[Star Wars]Why didn't Darth Vader just clone replacement body parts/limbs?
gpt
Cybernetic replacements have many advantages over organic ones. They don't degenerate with age, they're heat and pressure resistant, they're fully customizable, they have low risk of being rejected by the body, and it's very possible to make them into enhanced versions of what the limb used to be. That being said, Vader didn't have much choice in the matter. Although he was awake for the process, it was not by choice. Sidious made sure he was kept awake so that the pain would enrage him. Vader was delirious throughout most of it. By the time he was fully aware again, the procedure had already been finished and Vader had his prosthetics. By doing this, Sidious was able to make sure the prosthetics given to him were heavy and unwieldy, which made it difficult for Vader to ever attempt to overthrow Sidious.
