Early Life and Background
Miguel David Aceves Martínez was born on August 3, 1998, in Ecatepec de Morelos, State of Mexico. During his childhood, his family relocated to Mexico City because of local insecurity, where he spent his formative years. He is the younger brother of Melissa Martínez, who is also a professional mixed martial artist and remains a close training partner.
During his teenage years, Martinez discovered mixed martial arts and joined the Bonebreakers MMA Team alongside his older sister. He also pursued a rigorous academic path, eventually earning a medical degree from the National Autonomous University of Mexico. His dual commitment to medicine and fighting has earned him the Black Spartan Doctor moniker that now defines his public identity.
Path to MMA
Martinez began his professional career in 2016, fighting primarily in regional Mexican promotions as a bantamweight. He built a strong record through consistent performances and finishing ability, attracting attention from larger organizations. In 2018, he signed with Combate Americas, a Latin American-focused MMA promotion, marking his first major step onto an international stage.
His early years on the regional circuit were defined by knockout victories, establishing a reputation as a dangerous striker. He holds a black belt in karate and a black belt in kickboxing, while continuing to develop his ground game with a purple belt in Brazilian Jiu-Jitsu. These foundational skills paved the way for his championship opportunities in Combate Global.
David Martinez Career
Early Career (2016–2018)
Between 2016 and 2018, David Martinez competed across small Mexican promotions, racking up victories with his aggressive striking style. Working out of Bonebreakers MMA, he developed his knockout power and ringcraft under experienced coaches. His finishing rate quickly made him one of the most talked-about prospects in the regional scene.
By the time Combate Americas offered him a contract, Martinez had already established himself as a finisher with a developing all-around game. The move to a televised promotion gave him a platform to showcase his karate-based striking and his growing confidence against higher-level opposition.
Combate Global Breakthrough (2018–2024)
Martinez signed with Combate Americas in 2018, an organization later rebranded as Combate Global. He suffered the first defeat of his professional career on April 9, 2021, dropping a bout to Gianni Vázquez at Combate Global: Chairez vs. Monterroso. That loss would become the only blemish on his record.
When bantamweight champion Gustavo Lopez vacated the title, Combate Global organized a tournament to crown a new champion. Martinez defeated Alejandro González by first-round technical knockout in the quarterfinals on May 29, 2021, then outpointed Alan Cantú in the semifinals. In the final that same night, he faced Francisco Rivera and won the bantamweight championship with a knockout just 17 seconds into the second round.
Martinez went on to defend the title three times. He stopped Arturo Vergara via first-round TKO on May 27, 2022, and finished Axel Osuna by fourth-round TKO on October 7, 2022. He capped his Combate Global run with a fourth-round head-kick knockout of Jose Zarauz on May 28, 2023, before eventually parting ways with the promotion.

Martinez earned his UFC opportunity on Week 8 of Dana White’s Contender Series Season 8, where he faced Xavier Franklin on October 1, 2024.

He made his UFC debut on March 29, 2025, at UFC on ESPN 64, taking on Saimon Oliveira. Martinez won the fight in the first round with a combination of knees and punches, earning a Performance of the Night bonus in the process. He followed that up with a unanimous decision victory over Rob Font after a previously canceled booking against Carlos Vera was reshuffled.
Continuing his rise, Martinez faced Marlon Vera on February 28, 2026, at UFC Fight Night 268, and walked away with another unanimous decision win. As of mid-2026, he holds a professional record of 14 wins and one loss, with 10 of his victories coming by knockout. His climb up the bantamweight ladder has made him one of the division’s most exciting rising names.
