Nascimento’s martial arts journey is deeply intertwined with the modern resurgence of Brazilian MMA excellence. Sharing the mats daily with former UFC lightweight champion Charles "Do Bronx" Oliveira, Nascimento has sharpened a submission-first arsenal that translates seamlessly to the Octagon. His moniker "Puro Osso" (Pure Bone) reflects his lean, rangy frame—a physical build that grants him significant leverage advantages during complex grappling exchanges.

Before securing his spot on the global stage, Nascimento built his reputation across highly competitive regional promotions, including Legacy Fighting Alliance (LFA). Though his initial appearance on Dana White's Contender Series (DWCS) in 2018 ended in a razor-thin split decision loss, his relentless work ethic and technical evolution eventually forced the UFC's hand. His subsequent promotional debut and subsequent victories proved he belonged among the division's elite.
