Obito Uchiha was one of Kakashi's teammates in the manga exclusive Kakashi Gaiden. He was a 13-year old Chunin in Team Minato with Kakashi, Rin, which was led by Minato Namikaze. He's very similar to Naruto Uzumaki, goofy and desperate to prove he is a worthy ninja, mostly unrespected by peers and teachers alike. [naruto.wikia]
