Having existed in legend and folklore for so long, vampires have been perceived in a variety of ways over the centuries. Since the 18th century, vampires have primarily been depicted as malevolent humanoid beings that seek power and control over mortal men, enthralling innocents by draining their blood and making them susceptible to their commands. While vampires normally appear human, they have elongated fangs for puncturing the necks of their victims, draining the blood from there. Some vampires develop feral, animalistic expressions when caught in battle or while they are feeding
Because vampires are undead, they have no true life force of their own, hence why they are forced to feed on living blood. The reasoning behind their blood dependency varies between their different iterations; some vampire types with origins more grounded in the realm of science feed on the blood of others because their own blood cannot sustain haemoglobin whereas the more classical types of vampire feed on blood due to being cursed or simply because they are villainous beings who delight in killing and dominating others
