The head of a character that has been violently removed from the rest of its body, cutting the brain off from its necessary supply of oxygenated blood. Aside from unusual circumstances (such as being undead, an android, or some other creature with no need of blood) a character injured in this way will always lose consciousness within seconds and quickly die as their brain starves for oxygen. As a result, any "normal" character whose head has been removed is either already dead, or on the very cusp of death.
