Villain Sue

""Every first novel is the author either as Jesus or as Faust.""

- Unknown, possibly Oscar Wilde.

Mary Sue is hardly limited to always being a goody two-shoes. This brand of Mary Sue decided to take the dark and evil path, kicking a few dogs and probably cackling about it in the process. Whether it be stealing the Cosmic Keystones out of the grasp of the heroes, effortlessly bringing about the ironic utopia of the other villain, or just generally acting like a cad, they absolutely love to be evil.

But anyway, this character pretty much shows up as an author's wish fulfillment to just be evil. Alternatively, in Fan Fiction, it might show up because the author favors the villain and wants a vicarious relationship with them. It might be a consequence of Evil Is Cool, taken to the logical extreme. Or, perhaps, the author just has a distaste for some (or all) of the protagonists and created the character to facilitate a Hate Fic, Fix Fic, or Revenge Fic. Either way, the same author favoritism and plot bias are now working for the forces of evil. It may also come about as an attempt to create a Magnificent Bastard or similar style of villain, only to go too far and become one of these.

As far as overlaps go, there are two major ones. Sympathetic Sue is an easy one where the intent is to show that the character just had a crappy enough life to be forced into villainy. With this overlap, they are more of a Villain Protagonist than an antagonist in most cases. Tends to show up most often in fanfiction. The other common overlap is the God Mode Sue, with a ridiculous power level, forcing the heroes to hold the Idiot Ball, and/or requiring Deus Ex Machina in order for the protagonists to stand a chance of defeating them. This is the type that generally shows up in Canon. It can overlap with other types, such as Jerk Sue, as well, but it never overlaps with Purity Sue (although they might become one after the Heel Face Turn, once the plot forgets everything evil about them).

Probably the rarest type of Sue, as Villains are always given great powers and abilities to make their inevitable downfall more sweet. A true Villain Sue will probably never have one, however, and even if he does it may be via Only the Author Can Save Them Now rather than any non-Ass Pull method.

Compare with Magnificent Bastard, God Mode Sue, and Generic Doomsday Villain.
