Charlotte Magne, most commonly referred to as Charlie, is the Hell-born princess of Hell, the founder of the Happy Hotel and the main protagonist of Hazbin Hotel. She, despite what most of Hell thinks, 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. So much so that she says herself that she communicates more information through song.

Despite being sweet and naive, it doesn't make her a pushover or stupid. When Katie Killjoy kept ruthlessly mocking her idea, Charlie stole her pen and called her a bitch. Even when Katie turned into her demon form, Charlie began to fight back and even set Tom Trench on fire. When Alastor offered to make a deal with Charlie by a handshake, she refused and used her status by ordering Alastor to help her with the hotel but it's for as long as he desires; which he agrees to. She is also not above letting a few cuss words slip. Charlie also knows that not all demons are redeemable since she admits that she knows how evil Alastor can be and most likely not going to change for the better.

It is shown throughout the pilot episode that Charlie also struggles with feelings of inferiority, calling herself a failure in the opening song sequence and being seen as such by some of Hell's inhabitants. 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 when her plans fail horribly.

She’s also known to "act before thinking". Like before her interview, she made a list of her plans but it just said random stuff like "dolphins kisses and high five." Even during her interview, she thought singing her song "Inside of Every Demon is a Rainbow" would help the people understand her plan better. Only to be devastated to learn that her plan wouldn’t automatically be accepted and was laughed by everybody in the news station. She even admits during her voicemail to her Mother that she doesn’t know what she is doing or how to make her plan for reforming demons can work.

Try to sound like the show. I want no changes.
