Sean Climaco

Rising flyweight Muay Thai star Sean Climaco is the latest United States-based striker to come to ONE Championship with dreams of making it big. 

“The One” was born and raised in California to parents who migrated from the combat sports hotbed of the Philippines, so fighting was in Climaco’s blood.

In fact, his father practiced martial arts and enrolled Climaco into the famed American Kickboxing Academy to study MMA after he and his younger brother had numerous quarrels.

Muay Thai, however, ultimately captured Climaco’s attention. While he continued training throughout his teenage years, it wasn’t until he graduated high school that the youngster decided to fully immerse himself into “the art of eight limbs.”

After making a name for himself on the local U.S. circuit, Climaco landed a spot in the Road to ONE: America tournament in 2023.

With his ultra-aggressive style proving too much for the competition, he blitzed the field to claim a coveted six-figure contract with ONE. Now, he plans to bring that same energy to the world’s largest martial arts organization.
