Micael 'Mica' Galvao became the youngest male BJJ black belt in history at age 17 and in 2024 completed the 'Super Grand Slam' -- winning all four IBJJF majors plus the ADCC World Championship in a single year, only the second person ever to achieve this after Cobrinha in 2007. Trained by his father Melqui Galvao in Manaus, he dropped out of school at 13 to train full-time and has become one of the most dominant grapplers of his generation across both gi and no-gi.
