​Meyram Maquine and Ruan Alvarenga are poised to ignite a gripping rivalry inside ONE Championship, as they clash in a high-stakes featherweight submission grappling bout at ONE Fight Night 46 on Prime Video. The event will air live in U.S. primetime on Friday, August 14, and take place at the storied Lumpinee Stadium in Bangkok, Thailand. The card is anchored by a blockbuster main event in which two-sport ONE World Champion Stella “Always Hungry” Hemetsberger defends her ONE Women’s Strawweight Muay Thai World Title against the dangerous challenger Natalia “Karelian Lynx” Diachkova. When Maquine and Alvarenga square off on the global stage, spectators can anticipate an elite technical duel underscored by genuine personal pride.
Maquine’s arrival in ONE Championship represents one of the most eagerly anticipated additions to the promotion’s submission grappling division in recent memory. Born in Manaus, Brazil—a region renowned for producing top-tier grapplers—Maquine trained in capoeira and Brazilian Jiu-Jitsu from the age of five. Under the mentorship of the esteemed Luiz “Guigo” Guilherme in São Paulo, he rapidly ascended the ranks, ultimately becoming a two-time IBJJF World Champion, clinching gold in both 2022 and 2024. At the 2024 World Championships, Maquine dominated his weight class and earned a medal in the absolute division, an achievement that echoed Royler Gracie’s 27-year-old record as the lightest competitor ever to stand on the absolute podium at IBJJF Worlds. Maquine’s elite finishing instincts translate seamlessly to ONE’s rapid, submission-focused grappling format. He excels from top control and possesses a dangerous offensive repertoire off his back, boasting an impressive 135-win career with 68 submissions. The 25-year-old phenom already holds notable wins over established ONE stars, including Fabricio “Hokage” Andrey, Owen Jones, and, most prominently, current ONE Flyweight Submission Grappling World Champion Diogo “Baby Shark” Reis.
Maquine is clearly ready to make a bold statement, and his eagerness to avenge a previous defeat to his upcoming opponent adds an extra layer of intensity to this promotional debut, elevating it beyond a typical first encounter.
In the opposite corner, Ruan Alvarenga brings a measured, fundamentals-driven approach to his own monumental promotional debut. As the son of Iran Brasileiro Alvarenga, the renowned instructor who helped nurture pound-for-pound great Marcelo Garcia, Alvarenga was immersed in the sport from an early age. He continued his education under Garcia’s tutelage in New York City, honing his skills with one of the sport’s most respected mentors. This lineage and training background shape an opponent who prioritizes precise technique, disciplined structure, and a methodical path to victory.
The clash between Maquine and Alvarenga promises to be a technical masterclass, with both fighters bringing distinct philosophies and deep competitive pedigrees to the table. Maquine’s explosive finishing capability and prior success against established ONE competitors will test Alvarenga’s fundamentals-first game, while Alvarenga’s lineage of elite instruction and meticulous training will challenge Maquine to navigate a fight plan tailored to control, positioning, and subtle pressure.
With the bout serving as a marquee showcase for ONE Fight Night 46, fans can expect a high-level exchange that blends grappling artistry with personal rivalry, set against the backdrop of Lumpinee Stadium’s revered atmosphere. As the world watches, Maquine and Alvarenga will not only seek victory but also cement their places in ONE’s storied grappling division, delivering a clash that could reverberate across the sport for years to come.
