Brock Edward Lesnar ( ; born July 12, 1977) is an American professional wrestler, former mixed martial artist (MMA), amateur wrestler, and professional American football player who holds both American and Canadian citizenship. He is currently signed to the professional wrestling promotion WWE, where in storyline, he is a "free agent", allowing him to appear on both the Raw and SmackDown brands. Often regarded as one of the most prolific athletes in the world, Lesnar is the only person to have won all of the primary heavyweight championships in WWE, Ultimate Fighting Championship (UFC), New Japan Pro-Wrestling (NJPW), and the National Collegiate Athletic Association (NCAA). Lesnar competed in collegiate wrestling for the University of Minnesota, winning the NCAA Division I national championship in 2000. He soon signed with the World Wrestling Federation (WWF, renamed WWE in 2002), rising to industry prominence in 2002 by winning the WWE Championship at age 25, setting the record for the youngest performer to win the championship. In 2004, Lesnar departed WWE to join the Minnesota Vikings of the National Football League (NFL), but was cut from the team during pre-season. He returned to pro-wrestling and signed with NJPW in 2005 where he won the IWGP Heavyweight Championship. Years later in 2012, he re-signed with WWE; his 504-day first reign with the WWE Universal Championship is the seventh-longest world championship reign in the promotion's history and he holds the record for most reigns as Universal Champion at three. He also won the Royal Rumble match twice (2003 and 2022), the Money in the Bank ladder match (2019), the King of the Ring tournament (2002), and has headlined several pay-per-view events, including WWE's flagship event WrestleMania five times (XIX, 31, 34, 36, and 38); in addition, he also ended The Undertaker's undefeated WrestleMania streak in 2014. Lesnar began an MMA career in 2007, and signed with the UFC in 2008. He quickly won the UFC Heavyweight Championship, but was sidelined with diverticulitis in 2009. On his return in 2010, Lesnar defeated Interim UFC Heavyweight Champion Shane Carwin to unify the heavyweight championships and become the undisputed UFC Heavyweight Champion. After a set of losses and further struggles with diverticulitis, Lesnar retired from MMA in 2011. He returned at UFC 200 in 2016 to defeat Mark Hunt, but his victory was overturned to a no-contest after he tested positive for clomiphene, a banned substance on UFC's anti-doping
