Kedōin Clan

The Kedōin clan is a small clan led by Agari Kaisen. Its members have the ability to copy someone's appearance, so well that it can't be exposed by ninken. However, they cannot copy techniques and other abilities. After a few days the clan member who used the technique returns to normal.

The clan was first introduced in a filler arc when Kiba Inuzuka, Hinata Hyūga and Naruto Uzumaki go on a treasure hunt mission. Agari's servants copied Naruto, Kiba, and Hinata's appearances and left them trapped in the cave while they left to go "mess up their village." The one posing as Naruto gave the real one a hard time and Kiba managed to take down Agari and the Kedouin clan members impersonating him and Hinata. Naruto finally defeated his impostor using the Shadow Clone Technique. Moments later in Tsunade's office, Tsunade revealed that she hired Agari to test the genin's teamwork and to see if they should be sent back to the Ninja Academy or not. Naruto, Kiba, and Hinata passed and collected the treasure chest, which contains the bill for Tsunade.
