A system used to classify Anti Villains and their likelihood to morph into classical Villains. Type I: A restrained villain, who has a set of standards that they would not cross. Alternatively, villainy is just a job for them.
Type II: A woobie villain, who does not want to be evil, but circumstances make them out to be. Tends to garner sympathy.
Type III: A well-intentioned villain, who may believe in good goals, but use whatever means they can to achieve them.
Type IV: A villain in name only, lacking any genuinely villainous traits, or simply called a villain for opposing the protagonist. Frequently overlaps with Hero Antagonist.
