i'll have to break this down by genders:
fav male hero: Trevor - having to live with people afraid of you builds character, i'm of sure.
fav female hero: Give me some more Sonja Belmont. I don't care how you do it. If there's something in the story you don't like, just take out that one part, don't throw away the character with it. My theory still is that all the males in the Belmont Clan were wiped out by Dracula's forces, so she then became the true heir to the Vampire Killer whip and had the right to keep the Belmont name.
fav male villain: I'd have to say Olrox right now. on this board, a few pages of him were translated from a novel. he paralyzed a fearless vampire hunter by having in his employ humans, who simply shot the hero without him ever killed a human before. there's a gentlemanly quality to him, and he's a wild card. i'd like to know more. he gained control over Graham's cult and challenged the forces of chaos. oh, an Brauner got to wear his suit in Harmony of Despair. wonder if there is a connection between them in the iga-canon.
fav female villain: i think there needs to be more Actrise. that hair and hat =) such dastardly deads.
