the king of hell;
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 often switches between being silly and melancholic. Like Charlie, Lucifer is ambitious in what he believes in. According to the storybook that Charlie read, Lucifer was an idealistic dreamer whose accidental creation of Hell and subsequent banishment to it caused him to give up his dreams. After he and Lilith separated, Lucifer went into isolation and fell into a depression. He coped by crafting and hoarding tons of rubber ducks, spending years in his home. This obsession also caused him to become estranged from his daughter, to the point where he barely calls Charlie at all.
As a father, he falls short of expectations. Although he loves Charlie dearly, he seems to be preoccupied with his own problems. He seldom calls Charlie, 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.
Lucifer dislikes the Sinners of Hell and describes them as "violent, destructive psychopaths, hellbent on causing as much pain and destruction as possible". According to him, they are all "the worst" and he does not believe they can be redeemed. Although he understands his daughter's interest in rehabilitating Sinners, he is cynical about the idea of trying to save any of them and feels broken after realizing the consequences of giving humanity free will. Since Heaven was so unwilling to listen to him in the past, he does not want Charlie to go through the same thing. However, Charlie still manages to convince him to arrange a meeting in Heaven for her and Vaggie, which helps Lucifer regain faith in her plans.
Lucifer is fiercely protective of Charlie, as seen when he threatens her bodyguards, Razzle and Dazzle, and when he displays jealousy toward Alastor, whom he sees as a rival for Charlie's affection.
adam, I wasn’t expecting you. I didn’t think that we would end up together. The single most extraordinary thing I’ve ever done with my life is fall in love with you. I’ve never been seen so completely, loved so passionately and protected so fiercely. I love you, and that’s the beginning and end of everything.
