This picture should explain everything! - Spongehouse
Their are so many things wrong with this cartoon. Too many annoying characters, flashing lights in your face, and too many fart jokes. This character is so annoying in every episode - YoshiApple

3 Chloe Carmichael - Fairly Oddparents
She is so extremely bad, idiotic, had the IQ of a dead animal, and is virtually a waste of space. I would like to know what the writers were smoking when they thought up the concept of her. - PageEmperor
I thought only the kids who had rough lifes got fairies. If that's the case than this waste of a character doesn't need fairies as her life already seems perfect without them - Spongehouse
Chole is the perfect example on how not to write a character, a character needs to have flaws in order to make them more relatable, interesting and allow for more character development, making them completely perfect or in this case a Mary Sue is just lazy and people aren't going to care about a character who's perfect with no real flaws. - egnomac
