Satan

Satan is a major character in Helluva Boss who made his official debut in the episode "Mastermind". He is one of the Seven Deadly Sins, embodying the sin of Wrath. Due to Lucifer Morningstar's absence, Satan became the acting leader of the Sins and ruler of affairs in Hell, though he claims to be the true ruler. Satan is a titanic and muscular draconic demon. His skin appears to be different shades of red with claw-like fingers, darker-red markings, and warm orange-yellow lava-like stripes covering his wings, neck, and left arm, while on his right the stripes are dark red. He also sports black spikes coming out his back, all the way down to his large, demonic tail, which has a spearhead-shaped point at the end. Satan is dressed in a way that is reminiscent of traditional American western-style clothing, as a nod of his association with imps of the Wrath Ring. Matching the sin he represents, Satan is shown to be a very wrathful demon with anger issues and he chronically has outbursts which leave him out of control. His uncontrollable rage is too much to the point that he needs a therapist to act like a "shoulder angel" to remind him to keep calm. Despite this, he can also be reasoned with and well-sophisticated most of the time, unless he is provoked. Despite this, however, Satan is implied to have a slightly friendlier demeanor when off-the-clock, which is suggested with Beezlebub's comments and how she saw him as a brother figure.
