Marie Curie is a horribly deformed clone of Marie Curie, due to the mutated DNA of her clonemother's corpse (Marie Curie died of radiation). She is the president of the school's dance troop, the Solid Gandhi Dancers.
Marie has a crush on Gandhi. When she found out that he had A.D.D., she tried to warn him to leave town before something horrible happens. She was disgusted with Gandhi and Abe kissing, but got past that. She has also laughed at the idea of girl playing basketball, making her a self-deprecating misogynist. Despite this, she wanted Joan to shoot free throws in the homecoming basketball game against GESH (Genetically Engineered Superhuman High). For the prom she tried to ask Gandhi to go with her, but because of Gandhi's 'GFK' acting she rejected him, calling him an ass. Surprisingly, she and Gandhi end up together in a platonic love relationship because they were still young for something serious. Sadly, she was with everyone else that got frozen in the meat locker, standing next to Gandhi and discovering what have JFK and Joan had done.
She likes to dance and even professional dancers can learn from her. Marie is very sweet, helpful and active in school.
