Lucas Protásio is the son of grappling veteran Clóvis Protásio and one of the main jiu-jitsu figures of his generation, holding the rank of black belt under Bruno and Thiago Barreto of Team Checkmat. Protásio made a name for himself in this sport during the early stages of his career as a blue and purple belt where he conquered the most important title available in those divisions, the World Championships with the International Brazilian Jiu-Jitsu Federation (IBJJF). Unable to compete during his brown belt year due to the restrictions set by the COVID-19 pandemic of 2020-2021, Lucas reappeared on the global stage as a black belt, immediately making his mark in the division with impressive debut performances at the Copa Podio Grand Prix and Abu-Dhabi Jiu-Jitsu Pro (AJP) league.
