I'd like to mention The Major from Hellsing he truly was a great villain. 1.Evilness- The Major was a sadistic, insane Na zi Major who waited for more than 50 years to fight another battle partly because he wanted to defeat Alucard, but also because he loved War. 2.Accomplishments- The Major spent more than 50 years planning to return and wage the final battle of WWII. He successfully waged war against the Vatican, Hellsing, Britain, and the USA. He also managed to get rid of Alucard, the most powerful Vampire, for 30 years. 3. He's notable amon Anime fans.
