In professional wrestling, Punk is a six-time world champion having won the ROH World Championship, ECW Championship, and WWE Championship each once, and the World Heavyweight Championship three times, making him the second wrestler (after Kane) to have held all three of WWE's World titles.
In addition to these championships Punk has also won the World Tag Team Championship (with Kofi Kingston), and the WWE Intercontinental Championship making him the nineteenth WWE Triple Crown Champion. Between WWE and ROH (where he is also a two time tag team champion), Punk has won a total of ten championships. He was also the winner of the 2008 and 2009 Money in the Bank ladder matches, the only Superstar to win the match twice in a row.
Punk initially came to prominence through his career on the professional wrestling independent circuit, primarily as a member of the Ring of Honor (ROH) roster, where he won the ROH Tag Team Championship, ROH World Championship, and was the first head trainer of the ROH wrestling school. 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 the promotion.
Throughout his career, Punk has consistently used the gimmick of being straight edge, a lifestyle he follows in his actual day-to-day life. Depending on Punk's alignment as a crowd favorite or villain, he emphasizes different aspects of the culture to encourage the desired audience reaction.
