Hmm, for me, maybe Lord Darcia from Wolf's Rain? He treads the line so carefully for most of it, it's hard to tell his true intentions, plus he looks badass, and kinda cute.
Ultimecia from FFVIII was another good one; you never know about her till the end and she controls everything, plus her plan nearly comes through. Plus her final battle is quite hard >.<
