Short description: A spontaneous betrayal of morals due to a convenient temptation.

Long description: Like a villainess with a Freudian Excuse, this type is corrupted by outside forces. Unlike one with a Freudian Excuse, however, this does not occur through tragedy, but rather, opportunity. This villainess may start out on the ethical side of the story, and for all intents and purposes, would have likely stayed there, if not for an intervention of fate which awakens a dormant, but otherwise, intense greed (or other unsavory desire).
