Vicky, also known as Vicky the [evil] Babysitter (voiced by Grey DeLisle), is a 16-year-old babysitter and the main antagonist in The Fairly OddParents. Vicky lives with her mother, her father, and her little sister (Tootie). Selfish, evil and greedy, she has few friends and enjoys money, torturing children, watching television and making the world miserable especially Timmy. She is a member of a dark society known as B.R.A.T.(Babysitters Raging Against Twerps) as said in the episode "Frenemy Mine." She has been shown to be accepting of her own cruelty, and that the only reason she is mean is because she was mistreated as a child by her own babysitter. In the episode "The Switch Glitch", Timmy, wanting to get revenge on Vicky, wished that he were her babysitter and regressed her to the age of five, he then gave her a taste of her own medicine. This backfired when Cosmo and Wanda were reassigned to her. One episode shows Vicky's ancestor being a sister of Ghengis Khan. In Wishology, she teams with Timmy to save everyone from "The Darkness" (in return for $20 from Timmy).

She is Tootie's older sister. Despite her love of torturing him, Timmy does not want Vicky to leave (he's had several chances to let her do so) since she is the main reason he received Cosmo and Wanda in the first place. Nonetheless, Timmy has shown to relish the thought of Vicky being replaced or fired and often attempts to get his parents to do so. She enjoys firing truth serums at Timmy to learn about his fears. Vicky is referenced in Sharon Lamb's book Packaging Girlhood: Rescuing Our Daughters from Marketers' Schemes, where she is referred to as "the mean girl/kid in the toon".[2]

Vicky served as the primary antagonist of Channel Chasers and in the console version of the video game The Fairly OddParents: Breakin' da Rules
