Ailín Pérez

Early Life and Background

Ailin Luciana Perez, nicknamed “Fiona,” was born in 1994 in Buenos Aires, Argentina, growing up in South America’s most cosmopolitan city. Her introduction to combat sports came early through Sanda and Kung Fu training, which she began at age 12. Unlike fighters whose formative martial arts experience was wrestling or traditional boxing, Perez’s early foundation was rooted in Chinese martial arts traditions. She demonstrated immediate aptitude for Sanda—Chinese kickboxing—and rose through the amateur ranks with focus and dedication. Her commitment to Kung Fu earned her a red belt, representing high-level proficiency in a discipline that requires both technical mastery and philosophical understanding. Her transition to Brazilian jiu-jitsu came later, and she has developed to purple belt level, indicating solid grappling credentials without elite-level BJJ specialization.

MMA Debut and Rise to UFC

Perez’s professional MMA career began in 2018, when she emerged as a legitimate competitor in South American women’s MMA. She distinguished herself through multiple championship achievements, becoming a two-time South American Sanda Champion and a two-time South American MMA Bantamweight Champion. These double achievements—both in traditional Sanda and in mixed martial arts—demonstrated her versatility and her dominance within the South American female fighting scene. In August 2021, she captured the Samurai Fight House bantamweight title, a significant regional championship that elevated her profile. Her professional record of 12-2 demonstrates consistent success and a high winning percentage. The UFC eventually brought Perez into the promotion, where she has competed at the highest professional level. Most recently, at UFC 311, she defeated Karol Rosa via unanimous decision, proving she can defeat quality UFC opposition at the world’s highest level.

Fighting Style and Attributes

Perez fights primarily as a striker, with her Sanda and Kung Fu background providing her with superior striking angles, footwork, and hand positioning compared to typical bantamweight opponents. Her four knockout victories suggest she can generate sufficient power to finish opponents through striking. Her two submissions indicate some grappling capability, though she is not primarily a submission specialist. Her purple belt in BJJ suggests solid technical knowledge of submissions and positions without the elite-level grappling credentials of a black belt. Perez’s primary fighting approach likely revolves around establishing Sanda striking range, using superior footwork and angles to land combinations, and avoiding being taken down into positions where her grappling disadvantages become apparent.

Ailin “Fiona” Perez brings a unique Sanda and Kung Fu striking background to the UFC women’s bantamweight division, an unusual and potentially advantageous distinction from fighters built on boxing or traditional kickboxing foundations. As a single mother of an eight-year-old son, Perez balances family responsibilities with her pursuit of elite-level competition—a reality that adds depth and perspective to her fighting career beyond the octagon.
