Alucard is the most powerful warrior of the Hellsing organization (and, arguably, the world). He is not only a vampire, but also one of the most ancient ones. He usually dresses up in a Victorian fashion, including a gaudy charcoal suit, leather riding boots, and a flamboyant and intricately knotted red bowtie, covered by a long red trench coat. He also wears a red fedora hat with a wide, floppy brim and a pair of circular, heavily tinted, wire-framed yellow sunglasses. He has an unbelievably vast range of supernatural powers and is an expert gunfighter, his enhanced strength allowing him to wield pistols that most would consider heavy weaponry.

He fights with ferocity and often extreme cruelty, rarely shooting to kill until his target has been totally disabled and humiliated. He has a massive ego, and frequently gives enemies more than one chance to kill him before retaliating, just to demonstrate his enormous powers.
