Singaporean-American MMA fighter nicknamed Unstoppable, the first ONE women's atomweight world champion, now retired from competition.
Lee grew up in a martial arts family and was introduced to martial arts at a very young age by her parents, both decorated martial artists. She became a two-time pankration world champion, won the Hawaii state wrestling tournament in 2013, and earned a black belt in Brazilian jiu-jitsu.
In May 2015, she made her professional MMA debut at ONE Championship. Later that year, she joined the Evolve Fight Team in Singapore and recorded five consecutive victories.
In May 2016, after a five-round fight against Mei Yamaguchi, she won the first ONE Women's Atomweight World Championship. In May 2017, despite suffering from pneumonia, she defended the title by submitting Istela Nunes with an anaconda choke.
After multiple title defenses, she moved up a weight class to compete for the ONE Strawweight World Championship. She trained at Evolve MMA and United MMA and has since retired from competition.
