Character
;Voice At first, Winfrey felt a little guilty for casting Mortcheva as the evil character. They tried her as Charlotte, but it did not work out. ;Personality Vendetta spends her time torturing the other children and using her giant bear-like hamster, Grudge, to get what she wants. She is narcissistic and rather histrionic, filling her home with pictures of herself, over-dramatizing anything negative that happens to her and desiring to be feared and respected. She constantly tries to destroy Charlotte, but her schemes are always foiled by Charlotte's kind obliviousness. She only eats clams, beef jerky, grape punch, and onions. She hates several things that are mentioned throughout the show. More often than not, she would use the word "stupid" to describe something she detests, such as Charlotte, Charlotte's grandmother, or a fiend who disobeys her.
