- "Now, I know how it feels to be Padmé."

Darth Vader's penis was Darth Vader's penis, Duh. It was frequently a victim of the Force choke, although rarely in public. After the fall of the Jedi Order, it featured quite prominently in the Rise of the Sith. It is used in a similar fashion to the lightsaber, holstered at the hip, although most of its abilities can be negated with a cold shower. Power levels have been shown to rise in the presence of specific materials.
Darth Vader soon lost his penis though, in his fight with his old "mentor" on Mustafar. When the Jedi Master defeated Lord Vader, he proclaimed his love for him, after this Obi-Wan collected Vader's lightsaber, his rectum, and his penis.
Luke Skywalker found his fathers missing body parts years later in Obi-Wan Kenobi's bed, Both were frozen in carbonite, Wormie puked very hard and we don't blame him. Only one testicle was included in the carbonite slab, and that ultimately proved the truth in the old raucous Rebel song "Vader has only got one ball".
His penis was never replaced with a functioning robot dick and is now a series of tubes allowing him to pee. In it's place is now a pez dispenser.
