Qui-Gon Jinn is a Jedi Master appearing in Star Wars: The Phantom Menace. He is currently training Obi-wan Kenobi. Although a master, he is not a member of the Jedi Council due to his defiance of the council and unwillingness to follow the Jedi code.
He is the Jedi who first discovers Anakin Skywalker as a slave on Tatooine and the young child's unusually high midichlorian count and sensitivity to The Force. He wins Anakin's freedom from Watto through betting on Anakin winning the Boonta Eve pod race. He is convinced Anakin is the person spoken of in a Jedi prophecy that will bring balance to the force.
