Mattel's fashion doll franchise Monster High features a variety of fictional characters, many of whom are students at the titular high school. The female characters are classified as Ghouls and the male characters are classified as Mansters. The characters are generally the sons and daughters, or related to monsters that have been popularized in fiction. The franchise's official website identifies six of the characters as Original Ghouls. In addition to the listed Ghouls and Mansters, there are other characters who have been introduced in the franchise's related media including the web/video and book series. In 2016, singer Lady Gaga's sister Natali designed Zomby Gaga for the Monster High franchise as a partnership with the Born This Way Foundation.
