Vampire

"Vampires are still mysterious to us. The stuff of legend, we know them to be creatures of the night, devours of living blood, who walk the plane between our world of the living and the shadowy world of death. Throughout our history, some among our species have attempted to romanticize them; turning them into handsome womanizers and cunning seductresses. The truth of the matter is that our species is woefully ignorant. Our ancestors knew the truth but were so terrified by it, they eradicated all but scant mentions of them from the histories. The truth about vampires... the real ones... is an ancient secret, dating to a time that predates man. And with it is a fear you will take with you for the rest of your days..."

- Human lore concerning Vampires

Vampires (ヴァンパイア Vanpaia), known by a myriad of other names, many among them being Walking Dead (僵屍 Kyonshi lit. Reanimated Corpse), Nightwalker (夜策 Yoru Sansaku), Crimson Plague (紅疫病 Beniekibyō), are a supernatural species of the undead that feast on the blood of the living. Traditionally depicted as reanimated corpses who rise to drink the blood of the living, vampires are in fact a form of the undead that were all formerly human; the only possible exception being Alucard. Vampires solely drink the blood of humans, and can be considered their natural predator.

Regarded as creatures of myth, vampires are some of the most feared creatures in human folklore, and as was the case with the disappearance of the years ago, many humans no longer believe in the existence of these dangerous creatures.

Conversion
A vampire bite can be equated to poison; once bitten, a human is transformed into a vampire within a time period of 72 hours. The transformation itself is not painful; the toxins themselves dull the nerves and keep the victim calm and sedated, though still very much aware of their surroundings.

A bite is not entirely incurable; within a 48 hour period, the transformation can be halted through a special antidote, designed by reverse-engineering the vampire venom itself. Alucard is noted to keep a regular supply of this on hand for dealing with particularly stubborn humans who require the threat of "conversion" to bend them to her ways. Beyond this point, however, the transformation enters its final stages and can no longer be prevented.

Nutrition
Vampires, as would be expected, feast on the blood of humans, and are unable to digest solid food anymore. Additionally, only the blood of humans is compatible with the vampire's digestive system; animal blood or demon blood can be ingested, but has no nutritional value to the vampire body at all. Solid food, however, is shown to be rejected by the vampire's body, causing them to vomit it up in the same way a human's body would purge itself of poisonous or diseased material that has been consumed. The more blood a vampire consumes, the stronger they become; thousands of years of feeding on the blood of the living stockpiles a vampire's strength, contributing to their magical energies and granting them immense magical power.

While a vampire's body requires human blood to function properly, much like a human would require food, Alucard has developed a liquid she refers to as Stigma (スチグマ (代替血) Sutiguma; lit. Alternate Blood), which was created to mimic human blood and be compatible with a vampire's body. Regrettably, this failed, however, the liquid itself can sate a vampire's hunger for a period of time, enabling them to go about interactions with humans with no need to consume their blood. As with all substitutes, the real thing is eventually craved and required, and a vampire will eventually hunt again as Stigma temporarily loses effectiveness.

Physical Attributes
Vampires, due to their status as undead entities, have biology that differs from humans, changing the internal workings of their bodies as soon as the transformation is completed. Many of the changes done to the body tie into their status as the undead, however, others contribute to the vampires existence as a whole. Quite similarly to a Slayer, a vampire's lungs and stomach are much more durable than a normal humans, and they can breathe in or ingest toxins with little to no harm to themselves, though this appears to vary with the amount taken in.

Vampires no longer possess a beating heart, however, blood still flows strong within their veins; it is implied the strong magical energies of a vampire carry the blood throughout the body, and it works identical to human blood. These same magical energies are what tie the vampire body together, and enable them to perform powerful regeneration. While a vampire has to breathe, as their blood still requires oxygen as much as a human does, they are able to hold their breath for much longer than a normal human, around a full hour at any given time. This would imply that the transformation from human to vampire increases the amount of myoglobin in the body tissue, allowing for a vampire's body to hold oxygen far longer than that of a human. True to the statement, the flesh of a vampire of much darker than a human, bordering on black instead of the normal red. The flesh of a vampire also takes three decades to fully be digested when eaten.

Vampire skin is also known to be highly susceptible to sunlight; prolonged exposure to the sun will cause the vampire to combust. A vampire who is particularly long-lived, when nearing a millennia of life, adapt, and id themselves of this weakness, only feeling mild discomfort in sunlight. Notably, silver is the primary weakness of a vampire; silver is a metal that holds unique Eterano within it that reacts to a vampire's own powerful magical energies; the very same that keeps their body functioning properly.

A unique trait about vampire's is their own scent; quite possibly to aid in hunting humans, vampires have a scent that is noted to be particularly alluring to humans. Alucard herself notes this to be a superfluous trait as vampires are more than capable of handling a normal human.

Due to silver's properties as a very effective conductor of heat and electricity, the eternano within the silver creates a powerful reaction when touched by a vampire in particularly large amounts, the eterano enables the silver to absorb the heat and bioelectric potential from the vampire, (the ability for nerve endings to actually give commands), and therefore disabling them if struck with a high enough concentration and/or quantity. The effect only takes place with a considerable quality of silver, as a vampire can hold small silver items without critical damage to their body, and it is only temporary and can be removed if the silver itself is removed from the body of the vampire.

Regeneration & Biological Immortality
Vampires are very difficult to successfully kill. Due to being undead, a vampire cannot die in the natural way; they do not die of old age, and are unable to succumb to diseases and the like. Even assaulting a vampire's body in an attempt to slay them will often prove fruitless, as vampires possess a very strong regenerative factor; they can even regenerate from being vivisected, or having a fist-sized hole blasted into their torso. There is a limit, however, to the remarkable regeneration of a vampire. The vampire body is linked together by their magical energies; if their limbs are severed, they can restore them by simply reattaching them. However, for a complete regeneration, the severed body part no longer has to be "alive". As such, if a limb was severed from the body, but kept safe, hidden away, it would never regenerate; the vampire in question would have to find the limb themselves and reattach it. If the head was severed, a vampire can survive this and reattach it, however, if it was to be taken and locked away in a safe underwater, they would remain conscious and alive, but unable to regenerate the head as their body would never decay.

It also takes 30 years for a creature to digest the flesh of a vampire; if a vampire's arm or leg was eaten by a large creature such as a dragon, unless the vampire victim personally retrieves it, the limb will not regenerate until it's been completely digested. The only way to ensure a vampire dies when they are killed is to completely destroy the body; they are unable to regenerate without an 'anchor' so to speak.
