Black belt at 17. The IBJJF Grand Slam and ADCC gold in the same year at 20 — only the second person ever to do both. And 85 of his 111 recorded wins by submission.
Melbourne — Micael "Mica" Galvão was born in Manaus on 8 October 2003 and entered his first jiu-jitsu competition at four. In 2019 he was juvenile champion at the IBJJF Worlds, Pans and European Open and at the Brazilian Nationals. He took up Luta Livre at ten and holds a black belt in it too.
He was promoted to black belt in jiu-jitsu on 9 July 2021, at 17. Four months later, at 18, he won the 77kg division at the Abu Dhabi World Pro, the youngest black belt ever to win it. In 2022 he reached the ADCC 77kg final and lost it to Kade Ruotolo.
2024 was the year the record changed. He won the IBJJF European, Pan American and Brazilian championships at middleweight and the World Championship at lightweight — the IBJJF Grand Slam. In August he won ADCC gold at 77kg, finishing Vagner Rocha with a rear naked choke in the final. The Grand Slam and ADCC gold in one year has a name, the Super Grand Slam, and one other person has done it: Rubens "Cobrinha" Charles, in 2017, at 37. Galvão was 20.
The figures below are what that career looks like when it is counted.
Each point is a dated result, placed at his age on the day.
Each corner is a black-belt title he has won, with the year. A full hexagon is not a rating: it means every one of the six has been won.
Wins by method, as recorded by BJJ Heroes.
His 85 recorded submission wins by technique. Rear naked chokes, chokes from the back and bow-and-arrow chokes together account for 36 (42%). The armbar, with 17, is the single most common finish.

Leg locks are a small part of his game: five of 85 submissions (two inside heel hooks, two straight ankle locks, one kneebar). They are also how he has been submitted. Both of his two recorded submission losses were leg locks, one inside heel hook and one straight ankle lock. At ADCC 2024 he lost twice in the absolute division, to Elder Cruz and Dante Leon, both by submission, on the same weekend he won 77kg.
His 2022 IBJJF world title was withdrawn after a positive test for clomiphene, and he accepted a one-year suspension from 22 July 2022. He did not compete at the ADCC World Championship in Kraków in September 2026, where he would have defended his 77kg title.
Birth, belts, juvenile titles, the 2022 and 2024 ADCC results and the 2022 suspension are from his Wikipedia entry, checked against primary reports. The 2024 Grand Slam events are from IBJJF's athlete results. The Abu Dhabi World Pro record is from Bloody Elbow (20 November 2021); the 2022 final from FloGrappling; the Super Grand Slam and the 2024 final from FloGrappling.
The win, loss and submission counts are from BJJ Heroes, a fan-compiled database, as read on 29 October 2026; they are not an official record and cover the matches BJJ Heroes has logged. BJJ Heroes lists 111 wins; its methods add to 110, and the figure shows the 110. Ages are calculated from his date of birth and the date of each result.
