Queen Luna is the queen of the planet Solaria. She is Stella's mother and also the ex-wife of King Radius. In the comics, she is seen with her new lover, Allan, (whom Stella is not fond of) at parent-teacher meetings. She constantly tried to get her daughter to be kind to him and bond with him as a new family member. Stella eventually opened up but was still very bitter about her having a new boyfriend. However, since we never see the new boyfriend in the series, it is possible Luna is not dating him anymore, or just because the comics are not canon with the series.
