Fighters

Yutaka Saito

The inaugural RIZIN featherweight champion and a former Shooto world champion, a cerebral veteran out of Paraestra Koiwa. He held the RIZIN belt from 2020 to 2021; his most recent outing was a 2024 KO loss to Yuta Kubo.

Ren Hiramoto

A charismatic striker who crossed over from kickboxing and became one of RIZIN's biggest draws. He shocked Mikuru Asakura with a first-round TKO at Super RIZIN.3 in July 2024; a planned 2025 rematch was cancelled when he withdrew with a shoulder injury.

Charles Oliveira

The most prolific finisher in UFC history, holding the records for most submissions and most finishes. A former lightweight champion, he lost a vacant-title bid to Ilia Topuria at UFC 317 (June 2025) but bounced back to win the 'BMF' title over Max Holloway at UFC 326 in March 2026.

Magomed Ankalaev

A long, technical Dagestani southpaw who took the light heavyweight title from Alex Pereira at UFC 313 (March 2025). Pereira reclaimed it with a first-round TKO at UFC 320 (October 2025); Ankalaev remains the top contender, with a bout against Khalil Rountree Jr. set for July 2026.
