Vicky the Babysitter is a 16-year-old babysitter who tortures Timmy Turner, and is also one of Timmy's arch-enemies. She has no friends and enjoys money, tortures children, and watches television. 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 a babysitter. In the episode "The Switch Glitch", Timmy, wanting to get revenge on Vicky, wished that he was her babysitter and regressed her to the age of five, where 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, she would get $20 from Timmy.
She is Tootie's older sister. Despite her tortures, Timmy does not want Vicky to leave (he's had several chances of having 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".
Vicky served as the primary antagonist of Channel Chasers.
