Mubi

was a Genin from Amegakure

Chunin Exam arc
In the second phase of the Chunin Exams, Mubi and his teammates used a number of different genjutsu to cause Naruto, Sasuke, Sakura and Kabuto to waste time and tire themselves out. After having them fight illusions for a while, Mubi and his teammates engage them. They quickly find out that what appeared to be the Konoha ninja were really just shadow clones in disguise, the real ninja having been resting. Mubi and his teammates are quickly defeated and did not pass the second phase.

Land of Tea arc
In the anime, Mubi and his teammates, under the leadership of Aoi Rokusho, where assigned by Amegakure to help the Wagarashi clan win the Todoroki shrine race held in the Land of Tea. While Oboro went to stall Idate, Mubi and Kagari prepped a ship for naval combat. After sinking Idate's ship, the Rain Genin went to battle Team 7 underwater, where they held the advantage. However, Naruto used his Rasengan training to hand them another humiliating defeat as the first part of the Rasengan training created a whirlpool that sucked Oboro's team into a trench. They are assumed to have survived because of their masks.

Rain Village arc
Mubi and his team are shown again in a flashback during Jiraya's interrogation of a Rain genin. They were part of a faction still loyal to the old Amegakure order who opposed Pain and were seen attempting to infiltrate the village. In the anime, it is indicated that he and his team were killed in the attempt.
