12 Ruthless Movie Villains Who Lost To Complete Fools

12. Biff Tannen

The Hero: Marty & George McFly

For multiple generations the Tannens were the scurge of Hill Valley: from schoolyard bullies to gun-toting outlaws and megalomaniac overlords, they held the town in a vice like grip of fear, ruling from their various seats of power with impunity.

They were villains, good and proper. So why exactly were every single one of the villainous Tannens featured in the Back To The Future series undone by a hyperactive, backwards-running social misfit with a penchant for making rash decisions and a questionable relationship with an elderly eccentric?

Marty could never have physically bested Biff, and yet he did so on multiple occasions, and even worse, he was knocked clean out by a single punch from a sci-fi writing, socially-awkward dweeb with a peeping tom problem in the shape of George McFly. In reality, this would have all went differently.
