Gato

Gato is a character from Garou: Mark of the Wolves, who makes an appearance in The King of Fighters series. He is visually based on Retsu Kaioh from the Baki the Grappler manga series.

Fatal Fury
Gato is a martial artist who trained with his father constantly in his youth. However, when his father mysteriously killed his mother, he decided to abandon everything from his former life in order to get revenge. In his Mark of the Wolves ending, a stranger -believed to be his father- saves Kain R. Heinlein from the crumbling mansion. Gato is blinded by the stranger before he can act, and can do nothing while the stranger mocks him. He apparently loses his sight after the attack.

The King of Fighters
Gato first appears in The King of Fighters series in The King of Fighters 2003 as part of the Outlaw Team, along with Ryuji Yamazaki and Billy Kane. Gato is summoned to Geese Howard's office and forced to cooperate in order to prevent Hotaru from being harmed. Gato does not like his team mates at all, as revealed by the ending, in which Gato ditches the other two immediately and tells them off, leaving Yamazaki and Billy to fight. In KOF XI, he is partnered with Bonne Jenet and Tizoc to form the Garou Team. He joined them since B. Jenet said that she had information regarding the whereabouts of his father. He also immediately leaves them, though presumably on somewhat friendlier terms (he declines their invitation to celebrate).

Personality
Gato is ruthless and very serious; he grunts a lot. He cruelly looks down on others and rarely shows respect for them. Even so, he softens slightly before Hotaru's presence.
