No one of them is the least bit scary to me, all of them are too humanoid looking to be scary but then, werewolves, vampires and such aren't scary to me either, nor are arachnids or any insects, snakes, animals etc... Anything natural looking is not scary. Many can be dangerous and, deserve respect but they are nothing to fear. For me to fear it, it would have to be clearly alive, capable of movemnt and attack but, entirely not of this world. Now that would be scary, totally unkown, none of the things that are predicatble about denizens of my world, it might not even think like anything I know, won't act like it and, may be provoked by what I think is avodiance or kindness. Might interpret me not showing fear as a direct attack, etc.. That's scary.
