The only reason he was able to put up a fight was because he was a cyborg with the ability to spin his limbs 360 degrees - thumbdown
No Force abilities - thumbdown
Didn't make his own lightsaber, just stole them - thumbdown
He was SO STUPID that he didn't put more protection around his organs, just two metal plates that opened like doors - thumbdown
He was BUTT UGLY - paperbag3
ZOMG HE HAD FOUR ARMZ!!!!!1
...and?
he sucked. all he was, was a gimmick. he was a marketing gimmick, and even pertaining to the plot he was a gimmick. he had no force capability, rendering him unable to take on a jedi in a one on one lightsaber battle. thats why he needed 4 arms: gimmick. the theory was that seeing four swiveling lightsabers would make a jedi freeze like a deer in headlights. and it may have worked for a while until kenobi proved what a punk b!tch he really was. grievous, in fact, gets the coveted 'punk b!tch of the entire saga' award, surpassing boba fett, kit fisto, and even jarjar binks. GO GRIEVOUS!!!
