Marilyn

Marilyn is a Hufflepuff girl in the PC game Harry Potter and the Philosopher's Stone who can be found outside the room where Fred and George Weasley give the "wizard card" of Betie Bott to Harry Potter. She appears standing next to a window with a rather vain ("I wonder if there's a spell to make me even more beautiful") Slytherin girl who tells Harry that Marilyn is "a bit off."

Marilyn was slightly shorter than Harry, had blonde hair worn in a ponytail and collected beetle pincers. In the PC game Harry Potter and the Chamber of Secrets, it is revealed she has a younger brother named Arthur.
