Why ONE X is ONE Championship's biggest event ever and why you must tune in!

Combat sports fans around the world are looking forward to ONE X. The event features action from MMA, Muay Thai, kickboxing, and submission grappling. It is the 10-year celebration of ONE Championship and you must tune in.

The extravaganza features several big names and multiple titleholders: current champions, Grand Prix champions, a UFC champion, Muay Thai champions, kickboxing champions, GLORY kickboxing champions, K-1 champions, Brazilian jiu-jitsu champions, and more.

Demetrious Johnson is a former UFC champion and an MMA all-time great. He was knocked out last year by Adriano Moraes, who will face another knockout king Yuya Wakamatsu at ONE X.

Johnson himself will meet Muay Thai champion Rodtang Jitmuangnon on the Grand Finale card. Rodtang is the reigning ONE flyweight Muay Thai champion with over 250 wins. The two will face off in a special-rules bout.

The main event of ONE X is a women's atomweight showdown. Stamp Fairtex is looking to become a triple-sport champion, having already held titles in kickboxing and Muay Thai.

Stamp became the division's top contender last year when she won the Atomweight Grand Prix. In the final, she used an armbar submission to defeat the Commonwealth Games gold medal-winning wrestler Ritu Phogat.

Standing in her way at ONE X is Angela Lee. The Singaporean-American is looking to add one more title defense to her name on March 26. This is her first event back since having a child.

Then there is South Korean Seo Hee Ham, who has been a champion in RIZIN, DEEP Jewels, and more. She will face rising Filipino star Denice Zamboanga in a rematch after winning their first fight in a controversial decision.

Japanese MMA legends will also feature, with Yoshihiro 'Sexyama' Akiyama in a grudge match against Shinya Aoki. The two have fought everywhere, from the UFC, PRIDE FC and DREAM to Bellator, Strikeforce and K-1.

Furthermore, the ONE middleweight and light heavyweight champion Reinier de Ridder will welcome Brazil's André Galvao to the ONE circle. Galvao is one of the greatest Brazilian jiu-jitsu competitors in history, with over 20 world championships to his name. The two will face off in a submission grappling match.

ONE X will be in three parts on March 26 and is a must-watch for any combat sports fan.

ONE X will also feature the Featherweight Grand Prix final. The kickboxing competitors at this event have won titles in GLORY, K-1, Enfusion, and more.

K-1 kickboxing champion Chingiz Allazov will look to win a ONE world title against Sitthichai Sitsongpeenong. The Thai fighter has over 120 career victories and has held titles in GLORY, Lumpinee, and more. The two blistered the competition in 2021 and are now meeting in the finals of the Featherweight Grand Prix.

Superbon Banchamek, the ONE featherweight kickboxing champion, is riding high after his stunning headkick knockout over all-time great Giorgio Petrosyan. On March 26, he will be looking to avenge a 30-second KO loss to Marat Grigorian, who is an aggressive striker with 34 wins by way of KO/TKO. Grigorian has held titles in GLORY and K-1 and is now looking to add a ONE title to his resume.
