Roboko

A robot modeled after Satoko Kusagakure, created by Marin Izutsumi. For a time, it became even more favored by Konoha Koga than the real Satoko, earning her great trust. Although it could not use the leaf technique, it was able to fire a powerful beam and was more considerate than Satoko. Despite being an artificial intelligence, its words and actions were notably virtuous, and it was regarded by Konoha as the "ideal partner." However, out of jealousy, Satoko turned the robot into a leaf. The loss sent Konoha into a period of "partner loss" depression. Later, a mini-sized second unit was created.
