Nick 'Nicky Rod' Rodriguez earned the nickname 'Black Belt Slayer' when, as a blue belt with barely a year of training, he reached the finals of the 2019 ADCC World Championship by defeating three seasoned black belts. A two-time ADCC silver medalist (2019, 2022), he co-founded B-Team Jiu-Jitsu and earned his black belt in December 2023 after just over five years of training, one of the fastest progressions in elite grappling history.
