The conversation between human and AI assistant.
What did they do to Darth Vader's costume in Rogue One to make him look even more evil than previous films?
What other changes have they made to Darth Vader's appearance over the years?
Well, in the original trilogy, his costume was more streamlined and sleek, whereas in the prequels they added more intricate details and designs to his armor. Overall, though, his appearance has remained fairly consistent throughout the Star Wars saga.
