Wanda

Wanda Venus Fairywinkle-Cosma is a main character in the series, who is one of Timmy's fairy godparents, alongside her husband Cosmo, and her son Poof. Unlike her husband, Wanda tends to be more responsible and is reluctant to grant dumb wishes, but is usually obliged to grant them anyway or Cosmo grants them instead.

Character
Bright and compassionate, Wanda loves her current godchild Timmy just as much as she loves her son, Poof, and husband Cosmo. She is also the most responsible out of the bunch. In "Fairly OddBaby", it is revealed that Cosmo was the last baby born in Fairy World (before Poof), implying that Wanda is slightly older than him. She is often blamed for the misadventures that she and her family get themselves into by Jorgen von Strangle, who states she should take care to watch them better because of Cosmo's dangerous stupidity. She always loses to Cosmo when it comes to second guessing what Timmy wants to do, usually because Timmy wants to do something fun or destructive. She was apparently very popular in high school.

Wanda is usually seen as more intelligent as her other half, Cosmo, and this is parodied to the extreme in Anti-Wanda and Anti-Cosmo, who are exact opposites of Cosmo and Wanda. Anti-Cosmo is Wanda's equivalent and is an evil genius, while Anti-Wanda is Cosmo's equivalent and is the dumber one who often foils everything. Despite this, however, Wanda can be just as guilty as her husband in making errant wishes without reading Da Rules first, causing Timmy to get into trouble or into a situation that cannot easily be unwished. Usually though, it is Wanda who is the sole voice of reason when Cosmo and Timmy are about to make a dumb wish.

Wanda is originally described as daffy, as was her husband, and holds a wicked temper. She is often defined as an extremely nagging woman by many characters on the show.

Description
Wanda has pink hair and pink eyes. Like all fairy godparents, she has a crown floating above her head, carries a magic wand, and has fly-like wings which enable her to float. Her hair has always been shown to have a distinctive swirly front, although when she was younger she had a pony tail in the back; and when she was turned into a teenager by a magic carwash, her hair went completely straight. She also wears a yellow shirt and black pants. She is the most intelligent of the group, since Cosmo is a moron and Timmy can fall into immature decisions. Often times her cautious and worrisome attitude results in her being perceived as a "nag" by Cosmo, and he often use this to tease her. In the episode Spaceman Poof, she also uses her swirly hair to curl it around people and throw them!
