Lucifer Morningstar/Relationships

Charlie Morningstar
Charlie is Lucifer's daughter. In the pilot, it is implied that Lucifer does not believe in his daughter's plan to rehabilitate sinners. When Charlie calls Lilith to talk about her failed interview, she says, "I think Dad was right about me." Nonetheless, Charlie did take his words of dealing with demons to heart, such as Alastor.

As shown in "Dad Beat Dad", Lucifer cares for Charlie deeply and loves her very much, but due to his personal issues, he has trouble expressing his affection for her. Still, Lucifer wishes to spend more time with Charlie and desires to feel close to her. When Charlie invited him to her hotel, he was delighted and took it as a sign that she wanted to spend more time with him.

Lilith
Though little is known about their actual relationship outside of being married, they are revealed in "Dad Beat Dad" to have separated.

Razzle and Dazzle
Razzle and Dazzle were gifted to Charlie by Lucifer during her childhood to act as her personal bodyguards. Razzle and Dazzle are protective of Charlie and the rest of her family.

Alastor
Lucifer does not seem to know Alastor before meeting him in "Dad Beat Dad", as he asks who he is and states that he does not know him from his radio broadcast. However, the two immediately do not get along. Shortly after Charlie introduces them, Lucifer suggests that Alastor is a has-been and insults the hotel's name. In response, Alastor cusses him out. Additionally, Lucifer would show jealousy towards Alastor when the latter began showing off his "deep" bond with Charlie. This caused Lucifer to become increasingly insecure about his relationship with his daughter, and he began to compete with Alastor for her attention.

Mammon
Mammon considers Lucifer his "friend". Whether Lucifer affirms this friendship with Mammon is unknown.
