Brock Edward Lesnar (July 12, 1977), better known by his ring name Brock Lesnar, a American professional wrestler and former mixed martial artist, amateur wrestler, and professional American football player who performed in WWE.
After his successful amateur wrestling career at Bismarck State College and the University of Minnesota, Lesnar signed with WWE (then the World Wrestling Federation) in 2000. He was assigned to its developmental promotion Ohio Valley Wrestling (OVW), where he was a three-time OVW Southern Tag Team Champion with Shelton Benjamin. After debuting on WWE's main roster in 2002, he won the WWE Championship on three separate occasions with victories over The Rock and Kurt Angle (twice). Lesnar won the then WWE Undisputed Championship five months after his main roster debut at the age of 25, becoming the youngest champion in the title's history. He was also the 2002 King of the Ring and the 2003 Royal Rumble winner, making him the youngest King of the Ring and Royal Rumble winner as well. Following his match with Goldberg at WrestleMania XX, Lesnar left the WWE and pursued a career in the National Football League . He was named a defensive tackle for the Minnesota Vikings, but was cut prior to the start of the 2004–2005 season. In 2005, Lesnar returned to professional wrestling and signed with New Japan Pro-Wrestling, where he won the IWGP Heavyweight Championship in his first match. After a contractual dispute with NJPW, he also wrestled as IWGP Heavyweight Champion in the Inoki Genome Federation.
In April 2012, Lesnar once again returned to professional wrestling, rejoining WWE after an eight-year hiatus. Two years later, at WrestleMania XXX, Lesnar defeated The Undertaker to end his undefeated streak at WrestleMania. He achieved world champion status twice since his return, having won the then WWE World Heavyweight Championship in 2014 and the WWE Universal Championship in 2017. Lesnar has been managed by Paul Heyman throughout the majority of his professional wrestling career.
Lesnar is a five-time world champion in WWE, a one-time heavyweight champion in the UFC, a one-time heavyweight champion in NJPW, and a one-time heavyweight wrestling champion in the NCAA, the only person in history to win a championship in each of those organizations. He has headlined numerous pay-per-view events for both the WWE and UFC, including WrestleMania XIX, WrestleMania 31, UFC 100 and UFC 116. In 2015, an ESPN.com article referred to Lesnar as "the most accomplished athlete in professional wrestling history"
