7. The Leprechaun (Leprechaun Series)
Leprechauns are nice. Evil leprechauns are awesome. This particular evil leprechaun emerged in the first movie when he was trying to locate his missing his bag of gold, which had been lost for ten years. Usually, when you think of leprechauns, all you think about is friendly little Irish fellows who wouldn't hurt a fly and knowing that Warwick Davis is the man behind the villain in these movies shouldn't really do anything to change that view - but he's actually pretty terrifying. The leprechaun was very powerful, able to rip a man's heart out and possessed powers such as teleportation and telekinesis and he was also nigh unkillable apart from when his weaknesses came in to play. Of course, there were several sequels and, in the most recent instalment, Davis was replaced by WWE's Hornswoggle.
