Gato/Story

Garou: Mark of the Wolves
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.

Gato also appears in Hotaru's ending. In her ending, she finds Gato and claims that he's her older brother, to which he harshly denies even knowing her, which caused her to slap him. He then leaves her there, and Hotaru silently prays for her older brother to come back to her.

The King of Fighters series
''Gato's life in this timeline seems to mostly be based of his Fatal Fury counterpart up until Garou: Mark of the Wolves. However, it is implied the events of Garou MOW did not occur yet in this timeline.''

The King of Fighters 2003
Geese Howard summon and coerce him to form a team with Geese's other agents for the tournament, Billy Kane and Ryuji Yamazaki. Gato does so to prevent Hotaru from being harmed. He loathes his teammates and immediately ditches them in their ending.

The King of Fighters XI
He enters the KOF XI tournament because B. Jenet said that she had information regarding the whereabouts of his father. During the "Mark of the Wolves Team" ending, Gato swiftly leaves B. Jenet, the Lillian Knights and Tizoc at the Pao Pao Cafe, to avoid being seen by his sister, who was looking for him.

The King of Fighters XV
Growing impatient and seeking to hunt his father down, he reluctantly agrees to an offer with B. Jenet to join their team in exchange of information about his father, sternly warning the pirate to uphold her end of the deal. Eventually all goes well and Gato got the information he wanted, and promptly leaves.

Hotaru tries to call out her brother, but he roughly brushes her off, warning her to stay away for her own safety, telling that the town she's in will be dangerous for her; this implies that Gato has already read some information from the USB device that Jenet offered to him and has already some idea on the whereabouts of his father, whom he seeks to defeat.
