DarthxVader
what force ability could the Emperor use that Darth Vader couldn't why couldn't he use it and what was the ONE time he was able to use it
BTW, if you're going to try to correct someone else, it helps to be correct in the first place.
First off, there's lightning, which is a dark side skill, and arguably capable of being said "one time to be used" if you go by the definition that that which is in teh movies is the only time it was 'seen' and thereby 'used'. Then there's sith alchemy, which Palpatine used in his clone bodies. Then there's of course the force storm that consumed the eclipse.... And The list goes on.
