The characters are defined by their relationship to each other. Neither is really anything consequential distinctively without the direct influence of the opposing characterization. They are ideological, thematic, figurative, and esoteric counterparts. Two halves to one whole. They are symbiotic, living and growing off of one another. If not for Obi-Wan Kenobi, Anakin Skywalker would be a talented slave in Watto's junk shop, flying the chickies around in his custom built speeder every JabbaDay. If not for Anakin Skywalker, Obi-Wan Kenobi would be merely a nameless, faceless, very typical, ordinary Jedi among a sea of Jedi. Their collective fates and destinies are forever intertwined and dependent on one another. Without Obi-Wan Kenobi there is no Anakin Skywalker. Without Anakin Skywalker there is no Obi-Wan Kenobi. They are Bonnie and Clyde. Fred and Ethel Mermon. Esther and Fred Sanford. Butch Cassidy and the Sundance kid. George and Gracie. Hawkhead and bitching. Kirk and Spock. Tonto and The Lone Ranger. Tarzan and Jane. They are Obi-Wan Kenobi and Anakin Skywalker.
