Jason Voorhees is the villain of the Friday the 13th movie franchise.
Voorhees is a unique horror villain because, in a lot of ways, he is completely unimpressive. He's sort of bumbling and clumsy, a little bit overweight and generally pretty slow.
When he catches his victims and does his thing, I find myself wondering, "How are people actually allowing themselves to be done in by this oafish figure?"
Mike Russow embodies the same general sentiment when he fights.
In his past two UFC bouts, Russow has looked mediocre at best, seeming slow and like his punches had nothing behind them. However, he won his last two fights, and they were both finishes.
When Russow steps in the cage and fights, you think there's no way he'll win and then he pulls off the victory, much the same way as it seems like Jason shouldn't be able to catch anyone, but always does.
