While searching for replacement parts on Tatooine, Qui-Gon discovers a slave boy, Anakin Skywalker, who is extraordinarily strong in the Force; a test of his blood reveals that his midi-chlorian count—a measure of Force potential—is the highest ever detected. Qui-Gon is even more intrigued when Anakin's mother, Shmi, tells him that the boy had no father. Realising Anakin might be the "Chosen One" of Jedi lore destined to bring balance to the Force, Qui-Gon bets Anakin's freedom and the spaceship parts on a pod race, which Anakin wins. The entourage leave Tatooine, but not before Qui-Gon is attacked by an unknown Sith Lord, whom he fights off. Upon returning to Coruscant, Jinn asks the Jedi Council to allow Anakin to be trained as a Jedi. Master Yoda senses fear in the boy, and the Council refuses his request. Undaunted, Qui-Gon vows that he himself will train Anakin when Obi-Wan becomes a Jedi Knight.
