Clone vs. Clone: Mine are Better than Yours!
From series: Naruto
Naruto’s team joins Kabuto on their journey to the tower, but on the way, they are trapped by the genjutsu (illusion technique) of the Hidden Rain Village’s genin (low rank ninja), Oboro’s team. Not only do they lose energy by being forced to walk the same area repeatedly, they struggle in their fight against the numerous clones created by the technique. Naruto proceeds to beat each one of the clones, but their number does not go down.
