His inner demons are legion,and when he's pushed far enough Zappa summons up the evilest and most vile demon of them all. Don't make him angry! You won't like him when he's angry! Zappa searches for Faust to relieve him of his terrible affliction.

Report #6940
Name: Zappa
A mental parasite known as the "vengeful spirit" has not yet been fully studied, but there are numerous examples. As an existence their true self is unknown, but there are theories that they are the left-behind wishes of the dead, or even a secret weapons project from the Holy War or before.
The subject is host to a particularly suspicious mental parasite and several have been known to attack to him. If he can be captured, these can be studied, and perhaps work can begin on a mental-physical weapon.
The subject's movements are erratic because of the vengeful spirits, so prediction is difficult. With all this in consideration, we assign a Risk Rating of B+.
