Both episodes deal with themes of identity, loyalty, and the struggle between light and darkness. In Episode I, the introduction of Anakin Skywalker, a young slave boy who becomes a Jedi Knight, sets the stage for the internal conflict between the light and dark sides of the Force. This theme is revisited in Episode V, where Luke Skywalker, Anakin's son, grapples with his own destiny and the revelation that Darth Vader, the embodiment of the dark side, is his father.
