Hellsing

Hellsing was originally a manga made by Kouta Hirano for the older, more darker form of the human being. The comic was originally eight volumes long, consisting of bloody, gory vampire action that involved the protaganist, Alucard (in Japanese, it's Arucard because of Engrish and such), a Nosferatu who hunts down those of his own kind, the undead. He meets with a police girl named Seras Victoria, who becomes a secondary protaganist, next to Alucard and is nomally a sex symbol for the kind of manga genre she is in. Alucard is under the control of her master, Integra Wingates Hellsing, who is the leader of the Hellsing Organization, a group of undead hunters who's goal is to cease all earthy activities of those not of the undead classification. Now, there are also secondary characters like Walter, the Hellsing family's butler, and Paladin Alexander Anderson (in Japanese it's Paladin Alexander Andersong), as well as the Nazi organizations that seem to appear quite frequently in this. There are variants of Hellsing, which include OVAs (original video animations) and the anime, which is thirteen episodes long. It is disputed which ones are better, because many fans prefer the manga over the anime. The OVA is the anime-form of the manga exactly, but the anime is not anything like the manga at all. Then were are things like "Hellsing: The Dawn" which feature much younger versions of Alucard and Walter as they fight the Nazis. That's when Walter is nicknamed "The Angel of Death" by Alucard. It is a highly recommended anime by those who like horror and such, but in reality, it's more of a thriller than a horror. There is a lot of swearing as well, as well as blood and death, so it is not recommended for children under the age of thirteen. To learn more, actually reading the manga or watching the anime is also recommended.
