Third Great Beast Arc

While going through a standard checkup with Tsunade, Naruto learned that Rock Lee's recovery from his injuries during the Chunin Exams was still questionable. Later, Naruto and Tenten went to check on Lee just in time to see him in a practice match against young prodigy named Yagura. To Naruto, Tenten, and Guy's amazement, not only was Yagura able to push Lee back in taijutsu combat, but was also able to use an advantage taijutsu technique to nearly break Lee's ankle. Later when Naruto and Tenten were worrying about Lee's well-being, Neji convinced them to have faith in Lee as Neji had learned, stating bluntly that Lee has the potential to surpass any prodigy despite his shortcomings because of his dedication.

Later when Guy went on a mission with Yagura, it was discovered that the boy with Guy was actually an impostor. Tsunade quickly sent Neji, Tenten, and Naruto to go after Guy. Tsunade also decided not to tell Lee in fear he would follow them despite his ankle injury. Upon catching up with Guy, it was discover that he was already captured by a ninja team of brothers who wielded a unique Puppet Technique that controlled wooden training dummies and were on a mission of revenge against Guy for their father's death. While Naruto and the team managed to fight back the dummies, Lee surprisingly showed up and rushed to aid his sensei. As Naruto the team began to tire, Guy and Lee managed to defeat the brother's dummy fortress and break the jutsu. Afterwards, Guy revealed to everyone the story behind his battle with the brothers' father, making the brothers realize that their father did have content for Guy, but respect. This meant their desire for revenge was pointless.
