The characters are inspired by monster movies, sci-fi horror, thriller fiction and various other creatures.

The original Monster High dolls were created by Garrett Sander, with illustrations by Kellee Riley and illustrator Glen Hanson. As of July 12, 2018, 189 web series episodes were produced and released – including the reboot series. The web series finished its first run in 2015 with Volume 6, and got rebooted with a long-form 11-minute, 12-episode series order titled the Adventures of the Ghoul Squad.

Along with its feature-length direct-to-video films, this series serves as a platform to launch new doll characters. The series follows a group of teenage children of famous monsters in media and film as they attend high school. Monster High is an animated web series based on the eponymous then-freshman American fashion doll line created by Mattel, the first adaptation since its launch, which originally aired on YouTube from May 5, 2010, to February 9, 2018.
