Walter C. Dornez

Walter C. Dornez, also known as the Angel of Death, is a neutral personality in the manga, Hellsing, and it's subsequent anime appearance, Hellsing: Ultimate. Initially introduced as the butler and ally of the Hellsing Organization, Walter is more than he seems, as he has a history with Alucard, the representation of Dracula in the anime series. He switches sides with the Millennium Organization, and becomes the faction's new secret weapon. The twisted version of the character briefly appears in the final events of the Non-Disney Villains Tournament.
