Doppelganger

The Doppelganger is a recurrent boss in the Mega Sonic Bros: The Soul of Dracula series. It is a demon that takes the form of another being, usually its victims. The idea of humans having doppelgängers comes from Egyptian mythology. It is said that if someone ever meets their doppelgänger, its intent is to murder them so it can take over their role in life.
