3. General Grievous
Four lightsabers? Four? Upon first viewing of Grievous fairly early in
Star Wars III: Revenge Of The Sith, it's hard not to be intrigued. This is a droid with something of a personality, wears a cloak and uses Jedi weapons. It's certainly different. Unfortunately, the interest stops there when it comes to this wheezing bore, who, despite looking fairly badass, spends much of the movie running away after talking himself up. When he finally steps into a fight with Obi-Wan Kenobi, the Jedi Master defeats him with a blast to the chest where some sort of organ dwells, and watches the droid burn up and die. Also, what is he wheezing for? He has no lungs.
