Fergal Devitt (born 25 July 1981) is an Irish professional wrestler signed to WWE, where he performs on the Raw brand under the ring name Finn Bálor.
Devitt is widely known for his tenure with New Japan Pro Wrestling (NJPW) as Prince Devitt, where he is a three-time IWGP Junior Heavyweight Champion and six-time IWGP Junior Heavyweight Tag Team Champion, having held the title twice with Minoru and four times with Ryusuke Taguchi. He is also a two-time winner of the Best of the Super Juniors tournament, having won in 2010 and 2013, and was a founding member of the Bullet Club stable. Through NJPW's working relationship with Mexican promotion Consejo Mundial de Lucha Libre (CMLL), Devitt also wrestled there, becoming a one-time NWA World Historic Middleweight Champion. He also wrestled for numerous independent promotions, becoming a one-time ICW Zero-G Champion, one-time RPW British Cruiserweight Champion, and a two-time NWA British Commonwealth Heavyweight Champion.
After signing with WWE's development territory NXT and adopting his current ring name, Bálor became a one-time NXT Champion, with his reign being the longest in the title's history at 292 days. Shortly after arriving on the main roster, Bálor became the first wrestler in WWE history to win a world title in their pay-per-view debut, as well as becoming the quickest wrestler in WWE history to win a world championship at 27 days following his main roster debut by becoming the inaugural WWE Universal Champion. However, he relinquished the championship a day later due to suffering a legitimate shoulder injury during the title match.
