I'd love a villain who is Dangerously Genre Savvy and really forces the heroes into desperate situations. Maybe even stick in a Sadistic Choice here or there for good measure. Perfect example of such a villain: Spoiler (Move your mouse to the spoiler area to reveal the content) Show Spoiler Hide Spoiler Ozymandias in Watchmen: “Dan, I'm not a Republic serial villain. Do you seriously think I'd explain my master-stroke if there remained the slightest chance of you affecting its outcome? I did it thirty-five minutes ago.” A good Well-Intentioned Extremist or Knight Templar character (with better characterization than say, Count Dooku) would probably be my first choice for a villain, but really, any type in the spectrum of Lawful, Neutral, or Chaotic Evil works so long as the villain has a compelling backstory and/or motivation.
