Pereira’s path is one of the strangest in modern MMA. He grew up in São Paulo and was working at a tire shop with an eighth-grade education when, at 22, he first walked into a kickboxing gym, according to a 2025 Washington Post profile. He built a full kickboxing career first, winning two-division world titles in Glory before signing with the UFC in 2021. His MMA pro debut predates that move, but it was the UFC arrival, backed by the team around Cruz and the late Glover Teixeira, that turned him into a global name. No wrestling pedigree. No jiu-jitsu black belt to fall back on. Just a left hook and a calf kick.
He is a kickboxer first. He lands 5.16 significant strikes per minute at 67 percent accuracy, numbers that read more like a featherweight volume puncher than a 205-pound finisher. The signature weapon is the left hook off the jab, set up by a low kick that has folded opponents in half. His takedown defense has been tested at light heavyweight and held up enough to keep fights standing. Length helps: he is 6-foot-4 with a long, stabbing jab. The known hole is cardio under sustained grappling pressure, exposed by Israel Adesanya in their 2023 rematch and by Magomed Ankalaev over five rounds in March 2025.
The résumé at 205 pounds is the core of his case. He won the vacant title by stopping Jiří Procházka at UFC 295 in November 2023, defended it against Jamahal Hill at UFC 300 with a first-round knockout, finished Procházka again at UFC 303, then iced Khalil Rountree Jr. in the fourth round at UFC 307. Ankalaev took the belt by unanimous decision at UFC 313, the first real dent in the run. Pereira answered at UFC 320 in October 2025, stopping Ankalaev by TKO in 80 seconds to take the championship back. Seven of his nine UFC wins have come by knockout, per BBC Sport.
He now sits as the reigning light heavyweight champion with a clear pull toward heavyweight. Bleacher Report reported in May 2026 that Pereira vacated the title to face Ciryl Gane for an interim heavyweight belt at the UFC’s Freedom 250 card on June 14, with a three-division title on the line. Whether that fight stamps him as the best UFC champion of his era or exposes the limits of a kickboxer in deep water is the question his career now turns on.
