If 0-0-0 wasn’t a true show of just how evil the Dark side could be, I don’t know what is.
As if being tortured by a droid with a limitless knowledge of ways to inflict pain wasn’t enough, imagine being tortured by a droid that looks and acts like C-3PO.
0-0-0, who was on loan to Vader via comic character Doctor Aphra, was well-versed in commerce, communication, and various forms of torture.
Anyway with his new red eyes, 3PO is looking suspiciously like 0-0-0.
