Baru Uchiha (うちはバル, Uchiha Baru) was a shinobi of the Uchiha clan.
Born to the Uchiha clan, Baru was of its few members who were able to awaken the Sharingan in his youth, as well as his own Mangekyō Sharingan.
During the continuous struggle between shinobi clans, Baru and his clansmen faced an opposing force who quickly wiped out Rai Uchiha's comrades with a trap. However, Rai nullified the outcome by sacrificing one of his eyes in order to use Izanagi. After the enemies were defeated, Baru challenged Rai for the leadership of their group and killed him using his own Izanagi. However, he was killed by his other clansmen when he was just celebrating his victory.
