Obi-Wan Kenobi is a fictional character in the Star Wars universe. He is one of several primary characters in the Star Wars series. Along with Darth Vader, R2-D2, and C-3PO, he is one of the few major characters to appear in all six Star Wars films. He is portrayed in the original trilogy by Alec Guinness, in the prequel trilogy by Ewan McGregor and is voiced by James Arnold Taylor in the Star Wars: The Clone Wars film and television series. His role in the original trilogy is of a mentor, whereas the prequels see him as a central protagonist.
Obi-Wan Kenobi first appears in Star Wars Episode IV: A New Hope. Luke Skywalker, the film's main protagonist, had previously known him as a mysterious hermit called Ben Kenobi. Soon, Obi-Wan reveals himself to be an exiled Jedi Knight, and begins to tutor Luke in the ways of the Force, a mysterious energy field harnessed by the Jedi. In the prequel films, Obi-Wan first appears in Star Wars Episode I: The Phantom Menace as a Jedi padawan, or apprentice, and eventually becomes a Jedi Knight and mentor to young Anakin Skywalker, Luke's father. In Star Wars Episode II: Attack of the Clones, he is shown to have progressed from the rank of Jedi Knight to Jedi Master. Finally, in Star Wars Episode III: Revenge of the Sith, he becomes an experienced Jedi Master and Council Member, fighting in the Clone Wars alongside Anakin, his pupil and best friend. He holds these titles under the Galactic Republic until it is replaced by the Galactic Empire—due in large part to Anakin's betrayal—and he is forced into hiding.
Looking at these stars suddenly dwarfed my own troubles and all the gravities of terrestrial life. I thought of their unfathomable distance, and the slow inevitable drift of their movements out of the unknown past into the unknown future. H.G. Wells
Humankind has not woven the web of life. We are but one thread within it. Whatever we do to the web, we do to ourselves. All things are bound together. All things connect. Chief Seattle
