*Violet Vanderfleet is a villain who appeared as the main antagonist in "Evil Bouquets Are Sooo Passe" and "Baddies on a Blimp". She is a botanist and vindictive person after being dumped by all her boyfriends.

An accomplished botanist, she created a hybrid of poisonous flowers called the ”Viola Vanderfleetus” to destroy the male half of civilization because of her own failed romances and because of her belief that there are, in her words, ”a lot of angry, hurt women out there” who ”all want revenge”.

Her madness began after her boyfriend dumped her for another girl 5 years ago. When Sam asked why she zombified the other guys, she replies that they all dumped her as well.

At one point, she offered Clover a chance to help her, as she sensed Clover's jealousy at the fact that Samantha was having a study date with Clover's ex-boyfriend, Fernando. However, Clover refused. Her plan goes haywire when one of her plants catches a strand of her hair and attacks her. She is arrested and taken to the WOOHP Prison.

In addition to her knowledge of plant biology and chemistry, she is able to pilot a plane and is a skilled combatant, easily dodging and countering the girls' attacks. She effortlessly nearly took down all three of them by herself, though the girls may have been exhausted from the previous encounters with her plants.

In ”Baddies on a Blimp”, Violet is one of three prisoners to be transported to WOOHP Island via the WOOHP Blimp. However, a computer glitch frees her and the other prisoners, and they take over. She wants to cause a worldwide allergy to love attack with her sneezing peonies.

Violet seemed to have a strong fantastical view on love judging by her extreme reaction towards being dumped. She now uses her skills in botany to create plants that obey her every whelm. Scorned and full of hate, Violet now harbors distaste for love and exhibits intense envy towards those in love. She uses her plants as a means to make all men pay for the one man who broke her heart.*
