Demetrious Johnson, known as “Mighty Mouse,” is an American former professional mixed martial artist from Washington state, widely regarded as the greatest flyweight in the sport's history. Fighting out of Parkland, Washington, where he had been a decorated high-school wrestler, Johnson became the UFC's inaugural flyweight champion on September 22, 2012, defeating Joseph Benavidez by split decision at UFC 152 in Toronto. He then defended the title eleven consecutive times, a UFC record that surpassed Anderson Silva's ten, in a reign lasting 2,142 days, the longest in UFC flyweight history, before losing a split decision to Henry Cejudo in August 2018. In an unprecedented trade between major promotions, Johnson moved to ONE Championship, where he won the ONE Flyweight World Grand Prix and the ONE flyweight championship. He announced his retirement in 2024 with a professional record of 25 wins, four losses and one draw, and in 2026 he was inducted into the UFC Hall of Fame's Modern Wing.

Notes
Sports Encyclopedia roster CTL-SPE-0218. Firsts disposition: Johnson is carried as the UFC's INAUGURAL flyweight champion (2012) — a first of office, not of identity — supported by the UFC and ESPN; his 11 consecutive title defenses are a UFC record per the UFC and ESPN. No identity-based “first” is claimed. FLAG: UFC.com's Hall of Fame article misstates that Johnson “retired on May 5, 2023”; May 5, 2023 was his final bout (a successful ONE title defense), and ESPN and Sportsnet both record the retirement announcement in 2024 — the description follows ESPN/Sportsnet. Curator's Judgment (DRAFT): Johnson's reign is the statistical summit of the lighter weight classes, achieved in the division he effectively created as a draw. The photograph cleared for this record, from his professional debut card in 2009, bookends the reign it began. Photo: CLEARED — Demetrious Johnson.jpg, CC BY 2.0.
