Yoda is a fictional character in the Star Wars universe, first appearing in the 1980 film The Empire Strikes Back. He is a small, green humanoid alien who is powerful with the Force and is a leading member of the Jedi Order until its near annihilation. In The Empire Strikes Back, Yoda was voiced and puppeteered by Frank Oz, who reprised the role in Return of the Jedi, the prequel trilogy, and the sequel trilogy. Outside of the films, the character has been mainly voiced by Tom Kane, starting with the 2003 Clone Wars animated television series. Yoda is an iconic figure in popular culture due to his distinct pattern of speech and role as a wise mentor. In his first appearance in the original trilogy, Yoda is described as the mentor of Obi-Wan Kenobi, and lives in exile on the swamp planet of Dagobah. He trains Luke Skywalker in the ways of the Force until his death at the age of 900 in Return of the Jedi, though he later returns as a Force spirit.
