Castlevania is an American adult animated streaming television series on Netflix produced by Frederator Studios. Based on the Japanese video game series of the same name by Konami, the first two seasons adapt the 1989 entry Castlevania III: Dracula's Curse and follow Trevor Belmont, Alucard and Sypha Belnades as they defend the nation of Wallachia from Dracula and his minions. The second and third seasons borrow characters and elements from the 2005 entry Castlevania: Curse of Darkness.
