Jonathan “The General” Haggerty

Jonathan Haggerty is an incredibly accomplished martial artist, despite his relative youth.

He began training in Muay Thai at the age of 7 under the watchful eye of his father, who was himself an active competitor, and had his first bout just one year later. Since then, he has relentlessly pursued his dreams of becoming the best striker in the world.

He took one step closer to that goal when he joined ONE Championship in 2019, where he made a stellar debut by defeating future ONE Strawweight Muay Thai World Champion Joseph Lasiri.

One of the very best strikers to ever represent the United Kingdom, Haggerty then made waves around the planet in just his second bout in the world’s largest martial arts organization.

He defeated legendary Muay Thai World Champion Sam-A Gaiyanghadao in May 2019, capturing the ONE Flyweight Muay Thai World Title in the process to reach the pinnacle of his career.

After parting with his flyweight belt, the Orpington, England native then moved up a weight class and shocked the world in 2023 with a stunning first-round TKO victory over longtime ONE Bantamweight Muay Thai World Champion Nong-O Hama at ONE Fight Night 9.

Haggerty made history once again later in the year when he knocked out ONE Bantamweight MMA World Champion Fabricio “Wonder Boy” Andrade for the vacant bantamweight kickboxing crown at ONE Fight Night 16, becoming a rare two-sport ONE World Champion.
