Prob be far to medi-evil for a Pred, but i'd love to see something based around the Ninja Kusari-Gama. The Sicle on a chain, with a big metal ball at the other end. Maybe one hell of a blade at one end and the other end attached to a gauntlet? Making it retrievable and maybe leading to a scenario in which the protagonist of a movie could gain the upper hand on a pred, making the pred fire it into some machinery gears and get pulled in etc. Of course, it couldn't be any ordinary chain, it's gotta be sumthing that in some way could cut through wood, like a hot knife through butter (purely for a scene where the pred would throw it, wrapped around someone and eviscerate them in an instant). Or am i just a sick puppy?
