The atomweight Muay Thai division is about to witness a high-stakes collision of styles and ambition. Former ONE World Title challenger Johanna Persson is set to face the explosive Polish striker Martyna Dominczak at ONE Fight Night 43 on May 15, in a bout that promises fireworks from the opening bell.
This pivotal matchup, airing live on Prime Video from Bangkok's legendary Lumpinee Stadium, is more than just another fight on the card. For Persson, it's a critical opportunity to secure her first promotional victory and reassert her place among the division's elite. For Dominczak, it's a chance to derail a former title contender and build serious momentum.
Johanna Persson's story is one of rapid, relentless ascent. The Swedish fighter didn't begin her Muay Thai journey until age 23, but she has since compiled a formidable 13-4 record and captured a collection of major European titles. Her crowning achievement came in 2025 when she seized the WBC Muay Thai World Championship, a feat that earned her a direct shot at ONE gold in her promotional debut.
Though she fell to champion Allycia Hellen Rodrigues, Persson's resolve only hardened. After a canceled bout in March, she now returns with a singular focus: to prove her world-class status belongs on the global stage of ONE Championship.
Blocking her path is the dangerous Martyna Dominczak. The 24-year-old Polish phenom announced her arrival in devastating fashion, scoring a TKO victory over the respected Nat "Wondergirl" Jaroonsak. That explosive debut showcased the power and precision that makes Dominczak such a feared prospect. She represents the new wave of European strikers, hungry to topple established names.
This fight is a classic striker's duel with compelling narratives on both sides. Will Persson's championship-level experience and technical prowess be enough to handle Dominczak's ferocious power and momentum? Or will the Polish star score another statement win and crash the atomweight top tier?
For fans of elite striking, this is a must-watch clash. It's a battle between proven pedigree and dangerous ambition, where every kick, knee, and elbow could determine the next contender in one of martial arts' most thrilling divisions.
