Mixed martial arts career

His professional MMA debut took place in 2012, but his early career had a rocky start. Over his first nine fights, he faced several challenges, finishing with a 5-4 record. These setbacks were partly attributed to his competing in an unsuitable weight class and a lack of discipline in his training regimen. Eventually, Prates honed his skills and found his stride, particularly after an extended stay in Thailand, where he gained valuable experience in Muay Thai.
Prates fought extensively in the Asian MMA scene, participating in events like China’s Chin Woo Men and Thailand’s Full Metal Dojo.
He also joined ONE Championship’s Warrior Series in 2019, where he gained recognition with wins against fighters such as Gunther Kalunda. Prates compiled a record of 15-6 from 2012 to 2023 before being invited to Dana White's Contender Series.
