Gabriel de Souza Bonfim (born August 20, 1997) is a Brazilian mixed martial artist and former professional boxer who competes in the welterweight division of the Ultimate Fighting Championship. Known by the nickname Marretinha, he is widely recognized for his grappling-heavy finishing style, with the majority of his wins coming by submission. He is a former Legacy Fighting Alliance Welterweight Champion and is currently ranked among the top welterweight contenders in the UFC.
Training out of Brasília, Brazil, with his family-led team, Bonfim Brothers Academy, he has built a reputation as a dangerous finisher inside the Octagon. He is the brother of fellow UFC fighter Ismael Bonfim, and the two are often mentioned together as one of the most notable sibling pairings in modern mixed martial arts.
Early Life and Background
Gabriel de Souza Bonfim was born on August 20, 1997, in Brasília, Brazil. He was raised in a large family of eleven children, where resources were limited and responsibilities were shared among the siblings from a young age. During his childhood, his father struggled with alcoholism and eventually abandoned the family. In response, his older brother and sister stepped in to find work and help provide financial stability for the household.
Growing up in Brasília, Bonfim was exposed to combat sports at an early age, influenced heavily by his older brother Ismael Bonfim, who also pursued a career in professional mixed martial arts. The two brothers later founded Bonfim Brothers Academy, a gym that would become the foundation of Gabriel’s professional fighting career and serve as his training base throughout his rise through the sport.
Path to MMA
Bonfim began his professional fighting career in 2014, initially competing in the bantamweight division. He quickly transitioned between weight classes, moving from bantamweight to lightweight in 2016 and later to welterweight the same year, where he has remained active ever since. During his early years, he also built a professional boxing record of 5-0 with one knockout, showcasing his striking abilities alongside his developing mixed martial arts skillset.
From 2014 to 2019, Bonfim competed extensively in regional Brazilian promotions, amassing an undefeated mixed martial arts record of 10-0. His performances in these regional circuits, combined with his parallel success in professional boxing, helped establish him as one of the promising prospects in Brazilian combat sports. This strong developmental foundation paved the way for his move to the American-based Legacy Fighting Alliance.
