Snake  is a main antagonist from the Magic Kaito series. He is a codenamed agent in Magic Kaito's unnamed organization and the murderer of the first Kaitou Kid, Toichi Kuroba.
Snake revealed himself to be the one who killed Toichi Kuroba eight years before the events of Magic Kaito. It seems that Toichi's death may have been mistaken for an accident, since Kaito was shocked to learn from Konosuke Jii that his father was murdered.
Snake is searching for the Pandora Gem, which is said to grant immortality. He also intends to kill the Kaitou Kid once and for all, to stop him from getting in the way of his plans.
