Castlevania is a long running video game franchise created by Konami. Over its twenty three years the franchise has featured many Monster Girls, from harpies and succubi to Alarune and even a werewolf. One of the most commonly appearing monsters is Medusa, who's made boss appearances in all three introductory Castlevanias as well as most games since. Because of how popular and prolific the series has been over the past decades it could have been the introduction to Monster Girls for many individuals.
