Early Life and Background
Brendan Cody Allen was born to Michelle Allen and James Allen and raised in Louisiana. His maternal grandparents hail from Edmonton, Alberta, Canada, a family tie that would eventually shape parts of his career. Allen has an older brother, and it was alongside him that Brendan first walked into a Brazilian Jiu-Jitsu class at the age of 13, an experience that sparked his lifelong passion for combat sports.
During his high school years, Allen began competing in Mississippi after gaining early exposure to wrestling and boxing. He later attended Southeastern Louisiana University, where he studied criminal justice while continuing to sharpen his martial arts skills. These formative experiences laid the foundation for his transition into professional mixed martial arts.
Path to MMA
After completing his education, Allen joined Clementi’s Gladiator Academy to train in mixed martial arts and begin his professional journey in 2015. That same year, he captured the IMMAF Amateur Middleweight Championship, signaling his readiness for the professional ranks. Allen turned professional shortly after, beginning his career fighting in various promotions across the southern United States.
His early professional path included stints at multiple regional shows before he earned a shot at the Legacy Fighting Alliance (LFA) middleweight title. Allen became a two-time LFA Middleweight Champion, defeating Tim Hiley at LFA 50 and later Moses Murrietta at LFA 61. These victories positioned him as one of the most promising middleweight prospects outside the UFC.

A setback came in November 2020 when he lost to Sean Strickland via technical knockout in a catchweight bout.
In 2021, Allen rebounded with a submission win over Karl Roberson at UFC 261 and a unanimous decision victory against Punahele Soriano. His momentum was briefly halted by a second-round TKO loss to Chris Curtis at the end of the year, but he remained firmly on the UFC roster.
