Trained by the Jedi Master Yoda, Obi-Wan Kenobi learned the ways of the Force and became a Jedi Knight. He successfully defended the Old Republic in the Clone Wars and was hailed as a hero. He took on his own apprentice, the young Anakin Skywalker. But Obi-Wan was not yet ready to pass on the way of the Jedi, and his student became impatient with the rigors of Jedi training. Skywalker allowed himself to be seduced by the dark side of the Force. Taking the name Darth Vader, he pledged allegiance to the evil Senator Palpatine and went on to hunt down and kill the remaining Jedi Knights in the name of the Galactic Empire. Kenobi felt responsible for Skywalker's fall, and determined to stop his one time pupil. He confronted and defeated Vader in an epic lightsaber duel, leaving his broken body for dead.
