Re: The Most Heinous Star Trek Villain
My first pick would have been Kivas Fajo -- am I going to cause angst by asking "why no Kivas Fajo"? His is a much more personal, intimate heinousness and in some ways more creepy and effective because of that; he's no world-destroying super-baddie, just a greedy, petty, pretentious sociopath, and he's all the more memorable for that.
Saul Rubinek was awesome in that role.
Self-appointed Knight of the Abrams Table! - Thanks Marsden!
