Luke Valentine

Luke Valentine, with his brother Jan, is a vampire and minor antagonist in the beginning of the Hellsing series. His Seiyū is Takehito Koyasu while he is voiced by Patrick Seitz in the English Dub.

Appearance
Luke has pale skin, long blonde hair tied with a white ribbon at the end, and green eyes. He wears silver pince-nez glasses and the same style of military jacket as his brother Jan, although Luke's is white with gold lining. In the manga, his jacket is black with white lining. He also wears white suit pants, white gloves, a white suit jacket over his jacket; in the OVA, a white overcoat draped over his shoulders is added. He later loses this overcoat during the Valentine brothers' invasion of Hellsing headquarters.

History
Luke likes to fancy himself as the one who will bring about Alucard's demise, believing that because of his relatively advanced powers that he was destined to surpass Alucard in every way. He believes that he has more than Alucard's powers at his own disposal, and believes Alucard to be just another artificial vampire like himself. He soon finds that this is far from the truth, being soundly beaten by Alucard, who pleads with Luke to call upon more powerful vampiric abilities (having already been impressed by Luke's speed and reflexes) but is disappointed to find Luke can't even heal his severed legs. After calling Alucard a "monster", and saying he is nothing more than a "dog" of the church, Luke is devoured by Alucard's hellhound. Alucard quips that in life (as a vampire), Luke was useless and pathetic, and now (if Alucard is a dog) he is simply "dog food." Later during Alucard's final battle with Walter, Alucard summons Luke as a familiar. Walter uses his wires to sever Alucard's arms and legs, to cut his torso in half, and to suspend him helplessly in the air. He then grabs a metal bar and attacks Alucard, impaling him through the chest. The Alucard that Walter attacked, however, was a decoy, created by Alucard using Luke's remains, allowing him to shapeshift and sneak up behind Walter. Luke is now believed to be dead for good.

Abilities
While Jan, save for some over-the-top strength and agility, is a more basic vampire, Luke in particular demonstrates an extreme form of celerity (more evident in the OVA II) and accelerated healing, recovering quickly from being pierced by the soldiers trap spears and regenerating from being shot in the head by Alucard in the OVA and in the chest in the manga. His regeneration is not unlimited, for when Alucard shot him with the Jackal (which was made for use against regenerators like Alexander Anderson), he could not regenerate his legs.

Alucard
''Note: The information posted is only from the Hellsing OVA. More information from the Hellsing anime and the Hellsing Manga is needed.''

When Luke meets Alucard in the sub-levels, Luke seems to be quite condescending to Alucard in the beginning, but frightened towards the end where Alucard kills him. Luke claims that he will prove that immortality is a myth, once he has Alucard's head on a stick in the Hellsing OVA II. After Alucard tore off Luke's legs, Luke refers to Alucard as the dog of the Church of England, to which Alucard replies by calling Luke 'dog food", followed by devouring him as Baskerville. Alucard goes back to that comment while belittling what is left of Luke. "As a vampire you were just a pathetic piece of shit. Now you're nothing but dog shit."

Jan Valentine
Given how short their time on-screen together was, it's hard to say exactly how well the two got along. Obviously, Jan is very comfortable talking with Luke, chatting the entire way to the Hellsing Mansion. Luke, however, didn't seem to pleased with the conversation. Luke seems somewhat short with Jan, usually telling him to shut up when he starts rambling.

Trivia

 * In the Japanese Manga and OVA II, Alucard remarks near the end of their battle that he considers Luke "above even a Class A vampire"; in the anime, however, he simply saw him as a "Class A Vampire".
 * It is worth noting that Luke Valentine is the only member of the Millennium Group to be killed by Alucard exactly the same way in every incarnation of the series (manga, Gonzo series and OVAs).
 * The 9th Volume and OVA reveal that Luke, unlike his brother, holds a military rank within Millennium, namely Warrant Officer (the same as Schrodinger).
 * On the contrary with Rip van Winkle and Tubalcain Alhambra, the other vampires devoured by Alucard, Luke seems to be remained the person he was even after his death by Baskerville, Alucard's hellhound. This turns out as he gets out of Baskerville (the hellhound was killed by Dark Walter). As the Doctor and Alucard explain it, Luke just had had an indirect connection to the No-Life King, which was broken by the hellhound's death, and he would have probably lost his characteristics after being diggested by Baskerville. However, when he charges against Alucard as Walter's puppet (but probably by his own will as well), Alucard respects him for this decision, even if he called him a "piece of shit" before.
