He is more jolly and playful than he is in the game, and behaves in a more sassy and childish manner. The Devil is manipulative, evil, flamboyant, and has an obsession with collecting souls. At the end of the same episode, he wears a train conductor costume when he plays with his toy train. As shown in " A Very Devil Christmas", his winterwear consists only of a striped red scarf. In " Roadkill", when mistaken as a stray cat by Elder Kettle, he's briefly seen wearing a pink bow on his head. In " Release the Demons!", he briefly appears having apparently just gotten out of the shower, draped in two pink towels, one around his body (and held up to his chest) and one around his head (or, more accurately, his horns).

In " Sweater Off Dead", he's briefly seen wearing a party hat.

Clothed or not, he goes barefoot throughout the episodes, except for his outfits during his performance in the Underworld and later his audition in " Cupstaged" where he wears a blue and purple prince-like theater costume and pink ensemble with a black top hat and high-heeled boots respectively. His primary outfit consists of a white tailcoat with a matching top hat, white spats, and a red bow tie, that he wears during his song in " Carn-Evil" and during the dance battle against Ms. While the Devil is essentially naked, not counting his fur, he is briefly seen wearing various outfits and accessories in the show, most notably during the third season. Two more notable differences from his in-game counterpart are that he shows a bit of fat and his ears are a bit longer and spikier.

His fur is softer and less scruffy and has also gained a slight blue tint. In addition to now always shown as having a tail, his nose has gained a red flush along with having longer yellow horns instead of white horns, and the red irises he is only occasionally depicted with in-game are now a permanent part of his design. The Devil's design for The Cuphead Show! remains more or less the same, with only a few stylistic changes made.
