Users are able to create and transmit their chakra into these receivers for a variety of purposes. Black receivers are said to be a trademark of the Rinnegan. Wielders of the dÅjutsu are able to generate the rods from their own bodies, usually from the palms of their hands. However, there have been several instances in which black rods were produced through other means. (The best known wielders of the Black Recievers are Pain, Madara, Obito, and Kaguya)
