Qui-Gon is introduced in The Phantom Menace as a wise and powerful Jedi Master and the teacher of the 25-year-old Obi-Wan Kenobi. Unlike other, more conservative Jedi, he values living in the moment as the best way to embrace the Force. While other Jedi respect him highly, they are frequently puzzled by his unorthodox beliefs, and ultimately deny him a seat on the Jedi Council despite being among the most powerful of the Jedi. Obi-Wan remarks that Qui-Gon has been in conflict with the Council several times in the past.
Attack of the Clones reveals that he was trained in the ways of the Jedi by Count Dooku. In Revenge of the Sith, Master Yoda reveals to Obi-Wan that Qui-Gon's spirit has learned the secret of becoming one with the Force, which he teaches to both Yoda and Obi-Wan. In Star Wars Episode V: The Empire Strikes Back and Star Wars Episode VI: Return of the Jedi, both Obi-Wan and Yoda, as well as a redeemed Anakin, are shown to have fully mastered this ability after their deaths.
