outspoken, sharp-tongued, and straight edge iconoclast.
Between WWE and Ring of Honor (where he is a two-time World Tag Team Champion), Punk has won a total of 11 championships.
Punk's first venture into wrestling was a stint in a backyard wrestling federation called the Lunatic Wrestling Federation with his friends and brother Mike Brooks in the mid-late 1990s.
He first started using the ring name CM Punk when he was put into a tag team named the Chick Magnets with CM Venom after another performer skipped out on the card.
There, he was the first head trainer of the ROH wrestling school.
Also while competing in ROH, Punk won both the company's championships.
