After a ferocious battle with his former master, Obi-Wan Kenobi, Anakin is left for dead beside a lava flow on Mustafar, and is outfitted with an artificial life support system as well as robotic arms and legs.

Obi-Wan Kenobi ( Alec Guinness ) explains that the Galactic Empire had all but exterminated the Jedi some twenty years before the events of the film, and seeks to train Luke Skywalker ( Mark Hamill ) to be the Order's last hope.

In Star Wars Episode I: The Phantom Menace ( 1999 ), Jedi Master Qui-Gon Jinn ( Liam Neeson ) discovers nine year old Anakin Skywalker ( Jake Lloyd ), whom he believes to be the " Chosen One " of Jedi prophecy who is destined to bring balance to the Force ; the boy is eventually paired with Qui-Gon's apprentice, the young Obi-Wan Kenobi ( Ewan McGregor ), who promises to train him.

The sequel, Attack of the Clones, establishes that the Jedi forswear all emotional attachments, including romantic love, which proves problematic when Anakin, now a young adult ( Hayden Christensen ), falls in love with Padmé Amidala ( Natalie Portman ), whom Qui-Gon Jinn and Obi-Wan Kenobi had served ten years before.

Occasionally, performing an extraordinary ( usually heroic ) act can earn a Padawan learner Jedi status, such as when Obi-Wan Kenobi defeats the Sith Lord Darth Maul.

McGregor previously starred as Jedi Knight Obi-Wan Kenobi in the prequel trilogy.

Qui-Gon and his padawan, Obi-Wan Kenobi ( Ewan McGregor ), persuade Jar Jar's tribe to release him to their custody as a guide.

Coincidentally, Lawson is the maternal uncle of Ewan McGregor, who played Obi-Wan Kenobi in the prequel trilogy.

Unknown to Vader, the young senator has hidden the plans inside the Astromech droid R2-D2 and has sent it to find Jedi Master Obi-Wan Kenobi on the nearby planet of Tatooine.

She is finally rescued by Luke Skywalker, Obi-Wan Kenobi, Han Solo, the Wookiee Chewbacca, and the two droids, R2-D2 and C-3PO.

After Padmé dies in childbirth, Jedi Masters Obi-Wan Kenobi and Yoda decide that they must hide the Skywalker children from their father, former Jedi Knight Anakin Skywalker, who has recently turned to the dark side of the Force and become the Sith Lord Darth Vader.

Frustrated, Luke contacts master slicer Ghent, who manages to recover one other holoclip from R2, this time featuring a scene in which Padmé is talking to Obi-Wan Kenobi about Anakin, which is displayed to both Luke and Leia.

Later, it plays as R2-D2 plays her holographic message to Obi-Wan Kenobi.

The theme plays when Obi-Wan Kenobi is killed by Vader.

It appears in Star Wars Episode III: Revenge of the Sith, when Bail Organa has a conversation with Obi-Wan Kenobi about adopting her.

Boba helps the bounty hunter escape from Obi-Wan Kenobi ( Ewan McGregor ), but later witnesses Jango's decapitation by Mace Windu ( Samuel L. Jackson ).

He is introduced in Star Wars Episode IV: A New Hope, in which he is forced to leave home, and finds himself apprenticed to the Jedi master Obi-Wan Kenobi.

When Padmé dies in childbirth, Jedi Masters Yoda and Obi-Wan Kenobi hide the children from their father and Emperor Palpatine, the ruler of the newly-declared Galactic Empire.

He takes his first steps toward his destiny when he finds two droids, C-3PO and R2-D2, the latter of whom is carrying a message for Obi-Wan Kenobi, known to Luke as the hermit old Ben Kenobi.

Later, in Edge of Victory: Rebirth, they have a son whom they name Ben after Obi-Wan Kenobi, who used Ben as a pseudonym.

This was because in Attack of the Clones, Anakin's lightsaber was built to be reminiscent of the lightsaber in the original trilogy, while in Revenge of the Sith, Vader's lightsaber was designed to match the lightsaber that Obi-Wan Kenobi gives to Luke Skywalker, in Star Wars Episode IV: A New Hope.

Michael Kaminski argues in his book that it is unlikely that the plot point had ever seriously been considered or even conceived of before 1978, and that the first film was clearly operating under an alternate storyline where Vader was a separate character from Luke's father ; there is not a single reference to this plot point before 1978 ( further reinforcing this is Obi-Wan Kenobi calling Vader " Darth ", as if it is his true name rather than his new Sith name ).

Obi-Wan Kenobi is a character in the Star Wars universe.

Obi-Wan would then go into exile on Tatooine to keep an eye on Luke during his formative years.

Obi-Wan tells Luke that his father was a Jedi and presents him with his father's lightsaber.

Obi-Wan offers to take Luke to Alderaan and train him in the ways of The Force, but Luke rejects his offer.

During the Rebel Alliance's victory celebrations on Endor, Luke sees the smiling spirits of Obi-Wan, Yoda, and his father, Anakin Skywalker.

After writing the second and third drafts of Empire Strikes Back in which the point was introduced, Lucas reviewed the new backstory he had created: Anakin Skywalker had been Obi-Wan Kenobi's brilliant student and had a child named Luke, but was swayed to the dark side by Emperor Palpatine ( who became a Sith and not simply a politician ).

Obi-Wan Kenobi is first introduced in Star Wars Episode IV: A New Hope ( 1977 ), where he is played by Alec Guinness and is first seen rescuing Luke Skywalker ( Mark Hamill ) from a group of Tusken Raiders.

Obi-Wan Kenobi takes Luke to his hut, where he reveals that he knew Luke's father, Anakin Skywalker, and served with him in the Clone Wars.

Obi-Wan Kenobi offers to instruct Luke in the ways of the Force and asks him to join him on the quest ; but Luke is only persuaded when his aunt and uncle are slain by the Empire, whereupon Obi-Wan Kenobi takes him to deliver the message to Alderaan.

While that is going on, Obi-Wan Kenobi disables the tractor beam so that the Falcon can escape and confronts his old apprentice, Darth Vader, in a lightsaber duel, eventually sacrificing himself so that Luke and the others can escape.

In Star Wars Episode V: The Empire Strikes Back ( 1980 ), set three years after A New Hope, Obi-Wan Kenobi appears as a Force ghost and instructs Luke to visit the Dagobah system for further training under Jedi Master Yoda ( Frank Oz ).

After Luke has been further trained in the teachings of the Jedi, Obi-Wan Kenobi appears in the Dagobah swamp to dissuade him from going to Cloud City, where Vader holds Han Solo and Princess Leia hostage.

In Star Wars Episode VI: Return of the Jedi ( 1983 ), set six months after The Empire Strikes Back ( in the novelization ), Obi-Wan Kenobi appears on Dagobah to talk with Luke, who has learned from a dying Yoda that Vader is indeed his father.

At the end of the film, Obi-Wan Kenobi's ghost appears alongside the ghosts of Yoda and a redeemed Anakin Skywalker on the forest moon of Endor, watching Luke and his comrades as they celebrate the destruction of the second Death Star.

Luke is put on Tatooine with Owen Lars ( Joel Edgerton ), Anakin's stepbrother, and Obi-Wan agrees to look after him in secret ; Luke's twin sister Leia, meanwhile, is adopted by Bail Organa.

He and Obi-Wan obtain passage with the smugglers Han Solo and Chewbacca on their ship, the Millennium Falcon, only to find that Alderaan has been destroyed by the Empire's new superweapon, the Death Star.

Suddenly, R2-D2 plays a message from Princess Leia Organa ( Carrie Fisher ) that pleads for Obi-Wan Kenobi to get the droid to her father on Alderaan.

Obi-Wan survives the attempt on his life and escapes, rendezvousing with Yoda and Senator Bail Organa ( Jimmy Smits ) of Alderaan aboard Organa's ship, the Tantive IV.

Yoda and Obi-Wan Kenobi survive the initial purge and are picked up by Senator Bail Organa of Alderaan aboard his diplomatic cruiser Tantive IV.
