Mindy is one of the recurring antagonists of The Grim Adventures of Billy & Mandy. She is very typical antagonistic and cruel cheerleader-type villainess who has an intense rivalry with Mandy and goes as far beating nerdy people like Billy and Irwin. She however is neither particularly bright nor especially open-minded leading to her being easy to manipulate. It is strongly implied that she has inferiority issues about her appearance and her social status which is why she goes as far as trying to incinerate Mandy when she takes her place in "The Longest Yard". Her vain yet narrow-minded personality was taken advantage of Bun Bun in the Underfist movie.
She is also the secondary antagonist of the Halloween special Underfist: Halloween Bash.
She is voiced by Rachael McFarlane, who is also the voice of Eris.
Mindy has ginger colored hair and freckles on both her cheeks. She wears a typical school uniform which includes the blue skirt, white button-up shirt and pink Mary Jane shoes, she can be seen without her school uniform in some episodes.
Mindy is a snobby, stuck-up, selfish, mean, rude, and spoiled stereotypical popular girl who is the arch-nemesis of Mandy. There are also times when Mindy has actually tried to kill Mandy.
She is also shown to be able to hold a grudge for a very long time, as she hates Mandy for rejecting her when they were much younger; however, she can put aside her hatred towards Mandy if it means survival, an example being in Wrath of the Spider Queen, when she helped Mandy fight the spiders.
Despite being mean and arrogant like Mandy, she is not as smart as her and can be considered an airhead, for example is that she thinks that Paris and Toronto are countries and that Africa is a city.
Mindy looks similar to her other counterparts which consists of Dee Dee from Dexter's Laboratory, Cream the Rabbit from Sonic the Hedgehog, Darwin Watterson from The Amazing World of Gumball (before he existed since 2011), Princess Morbucks from The Powerpuff Girls or any type of characters that are orange and they use the same palette (like CatDog from the same name of their show or Lazlo from Camp Lazlo) except for Dee Dee because her hair is yellow but she does look similar to Mindy due to the fact that they both wear pink shoes.
Mindy's personality is very similar to Nina Harper from Braceface and Mandy from Totally Spies!.
