Fantasies Are Real Forum Favorite Creature

Hello all, I am just curious, what is your favorite magical creature of all time?  It can be a type of witch, fairy, whatever. Please be specific.

i think vampires are cool (they are not cliche, damnit!) and any kind of half human-half animal is cool. human+cat, human+bird, cat+bird (whoa. i think i like that last one.) you know.

what do you like?
