Pretty is a cutie, isn't he? Too bad HE CANNOT BE TRUSTED! He ain't no cell, he ain't no normal protein, he ain't no virus, and he ain't no bacteria either! He is a PRION, one of the most brutal things in Cytology! He is the guy - or better yet, protein - behind the so-called mad cow disease and IFF... You really want to stay away from him!

Normal proteins are friendly helpful and totally sane, Pretty, on the other side, is a real narcissist! Raised normally to only suffer later on his half-life, he decided to turn into a prion, and now, he is only waiting for the right time... The right time to DEGRADE EVERYTHING!
