For a large project, i got the "possessed" pending, basically a class-making tool for representing someone who gets power from something that wants control (demonic blood, inner darkness, evil ancestor's spirit, the Hulk or what-have-you). But since the powers and terms of use (so to speak) vary between sources, a single class won't do.
