Contrary to popular belief Darth Vader is really a fairly pitiful villain. When he was young he went by his true name, Annikan Skywalker, and was basically just a pain-in-the-ass crybaby who
never really did much besides win a pod race and
beat a weak apprentice (Darth Tyranus). He was later defeated by Obi Wan and became a pitiful excuse for a human being. After being rebuilt into a
badass looking cyborg who pwned some underlings with the choke(
the one truly great thing he did) he was beaten by his son. Basically, he seems like an amazing villain, but if you look close he is nothing much, he just has a great image.
cool things:outfit, breathing, force choke, sounds awesome, wipes out some sand
people in rage, force choke(it simply has to be said again, it is truly amazing)
crappy things:beaten by Luke(who was whiney and un-cool), beaten terribly and utterly by Tyranus in Episode II, was second in command to a non-force user on the
ship he was on in Episode IV, whines ALL the time and cries as teen Annikan, loses to Obi Wan(and loses most of his limbs),
never even becomes a master
