The following year, his first as a black belt, Leo fought his way to the final against Marcio Feitosa in the first of many historical duels between the two. This first fight went to the Gracie Barra fighter, Feitosa, but in 1998 when the two met once again in the final, Leonardo was the victor in one of the hardest fights of the event. 1998 was the last time Leonardo won the World Championship, although he did make the final again in 1999 (losing to Royler Gracie) and placed 3rd in 2000.

His career’s highest point had not been reached however, that came in 2003 when Leonardo won the World’s most prestigious Submission Grappling title, the ADCC (Abu Dhabi Combat Club), a gold medal achieved again in 2005.

In between this period, Leozinho moved to Sao Paulo and was training under Fabio Gurgel at the Team Alliance HQ there until 2002 when a group of competitors joined up against the head coach Gurgel. Leonardo left the team together with most of the black belts that trained there. The argument (in broad strokes) was over the ‘Mundial‘ (World Championships by IBJJF federation) which occurred a week after the Copa do Mundo (World Cup). As the Copa do Mundo offered a good prize money to its competitors and the Mundial didn’t, Leonardo and his teammates felt they should support this organization (CBJJO – Confederação de Jiu Jitsu Olimpico) and compete in it, Gurgel however decided against it for reasons that were never made public. The fighters went on to fight at the ‘Copa’ and Gurgel banned them from the gym, and so Leozinho and the others formed another team, ‘Master Team’ to honor the gym where this group had started training in the 1980’s. The Master Team later became Brasa Clube de Jiu Jitsu.
