Lucifer Morningstar/History

Aside from his position as Hell's ruler and being the husband of Lilith and the father of Charlie, little is known of Lucifer.

The show's creative team, however, has described him as being "goofy" and similar to Willy Wonka in ways.

He is also said to have a great love for music, being a talented musician himself. At some point, he also started a successful theme park called Lu Lu World that proved to be quite popular with the denizens of Hell.

Though he plays no role in the pilot, Lucifer is referenced and alluded to many times. Shadowy figures resembling him appear during the opening song "I'm Always Chasing Rainbows".

Notably, during the verse "Why have I always been a failure", his shadow materializes behind Charlie; this possibly implies that he is disappointed in her decision to start up the Happy Hotel.

Later during the fireworks display, four demons are seen watching from a window, one of which is a red-eyed silhouetted figure wearing a large hat and holding a distinctive cane, features that strongly suggest it is Lucifer.

His visage is later glimpsed in several background images of the Happy Hotel, most notably a family portrait that catches Alastor's attention.
