This is the introduction of the next chapter in vampirilistic venture: The TWK Vampire.
The original name actually means Tweaked or Tweak Vampires, meaning changed or altered. These are a set of vampires all together different from the original damned blood suckers.
Anatomically speaking, these vampires are extremely different from your original vampires. The TWK has all the same perks as a normal vampire, with increased strength, speed, agility, and intelligence. But the TWK don't have to worry about sunlight, though they do have a slight allergic reaction to pure UV. They don't have to worry about crosses or churches, but they also have allergic reactions to silver and garlic.
In with the differences of there being hood, TWK also have souls, they only need to worry about reproducing to keep the species alive. A matriarch would appear to have been the cause of them, his body much more perfect to life then the majority TWK vampires.
TWK Vampires also have altered insides of there bodies, the appendix changed into an organ that can withdraw, then excrete into the body pure energy from the blood drank from others, a new circulatory system for this drank blood instead of having to eat. The blood is then perspired as water vapor and various other gases, the blood vaporized in the appendix.
As a last comment toward the TWK, they also posses some sort of ability, chosen at random as much as to the color of your hair, you get powers such as controlling lightening or fire, energy diversion ect. ect.
In conclusion, the TWK is really only the next step into evolution from a human, there lives extended far beyond that of a human, there minds like cameras with the kind of memory they have, they gain intelligence by the seconds. Nature is attempting perfection with the skin and hair, never aging, living near forever.
