Attributes: The alien is the abberant, the anomalous, the deviant aspect of humanity, that just does not fit. Over the years, he came in any of a myriad manifestations, but all of them have the single trait in common of being unable to fit in with anything. Even others like him. He represents all that is shunned and different from that which is normal. The Alien is an abomination and only exists to balance perfection with imperfection.
symbols: The Duck-Billed Platypus, The Leper, The Vampire, are all symbolic of that which is unnatural, and deviant from the normal.
Suspected Avatars in History: John Marrick (The Elephant Man) is one. Anyone who has been persecuted for being different.
51%-70%: Rejection is prevalent in a dense aura surrounding you, and any time you are contained in one area for too long, you may make an Avatar: Alien check to be effectively ejected from it in whatever way reality dictates.
71%-90%: If you make a Soul check against someone else's Mind Stat, you can instill a deep fear and loathing of themselves for their predjudice. Failure will result in a fear and loathing of you. It cannot be said how the victim of this will be affected, but the GM should think of something appropriate, like a level seven Self check.
91%+: Nobody or anything can keep you. Any successful Avatar: ALien roll you make can allow escape from anything. Or instill a fear of you so great that nothing can cause them to take ANY action towards you, good or bad. Your death will prevent this however, as that is the one thing that NO ONE can escape from.
