The Serpent's Den

He gets watered once a week.

IV? Maybe he doesn't need food, though, on account of being mostly a machine.

I was wondering that about Bane.

Hm...I imagine he probably ate while in hyperbaric chambers (like the one we have seen in Episode V) since I am pretty sure there is not anything necessary wrong with his digestive system really.

 

*looks it up*

 

Yeah, I appeared to be kind of corrected according to Star Wars wiki. But here is exactly what they said on the matter:

 

"Vader could take food through his mouth, but only when he was inside a hyperbaric chamber, since he had to remove his triangular respiratory vent. It was therefore easier for Vader to receive nourishment through liquids, intravenous and otherwise, and to rely on catheters, collection pouches, and recyclers to deal with liquid and solid waste. Though liquids were preferable, he still had the capacity to chew if he wished, though a nutrient feed provided Vader with all the nourishment he required. In public, Vader was known to claim that he never ate or drank."
