Marie Curie is a clone of Polish chemist Marie Curie. Due to the radiated DNA of her clone mother's corpse, she suffers from several physical deformities. She is the president of the school's dance troupe, the Solid Gandhi Dancers.
Marie has a tall, generally large build, making her possibly the tallest female student at Clone High. She has a large, square head with differently sized eyes, with the larger one having a rectangular pupil instead of a round one, and a set of crooked, underbite teeth which are visible at all times. Her short brown hair curls up on the right side of her head. Her breasts point to the sides, possibly another result of her unique genetics. Her usual outfit consists of a white t-shirt with a pink and yellow flower on the front, a pink and yellow-striped skirt, pink socks and black shoes with pink laces.
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 happened, which turned out to be right as he accidentally crushed Gene Kelly with a pillar. She was disgusted with Gandhi and Abe kissing, but soon moved past it, as she invited Gandhi up on stage to dance. She has also laughed at the idea of a 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 prom, she tried to ask Gandhi to go with her, but because of Gandhi acting like JFK, she rejected him, later calling him an ass. Surprisingly, she and Gandhi end up together in a platonic love relationship because they were still young for something serious. She was with everyone else that got frozen in the meat locker, standing next to Gandhi after discovering JFK and Joan of Arc in bed.
Marie is very sweet, helpful and active in school. She is shown to be a talented dancer, impressing the likes of Gene Kelly during dance practice. Marie has a crush on Gandhi, and the two end up getting into a relationship at prom, though only after Gandhi's attempts at flirting with other girls had failed and he realized Marie was the only girl who seemed to actually care about him.
- The reason for her disfigurement was due to her clone mother, the original Marie Curie having died due to disease caused by her frequent exposure to radiation during her career.
