Mahiru

appeared in the Kakashi Gaiden arc. Mahiru is an Iwagakure ninja who was sent to scout the area in which Team Minato was traveling. He employed about twenty shadow clones against the team, only to have all of them destroyed by Kakashi's Chidori. However, in the end he was able to counter the Chidori and would have succeeded in killing Kakashi without the intervention of Konoha's Yellow Flash. He is then killed, but not before expressing regret for not running away when given the chance.
