Lucas Souza

Lucas Souza was born on November 11, 1995, in Brazil, and from an early age demonstrated the competitive fire that would come to define his athletic career. Throughout the jiu-jitsu community, he is known by the nickname "Foguinho" — a Portuguese term meaning Small Fire or Little Fiery One — a moniker rooted in his early childhood that has followed him across every stage of his sporting life.

Before discovering jiu-jitsu, Souza channeled his athleticism into football (soccer), competing for the renowned Grêmio Foot-Ball Porto Alegrense club. The discipline and competitive mindset forged on the soccer pitch laid a foundation that would prove invaluable when he eventually transitioned to the mats. At the age of 18, in 2013, Souza took his first steps in Brazilian Jiu-Jitsu under coach Thiago Minu, whose technical guidance provided the grounding he needed. That foundation set the stage for the move that would shape the trajectory of his competitive career — a transition to Guetho Jiu-Jitsu under the instruction of Guto Campos.

Under Guto Campos at Guetho Jiu-Jitsu, Souza's progression through the belt ranks was defined by a steady accumulation of titles and a growing reputation on the IBJJF and CBJJ circuits. What set his colored belt career apart was not merely the volume of medals, but the caliber of events in which he delivered — continental championships, Pan-American tournaments, and national championships across multiple belt levels.

A defining aspect of Souza's journey was his commitment to completing his academic studies alongside his competitive career, balancing the demands of higher education with the rigors of elite competition. On June 7, 2022, upon concluding his academic career, Guto Campos awarded Souza his black belt — a milestone that closed one chapter and opened the next. Competing in the middleweight division at 82.30 kg / 181.5 lbs, Souza represents the Ghetto / Atos coalition, carrying the competitive momentum built across his colored belt years directly into his debut seasons as a black belt in 2022 and 2023.

Blue and Purple Belt: Building a Championship Foundation

Souza's trajectory through the belt system reads as a consistent upward march across jiu-jitsu's most competitive international stages. His elite potential first announced itself in 2017, when he claimed gold at the IBJJF Pan Championship at blue belt — a result that signaled a competitor ready to challenge at the sport's highest levels.

At purple belt, Souza continued building his résumé with authority. In 2018, he captured the IBJJF American Nationals title, and bronze-medal finishes at the 2018 IBJJF Pan Jiu-Jitsu Championship and the 2018 IBJJF American Nationals further illustrated his podium consistency during that period. In 2020, he added both the IBJJF South American Championship and the CBJJ Sul Brasileiro to his collection, demonstrating the versatility to perform across different competitive environments and geographies.

Brown Belt and Black Belt: Cementing Elite Status

The brown belt years proved to be Souza's most prolific stretch of competition. In 2021, he claimed the CBJJ Brazilian Nationals title — one of the most prestigious domestic championships in the sport — before capping his pre-black belt career with gold at the IBJJF European Open in 2022, an international result that underscored his readiness for the sport's highest division.

His transition to black belt competition required no adjustment period. In 2023, Souza won the IBJJF Sul Brasileiro at black belt, confirming that the competitive edge built across his colored belt years had carried seamlessly into the sport's most demanding arena. The breadth of his accomplishments — spanning blue, purple, brown, and black belt across both IBJJF and CBJJ competition — establishes Souza as one of the more complete competitive profiles to emerge from the middleweight division in the early 2020s.
