Darth Vader's armor

Darth Vader's armor - Wookieepedia, the Star Wars Wiki:

"Darth Vader's armor was a mobile life support system that Anakin Skywalker was forced to wear to compensate for the serious injuries he suffered after his duel with Obi-Wan Kenobi on Mustafar in 19 BBY. It was designed to maintain and protect the young ex-Jedi's charred body while exuding an air of intimidation and control. His suit followed an ancient Sith tradition, in which the warriors of the dark side of the Force would adorn themselves in heavy armor. The suit was constructed using various methods of Sith Alchemy which served to augment Vader's severely diminished physical strength and vitality."
