Goblin
The dark mirror of sprites, goblins are the surviving super-action figures of wealthy boys. Their exterior bodies are composed of, quite literally, slips and snails and puppy-dog tails, and perhaps whatever other bits of the dog they were able to procure.
Goblins are prone to mischief like their feminine cousins, but they lack the same aversion to violence. They've replaced their original plastic rocket launchers and realistic laser-action rifles with small but crippling projectiles of jagged scrap metal and razor wire.
A single goblin may terrorize a small community or household, ruling over it like a spoiled and petulant child. If several form a mob, they will generally undertake some series of grand adventures, seeking treasure and slaying monsters. Unfortunately nearby villages and farms tend to be the objects of their raids, the monsters which present themselves tend to be livestock or wayward travelers.
