Peter F.Hamilton :
Difficult one to choose. SF has produced some greats over the years. If I could narrow it down to three, in no particular order.
1. The Tanu in Julian May's Saga of Exiles - beautiful and deadly, unhampered by anything approaching our morals they hold a dark fascination for so many humans they ensnare.
2. The Hood in Thunderbirds - sorry, but he scared me crapless when I was a boy.
3. Alien / Alien Queen - Oh come on, you knew that was going to be on the list.


Terry Bisson :
Cardinal Brownpony in Miller's Saint Leibowitz and the Wild Horse Woman. The best (worst) bad guys are the ones who think they are doing good.
