Hopachai Apachai アパチャイ・ホパチャイ

A 28-year-old master of Muay Thai and is known as the "Death God" of the Muay Thai underworld fighting circuit.

Apachai has been fighting life or death battles in underground Muay Thai fights since he was a teenager. Later, he was an enforcer for a cruel pirate who accidentally fed Apachai while he was starving in a harbor in Thailand. He served this man faithfully until Hayato Fūrinji brought his misdeeds to Apachai's attention. The two of them then defeated the pirates, and Apachai has been at the dojo ever since.
