Vendetta: (Voiced by Aglaia Mortcheva) Vendetta is a sociopathic, narcissistic and histrionic young girl with the power to create "fiends" with a book of recipes. She is moss green and wears pigtails that tend to fly up when she yells. She constantly squints her eyes for emphasis. She spends her time reading magazines and tormenting the other children in her school with her monstrous creations. She uses her dangerous fiends to get what she wants, such as her constant assistant Grudge who helps her give out physical punishment. She develops a one-sided rivalry with Charlotte, and often attempts to kill her. Vendetta almost always uses fiends for her attempts, but she has also done methods like tricking Charlotte into wearing concrete shoes and walking off the edge of a pier. She despises music, to the point of being hurt by it. Her diet consists of almost entirely beef jerky, clams, and grape punch. She speaks in a thick Bulgarian accent and has somewhat broken English. Vendetta appeared in every episode except for episode 14.
