Doppelganger

Doppelgangers are beings from the Mirror World, a realm similar to ours but inverted. In the Mirror World, the evil within people takes on a life all its own, personifying itself into an evil twin of everyone who lives in our world. Dimensional travelers or magick-users have been known to open, either intentionally or inadvertently, bridges between our world and Mirror World.
Doppelgangers appear as darker, edgier versions of yourself. They are the personification of your personal evil so whatever sins or temptations you've been through the most will determine much of how they act. Oh, and they will know everything about you, because they are literally your dark side. 
Doppelgangers are normally capable of anything you are, unless your powers are fueled by Kenosis. Even then they can generally produce imperfect imitations. Killing a Doppelganger is easy, or at least its as easy as it would be killing yourself, since technically they are you, sort of. 
== Mirror World: ==
Mirror World was created slowly and over time by the collective sinfulness of humanity. In Mirror World, all your personal evil, even the mere temptations you have felt, are personified into a sentient being who is forever linked to you. To kill your Doppelganger is to kill a part of yourself, or at least a part of your history.
