yes he did because if you saw the empire strikes back Luke goes to see Yoda on dagobah and you see him as a ghost there. at the end of return of the Jedi you see him with anakin and Yoda as ghosts
Yes, Obi-wan and Darth Vader fight twice. Once on Mustafar, where Obi-wan was the victor, and once on the Death Star where Darth Vader killed Obi-wan.
Obi-Wan proved that he was better than Darth Vader in The Revenge of the Sith when he defeats Vader when Vader was at his height in power. And the only reason Vader killed him in A New Hope was because Obi-Wan sacrificed himself to help the others escape.
Obi-Wan states to Darth Vader, "If you strike me down, I shall become more powerful than you can possibly imagine."
Obi-wan dies in Episode IV A New Hope because Darth Vader killed him.
Obi-Wan Kenobi's body disappears when Darth Vader strikes him down. This is because Obi-Wan has become one with the Force, achieving a state of transcendence known as becoming a Force ghost.
No, he does not. Darth Vader's first apprentice (Galen Marek/Starkiller) is killed by Emperor Palpatine/Darth Sidious.
Yes, but he didn't really die. If you watch the 4th movie (A New Hope) carefully, you'll see that his robe is empty (Vader steps on it). This is because, rather than letting himself be killed by Vader, Obi-Wan surrendered himself to the Force and vanished, a bit like how Yoda vanished when he died in the 6th movie (Return of the Jedi). That's also how Kenobi was able to reappear as a Force spirit throughout the movies.
"Obi Wan killed your father"
Yes, Darth Vader killed Obi-Wan Kenobi, but Obi-Wan's body disappeared because he learned from Yoda how to retain his identity after death and become part of the Force. This ability is very hard to not only learn, but to acquire as well
Weird as it may seem, Obi-Wan Kenobi was 57 years old when he was killed by Darth Vader.
Darth Vader's old master was Obi Wan.
Potentially. Vader and Obi Wan were about evenly matched during their fight on Mustafar, which is why it lasted so long. Initially, Vader had the advantage as Obi-Wan was not willing to kill home. Vader only lost the fight because he became reckless.
