Alucard

Hellsing Organization, his master is Sir Integra.

As he is essentially immortal and invulnerable, Alucard is very egotistical. He freely taunts and belittles his opponents, often allowing them to inflict seemingly fatal wounds before healing himself and counterattacking. One of his favorite methods of fighting is to allow himself to be blown to shreds before simply flowing back together. Underneath his arrogance, Alucard is deeply sad and appears to be envious of humans. Alucard also has great respect for humans who have the willpower to endure old age and death because he had none of these qualities when he faced death. To add onto that, he is also slightly vulgar and makes some crude jokes even if he doesn’t really mean it.

After consuming Schrödinger accidentally and being lost within himself for 30 years, Alucard emerges with the Werekin's powers. He is both nowhere and everywhere. As people saw that Schrödinger couldn’t die when shot in the head, the reason behind this is due to people thinking of his existence and that he is able to escape death. The Major has stated that Schrödinger only exists for as long as he is aware of himself, however, Alucard didn't recognize himself during the events of the Battle of London, therefore, he disappeared and was gone for 30 years. Alucard, after he's back at the Hellsing Manor, explained that during the long 30 years, all he's been doing is killing all the souls inside of him when he absorbed the millions of people that died in London, except for one soul; Schrödinger's. So as long as Alucard is fully aware of his existence, he would be alive and can use Schrödinger's powers freely, however, if he does not recognize himself, he will disappear from reality itself and become "Nowhere". It is apparent that Alucard has this ability because he is able to appear within the Hellsing mansion as nothing but a shadow, not alarming Seras' familiar, shadow Pip, who covers the entire mansion.

Black messy long hair, pale skin of a vampire, fangs, He appears as a tall, long-limbed, broad-shouldered adult man of indeterminate but reasonably young age, as is commonly seen among vampires. Alucard possesses blood red eyes, which may glow when he is experiencing strong emotions. Though as stated above, he can change his hair as it's a part of his shadow. He commonly has long, jet-black hair and his bangs fall slightly in his eyes, with strands on the sides of his bangs framing his face in this form. He is above 6ft. His usual outfit is comprised mainly in a classic Victorian fashion. It includes a charcoal suit, leather riding boots, and an intricately knotted red cravat, covered by a full-length, red frock overcoat (similar to the duster coats often associated with cowboys) with cape. He also wears a wide, floppy brimmed red fedora and a pair of circular, heavily tinted, wire-framed orange sunglasses with goggle sidings. His gloves, which are engraved with the Hellsing seal (a pentacle decorated with occult symbols and several mottoes, reading: "Hell's Gate Arrested / Gott Mit Uns / And Shine Heaven Now") are also thought to be part of this mechanism and the source of Hellsing's control over him. (Alucard's distinctive gloves are visible in the vast majority of his transformations, even when Alucard himself is not in a humanoid form.)

500+ years, he’s a vampire. He was born in 1431.

Unknown but he does show some interest for Seras Victoria.
