ONE Championship's upper echelon has been graced by several big names, but in the women's mixed martial arts (MMA) scene, none stand taller than Angela Lee and Xiong Jing Nan.

The Singapore-based combat sports outfit revealed that the pair's trilogy fight will take place at ONE on Prime Video 2 on September 30 as they find closure to their rivalry.

Lee, the reigning women's atomweight queen, has yet to be beaten in her division since her maiden debut and went on to win the title against Mei Yamaguchi in May 2016.

She has rarely looked back ever since, successfully defending her title five times.

The same can be said for Xiong after defeating Tiffany Teo for the inaugural women's strawweight title in January 2018 and she has racked up six title defenses to date.

Xiong and Lee's first meeting in March 2019 had immense historical purposes since both women were undefeated in their ONE Championship careers then–the former riding a four-fight win streak and the latter risking her own nine-fight streak to become the first female double champion in the promotion.

Things did not end well for Lee in her move up to the strawweight division as she was finished off by "The Panda" in the fifth and final round that started with a side kick to the body.

After Lee's failed foray, it was Xiong's turn to take a shot at making double champ status when she moved down to the atomweight division and challenged the Singaporean-American for her title in October of that year.

Similar to their initial fight, both fighters were not willing to move an inch as the opportunity to etch their names in history was simply too great to pass up.

However, Lee exacted her revenge on Xiong this time around when she locked in a rear-naked choke with about 20 seconds left on the clock.

With each woman having a win over the other, a rubber match for Xiong's strawweight title is the perfect way to end it.

It is certainly going to be a full circle moment for both women after cleaning out their respective divisions and fighting over the title that was on the line in their first matchup.

Xiong and Lee's storied rivalry will come to a close inside the ONE Championship cage on September 30 in the main event of ONE on Prime Video 2.
