One of the most innovative, exciting, and tragic things in Star Wars: A New Hope was the duel between Obi-Wan Kenobi and Darth Vader. The duel ended with Obi-Wan's death and the disappearance of his body (we would later find that he had turned into a Force ghost), and Luke had to come to terms that his mentor is gone.
Obi-Wan Kenobi famously distracted Darth Vader and allowed himself to be struck down to give Luke, Leia, Han Solo, Chewbacca, and his two old droid companions time to escape in Star Wars: Episode IV - A New Hope. Obi-Wan became a Force ghost thereafter, with his body disappearing as Vader's lightsaber made contact.
When Obi-Wan died, he joined the cosmic Force. His presence in the living Force wouldn't exist, unless he manifested. So Vader wouldn't be able to feel his presence.
Obi-Wan allows Vader to strike him down, and, because through the Force the darkness of space cannot claim a victim, his body mysteriously vanishes the moment he dies. At the climax of the film, during the Rebel attack on the Death Star, Obi-Wan speaks to Luke through the Force to help him destroy the battle station.
Obi-Wan fakes his own death and goes undercover as his own 'killer', Rako Hardeen, so he can infiltrate Moralo Eval's plot to kidnap Chancellor Palpatine.
A year later, in 4 ABY, with his health rapidly declining, Yoda died of old age when Skywalker returned to see him. He became one with the Force, shortly before Luke redeemed his father Anakin, who fulfilled his destiny as the Chosen One by killing Sidious.
It is revealed that it was all a plan made by Obi-Wan, Yoda and Mace Windu, who decided to fake Obi-Wan's death so he could pretend to become a member of a looming Separatist plot to kidnap Palpatine.
During the battle, Anakin, who had been known as the Sith Lord Darth Vader, was redeemed by Luke and brought balance to the Force. However, the redemption cost Anakin his life, having been mortally wounded by the Emperor, Darth Sidious, while killing his former Master.
Instead, the theory suggests that Padmé died because Palpatine killed her. By taking a closer look at how Anakin's transformation into Darth Vader is intercut with Padmé's death, a clearer picture emerges of how Padmé's death was more likely a planned-out murder as opposed to an accidental tragedy.
Qui-Gon: I cannot. My training was incomplete. As such, he can only ever materialize as a disembodied voice in the physical world. The other Jedi who have achieved oneness with the Force have disappeared upon death, such as Yoda, Obi-Wan, and Luke.
The Sith apprentice Darth Maul struck Qui-Gon down during the battle for Naboo, but the mortally wounded Jedi lived long enough to ask his Padawan, Obi-Wan Kenobi, to promise to train Anakin.
Both Star Wars: Episode III - The Revenge of the Sith and the Obi-Wan Kenobi series made it clear that he blamed himself for Anakin's eventual fall to the Dark Side. By making the ultimate sacrifice for his new student, he found redemption for this perceived failure.
In canon no Obi-Wan doesn't have kids. However, there is this theory where he and Satine had a child together but she hide it from him, knowing how it could ruin his jedi career. This child would be Satine's “nephew” Korkie Kryze…
Legend had it that Yoda—a Jedi who became Grand Master—was trained by N'Kata Del Gormo. A Force-sensitive Hysalrian, N'Kata Del Gormo was trained in the ways of the Force and achieved the rank of Master within the Jedi Order.
Kylo Ren dies on Kef Bir (the ocean moon of Endor) shortly after Rey deals a mortal wound during a lightsaber duel on the wreckage of the second Death Star. Though Rey Force-heals him, saving his life physically, this blow, coupled with the memory of his mother and father, destroys the man known as “Kylo Ren” forever.
Anakin Skywalker/Darth Vader was 45 years of age when he died. People ask for Anakin's / Vader's age at various times in his life, and I've made a timetable for major events in his life and his age at that time.
The canonical comic Star Wars: Darth Vader #7 confirms the younglings' deaths caused Anakin grief, self-loathing, hatred, and pain, fueling his descent even further into the Dark Side.
Obi-Wan spared Anakin despite knowing killing him would "burn his heart to ash" and feeling regret for what Anakin could have become. Obi-Wan's decision to spare Anakin was influenced by the dark feeling that accompanied Emperor Palpatine's arrival, preventing him from finishing him off.
The purpose of this deception was for Obi-Wan to be able to go undercover as the bounty hunter Rako Hardeen while everyone believed him dead, so that he could uncover a plot to kidnap Chancellor Palpatine.
The duel ended with Obi-Wan's death and the disappearance of his body (we would later find that he had turned into a Force ghost), and Luke had to come to terms that his mentor is gone.
Obi-Wan's clone troopers betrayed him, opening fire seemingly without cause. The clones had been issued Order 66 -- the extermination of all Jedi -- from the Supreme Chancellor, who in reality was Sith Lord Darth Sidious. Obi-Wan survived, however, and made contact with Yoda, though no other Jedi had reported back.
