Vampire

The vampires in the Twilight series have certain distinctive characteristics that set them apart from other fictional vampires, some of which include appearance and hunting styles.

Appearance
Vampires are normally extremely beautiful, this is for attracting their prey, humans. Their skin is extremely pale. Also described as extremely cold, as hard as granite and is often compared to alabaster. They bore resemblance to statues because of their stillness and granite hard skin. Their scent is very appealing to humans who get close enough to smell them. Vampire eyes start out as a crimson red; a red eye color indicates that a vampire is either a newborn or has recently consumed human blood. The color becomes onyx black when a vampire is in need of blood. However when a vampire's eyes are a golden color, it indicates that a vampire has instead consumed animal blood. Their irises fade in color as time passes after their feedings. Purplish-black bruises appear under their eyes, becoming more pronounced with thirst. The bruises signify the fact that vampires never sleep. They are extremely pale, but flush slightly after feeding. Their skin also sparkles like diamonds once exposed to the sun, giving them the reason to never show themselves in public when the sun is out and uncovered by clouds. They do not need to breathe, however they generally do out of habit and because they feel uncomfortable without their sense of smell. They are also unable to sleep, age, or grow. Their voice also becomes more alluring through the transformation, allowing them to bring in or attract their prey/humans.

Eyes
A vampire's eye color changes with their diet, whether they drink human or animal blood. Hence, the Cullens all share "liquid topaz" eyes. The Cullens have all fed on animal blood for so long, that their eyes have become this golden color. Bella first notices Edward's eyes in Twilight, saying that "His eyes were black, coal black." This was because as a vampire gets thirstier, their eyes grow darker. Edward was so thirsty at the time, his eyes had gone as dark as they could: black. In contrast, as a vampire drinks more blood, their eyes become lighter. Only the Cullens (Olympic Coven) and The Denali Coven are the known "vegetarian" vampires.

If a vampire was to have a diet that consisted entirely of human blood, their eyes would be a vivid red, like that of James and Victoria. Like the vegetarian vampires, their eyes grow to a more vivid red as they feed on human blood, and a darker, more burgundy color as they abstain from human blood. Meyer writes that, "If a Cullen were to drink human blood, his/her eyes would turn burgundy. If two weeks pass without human or animal blood the vampire's eyes go entirely black. If that Cullen then returned to an animal diet, his/her eyes would return to dark gold. Brand-newly created vampires are recognizable by their eyes, which are a vivid, bright red due to the massive amount of human blood (the blood that was already in the human at the time he/she was changed) that lingers in the tissues. That red fades slowly over the course of a year.": The eyes are one of the most characteristic things that show the most or stand out.

Gold = Animal blood Red = Human blood or Newborn Black = Thirsty

Speed
Once a human completes the transformation to become a vampire, they acquire certain superhuman abilities; speed is one of these. The speed at which a vampire can move and be fast enough, that the human eye can barely recognize when a vampire decides to move at such high speeds. It is implied that a vampire is meant to move on to different area every so often and the ability of speed seems to push that idea to never stay in one place too long, as it is very easy to run. When Rosalie was beaten to almost death by Royce, Carlisle picked her up and took her to his place to transform her, she described the journey as being like 'flying'. It is not just physical movement that can be exceptionally fast. Speech too can be faster than the human ear can make out. The speed can help the vampires chase animals (like the Cullens) and/or other vampires (like Victoria and James).

Edward's speed can be inferred from chapter 13 of Twilight. He circled the "small meadow" in half a second. He was lying beside Bella, twenty feet away from the border of the meadow. Assuming they were positioned in the center of a 20 feet radius round meadow, his speed was 171 mph (276 kph) to cover it in half a second. When Edward carried Bella back to the truck, assuming his speed decreased to 2/3 the normal speed due to the extra load and safety concerns, he would cover the 5 mile distance back to the truck in 2 minutes and 40 seconds. This is compatible with Bella's description in chapter 13: "in a matter of minutes, we were back to the truck."

Strength
The ability to use superhuman strength is one of the characteristics that set vampires apart. Edward’s physical strength is seen in stark contrast to the fragility of human Bella. A vampire’s diet does not have a massive impact on the levels of strength, in fact hunger or intimidation can increase strength much like a human when in danger. "Human blood does make them stronger than animal blood, but only fractionally. Big game (bears, wildcats, predators) makes them stronger than the "weaker" blood of herd animals." Ultimately, physical strength is always going to come down to the individual vampire, rather than secondary factors like their diet. However in the case of newborn vampires, the large amount of human blood in their system vastly increases their strength. Bella says that someone so small like Alice would have the strength to cripple a car easily. Edward told Bella that when she became a vampire, she would be able to beat Emmett Cullen in an arm-wrestling match. As Emmett is the strongest Cullen, Bella was very surprised to hear this news. Strength, of course, is not always physical. It is impossible for a vampire to die through physical starvation, but a lack of blood intake does alter a vampire's mental state.

Physiology
As a person is changed into a vampire, their physical appearance is enhanced, their eye color changes, their hearing and eyesight becomes more acute, their heart ceases to beat, and they no longer need to breathe, sleep or blink. Natural changes in the human body do not occur any longer, mainly because the venom replaces all of the natural chemicals processes and functions in the body. As the vampires describe themselves they are like stone, frozen exactly like they were when they were transformed. That is the reason why male vampires have sperm but females can't have children. Males require no change whatsoever to produce sperm, but females must physically change to bear children, so only males can have children but only with human females. Other things, such as fingernails and hair, also cease to grow. It is worth noting that, to a human, a vampire’s body is comparable to granite or marble (though to another vampire the skin feels very smooth and soft); this a reflection of how vampires are essentially unchanging, like "living stone." Vampires can be killed, but it is almost impossible to accomplish, as they are nearly indestructible. The only way to kill a vampire for good is to rip apart the body and burn the pieces. Werewolves and shape-shifters are very capable of killing a vampire, as the two are at a slight advantage over them as long as their combat techniques are up to match. Vampires themselves are the most likely to succeed in killing their own species, as they are equal to their target in physique and mentality (at least this is most likely), unless the target has a special ability or "gifts."

Of special note is a vampire's body chemistry, as described in Breaking Dawn's FAQ section on Stephenie Meyer's website. Although vampire skin serves the same basic purpose of human skin to protect the body, the transformation process makes their cells hard and reflective, like crystal. As such, a lubricating fluid that is chemically similar to their venom is produced in order to make movement possible for the vampire. A similar fluid also coats their eyes so they can move easily in their sockets (though actual tears cannot be produced because tears are meant to protect human eyes from damage, which is, obviously, unnecessary for a vampire's eyes); in this same pattern, a variety of venom-based fluids exist to perpetuate bodily functions similar to those that existed when the vampire was still human - even many functions that blood serves in humans are carried on in some form in this manner. (It should be noted that these fluids can't transform humans into vampires the way the actual venom can.) One particularly important effect of this is the presence of a fluid related closely enough to human seminal fluids that it can bond with a human ovum, which is how it is possible for human-vampire hybrids such as Renesmee and Nahuel to be born. Another important consequence is the fact that the venom-based lubricant (and, therefore, probably the rest of the fluid types as well) is very flammable, explaining why setting vampires on fire is so effective. It is likely that the necessity of ripping the vampire's body to pieces before incinerating them is to prevent them from putting out the fire themselves before it can do serious damage.

Transformation
Transformation from human to vampire is described in Twilight as being "...the sharpest memory they have of their human life." A human is bitten, and venom from glands inside the vampire's mouth is injected into the bloodstream. Depending upon "how much venom is in the bloodstream, and how close the venom is until it enters the heart", the transformation could be anywhere from 3–5 days, but it is interesting to note that if directly injected into the heart then it could only take 2 days. During that time, the human will endure indescribable pain," The warmth inside my heart got more and more real, warmer and warmer. Hotter. The heat was so real it was hard to believe I was imagining it. Hotter. Uncomfortable now. Too hot. Much, much too hot" as described by Bella Cullen as the venom slowly circulates through the blood and eventually reaches the heart. Once the venom is injected, it is described as being "...the beginning of the greatest pain you will ever understand. The venom then has to make its way all through the body. Next through the heart, and it will pump again and again in the heart until it starts meeting itself in the veins. Then it will burn all the veins until the heart stops beating. It moves slower than blood because it’s thicker. Each beat of the heart can only push it so far. The changing/burning process is slow. The venom has to saturate every cell in the body before it ends.

Abilities
All vampires are described as having superhuman strength, speed, durability, stamina, agility, reflexes, and regeneration. Their senses are incredibly keen, and the range/power of their tracking senses is greatly enhanced. For example: they have excellent vision, able to smell blood, hear heartbeats from miles away, and hear others speaking from a great distance. They are able to move, jump, climb, and run incredibly fast; running is described as a second nature to vampires. One of their most significant abilities is their immortality which makes them immune to the effects of aging as well as to all diseases and viruses. If the vampire coven remain in one place for too long (like the Volturi) then after a few thousand years they may take on the appearance of fragility, as Bella describes Marcus, Caius, and Aro's skin to be like "paper," but they are not fragile. Similarly, the Romanian coven's skin appears slightly petrified, which Vladimir and Stefan explain is due to the fact that they remained still for a very long time. Vampires will live forever unless they are dismembered, which they could live through, as body parts can still move and reattach themselves, but to permanently kill them you then have to burn the pieces. It could be speculated that burning alone would kill a vampire without dismemberment, since the limbs do not seem to lose their resilience when seperated from the body. In all likelyhood, the reason for dismemberment is so that the vampire is unable to move out of the fire. The possibility exists that Alec could use his power to numb a victim, so that they would not know they were burning, and would not act to prevent their destruction. Vampires also have photographic memories, and thus greater learning potential than a normal human.

Special Talents/Abilities
A small number of vampires gain special talents from when they are changed into their new form. If they had a characteristic or personality that was very dominant in their human life (such as charisma or sensitivity), it would be possible for it to be magnified into a power or talent after their "change". Some talents mentioned are mind reading, second sight, the ability to change others' emotions, cripple people with their mind and distinctive feels for other vampires' gifts.

Deviations from traditional vampire legend
Vampires in the Twilight world are different from most other literary vampires. One fact is that they have very few weaknesses - they are not harmed by holy water, the sun, garlic, or crosses. They are also unhindered by running water as traditional vampires seem to be. Vampires in Twilight are not burned by the sun, but rather their skin sparkles like diamonds in sunlight. Additionally, they have a reflection in mirrors, cannot be killed by wooden stakes and will show up in pictures. At the same time, vampires traditionally never had to reproduce and they turned humans through biting. Vampires in the Twilight series are also incapable of sleeping. It is unknown what happens to a vampire after they die.

In physical appearance, vampires in Twilight do not have fangs, as their teeth are incredibly sharp and strong. Vampires in Twilight also do not sleep in coffins. As for the similarities between vampires in Twilight and traditional vampires, they are both gifted with some psychic and supernatural abilities, for example, mind reading. Vampires in Twilight tend to show more of their humane side. They are shown to blend more with humans: for example, the Cullens - despite the fact that they are vampires - still attend school.

Enemies
Vampires in the Twilight world are said to have one natural enemy: werewolves

Vampires also often fight among each other. There have been many cases throughout history where vampires create armies of newborns to challenge each other and gain territory.

The La Push shape-shifters are also meant to protect the Quileute Nation from vampires, making them enemies of vampires as well.

Also, if one vampire attacks/kills another vampire's mate, then the mate of that deceased vampire will likely hunt and plan revenge on the killer of their mate, such as Victoria/James and Edward/Bella.
