7. Having His Gold Stolen (The Leprechaun)
What tends to spring to mind when you think of leprechauns are friendly little Irish fellows who bring good luck and wouldn't hurt a fly. However, this one was an evil, frankly murderous little bugger and was incredibly powerful. He was strong enough to rip a man's heart out and possessed powers such as teleportation and telekinesis. He was pretty much unkillable - that is until his major weakness came in to play; when he loses his gold, he loses his powers and becomes vulnerable. The Leprechaun is also weak to four-leaved clovers, wrought iron and a very specific and particular magic medallion.
