Yamato is a member of Konoha's ANBU, and a younger peer of Kakashi Hatake. He is also the temporary leader of Kakashi's team, and one of the main protagonists of the series. "Yamato" is actually a codename given to him by Tsunade for the purposes of joining Team 7, his real name being Tenzo. Yamato, however, seems to prefer going by his codename while near his teammates, although Kakashi still calls him Tenzo.
