Alls I know is, despite appearing reptilian, I like how much Olrox/Orlox resembles Count Orlok. It's a neat homage and a strange twist on the character, making him so huge and all when his man-like form is broken. It's a shame Castlevania games don't feature more "lesser" vampires (although Orlok would be a serious contender to Dracula, I'd imagine). That's one thing I really like about the N64 games: vampires everywhere! Apparently Vampire Killer MSX has vampires, too.
