Helena Crevar, an American submission grappler who is 18 years old, has officially signed with ONE Championship in a major move that is likely to transform the career of this young athlete. It will be announced on December 11, 2025 and will make Crevar one of the most promising talents of the promotion, combining her explosive style with the global platform of ONE that includes MMA, Muay Thai, and elite grappling bouts.
Crevar: Meteoric Rise of Prodigy to Black Belt
The rise of Crevar to stardom started at an early age. She moved to Texas at a tender age of 15 years to train under the famous coach John Danaher, where she was exposed to a rigorous environment that made her skills perfect. At the age of 17, she made history as the youngest woman to ever podium at the highly regarded ADDC event, and gained extensive media notice as a so-called generational talent.
Her resume has titles of championships with major organisations such as IBJJF, Polaris, and CJI, and it is a testimony to her success in no-gi tournaments. Her aggressive style, which consists of constant attacks, positional control, and submission hunting, has given Crevar a fan following with a similarity to established stars in the sport.
Why ONE Championship? The Vision of the Future of Crevar
What drew Crevar to ONE? She is a long-term fan of the promotion who has been motivated to watch players such as Garry Tonon and Giancarlo Bodoni perform on its stage. The varied and fight proposals, huge audiences, and beautiful location closed her deal. As she herself puts it, the opportunity was electric, which encouraged her to go even further when it comes to pushing boundaries.
She works best when pressured, and she does not consider high expectations as a burden but as an energy source to perform well. The rule set, which is one 10-minute submission-only round, fits perfectly in her philosophy as both warriors have no opportunity to use points or penalties.
Premier on the Horizon: Clash at Lumpinee Stadium
Crevar is not long waiting to make her mark. She is set to make her promotional debut at ONE Fight Night 39 on January 23, 2026, in Bangkok at the Lumpinee Stadium, which is an iconic venue in this city.
She will be fighting against Teshya Noelani Alo in a bantamweight grappling match, and it is going to be a fierce battle. This event marks the beginning of the U.S. primetime schedule of ONE in the year, which will increase the exposure of Crevar to a global audience. Her trademark forward pressure will be welcome by the fans, and she will be hoping to set the rhythm and get a finish.
Creating a Heritage: Headlines and Fight Clubs to Come
Crevar is ambitious, looking beyond her debut. She will be fighting frequently with the goal of winning titles in the 145 or 155-pound division to establish her reputation. This signing will not only boost her career but also create a huge sense of promise by ONE that they are willing to invest in young grapplers.
With the evolution of MMA, the participation of Crevar may make a new generation of athletes eager to follow the old forms of jiu-jitsu combined with the entertainment. The future is bright with this teen sensation in the highly competitive world of combat sports with her skills, personality, and spirit.
