This is an ability possessed by Madara Uchiha, allowing him to materialise his will, giving it physical form, to suit any given situation. Likewise, he can use this to infuse other beings with his will, as he did to create Black Zetsu by pouring his will to White Zetsu, describing it as a weaker version of himself. This ability also led to the creation of the chakra receivers. In addition to the other abilities bestowed upon them, these receivers can act as a conducter of his will, allowing him to control them remotely and, from a distance, infuse his will into anyone who has one in their body. This in turn, gives Madara control over their actions. Obito later demonstrated usage of this ability, creating and firing several chakra receivers from his body, which he could then channel his chakra through to preform other techniques.
