Columbus is a pale yellow Cat Yo-kai having tidal blue ears, eyes with stars as pupils and smoke gray hair. He wears a navy blue captain's hat, a blue and navy blue suit, and is seen riding on a ship with an imprinted red cloud on the sail.
On Columbus' hat, you can see there's an egg with a wispy tip, lime green spots and a ring surrounding it, and a star shaped badge, which is most commonly seen on Great Legendary Yo-kai.
