A doppelgänger is a shape-shifter capable of assuming the appearance of another person. Unlike other shifters, doppelgängers often use their transformations to deceive or replace individuals, creating confusion or fear. These beings are often seen as omens of death or misfortune, as their ability to mirror others can cause chaos in social or personal situations.In folklore, doppelgängers are feared for their deceptive powers, often associated with evil spirits or cursed beings.
