Martial Artist, Gai hails from Japan
and he calls his fighting style "total combat." He is a balanced stand
up fighter skilled with punch and kick combos, and is also a decent grappler.
When Gai heard the news of the upcoming Buriki One tournament, he
decided to enter to test his skills. During the tournament, he started a
rivalry with American boxer Rob
Python. His first appearance
in the King of Fighters tournament was in KOF '99 as an extra striker. He
later appeared in KOF 2000 as
extra striker. In King of Fighters XI, he finally entered the tournament
himself to test his skills. He is loosely based on manga character Baki Hanma
from Baki the Grappler.
