Yoda is the oldest Jedi Master from Star Wars. His Lightsaber crystal is green.
Notes[]
When Qui-Gon Jin died, Yoda takes his place as Obi-Wan's master. When Anakin Skywalker's hand gets sliced off by Count Duku's lightsaber, Yoda takes Anakin's place in the battle. Yoda is one of the few Jedi not to be killed by Anakin Skywalker in episode III. He later dies and appears as a ghost.
