Give us memorable villains!

So, you're saying that an end villain named "Kobold Grunt" wouldn't make for a satisfying game experience? Jeepers, y'all are needy!

I think that even if the main villain is a plumber named "Welton Laramie," if the story builds him up into a larger-than-life master of the diabolical and gives the player a great game experience finding him and defeating him, he could still be a "memorable" one.

Compare the visually malevolent villains such as Darth Vader, the Borg and Sauron (both the LotR and the Captain Power versions) to the ones that were built up, like Hamlet's King Claudius, Kaiser Soze and Hannibal Lecter. Are any in the second list any more or less memorable than those in the first, even though there's nothing in their appearance that would scream "BAD GUY"?
