Yoda

Master Yoda is a wise diminutively-sized green alien creature in the Star Wars universe, appearing as a supporting protagonist in the second and third original films, as well as one of the major protagonists of all three prequel trilogy films.

Description
A renowned Jedi master whose dialogue often includes reversed grammar, Yoda made his first on-screen appearance in Star Wars Episode V: The Empire Strikes Back, where he is responsible for training Luke Skywalker in the ways of the Jedi. His final chronological appearance is Star Wars Episode VI: Return of the Jedi, when he floats away peacefully at the age of 900, but not before he reveals to Luke that Princess Leia is his sister. He also appears extensively in the two animated Clone Wars series as well as the Star Wars Expanded Universe of novels and comic books. Despite his old age, he has matched up well against younger opponents.

In the original films, he trains Luke Skywalker to fight against the evil Galactic Empire. In the prequel films, he serves as Grand Master of the Jedi Council and as a general in The Clone Wars.

In 2008, Yoda was selected by Empire magazine as the 25th greatest movie character of all time. On their list of the 100 Greatest Fictional Characters, Fandomania.com ranked Yoda at number 60.

The Phantom Menace
Yoda was Grand Master of the Jedi Council at the time Qui-Gon Jinn reported that he encountered a Sith on Tatooine and he also brought Anakin Skywalker to the Council because he wanted to train him as a Jedi. Yoda tried but he refused, saying there was too much fear in his future. He later attended the funeral of Qui-Gon, who died at the hands of the Sith Darth Maul at the hanger's refinery complex chamber after Obi-Wan was seperated from the duel due to one of the laser gate shields that leads to the chamber. He talks with Mace Windu about the return of the Sith, with Yoda saying that there are always a Sith master and a Sith apprentice. Mace agrees but wonders which one Maul was.

Attack of the Clones
Ten years after Qui-Gon's death, Yoda is still head of the Jedi council and he and the Jedi are dealing with a separatist movement led by Jedi turned Sith Count Dooku. Former Queen of Naboo Padmé Amidala has been the victim of many assassination attempts and the Council sens Jedi master Obi-Wan Kenobi and his padawan Anakin Skywalker to guard her. After a failed assassination attempt by Zam Wessel, Yoda and the Council send Obi-Wan to track down the killer of Wessel and sends Anakin to protect Senator Amidala on Naboo. Later on, he was with the Council when Obi-Wan contacted them from the planet Kamino, where he found that a dead Jedi had a Clone Army made and their genetic template was a man named Jango Fett, who lived there with his son Boba. They tell him to arrest Jango. When Anakin kills the entire Tuskan Raider who killed his mother, he felts it and explains it to Mace Windu. They are later contacted by Obi-Wan, who had landed on Geonosis and found that Jango was associated with Count Dooku and Viceroy Nute Gunray was behind of the assasination attempts on Senator Amidala, but he was captured before he could finish. Anakin got the message and asked if he could go to rescue him, but he was denied by Yoda and Mace Windu. Windu led a strike team of Jedi to rescue Obi-Wan while Yoda went to pick up the Clone Army.

At Geonosis, all Jedi (including Anakin and Padmè, who disobeyed their orders) are surrounded by droids when Yoda and the Clone Army arrive in gunships, saving the Jedi and Senator. Later, after Dooku defeats Obi-Wan and Anakin in a hangar but Yoda arrives and Dooku begins to shoot Force lightning at him, but he is able to reflect it back at him and the two began to duel. Yoda nearly wins, but Dooku causes a barrier to fall on Obi-Wan and Anakin, prompting Yoda to hold it up with the Force, allowing Dooku to escape. The Clone Army becomes soldiers for the Republic and Yoda becomes a general in the Clone Wars.

Revenge of the Sith
Yoda remained Grand Master of the Jedi Council for the three years that the Clone Wars waged. The Council has become suspicious of Supreme Chancellor Palpatine, who was captive on board General Grievous' ship. Obi-Wan and Anakin are sent to rescue him and returne after Anakin kills Dooku at Palpatine's urging. Palpatine then asks Anakin to be his representative on the Council. Anakin asks if he could be a Jedi master, but they deny it and ask Anakin to spy on Palpatine. They send Obi-Wan to Utapau to apprehend Grievous and Yoda travels to Kashyyyk to assist the Wookiees in the war.

After Order 66 is initiated by Palpatine, Yoda felt a disturbance in the Force as two Clone Troopers sneaked up behind him and prepared to shoot him when he jumped up and decapitated them--he and Chewbacca travel into the forests and Yoda remains in a ship so he could go meet Senator Bail Organa. They go to rescue Obi-Wan, who killed Grievous but was betrayed by his soldiers. Yoda and Obi-Wan enter the Jedi Temple where they find out that Anakin had turned to the Dark Side and become Palpatine's (now known as Darth Sidious) apprentice, Darth Vader. Obi-Wan askd if he could face Sidious so he wouldn't have to kill Anakin, but Yoda says that he would be no match for him and goes to confront Sidious.

Yoda arrives at Sidious' throne room and knocks his guards out. Sidious zaps him with Force lightning, but Yoda gets up quickly and the two begin to duel. They fight in the Senate room. The fight ends in a stalemate and Yoda, realizing that he was over-matched, flees into the vents and crawls through them. He leaves with Bail and they travel to Mustafar to pick up Obi-Wan. They arrive and find Obi-Wan (who had supposedly killed Anakin) and Padmè (who was pregnant with Anakin's child) and tak them off the planet. Padmè gives birth to twin who she names Luke and Leia just before dying. Yoda says that they would have to hide the twins from the Empire, so Obi-Wan takes Luke to his uncle and aunt on Tatooine and would watch over him from afar, while Bail and his wife take Leia to Alderaan. Yoda goes into exile on the swamp planet Dagobah.

The Empire Strikes Back
Twenty two years later, Yoda is the only Jedi left as Obi-Wan Kenobi was killed three years ago by Darth Vader. Obi-Wan was training Anakin's son Luke Skywalker, but never told him that Darth Vader was his father. Luke travels to Dagobah after the ghost of Obi-Wan visits him on Hoth, telling him to seek out Yoda to train him. When Luke arrives, Yoda pretends to be a small creature who knows Yoda and offers to take him to him. Later on, while they are in Yoda's hut, Luke snaps, saying that they were wasting time. Yoda begins to talk to Obi-Wan through the Force, saying that Luke was impatient, causing Luke to deduce him as Yoda. Luke convinces Yoda to train him, but Luke got frustrated when he asked him to move his sunken ship and furiously asked him to try. Yoda was able to do it and said there is no try, you do or you do not. Later on Luke had a vision of his friends in pain and went to rescue them abandoning his training, to Yoda and Obi-Wan's disapproval. When Luke left Yoda and Obi-Wan talked with Obi-Wan saying he is their only hope, but Yoda said there is another. (Referring to Leia).

Return of the Jedi
By the time of Return of the Jedi, Yoda had become gravely ill and Luke had returned to Dagobah while in his last moments. On his death bed, he told Luke that his Jedi training was nearly complete with only one last thing remaining: to confront Darth Vader. Unfortunately, after learning that Vader was his father, Luke didn't have the heart to kill him. As Yoda slowly began to lose the will to live, he gave him one last warning about the Dark Side and not to underestimate the powers of the Emperor, otherwise he would suffer the same fate as his father did. In his last words, he tried to tell Luke that there was another Skywalker (referring to Leia being his twin sister) before dying quietly and becoming one with the force.

Yoda is last seen in spirit at the end of the film alongside the spirits of Obi-Wan Kenobi and the reformed Anakin Skywalker, watching the Rebels celebrate their victory over the Empire. He was 900 years old when he passed away.

Star Wars Rebels
Even though Yoda doesn't make a physical appearance in the Disney XD series Star Wars Rebels, he does make a vocal appearance in the episode "Path of the Jedi" where he, through the force, guides Kanan's padawan Ezra Bridger through the Jedi Temple on Lothal.

Disney INFINITY 3.0
Yoda is set to appear in Disney INFINITY's third installment as a playable character.
