The Devil is the demonic ruler of the Underworld, who continually torments the residents of Inkwell Isle and schemes to steal their souls. He is manipulative and evil with a flamboyant demeanor and an obsession with collecting souls. He's jollier and more playful than he is in the game and behaves in a more childish manner. However, he can be very intimidating when he needs to be. He is tall, covered in black fur, has long horns, red eyes, yellow sclera, and a red nose.
