Early Career
Robbie Peralta’s martial arts journey began in Escondido, California, when he took up taekwondo at age five and trained until he was twelve. That solid striking base would later define his approach in mixed martial arts.
He made his professional MMA debut in March 2007 at MMA Xtreme 9 in Tijuana, where he lost by submission. Rather than derail his ambitions, that first setback motivated Peralta to refine his skills.
In the following months, he fought multiple times in Mexico and Central America, collecting three consecutive knockout wins in Honduras and earning a reputation for heavy hands and unyielding forward pressure.
By 2009, Peralta returned to California and began competing in Gladiator Challenge, a regional promotion that would be the launching pad for his rise. He captured the Flyweight Championship in April 2010 with a triangle choke submission and defended it before moving up to featherweight.
In December of that year, he claimed the Gladiator Challenge Featherweight title via first-round TKO, showcasing crisp combinations and sturdy defense. Two successful defenses later, Peralta entered 2011 with an 11-3 record and a two-division résumé.
His performances attracted attention from larger organizations due to his finish-rate-only twice out of his first fourteen wins went to decision.
Peralta’s streak in Gladiator Challenge and his mastery of stand-up led to a Strikeforce debut in April 2011 on the Diaz vs. Daley card in San Diego. There he upset veteran Hiroyuki Takaya by split decision, proving he could compete on a national stage. That victory cemented his transition into the major leagues and earned him a spot on the UFC roster later that year.
Throughout his early career, Peralta displayed an evolving blend of taekwondo footwork and raw punching power, often overwhelming opponents with sustained pressure. He built a foundation of resilience, learning to absorb takedown attempts and return fire, which would serve him as he climbed to the sport’s highest level.

Professional Career
Peralta debuted in the UFC in September 2011 at Fight Night: Shields vs. Ellenberger, earning a unanimous decision over Mike Lullo in New Orleans. He followed up by knocking out Jason Young in Nottingham in a swift 23-second performance, showcasing why he was seen as one of the sport’s rising featherweights.
By the end of 2013, he had won three UFC bouts in a row, including a split-decision win over Rony Jason in Brazil and a late-round stoppage of Estevan Payan at UFC 168 in Las Vegas. His record stood at 18-4 with one no contest, and he looked poised for a title run.
However, Peralta ran into tough stylistic matchups in the light Featherweight division. He suffered a unanimous decision loss to Akira Corassani in Stockholm, after which he tested positive for marijuana, resulting in a fine and a temporary setback.
Against Thiago Tavares in Bangor and veteran Clay Guida in Fairfax, he dropped consecutive decisions. A TKO loss to Sheymon Moraes at WSOF 26 in late 2015 led to his release from the UFC.
Undeterred, Peralta signed with World Series of Fighting and dropped a hard-fought bout to Moraes via second-round TKO. In 2017 he ventured to Abu Dhabi under the Brave CF banner and was submitted by Alan Omer in the third round. He reset his career later that year by headlining California Cage Wars 1, where he beat Shad Smith by unanimous decision.
A scheduled fight at King of the Cage: Under Siege in 2018 fell through, but Peralta rebounded by signing with Bellator. At Bellator 201, he faced Juan Archuleta and was knocked out in the third round, marking his final MMA contest.
Seeking a fresh challenge, Peralta transitioned to bare-knuckle boxing. He made his debut under World Bare Knuckle Fighting Federation in 2018 with a unanimous decision win over Jay Cucciniello. In December 2021 he joined BKFC, defeating Peter Petties by decision in Tampa, then edged Martin Brown by split decision in Jackson, Mississippi, in 2022.
On February 2, 2024, he faced rising prospect Bryce Henry and experienced his first bare-knuckle loss via second-round TKO. Already booked to fight JorDan Christensen in January 2025, Peralta continues to apply his MMA-honed striking in a new combat arena, proving adaptability and toughness late into his combat career.
