Lucifer Morningstar!

Lucifer is a slender-figured humanoid fallen angel who sports a close resemblance to his daughter, Charlie - having the same white skin with rosy-cheeks, blonde hair with thin light coral streaks on the thicker, paler-blonde highlights, and eyes with light yellow sclera, though with red irises with very small pupils that are only visible within close-ups.

Unlike Charlie, his mouth is full of sharp teeth, and his hair is cut short and has been slicked back in a ducktail hairstyle with one tuft sticking out. In addition, his tongue is forked and pupils slitted like a snake, and his eyelids are light purple. He is shorter than his daughter, though not by a large amount.

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 and dark grey gloves,which are forearm-length in "The Show Must Go On". On his left pinkie, he wears 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. Personality Despite his status as the ruler of all of Hell, Lucifer possesses a glorious and dramatic nature, acting very over-the-top in most situations. He switches between being silly and theatrical to awkward and sad. 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 to it caused him to give up on his goals. After he and Lilith separated, Lucifer fell into isolation and deep melancholy. Coping by crafting and hoarding tons of rubber ducks, spending years at his home alone. This obsession also causes him to become estranged from his daughter to the point where he barely calls her at all, depressively thinking she does not want to talk to him.

Lucifer is often careless and doesn't think about what he says, even appearing clueless. 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 politely adds "please", 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; 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. However, 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.

While he is the King of Hell, Lucifer hardly rules over his subjects and leaves them to their own devices. As a result, his name (and, by extension, Charlie) carries little weight. While the denizens of Hell recognize that he is a powerful force to be reckoned with, they seem to know that little, if anything, would make him show up. Lucifer dislikes the Sinners of Hell and describes them as "violent, destructive psychopaths, hellbent on causing as much pain and destruction as possible". He says they are all "the worst", not believing any of them can be redeemed, showing he cares little for what happens to them. Despite his disapproval of Sinners, Lucifer hints that he regrets his role in ever giving them free will due to what they had done with it and the consequences that came from this.

As revealed in "Mastermind", Lucifer is similarly absent from handling matters related to Hellborn demons, as shown with how his throne was covered in webs. With his absence, Satan in particular took the lead as Hell's main ruler and lied that he was the true King of Hell and ruled it long before Lucifer had "fallen" into it.

Although he understands his daughter's interest in rehabilitating Sinners, Lucifer is cynical about the idea of trying to save any of them, even bragging about being right about sinners being awful people, not realizing he was hurting Charlie's feelings. However, he stated that Charlie doesn't know that when he tried to make his own dreams a reality before, they were too hard to defend,[14] and since Heaven was so unwilling to listen to him in the past, he does not want Charlie to go through the same thing. Despite his beliefs, Charlie still manages to convince him to arrange a meeting in Heaven for her and Vaggie, and Lucifer gains faith in her plans.

Lucifer is fiercely protective of Charlie, as seen when he subtly threatens her bodyguards, Razzle and Dazzle, that they had better be doing their job protecting her. Later, when Alastor began rubbing in his failings to be a proper, supportive father to Charlie and her dreams and implying he had taken Lucifer's place as Charlie's father figure, Lucifer displayed jealousy toward Alastor, whom he began to see as a rival for Charlie's affection and became insecure about his familial bond with her. In "The Show Must Go On", he arrived late, but joined the fight against Adam and the Exorcists, helping Charlie defeat them. This protective nature is shown again when at one point, Adam tries to strike both Lucifer and Charlie from behind for them to block his blow and send him flying into the dirt. Dropping the mocking attitude he had previously given to Adam during their fight, Lucifer then proceeds to angrily berate Adam for threatening him and Charlie before pummeling him within an inch of his life, only stopping at Charlie's insistence. Immortality - As told in "Overture", Lucifer has existed since before the creation of the world, meaning he is at least thousands of years old and presumably unable to die of old age, and as demonic royalty is presumably biologically immortal and only able to be killed by angelic weaponry. Angelic power - Lucifer possesses immensely powerful angelic magic which holds sway over the demonic power of his contemporaries.[3] Pyligenesis - In "Dad Beat Dad", Lucifer was shown to conjure portals as a means of instant transportation, which he is shown to use when transporting other demons. These portals manifest as rings of sparkly light, similar to the portal that took and removed Charlie and Vaggie in "Welcome to Heaven" from Heaven, indicating that this ability is derived from his angelic powers. Demonic transformation - Lucifer can assume a more fearsome and powerful demonic form. Immense strength - Lucifer's physical strength is beyond exceptional, as he barely put any effort during his fight with Adam, mocking the first man, when the Angel managed to defeat both Charlie and Alastor in brief skirmishes. He also gave really tight hugs to Charlie and Vaggie to the point where they had slight trouble breathing. Flight - Lucifer can summon six angelic wings on a whim, with the size of his wings varying throughout the show. Life manipulation - Lucifer created Razzle and Dazzle for Charlie.[15] Teleportation - Lucifer can instantly teleport himself from one location to another. He does this by enveloping himself in a swirling fog of deep red smoke with sparkling, golden glitter. Shapeshifting - Lucifer can shapeshift into a wide variety of animals, as seen in "The Show Must Go On", he took the forms of a snake, a goat, a bird, a horse, and an octopus. When he shapeshifts, he still keeps some of his traits, like color scheme, blush, hair, bowtie, and top hat. Conjuration - Lucifer seems to be able to create virtually anything he desires with a simple flick of the wrist. This includes, but is not limited, to clothing, puppets, instruments, large fountains of champagne, and mountains of caviar. Hydrokinesis - During the song "Hell's Greatest Dad", Lucifer is seen throwing a yellow-colored liquid, presumably apple juice or champagne, at Alastor. Pyrokinesis - Like his daughter, Charlie, he also has the power to manipulate fire at will. When fighting Adam in "The Show Must Go On" he is seen creating balls of fire out of thin air at will. Fire breath - He can make fire come out of his mouth when he speaks. Musical talent - Similar to his daughter, Lucifer partakes in singing.[16] Instrumental talent - Additionally, he is shown to be quite a skilled fiddle player during his musical duet with Alastor. Lucifer also showed that he could play a violin and an accordion to a minor degree. He can also play the trumpet, shown for a brief moment at the beginning of the Hell's Greatest Dad. Craftsmanship - Lucifer spends his time making rubber ducks with various gimmicks, such as flipping backwards and spitting fire. Hand-to-hand combat - He is adept at physical combat, as he effortlessly held his own against Adam in "The Show Must Go On".
