Zappary evolves into Frazzel starting at level 29.
A fair-skinned humanoid Yo-kai with short blonde hair tied in a bun, sky blue eyes, and bangs that cover the right eye. He wears a pair of dark gray hakama with the regular gray bottoms appearing ripped, and a white rope tied as a belt, matching the material on each wrist. An electric pouch can be seen draped on his side. He carries a bronze colored spear.
