Charlotte Magne, most commonly referred to as Charlie, is the Hell-born princess of Hell and the founder of the Happy Hotel. Despite what most of Hell thinks, she believes that redemption is possible for any and all demons and hopes that it will help with the betterment of the kingdom.

She shows strong compassion towards her friends and her people. She's naive and theatrical, while also bursting with passion. Charlie does everything in her power to make everyone happy and is determined to make her kingdom into a better place. However, she can be stubborn whenever something doesn't go her way. She also has a huge passion and love for musical theatre. Despite being sweet and naive, it doesn't make her a pushover or stupid.
It is shown throughout the pilot episode that Charlie also struggles with feelings of inferiority. While she is often striving to do better and make a difference for the betterment of Hell, she is prone to self-doubt and sulking whenever her plans fail horribly. She’s also known to "act before thinking".

Trivia
* Charlie is the only one out of the main cast to be an "original demon" due to being born in hell, and therefore not previously human.
* Charlie originally died in the 1830s, but it was changed to "born in Hell" during the show's development.
* She's never seen a human before. However, she thinks there's something magical in both humans and demons.
* The name Charlie Magne seems to be a pun on Charlemagne, the first emperor of Europe.
* When used as a surname in French Magne (short for Magnus) translates to "Great" or "the Great" meaning the Magne family would be "Charlie the Great", "Lucifer the Great" and "Lilith the Great"
* Charlie's favorite musicals would be Something Rotten, Legally Blonde, Cats, Funny Girl, and Chicago.
* Charlie has a rival named Helsa, who according to Vivziepop in an Ashley Nichols live stream, will definitely be in the series in the future.
* Charlie's orientation and relationships have been explored: Charlie was confirmed to be bisexual based on the colors of the bisexual pride flag appearing in a tweet from Vivienne Medrano's account "VivziePop". Charlie has an ex-boyfriend, Seviathan, who is shown to be Helsa's brother, as seen in the portraits in the background of the hotel. Vivziepop describes Charlie and Vaggie's relationship as to that of Jack Skellington and Sally's relationship from The Nightmare Before Christmas. When asked on who she thinks fell for the other first (Charlie or Vaggie), Vivziepop said that she doesn't actually know and feels like the way she has their relationship figured out was that they were really good friends right away and she thinks it was still during the time and kind of before the events of the pilot and it might even happen before the events of even the things Viv herself is planning before the pilot. It also happens pretty far ahead of the events of a lot of stuff.
* According to Vivziepop, Charlie's favorite book would be Harry Potter.
* Vivzie also said she would like books that have happy endings and strong characters.
* She also said that she would love teen adventure books like Percy Jackson, Harry Potter, and Hunger Games. She also said she would be very basic in her young adult novel.
* Charlie's attitude towards a lot of the patients at the hotel is to kind of treat them like children. She can use them as wayward teens that need help and need writing and discipline. She has a little bit of an immature view of it, so her punishments are more akin to "you need a timeout", instead of a more serious "you need therapy". For instance, Charlie would punish Angel like a child
* Charlie isn't fully aware of her position (as the princess), being far too trusting of people (thus causing Vaggie to always be on guard).
* According to Vivziepop, Charlie takes very much after her dad.
* When asked on what kind of things Charlie and Vaggie were doing before opening the hotel, Vivziepop said that she doesn't want to answer this because she would actually really love to explore this in comics. She has a lot of ideas for kind of prequel-esque stories (specifically more about Charlie and Vaggie a little bit before the events of the story) because there are some things that they could definitely tell in the show but there are some things that might be even more satisfying that she wants to tell in the comics.
* According to Faustisse, Charlie may have a long lifespan but that does not make her immortal. And that both Charlie and her mother, alongside Alastor, are fans of pineapple on pizza.
