ONE Championship’s women’s openweight submission grappling will crown its first-ever queen, as a teenage prodigy and a highly decorated veteran are ready to wage war for the throne.
Pound-for-pound great Helena “Jiu-Jitsu Girl” Crevar meets eight-time BJJ World Champion Kendall Reusing for the inaugural ONE Women’s Openweight Submission Grappling World Title at ONE Fight Night 51 on Prime Video. The 10-minute World Championship bout goes down live in U.S. primetime on Friday, January 8, from the iconic Lumpinee Stadium in Bangkok, Thailand.
A true generational talent, Crevar has rapidly become the face of women’s submission grappling and the sport’s ultimate gold standard at just 19 years old. Dominating on the world’s biggest stages since her colored belt days, the Kingsway Jiu-Jitsu product holds multiple IBJJF World and No-Gi World titles.

Relentless back control, an incredibly intricate guard, and a razor-sharp finishing instinct define her suffocating ground game. Under the meticulous guidance of John Danaher, she ascended from purple to black belt in less than a year, earning the distinct honor of becoming the legendary mastermind’s first female black belt.
That technical brilliance has translated seamlessly to the world’s largest martial arts organization. At ONE Fight Night 39 this past January, Crevar’s ruthless efficiency left Teshya Noelani Alo with absolutely no answers, forcing a lightning-fast tap via Estima Lock in just 100 seconds. Her sophomore appearance at The Inner Circle 22 in July showcased an entirely different weapon. Crevar clamped down on Paige Ivette Clymer with superior back control from start to finish, earning a one-sided unanimous decision that moved her to a flawless 2-0 in ONE.
Now, her shot at gold arrives on the heels of a historic, bracket-clearing run at the 2026 ADCC World Championship. Crevar cleanly submitted all three of her opponents in Krakow to claim the +65kg gold, cementing her status as the youngest ADCC Champion in history. That leaves the biggest prize in submission grappling — 26 pounds of ONE gold — as the lone accolade missing from her pristine resume.

Looking to abruptly crash that impending coronation is Reusing, a seasoned pioneer who has already planted her flag at the absolute summit. Long before Crevar was dominating international headlines, the Gracie Barra standout was actively paving the way for women in openweight competition. She captured the inaugural Polaris Women’s Openweight title in 2021 and successfully defended it as recently as this past March.
A black belt under her father, Tom, the 29-year-old is an eight-time BJJ World Champion. The ONE debutant’s wrestling roots run incredibly deep, boasting a California state title, four U.S. national titles, and a grueling stint on Team USA’s international circuit. That sturdy foundation fuels a punishing, heavy-pressure passing game, ensuring she carries genuine physical power into every single exchange.
Away from the competition mats, Reusing is a highly respected grappling commentator and podcast host who dissects the game just as effectively as she plays it. That analytical mind will meet Crevar’s own elite fight IQ in a fascinating tactical chess match.

The stylistic contrast is simply irresistible. Youth meets experience, and both elite athletes have already fundamentally reshaped what is possible in women’s grappling.
On January 8, only one grappler will rise as ONE’s first openweight queen, with historic gold gleaming at her waist.
