He is best known for his time in WWE, where he was a two-time WWE Champion, including a 434-day reign from November 20, 2011, to January 27, 2013, that is recognized by WWE as the sixth longest 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).
Throughout his career, he won several championships including the WWE Championship twice, WWE's World Heavyweight Championship three times, and the ECW and ROH World Championships once each.
After retiring from professional wrestling in 2014, Punk 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 lost via submission in the first round.
Most of the straight edge principles he portrayed, such as not drinking alcohol or not taking recreational drugs, are his real life views.
In WWE, he was also a one-time World Tag Team Champion (with Kofi Kingston), and one-time Intercontinental Champion, making him the 19th WWE Triple Crown Champion and the fastest man in WWE history to achieve this feat, doing so in 203 days.
In addition, he was the 2011 WWE Superstar of the Year and the first two-time Money in the Bank winner.
For weeks, Punk teased the ROH locker room and the ROH fans as well as mocking the championship he possessed, going so far as to sign his WWE contract on it.
During the storyline, referred to by ROH as the "Summer of Punk", Mick Foley made several ROH appearances, attempting to convince Punk to do the right thing and defend the title on his way out.

It's something we're more susceptible to and I was diagnosed with bipolar disorder around 19 [or] 20 [years of age]." Additionally, AJ divulged that Punk knew about her mental condition prior to dating, so it never came as a surprise.
