Phillip Jack Brooks (born October 26, 1978), better known by the ring name CM Punk, is an American mixed martial artist, comic book writer and retired professional wrestler. He is currently signed to both the Ultimate Fighting Championship (UFC), where he competes in the welterweight division, and to Cage Fury Fighting Championships (CFFC), where he works as a commentator. He is perhaps best known for his time in WWE, where he is recognized as the sixth longest reigning WWE Champion of all-time.
Brooks began his professional wrestling career on the American independent circuit, primarily with Ring of Honor (ROH) until 2005, when he signed with World Wrestling Entertainment (WWE). During his 15-year career, Brooks won the WWE Championship twice, WWE's World Heavyweight Championship three times, and the ECW and ROH World Championships once each. By winning WWE's World Tag Team Championship (with Kofi Kingston) and Intercontinental Championship, he became WWE's 19th Triple Crown Champion and the fastest to achieve this feat, in 203 days. He was voted WWE Superstar of the Year at the 2011 Slammy Awards, and Wrestler of the Year in 2011 and 2012 by readers of Pro Wrestling Illustrated.
Brooks used the CM Punk moniker his entire career, and consistently portrayed the character of an outspoken, sharp-tongued, anti-establishment, straight edge iconoclast. Most of the straight edge principles he portrayed, such as not drinking alcohol or not taking recreational drugs, are his real life views. Depending on his alignment as a hero or villain, he emphasized different aspects of the straight edge culture to garner the desired audience reaction.
After becoming disgruntled in WWE, Punk retired from professional wrestling in 2014. He pursued a career in mixed martial arts and was signed by the UFC in December of that year. His first professional fight took place on September 10, 2016, at UFC 203 against Mickey Gall, where he was defeated via submission in the first round. He lost his second bout to Mike Jackson via unanimous decision on June 9, 2018, at UFC 225.
