Bio: Kato was Britt Reid's valet, who doubled as The Green Hornet's unnamed, masked driver and partner to help him in his vigilante adventures, disguised as the activities of a racketeer and his chauffeur/bodyguard/enforcer. According to the storyline, years before the events depicted in the series, Britt Reid had saved Kato's life while traveling in the Far East. Depending on the version of the story, this prompted Kato to become Reid's assistant or friend. In the anthology The Green Hornet Chronicles from Moonstone Books, author Richard Dean Starr's story "Nothing Gold Can Stay: An Origin Story of Kato" explores the character's background and how he ends up living in America, suggesting that Kato met Britt Reid on a later trip back to his homeland while in search of his mother.
