Charlotte (Amy Winfrey) is a blue girl from Vermont, and the main protagonist in the series. She's generally oblivious and usually ends up destroying Vendetta's fiends without even trying. Plus, she thinks Vendetta is her friend.
Charlotte is light blue in color. She has a bow in her hair, she is only seen wearing blue dress and has light sky blue eyes, and her tongue is also a darker shade of blue.
Life in Clamburg
On her first day at the school, she is fascinated by Vendetta, a green girl who Charlotte thinks is "nice" and has a "pretty name". Charlotte believes she and Vendetta are best friends and does not realize that Vendetta hates her and tries to "destroy" her with fiends; monsters only Vendetta can make, which are the reason why everyone is afraid of her. Vendetta usually makes fiends to destroy Charlotte, but somehow Charlotte always finds a way to make the fiend friendly or do useful things. Charlotte is going to have to try harder to bring cheer and happiness back to Clamburg.
Charlotte attends Mu Elementary School in classroom four with Mr. Milk teaching. She sits next to Marion, a nervous light blue girl. Charlotte's personality antagonizes Vendetta, and has even shown to be a danger to Clamburg in general in a few occasions. Many scenes of her innocent antics are designed to provoke sympathy for anyone who is involved in the occasions, many times driving the victim to be horribly frightened.
Charlotte has a pet hamster named Buttons and a scissors fiend named Buttons 2. Charlotte's grandmother Charlene is just like her, only older. They are both always happy and see everything as friendly.
Charlotte could be described as too friendly; it is nearly impossible for her to get angry as she sees everything as friendly and kind. She is very naive and believes Vendetta is her best friend. Vendetta is extremely annoyed by Charlotte, as she is the only one in Clamburg that does not obey her, and she is annoyed by Charlotte's cheerfulness and constant singing. Due to Charlotte's cheerful nature, she never notices that Vendetta is evil or that she is trying to destroy her, nor that she actually hates her. Her careless, innocent personality makes her ignorant to everything evil.
A sad side of Charlotte was not seen until Maggie read a poem about a lost kitty, which caused Charlotte to fall into depression, and thus did not feel like singing. However, using her creative imagination, she came up with a solution on how to save the lost kitty, and went back to being cheerful again.
She almost always make up a song on the spot when something interesting is happening, such as when she is swinging or a song about Vendetta. She also likes to sing songs about such things as being small, No. 2 pencils and cheese.
In every episode, it is seen how Charlotte annoys Vendetta with her songs and happiness. Vendetta hates songs, and most of all, Charlotte. She always makes fiends for her, which Charlotte thinks are gifts of friendship. Somehow when Vendetta unleashes a fiend onto Charlotte, Charlotte always finds a way to make the fiend friendly. Vendetta often throws things at Charlotte, Charlotte always thinks that Vendetta is giving her these items. One instance when this occurred is when Charlotte brings in a rock for show and tell that she tells the class Vendetta gave her. Vendetta yells that she threw it at Charlotte. Vendetta is also often times attempting to kill Charlotte with various schemes and fiends. Charlotte usually thinks fiends are cute or just doesn't notice them. Vendetta rules over the gloomy town of Clamburg though Charlotte just assumes Vendetta is another person that lives in the town with no more significance other than being her best friend. She has no idea that Vendetta hates her.
As her pet hamster, Charlotte loves Buttons, calling him "her favorite hamster in the whole world" and is frequently seen playing with him with her toys. However, she unknowingly terrifies him at times, often treating him like a plaything and putting him in situations where he is danger of being attacked by one of Vendetta's fiends.
- The creator, Amy Winfrey, provides the voice of Charlotte. Her voice is slightly lower in the television series than in the web series. Winfrey provides the voice of many other characters on the show, including Charlene, Marion, Buttons, the Giant Kitty among others. At first, Winfrey felt guilty casting Aglaia Mortcheva as the evil character, Vendetta. They tried Mortcheva as Charlotte, but it did not work out. Mostly because of her Bulgarian accent and that she hates singing, when Charlotte sings frequently.
- She is somewhat similar to Dib Membrane from another short-lived Nickelodeon series, Invader Zim. Both wear blue, have a missing parent(s), and are always chasing a character who is green (Zim/Vendetta).
- The only things she dislikes are strawberries and moose. She doesn't like strawberries as seen in "Birthday" when she finds one on her birthday cake, but it is unknown why she dislikes moose.
- The only times she is actually seen sad is when she hears Maggie's poem in "No Singing", telling Vendetta about her parents in "Parents", and when Vendetta is getting along with Marion in "New Best Friend".
- During the creation of the webseries, Charlotte had different character designs. One design had a more stylized dress and a different style of hair, while the other looked a bit more similar to the final design but with hair beads.
- In the original web series, Amy's Charlotte voice is rather high-pitched. But when recording for the Nickelodeon series, she uses her normal voice then it's high-pitched in the editing room, but it still sounds noticeably lower than her voice in the web series. This is shown in the Behind the Scenes of the TV series.
- She was originally going to be voiced by Aglaia Mortcheva. But according to the background information above, it did not work out.
- There has been a theory about why Charlotte doesn't seem to care about dying or Vendetta planning on killing her. It might be hinting that she wants to see her parents again when she says that they're in a "better place", subtle meaning they're in heaven, as claimed in "Parents".
- Despite her dislike for strawberries, her name refers to a dessert that can be topped with strawberries.
- Charlotte is the only character to appear in every episode of the web series.
