10. Jabba The Hutt
Oh no, a giant slug! It sounds childish, but for all intensive purposes, that's all big Jabba is. Sure, he's probably pretty devious and he knows a tonne of shady characters, and has loads of bounty hunters at his beck and call, although they're all in Star Wars, so probably can't shoot very accurately. He also owns the Rancor, a monstrous creature that feeds on people in a cave underneath his palace. But surrounding yourselves with threatening things does not necessarily make you a threat, as was proved when Jabba was strangled to death by the least threatening person in the room, Princess Leia in her underwear. He obviously can't move very fast, because he doesn't have any legs and clearly has a huge amount of weight to shift around. He has arms, but they're probably not long enough to scratch his head. They're certainly not stronger than the grip of Leia, who's hardly a weightlifter, and probably hasn't been able to hit the gym on Alderaan in a while...
