Alucard

The secret weapon of the Hellsing organization, Alucard is a vampire specializing in killing other vampires. At first glance, he seems to be nothing but a rather odd gunman, but when he truly unleashes his powers, it becomes quite clear that he is not a mortal. After walking the night for half a millennium, he is constantly seeking a worthy opponent, and with his powers of regeneration, strength, and shape-shifting, not to mention his army of familiars, he lays waste to any of his master's enemies.

However, beneath his cool and heartless exterior lurks a dark and tragic past, and a longing for the only thing an immortal can never have.

Several of the typical weaknesses of vampires have no effect on him, like sunlight, as he claimed in chapter 13: "Sunlight is not my greatest enemy... I just HATE it!" He can also travel over running water without any problem.
