The Devil

As the series' own interpretation of Satan, the Devil is an appropriately sinister character, being feared for his adept use of trickery and deception. By taking advantage of his victims' latent greed, the Devil is shown to use gambling at his casino as a method by which to encourage his victims into making increasingly reckless, Faustian bets, eventually culminating in the forfeiture of their soul to him upon their loss. While only the ruler of the underground depths known as Inkwell Hell, the threat of his influence can nevertheless be felt all across Inkwell Isle. Even Cuphead and Mugman are said to have received "many warnings" by the Elder Kettle to steer clear of the casino entirely. He is also very evil, as when Cuphead loses and the devil wins the bet, he is always willing to take their souls with no problem at all. The Devil has no problem of using something to destroy a person during a battle, showing him as not just evil, but unusually very murderous too. Despite these traits, whenever he is talking to his closest minions, such as King Dice, he is usually happy and normal to talk and chat with him.

Both a liar and a cheat, the Devil naturally has no problem with going back on his promises so long as it benefits him, turning Cuphead and Mugman into his slaves for handing over the soul contracts in spite of promising to spare them if they do. He holds very little sympathy for those in his employment, as shown when he declares his right-hand man, King Dice, a "good-for-nothing lackey" after the latter has been beaten. Since then he had still remained as the dark figure that people fear, as all the other bosses were afraid about being the Devil's slaves.

In The Cuphead Show!, the Devil remains the same, but has a more flamboyant and comical side to him, acting sassy and a bit childish at times. In the first episode, he gleefully sings about how great it is to be him, how he adores being a naughty bully to the Isles' locals, and that collecting the inhabitants' souls is his favorite hobby.

The Devil's main trait is that he is incredibly prideful of himself, believing he'll always win and get what he wants in the end. This pride is what leads to his failures in both the game and the show. The Devil's design for The Cuphead Show! remains more or less the same, with only a few stylistic changes made. 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. His fur is softer and less scruffy and has also gained a slight blue tint. 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. He has a thick bubble booty 3 foot long dick and hefty balls he also loves his chubby loyal goofy henchman though he doesn't like to show it often but deep down he appreciates his henchman company.

The main subject is a muscular, black furred male demon with a large, defined chest and abs, sitting on a wooden bench with his arms raised above his head, stretching. He is waking up and sterching His broad chest and biceps, but is otherwise nude, revealing his large, erect penis. His facial expression is one of exaggerated surprise or discomfort, with his mouth open and eyes squeezed shut, and a small sweat drop near his forehead. This is a digital drawing in a cartoon style featuring an anthropomorphic orange cat with a muscular build standing with his back to the viewer. The devil has a thick tail that curves slightly upward and is wearing nothing to cover his broad shoulders and muscular back. His lower body is unclothed, revealing his well-defined, muscular buttocks and legs. The devil's fur is a black color with goat like ears and sharp tail tip.
