The mythology of creatures in Heroes (Goblins and Co.).

I don't have anything against their mythology! I'm just saying that they made a terrible design, but that's just my opinion, although not only mine.

You're right about accuracy, but for the most part, if a minotaur is a human with a bull's head, then it has a bull's head everywhere; if it's a centaur, then it's a human with a horse's torso; if it's a vampire, then it's an undead creature that drinks blood.
