Japolo

A small, ferret-like creature, Japolo appears in episodes 1-4. He is Tiara's "partner", according to Guardian World terminology. Despite this name, Tiara and Japolo are neither peers nor equals. Japolo serves Tiara as a familiar and acts as a battery-pack and backup to her powers. He is highly intelligent, and possesses much knowledge which Tiara doesn't about her mission and why the Throne was stolen. Japolo's powers include being able to freeze time by creating suspension fields (which allows battles to go in crowded cities without anyone noticing), and detecting other magical presences from his world.
