The character of Marie Mjolnir like many other characters in Soul Eater is based on classic movie monsters. She is obsessed with getting married, which is a cue to the Bride of Frankenstein, and also explains her infatuation with Frank N. Stein. She has the power to turn into a hammer, which explains her last name, Mjolnir, which was the name of Thor's hammer in Norse Mythology. This could explain the lightning bolt on her eyepatch, although that could also be a reference to the Bride of Frankenstein once again, who had a lightning bolt shaped streak through her hair. Her first name is most likely a reference to Marie Shelly, the author of the Frankenstein novel.
