Regina Tarin bio
Personal background
Regina Tarin, who competes in the UFC flyweight division as “Kill Bill,” is an undefeated Mexican prospect born on October 19, 2004, and raised in Mexico City. Listed on official records under the full name Regina Tarin Malpica Rivera, she emerged from Mexico's growing women's MMA scene as a finisher built around sharp, aggressive boxing and an opportunistic grappling game. Fighting out of Bonebreakers MMA, the 5'7" flyweight carries a 66-inch reach that lets her control range behind her striking, and she has paired that frame with the kind of fast, violent finishes that earned her the “Kill Bill” nickname. Beyond the cage, she drew attention in early 2026 when she tried out for WWE at its Orlando Performance Center, impressing trainers before choosing to keep her focus on mixed martial arts.
Path to the UFC
Tarin turned professional in 2023 and built her entire record on the regional circuit before the UFC came calling, fighting for promotions including Budo Sento Championship and Combate Global. She debuted with a first-round rear-naked-choke submission of Citlalli Alcantar at Budo Sento Championship 19 in December 2023, then went the distance for a unanimous-decision win over Andrea Garcia at Budo Sento Championship 21. Moving onto bigger regional stages, she submitted Fernanda Marrufo by rear-naked choke in the first round and stopped the more experienced Gisela Luna by first-round TKO, signaling that her finishing power translated against tougher opposition.
Building an undefeated record
Tarin kept the knockouts and stoppages coming as her competition improved. She halted Luisa Cifuentes by fourth-round TKO at Budo Sento Championship 25 in September 2024, then returned to Combate Global to stop veteran Kaytlin Neil by second-round TKO in June 2025. A first-round knockout of Yurivia Jimenez at TNX 1125 in November 2025 ran her record to a perfect 8-0 and put her firmly on the UFC's radar as one of Mexico's most promising young finishers.
UFC debut
Tarin's UFC arrival came under the toughest possible circumstances. She stepped in on just three days' notice for her hometown card at UFC Fight Night in Mexico City in February 2026, facing the experienced Ernesta Kareckaite (6-1-1). Rather than wilt, Tarin leaned on her boxing through a competitive three-round scrap and took the unanimous decision, extending her unbeaten run to 8-0 and announcing herself on the sport's biggest stage in front of a home crowd.
Fighting style
Tarin is a finisher first, with six of her eight wins coming inside the distance and a 75% finish rate that reflects genuine stopping power. Her four knockouts and two submissions show a fighter who can end things on the feet or on the mat, but boxing is the foundation – crisp, pressure-based combinations that she uses to break opponents down. Her two decision wins, including the short-notice UFC debut, also prove she can manage a full fight when the finish does not come, a maturity that belies her age. With a clean, loss-free record, the main questions ahead concern how her grappling and cardio hold up against the deeper, more rounded competition that comes with UFC matchmaking.
Career highlights
- Undefeated through eight pro fights — Tarin reached the UFC with a spotless 8-0 record and a 75% finish rate, one of the most promising young records in Mexican women's MMA.
- Winning UFC debut on three days' notice — she beat Ernesta Kareckaite by unanimous decision in her hometown of Mexico City despite minimal preparation.
- Regional finishing run — six stoppages across Budo Sento Championship, Combate Global and TNX, including knockouts of seasoned opponents Gisela Luna and Kaytlin Neil, built her reputation as “Kill Bill.”
