Charlie Morningstar/History

Charlie was born in Hell to Lucifer and Lilith, the rulers of the realm. Growing up, Charlie tried to see the good in her home and people, despite witnessing the atrocities of the sinners and their victimization during the annual Extermination.

At some point in her early life, Charlie would become acquainted with the von Eldritch family due to her family's connections in Hell.

Charlie would be put off by Helsa von Eldritch's attitude and the two would eventually become bitter rivals. Charlie would enter a relationship with Helsa's brother Seviathan but for unknown reasons they would soon break things off.

Sometime before the pilot, she met Vaggie and the two became friends; this would eventually lead to a romantic relationship forming between them.

Before the pilot Charlie decided to open up the Happy Hotel in order to rehabilitate sinners as an alternative method toward overpopulation.

Upon opening the Happy Hotel, Charlie and Vaggie would try to find someone who would be willing to become the first resident of the hotel.

After spending some time searching, they came across Angel Dust prostituting himself on the streets. Charlie pays him to listen to their offer and is quite excited when Angel agrees to go with them and become the hotel's first tenant.

Two weeks pass, and after the most recent Extermination, Charlie, alongside Vaggie, go to formally introduce the Happy Hotel on Katie Killjoy's news show to the viewers and all of Hell; despite her promise to Vaggie, Charlie eventually decides to convey her idea via singing.

Unfortunately, her efforts backfire when everyone present laughs at the ludicrous idea of possibly rehabilitating a demon in Hell; furthermore, both Charlie and Vaggie are informed that their tenant Angel is currently part of a turf war with Cherri Bomb against Sir Pentious.

Charlie eventually becomes enraged by Katie's continued belittling and mocking of her and the two get into a drawn-out fight that is broadcast on-air; the resulting fight destroys much of the studio and during the chaos, Charlie sets Katie's co-host, Tom Trench on fire.

As they ride back to the hotel, Charlie sadly looks out the window and listens to both Vaggie and Angel yelling at each other over what happened. She eventually speaks up and tells Angel that what he did was wrong.

Charlie tries to maintain a positive outlook that there still is a chance it could work, but after trying to call her mother, begins crying at the realization that her endeavors and dreams might be pointless after all; she tells her mother in a voicemail that she has no idea on how to make her idea work and worried her father could be right about her.

As Charlie glumly thinks about what to do next, she hears a knock at the door; opening it, Charlie is both surprised and horrified to see The Radio Demon known as Alastor standing there.

Despite panicking and asking Vaggie what to do, Charlie does allow the demon to speak and is taken aback when he offers his assistance in running the hotel.

Knowing of Alastor's status as an Overlord, Charlie understandably asks why and is told he was simply bored and thought the idea of a rehabilitated demon was nonsensical yet entertaining at the same time.

Charlie thinks it over and is reminded by Vaggie that making any type of deal with Alastor would be a grave mistake.

She uses her position and family name to get Alastor to work for her but allows him to work as long as he desires at the hotel.

Upon seeing him bring in Niffty and Husk as employees, Charlie is immediately impressed with the changes Alastor has made and begins seeing this as a new start for the hotel.

Hearing an explosion outside the hotel, Charlie and the others watch in awe and terror as Alastor uses his powers to effortlessly destroy the ship and laser Sir Pentious was using.
