Ban dwells as a solitary hermit on the remote planet Tears, coexisting with enigmatic alien creatures in self-imposed exile. A former collaborator and trusted ally of Dr. Saruta, he grants temporary sanctuary to Godo’s fugitive crew following their Earthbound escape, offering them respite to recover and plot their Phoenix pursuit. His assistance extends to securing vital resources and imparting veiled insights tied to their mission, while two native beings from Tears depart with the crew afterward, their relationship with Ban remaining largely undefined. Designed with the exaggerated, expressive traits characteristic of Tezuka’s archetypal figures, Ban serves both as a pragmatic facilitator—propelling the protagonists’ objectives through tactical aid—and an emblem of fragile cosmic alliances. His history, motives, and personal trajectory remain anchored solely to his role in the film’s events, unelaborated beyond this narrative framework.
