They call him THE IMMORTAL — and after years of destruction inside ONE Championship, Regian Eersel has more than earned that name.

From the moment the Surinamese striking machine arrived on the global stage, Eersel brought a terrifying combination of pressure, precision, devastating knees and relentless combinations. Calm on the outside, absolutely ruthless when the bell rings, he built his reputation by walking through elite opposition and turning championship fights into showcases of controlled brutality.

Eersel didn’t come to ONE simply to compete — he came to rule.

Through brutal battles, championship wars and explosive finishes, The Immortal climbed to the top of both Kickboxing and Muay Thai, becoming a two-sport ONE World Champion and one of the most dominant strikers of his generation.

What makes Eersel so dangerous isn’t only his power. It’s the pressure that never stops. The long combinations. The knees through the middle. The ability to stay composed while the man standing across from him slowly realizes there is nowhere left to escape.

Now, as another World Title battle approaches, we look back at the fights that helped create one of the most feared champions in ONE Championship history.

This isn’t just a collection of fights.

This is the rise and reign of REGIAN “THE IMMORTAL” EERSEL.
