Generic Doomsday Villain/Playing With

Basic Trope: A villain without coherent motivation, goals and plans, defined solely by the threat he poses.
 * Straight: General Dusk is a villain that just destroys things and is all-powerful, and nothing else.
 * Exaggerated: General Dusk does random villain things for no reason whatsoever
 * Justified: General Dusk is a practically mindless robot/force of nature/other, so it doesn't really have a personality.
 * Inverted: Ineffectual Sympathetic Villain.
 * Subverted: General Dusk actually has some complexity to him...
 * Double Subverted: Then it turns out to be just an excuse to do whatever he wants.
 * Parodied:
 * The characters point out how one-note and completely unremarkable he is.
 * General Dusk is the Big Bad, yet every other villain working for him has a fully developed personality and ambitions. The joke is from Seargent Night's inability to have any relationship with his master.
 * Deconstructed: ???
 * Reconstructed: ???
 * Zig Zagged: His complexity varies between episodes.
 * Averted: He's actually a very complex villain.
 * Enforced:
 * The writers are lazy.
 * The writers are portraying the villain as a force of nature instead of an individual.
 * Lampshaded: "Okay, why are you doing what you're doing General Dusk? Seriously, you must have some motive!"
