Darth Vader

I dont think we see Vader with a double bladed lightsaber, Vaders style of fighting is to crude of a style to use a dobble bladed saber a style that demands high mobility . Crude because of his mechanical limbs

I agree.

Is the 'force-choke' something Vader developed or do all siths have that power?

I would believe every sith can do it

So can Vader use force lightning as well? Or is that a secret known only to the sith master (Palpatine in this case) and not imparted to the apprentice?

think it would burn his gloves 😉
and dooku knows it, so it isn't master-only

Forgot about him. And doesn't Vader have artificial hands anyway? Maybe that would prevent him from using the dark side of the force to do something like that.

one articial hand yes, not sure about the other one
but you can do lightning with one and two hands

when he absorbed han's blaster shot in to his hand, was it his artificial hand, or real?

it was his right, so it was artificial
the shots of the blaster never full hit his hand for the glove to get any damage

So Vader has one mechanical arm and one real one? Or at least that is our understanding right now. Does he have any other mechanical body parts we know about?

his breathing machine

in an interview with GL about the prequels and the OT he said Vader is pretty injured, breathing machine,mechanical arms!! and probably legs too

I have no doubts that both his arms are of course, but up till now, only one is mechanical

as Anakin yes

I figured as Vader he was messed up real bad. So the loss of his right arm is just the beginning.

Guess good ol Anakin have loads of ouch times ahead of him

A little bit of trivia, did you guys know that David Prowse didnt know that his voice would not be used until the movie was completed. He found out when he saw the finished movied that his voice was out and James Earl Jones was in???? He was pissed!

I read that in a Starlog magazine last year sometime.

Yeah that would suck pretty bad.
