Naruto Episode 22
As they leave, Rock Lee appears again and challenges Sasuke to a battle. Initially refusing, Sasuke changes his mind when Lee effortlessly defeats Naruto. Even Sasuke’s Sharingan is no match for Lee’s taijutsu. Before any serious harm can come to Sasuke, Lee’s sensei and the self-proclaimed eternal rival of Kakashi Hatake, Might Guy, appears and stops the attack. After assigning Lee a punishment, the two leave, allowing Team 7 to proceed.
