Lucifer Morningstar

appearance (normal): Lucifer is a slender-figured fallen angel who sports a close resemblance to his daughter, Charlie - having her milk-white skin with rosy-cheeks, blonde hair with thin light coral streaks on the thicker, paler blonde highlights, and eyes with light yellow sclera and red pupils. He is shorter than his daughter,[9] though not by a large amount.[10]

Unlike Charlie, his mouth is full of sharp teeth, his hair is cut short and has been slicked back with one tuft sticking out, his pupils are slit like a snake, and his cheeks are a paler shade of red. In addition, he also sports black sharp eyebrows, and his eyelids are light purple. His forearms also appear to be dark grey when his sleeves are rolled up.

Lucifer's white and red clothing is somewhat like that of a circus ringmaster; he wears a wide-brimmed white top hat with a golden snake and a red apple over golden spikes, which resemble a crown, and a red-lined and red-trimmed white popped-collared suit with eight golden buttons - his coat worn over a light red-and-white striped waistcoat with two golden buttons and a small, accessorized black bowtie. In "The Show Must Go On" his suit has red and golden epaulets, resembling those of a ringmaster.

He also wears a set of heeled black knee-high boots. On his left pinkie, he sports a golden ring which is presumably his wedding ring.

Lucifer is usually seen carrying an apple-topped black cane that matches his hat. Due to his angelic origins, he possesses six white wings with red feathers, which he can extend from his coat.

appearance (full demon): When he takes on his full demonic form, as well as displaying his wings, he displays a pair of red horns with an orb of fire between them and a thin crown resembling a snake with an apple above his hat. His eyes also change to have red sclera with yellow pupils. He also has a black tail with spikes that end in a triangular tip with a red heart at the center.

Eyes also appear on the inside of his coattails, and a similar eye also appears on his bowtie. In addition, his entire body gives off a light white glow.

personality: Despite his status as the ruler of all of Hell, Lucifer possesses a grandiose and dramatic nature, acting very over-the-top in most situations. He switches between being silly and theatrical and awkward and melancholic. Like Charlie, Lucifer is ambitious in his beliefs. According to the "The Story of Hell" book Charlie reads in "Overture", Lucifer was an idealistic dreamer whose desire to gift humankind with free will led to the accidental creation of Hell and the subsequent banishment of it caused him to give up his dreams. After he and Lilith separated, Lucifer went into isolation and fell into depression. He coped by crafting and hoarding tons of rubber ducks, spending years in his home. This obsession also causes him to become estranged from his daughter, to the point where he barely calls her at all and thinks she does not want to talk to him.

Lucifer is often times careless and doesn't think about what he says, even appearing clueless at times. For example, when confronting Adam, Lucifer misworded a verbal threat as an innuendo instead and smiled proudly afterward, and when Charlie corrects him, he forgets what he said. In his first meeting with Vaggie, he calls her "Maggie" right after being told her name. Additionally, even with his monumental position, he is rather socially awkward, for example, trying to connect with Charlie by excitedly bringing up that they both like girls.

However, he is not afraid to fight or get violent, as shown when he fearlessly battles Adam and beats him up violently. In the process, he is unafraid to act cocky and successfully irritate Adam by reminding him about his failure with Lilith, as well as suggesting he slept with Eve. Lucifer shows more intimidation prowess when he orders Lute to "take her 'little friends' and go home". Even so, he adds "please" politely, showing his generally refined manner.

As a father, he falls short of expectations. Although he loves Charlie dearly, he seems to be preoccupied with his own problems. He rarely calls her, and when he does, it's usually because he's bored or needs something. When Charlie reached out to him for help in setting up a meeting with Heaven, he was thrilled to hear from her. However, he couldn't recall where she was or what she was doing, even though she had shared her passion project, the Hazbin Hotel, with him months ago. He also wasn't aware that Charlie was dating someone, or that she was attracted to women. This indicates that, despite his love for Charlie, he doesn't communicate with her and hasn't built up a relationship with her, though it was shown that Lucifer was much closer to Charlie in her childhood, even being the one that inspired her to pursue her dreams and passions, only becoming more distant in Charlie’s adulthood.
