Goblins

Goblins are ugly and malicious creatures that are much like Trolls, but are considered a fantasy species in their own right - often having magical powers and prone to living in creepy, abandoned or menacing places but never too far from populated land as they enjoy tormenting others. They are stock characters in many fairy tales and other fantasy media, also due to their frightening nature they are a common motto for villains who may not actually be goblins themselves, the most iconic of which is the Green Goblin and his many heirs.
