Bat Controlling: Doppelganger

After exercising dominance over a number of bats, the user can command them to congregate into a single, fluttering mass and then project their chakra towards them. Through this, the "colony" of bats take on the appearance of the user and gain the ability to perform ninjutsu. Furthermore, since the bats act as an intermediary, the technique costs less chakra than the traditional to produce. When the chakra projection is severed, either through the clone's defeat or the user releasing the technique, the bats disperse.
