My daughter had pretty little clovers on her cheeks, and the cutest tail in all of Mewni
―Eclipsa Butterfly

Meteora Butterfly (better known as Miss Heinous) is the tertiary antagonist of Star vs. the Forces of Evil. She was the headmistress of St. Olga's Reform School for Wayward Princesses and is the Mewman/monster hybrid daughter of Queen Eclipsa.


Before she was born, Meteora's mother was wed to a Mewman king, but was already in love with a monster with red skin, white hair, and four eyes. Eclipsa later eloped with this monster and gave birth to Meteora, becoming the first Mewman/monster hybrid. Because she was part monster, the Magic High Commission saw Meteora as a threat to magic and Eclipsa's ex-husband, King Shastacan, did not want anything to do with her. She was replaced by the Magic High Commission with a peasant girl named Festivia and all record of her was erased from the Royal Archive.

At some point over the next three hundred years, Meteora lost all memory her heritage. Her name was changed to Miss Heinous, and at some point became the headmistress of St. Olga's Reform School for Wayward Princesses, where she "reformed" rebel princesses into "proper" princesses with no individuality. However, she would lose control of the school when Marco Diaz and Star Butterfly rallied a rebellion while trying to rescue Pony Head. After that, she swore revenge and sought to destroy them both at all costs. Meteora would not regain memory of her real name and heritage until she rediscovered her old nursery in an old Monster Temple, where Star was hosting a party to celebrate the unity of Monsters and Mewmans.
