Marcelo Mello is a former UFC fighter and a Brazilian jiu jitsu black belt, officially under Royler Gracie, who also trained extensively with the late Master Carlson Gracie. A historical figure in the sport having helped establish the Brazilian grappling style in places such as Argentina and the USA, Mello's path in jiu jitsu is also unique one, as he was awarded his black belt on two separate occasions (in 1994 and in 1997) by two separate instructors, Carlson and Royler Gracie respectively.
