After-Evil

An After-Evil is a manifestation of a powerful villain after they are killed. The After-Evil is part of their soul and it has some of their memories, it has their darkest feelings of anger and hatred. They can only be visible in the real world unless they are inhabiting a body. When they are born, they are cosmic energy instead of having a physical form. It may be possible that the phenomenon of ghosts is really After-Evil beings trying to communicate with the living world.
