In the Akumajo Dracula X CD liner notes, the game's character designer Toshiharu Furukawa stated that they had to remove some monsters in previous Castlevania games, due to the game's international localizations. Having destructible monsters with humanoid forms (i.e. Medusa, Carmilla, and Gargoyle) went against America's morals. However, for Castlevania: Rondo of Blood, it doesn't need to be localized, due to it being released in Japan-only.
