Vicky (The Fairly OddParents, seasons 6-10)

Vicky is one of the two main antagonists (alongside Denzel Crocker) in The Fairly OddParents. She is a callous, sadistic, ruthless sixteen-year-old girl who babysits Timmy Turner. Her really menacing behavior towards Timmy is one of the reasons - if not the main reason - that he has fairy godparents, and most of his wishes involve getting revenge, or simply getting around her. Vicky is typically hired when Timmy's parents make a hasty getaway trip to one of their "adults-only" destinations, leaving Timmy in her cruel hands. Vicky is voiced by Grey DeLisle, who also voices Vicky's sister Tootie and many other characters. Vicky also had a cameo appearance in the extended version of A Fairly Odd Movie: Grow Up, Timmy Turner!, A Fairly Odd Christmas, and A Fairly Odd Summer, where she is portrayed in live-action by Devon Weigel.

Sadly, she got flanderized from season 6 until the show's cancellation while also having a severe reduction in screen time, despite still appearing in the show's intro and outro sequences.

Why She Was Intentionally Icky with a V and a Twerp

 * 1) Despite still appearing in the show's intro and outro sequences, she has much less focus in these seasons, as she is only put in certain episodes, to the point that Mr. Crocker has taken over her roll as the show’s main antagonist starting in Season 7.
 * 2) Her "evil babysitter" gag has been completely flanderized, as she has gone from a sadistic bully who enjoys messing with Timmy to a total psychopath who flat out tries to "destroy" him, almost as if she is God's Satan, which makes for unpleasant and unfunny attempts at providing humor. Before, the worst that Vicky would do to Timmy (or any child that she babysat) was property damage to pin the blame on him, force him to do chores, or even just simply leave him alone and watch TV, while her job entailed at keeping him in one piece, as she only saw her job as a means to make money, not to inherently hurt Timmy, while Timmy would often bend around her in the cleverest way possible. She also occasionally had a softer, kinder side to the point that she (temporarily) teamed up with Timmy in one episode from season 3. Now, she is only defined simply by her "evil" stereotype, to the point that other villains like Crocker, Foop and even Dark Lazer fear her for the sake of showcasing this fact.
 * 3) In "Open Wide and Say Aaagh!"(the episode that started her flanderization), she says she would not only yank out Timmy's tonsils, but also literally kill him. Yes, seriously.
 * 4) In "Vicky Gets Fired", after Timmy's parents saw the footage of Vicky erasing their videotape in which they were saving to use for their own reality show, they fire her from babysitting their son. She tries to find another job despite her already having other children to babysit, and in each job, she is fired, until she is so powerful, to the point she becomes "Dark Empress of Everything that Breaths", which is a poorly executed parody of Darth Vader from Star Wars.
 * 5) In "Frenemy Mine", after Timmy saves her life, which got her expelled from the "B.R.A.T.S." group, she warms up to Timmy, but in a bad way, as she begins aggressively stalking him to the point of not letting anyone else near him, which is not only inappropriate (especially since she's 16 years old and Timmy is 10 years old), but also weird and annoying. Isn't this something that her little sister, Tootie would do?
 * 6) * Speaking of Tootie, neither she nor Vicky are shown interacting with each other at all in these seasons, despite the fact that they are sisters.
 * 7) In "Scary GodCouple", after Foop becomes Vicky's fairy godparent (which is a continuity error by the way, as Foop is an anti-fairy and anti-fairies are not allowed to be assigned to children as they are evil), they proceed to terrorize all children in Dimmsdale.
 * 8) In some episodes, like "Fairly OddPet", "Dumbbell Curve", and "The Big Fairy Share Scare", she is just shoehorned in as a generic evil plot device for a brief scene or two.
 * 9) She is at her absolute worst in "Certifiable Super Sitter", where she actively tries to kill Timmy and Chloe Carmichael. She even tortures Timmy's dad, referring to him as the "man with the weird hat", who has also hit rock bottom in the same episode in which he is portrayed as a mentally disabled man child with poor vocabulary. Doesn't the man with the weird hat sound familiar to you?
 * 10) * Vicky and Timmy's Dad also seem to not know each other in said episode because the writers clearly wanted it that way.

Redeeming Qualities

 * 1) She was a better villain in the first five seasons, as well as the Oh Yeah! Cartoons pilot shorts.
 * 2) She is tolerable in some episodes, such as "Wishology!", "Mice Capades" and "When Losers Attack".
 * 3) She still gets her comeuppance for her antics.
 * 4) It's pretty much clear that Butch Hartman flanderized Vicky to make the audience and fans hate her so they will root for Timmy,  even in the last 2 seasons, sort of.
