Kenobi discovered the young Anakin Skywalker on the planet Tatooine and brought him back to the Jedi Temple on Coruscant. Following the loss of his own Master, Obi-Wan began teaching Skywalker the ways of the Force.
From there, he watched over Anakin's son, Luke Skywalker. Obi-Wan eventually trained Luke and joined him on a mission to confront Vader on the Death Star. There, in a final duel against his former student, Kenobi did not survive.
In an alternative storyline, Starkiller can face off against Obi-Wan on Tatooine.
Obi-Wan Kenobi was a brave and daring Jedi Master, never failing to do what was right. He was a diplomat just as he was a warrior, forming several friendships within the Jedi Order. However, for all of his skill, he was not able to understand his Padawan Anakin Skywalker - a failure that eventually led to the fall of the Jedi Order.
