Vampires

The vampires of this universe are different than the ones you're so familiar with. These people are infected with a virus from a bite (if there's enough blood left for them to survive on), and over time, while exhibiting flu-like symptoms, their bodies change drastically. Their eyes become opaque, they grow claws, their bones shift - where they end up isn't always helpful - all of their organs except their brains, hearts, lungs, and stomachs disintegrate, and their veins and arteries form new connections to the stomach. They feed on blood not to satisfy their hunger, but because they need blood flowing through their veins. The blood that they recieve is absorbed by their bodies after a few weeks, prompting the necessity for feeding. While they are quite deformed in their natural states, they can take on their original human state - they just are not able to recieve as much blood and are more susceptible to injury.

Strengths and Weaknesses

 * Can go weeks without feeding with a sufficient amount of blood
 * Heightened senses and agility
 * Can climb walls with ease
 * Have sharp claws in both their natural and human forms which can rip through anything with ease except metals
 * Usually have abnormally high temperatures due to their increased blood flow; this does not affect them negatively.
 * If injured, they bleed out fast unless the wound can be sealed tightly, otherwise they will lose all their collected blood through just that one wound
 * If they don't feed, they will be stuck in their natural form until they become so animalistic that they will kill and feed on the first animal or human they see
 * Immune to all disease, but if the human they fed on was carrying a blood disease, they will suffer from that disease until the blood is fully absorbed
 * Can be killed as easily as humans in addition to dying from sunlight exposure (although it takes about an hour)
 * Do not live forever, although they live longer than humans (they crumble into dust anywhere from 170 to 200 years of age) and do not visibly age
