Phillip Jack Brooks (born October 26, 1978), better known by his ring name CM Punk, is an American professional wrestler and actor. As of November 2023, he is signed to WWE, where he performs on the Raw brand and is the World Heavyweight Champion in his record-tying second reign. Regarded as one of the greatest professional wrestlers of all time, he is known for his outspoken and confrontational straight edge persona, which is based on his real-life experiences. His 434-day reign as WWE Champion is the 10th-longest world title reign in the company's history.

Brooks began his wrestling career on the independent circuit in 1997. He signed with Ring of Honor (ROH) in 2002, where he won the ROH World Championship once and was one of the inaugural inductees into the ROH Hall of Fame in 2022. Brooks signed with WWE in 2005 and won the WWE Championship twice, the now-defunct World Heavyweight Championship three times, the ECW Championship, the Intercontinental Championship and the World Tag Team Championship once each. Brooks also won the Money in the Bank ladder match in 2008 and 2009 (making him its only back-to-back winner), was named Superstar of the Year at the 2011 Slammy Awards, and was voted PWI Wrestler of the Year in 2011 and 2012. After acrimoniously leaving WWE in 2014, Brooks retired from wrestling but returned in 2021 when he joined All Elite Wrestling (AEW), where he won the AEW World Championship twice. Brooks was fired in September 2023 after backstage controversies and returned to WWE two months later, where he has since headlined multiple major pay-per-view and livestreaming events, including WrestleMania 41 – Night 1, and won the newer version of the World Heavyweight Championship twice.

Donald Jacob Hager Jr. (born March 24, 1982) is an American retired professional wrestler, amateur wrestler and mixed martial artist. He is best known for his tenures in WWE as Jack Swagger and in All Elite Wrestling (AEW) as Jake Hager. As a mixed martial artist, he was signed to Bellator MMA and competed in the heavyweight division.

Hager attended the University of Oklahoma as a two-sport athlete, participating in both football and wrestling. He switched to wrestling full-time in his sophomore year, and in 2006, set the record for most pins in a season with 30 as an All-American. Following a try-out, Hager signed a WWE contract in mid 2006 where he performed as Jack Swagger. During his time with WWE, he became a two-time world champion, having held the WWE's World Heavyweight Championship and the ECW Championship once each and a one-time United States Champion. He left the company in 2017 after he decided to pursue a professional mixed martial arts (MMA) career.
