Eric and Claire/Claire the Ghost

Claire is the main protagonist alongside Eric McEdderson of Eric and Claire.

Personality
Before the events of the first part of "Claire", after her death caused by a tornado back in 1964, she was extremely lonely and depressed since no one was there for her anymore. After the first part, however, she is now glad to finally have someone with her. She is also shown to be kind and caring towards her friends, especially Eric.

Like Eric being protective over Claire by making her wear her human disguise when she is around someone that is not him or his friends, Claire can be protective over Eric whenever someone tries to hurt him and his friends. In Llamy the Llama, Claire notices Llamy the Llama almost trying to kill her friends, so in order to stop him, she possesses Llamy the Llama's costume and beats the actor's ghost inside.

Claire doesn't talk normally. Instead, she talks in her own way, which is called "Claire-nese" by Brandon and Michael. Like if she says "Hi" or "Bye", she'll say "Hmm!". If she says something like "My Name is Claire", she'll say "Mmm Numm im Clamm!". She doesn't do that all the time. Sometimes, she just writes on paper of does sign language when she doesn't speak "Claire-nese". In Claire's Long Lost Brother, it was revealed by Billy the Ghost that she has a voice disorder that makes her talk like this.

Appearance
Claire has a light gray body with black eyes. Her most recognizable physical trait is her unique, triangular-shaped hairstyle.

In her human disguise, she is shown to be a light-skinned, short, "teenage" girl with black hair, a lime shirt with a dark green cat face on it, jeans, and black sneakers.

Trivia

 * Many E&C fans appear to compare Claire to Casper. However, some fans compare her to non-ghost characters like Snoopy and Pikachu, possibly due to her "cuteness" and the fact that she doesn't talk like a normal human, but rather in a different way like Snoopy and Pikachu do.
 * The funny thing is that unlike other cartoon ghosts, Claire can do stuff that they can't do. For example:
 * She is shown to be able to eat and drink without any food or drinks going through her and instead into her stomach like how food and drinks gets consumed by a living human.
 * Claire is actually prone to illnesses unlike most ghost characters. This is proven in Emily's Flu.
