Luke Valentine

Luke Valentine (ルーク・ヴァレンタイン, Rūku Varentain), with his brother Jan, was 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. Alucard then quips that in life (as a vampire), Luke was useless and pathetic. After calling Alucard a "dog of the church of England", Alucard yells "SILENCE", and now, if Alucard is "a dog" as Luke claims, then he is simply "dog food." Luke is then devoured by Alucard's hell-hound.

Luke would later reappear from the hell-hound's corpse with only his upper body free. Confused with this situation, he is quickly killed again by Walter's strings and his and half of Baskerville's body is forced to attack Alucard. This manages to push Alucard for awhile but he eventually shoots Luke and stops the attack. As Walter goes to stab an severely injured Alucard in the heart, it is revealed to be Luke's body acting as a double. This allows Alucard (in his Girlycard form) to sneak up on him. Alucard then remarks at how surprised he is at how useful Luke was, saying "it turns out dog food will do in a pinch".

Abilities
The Valentine Brothers were made specifically to eliminate Hellsing, with Luke being created with the purpose of defeating Alucard. As such he was able to hold an advantage against Alucard until the latter used release restraint level one, at which point Luke was easily overwhelmed.

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), skilled in using his dagger in combat, slicing his opponents into pieces, sharpshooting skills like Alucard, 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 too pleased with the conversation. Luke seems somewhat short with Jan, usually telling him to shut up when he starts rambling.

Trivia

 * Despite having a severed arm during his final [OVA II] moments, it is worth noting that he could regenerate inside Baskerville (with the exception of his legs).
 * In 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).
 * It is interesting to note that the nationalities of the brothers is never made clear, although it seems they are from the United States, judging by their dialogue in the manga, which is devoid of British phrases such as "wanker" (which at least Jan would've used at some point), or German pronunciations (like "ve" instead of "we"), or, if they were thought to be British, the fact that they aren't at all phased that one of Millennium's plans is to wipe out London in what can be thought of as a terrorist attack.
 * Despite the fact that in the manga, only Jan's hat is present in the Valentine brothers' shrine, in the 10th OVA, Luke's curved knife is now his shrine.
 * Luke may or may not have inspired the design of JoJo's Bizarre Adventure Part 7: Steel Ball Run antagonist, Funny Valentine. Their hair and overall appearance are strikingly similar, and their surnames are the same.
