[Star Wars] Does Darth Vader poop?
gpt
Well, he doesn't really eat. His life support suit feeds nutrients directly into his body. So his nutrient intake is pretty much 99.99% efficient, leading to a very small amount of waste. He has a pressurized colostomy canister where his solid waste is deposited in. 

Also, you see all those mouse droids? They pretty much fetch his shit whenever his poop canister is full, and then they bring him a fresh one.
