After losing his father’s lightsaber on Cloud City, Luke Skywalker constructed a replacement with a green plasma blade, its hilt similar to that of Obi-Wan Kenobi’s weapon. Luke hid his lightsaber inside R2-D2’s dome during his mission to rescue Han Solo from Jabba the Hutt, and surrendered the weapon to Darth Vader as part of his effort to reawaken the spirit of Anakin Skywalker.
