Yatan Bueno is a jiu-jitsu black belt under Fernando "Boi" Marques and Ubiratam dos Santos (Jacaré), who also represented the Dream Art Project in the sport's international circuit and later Team Fratres. Bueno's reputation as one of the top ultra-heavyweight athletes of his generation was earned during his colored belt career, particularly after his wins over Victor Hugo as a purple belt at the CBJJE World Championships and AJP Goiania Pro.
