Real name: Vincent van Dam

Alucard was once known as Count Dracula, also known as Vlad III Dracula, the son of Vlad II Dracul. Born in 1431, he later became known as Vlad Ţepeş ("Vlad the Impaler") and as Kazıklı Voyvoda ("the Impaling Voivode") by the Turks, gaining a fearsome reputation throughout the lands. He is arguably the first vampire that ever existed.

He was enslaved by Ottoman conquerors when he was a child (make an exchange of Noble Children was often used for maintain peace between Turk and Christian Kingdoms) and molested/raped by a high ruler. During the whole ordeal, he defiantly clenched a silver cross. When he became the Voivode of Wallachia, he launched an all-out war on the Turks which devastated both sides. Eventually, his troops were defeated, his people were killed (many by his own hands), and his homeland was set ablaze. Vlad himself was to be executed. However, before he was beheaded, he drank of the blood from the battlefield and became a true vampire. When he accepted the powers of darkness, the silver cross he had always carried with him shattered.
Centuries later, in 1897, Abraham Van Helsing, Arthur Holmwood, Quincey Morris, and Jack Seward were able to defeat Count Dracula and killed those who served him. He was given a new name, Alucard, by Arthur Hellsing. In 1944, Alucard, along with a 14-year-old Walter C. Dornez, is sent on a mission to Warsaw, Poland, to stop Millennium's vampire production program. They presumably destroyed the project, but its main architects escaped. Decades later, in 1969, Alucard was imprisoned in a dungeon in Hellsing manor by Arthur. According to Sir Hugh Irons, Arthur Hellsing came to believe that Alucard was "too powerful a drug to be used as more than the occasional medicine".
