Allycia Hellen Rodrigues profile

Allycia Hellen Rodrigues is the ONE women's atomweight Muay Thai world champion and has held the belt since August 2020, the longest reign of any woman in the promotion. She was born in Fortaleza, Brazil, and fights out of Phuket Fight Club in Thailand.

A world title in her first fight

On 28 August 2020 at ONE Championship: A New Breed she made her promotional debut against Stamp Fairtex, a two-sport ONE world champion, with the inaugural women's atomweight Muay Thai world title on the line. She took it by majority decision.

Her overall Muay Thai record stands at 36-6, most of it built on the Brazilian and Thai circuits before she signed. She is not a fast starter: she leans on knees and a long game, and collects the late rounds when her opponent slows.

Five defences

She unified the division against Janet Todd by unanimous decision on 25 March 2023, then beat Cristina Morales on points in March 2024.

In 2025 she began finishing fights: a fourth-round TKO of Marie McManamon in March and a third-round knockout of Johanna Persson in July, both worth performance bonuses.

Five rounds with Phetjeeja

Her fifth defence, on 19 June 2026 at ONE Friday Fights 159 in Bangkok, was against Phetjeeja Lukjaoporongtom, the reigning ONE women's atomweight kickboxing champion moving across to Muay Thai.

It went the full five rounds and she kept the belt on a split decision. The rematch talk started the same night.

The one loss, and a son

Her only defeat in ONE came when she moved up a division: Smilla Sundell stopped her in the third round of a strawweight title challenge on 29 September 2023. She returned to atomweight and won four straight.

Her son was born on 27 September 2021, in the middle of her reign, and she has said she now fights for herself and for him.
