Hebi-san is a fictional character from Galzoo Island, a character who appears as a snake-themed being. The name is presented as a single honorific-style title rather than a clearly separated personal and family name, so the most consistent matching form is "Hebi-san". In the series, Hebi-san functions as a minor supporting or encounter character associated with the island’s bizarre, comedic, and surreal atmosphere. The character’s role is mainly to add flavor, humor, and eccentric world-building to the setting.
