A ghoul, if it is the result of a transfusion of vampiric blood, will have the bitemarks of the vampire who has injected said blood into their viens. Coming from these bitemarks are long and tribal-esque markings that wrap around the neck and face. After transformation, the victim's eyes become pupiless and gain new dark rings under them.
Ghouls have the red tint in their hair that vampires have, but slightly darker. Even their eyebrows become more pointed and sharp. Of course, ghouls sprout fangs after transformation, as they are of vampiric descent.
Powers & Abilities: A ghoul has the strength and endurance of a vampire, but don't have the common sense or thinking ability to use them responsibly. This results in everything looking like an enemy to them, even allies. It has been shown that after transformation, the ghoul has no memory of its true self, with the exception of the strong-willed. But even with a strong concience, the ghoul is only forced to watch what they have done, thus deepening their torture.
They possess a strong bloodlust and since they hold no concience to hold them back, ghouls go on a killing spree as soon as they are released.
