Brazilian Jiu-Jitsu Superstar Helena Crevar Signs With ONE Championship

ONE Championship has officially signed 18-year-old phenom Helena Crevar to compete in the promotion’s submission grappling division, adding yet another promising young star to its world-class talent roster.

The Las Vegas native established herself as a generational talent when she became the youngest ADCC World Championship podium placer at just 17 years of age, capturing silver in 2024.

A product of the renowned New Wave Team under legendary coach John Danaher, Crevar has been competing against Brazilian Jiu-Jitsu’s biggest stars and has consistently proven she belongs among the sport’s best.

After moving to Austin, Texas, at just 15 years old to train under Danaher, she quickly became recognized as a major prospect in both gi and no-gi competition.

Crevar’s black belt promotion ceremony in June 2025 marked 10 years since she first stepped onto the mats, highlighting her dedication to the sport from an early age.

Crevar’s impressive resume includes capturing the Polaris 70-Kilogram Title in 2024 and claiming multiple IBJJF World and Pan Championships across different belt levels.

The American star’s rapid ascent through the ranks has been nothing short of remarkable, and now she’s ready to mix it up in the world’s largest martial arts organization.

With her combination of technical excellence, finishing ability, and championship pedigree, Crevar represents the future of women’s submission grappling.

Crevar’s debut has not yet been confirmed, so stay tuned to onefc.com for more news about her first promotional appearance.
