Seriously. Was there a pressurized room or something? Did he ever eat or did he just live on IV fluids?
There was a pressurized chamber where he could do his business. EDIT: I think a more mysterious question is whether Vader still had 'junk' after the whole Mustafar thing-a-majig.
http://en.wikipedia.org/wiki/Colostomy http://en.wikipedia.org/wiki/Urostomy I would say his sex life was somewhat non-existent post-Mustafar, however. "NOOOOOO!!!!!" means no. Palpatine probably punished Vader by getting Mara Jade to give him lap dances.
According to Dark Lord: The Rise of Darth Vader: "He could take food through his mouth, as well, but only when he was inside a hyperbaric chamber, since he had to remove the triangular respiratory vent that was the mask's prominent feature. So it was easier to receive nourishment through liquids, intravenous and otherwise, and to rely on catheters, collection pouches and recyclers to deal with the liquid and solid waste." So there's an EU explanation. As to what the films say on this matter, I don't think it's likely that Anakin would have his "junk" still intact considering the severity of his burns. If we look at this image, for example, the skin on his left thigh has been completely burned away and while other areas, such as his groin and part of the abdomen, are still covered by clothing, it's very likely that this material would have melted and adhered to his skin, causing significant damage anyway. At the very least, due to the extreme heat, he's going to be infertile.
they're aliens who says they need to go to the bathroom at all? perhaps all the food they eat is used so they don't need to have leftover waste to excerete
Huh? I've never read any of Zahn's books so I'm not really familiar with what you're referring to, unfortunately.
I choose to believe he did because most of my fangirlish fantasies depend on it. Also because the benevolent government that was the Empire must have offered great health coverage to its valued employees.
You fantasize about burnt up amputated mass murdering cyborg, Darth Vader? I was in my teens embarrassed about my fantasies about Leia in the gold bikini.. That's seems pretty normal now VS Seriously?
His DFR timeline has Darth Vader running around years before Luke's conception. Which I take to mean the junk in the suit must still work...
