Frankie Stein is a 2010-introduced and all-around character. She is a simulacrum, specifically the daughter of Frankenstein's monster and his bride, and a student at Monster High. In retro-spec, she is a Frankenstein's monster, as Victor Frankenstein had built her or Frankenstein's monster himself, but in the books, she is built by Viktor and Viveka Stein and she is their daughter in the book series.
