Will Materialisation

The Will Materialisation is an ability that allows the user to manifest and materialise their "will" for different purposes.

Kaguya Ōtsutsuki
Kaguya Ōtsutsuki upon being sealed by her two sons formulated a plan that would result in her eventual resurrection. This led to the creation of the sentient-being Black Zetsu who, as an extension of her will, would enact this plan.

Karura
After her death, Karura's will inhabited her youngest son Gaara's sand, causing it to automatically protect him whenever he is in danger. Gaara's sand morphes to her apperance after this is revelead by his father.

Black Zetsu
Like its creator, Black Zetsu was also able to use this technique to subtly influence the thoughts of others, or forcibly make them do his bidding by directly channeling his will through them.

Madara Uchiha
Madara was able to use a variation of this technique that is instead be channelled through chakra receivers. He was not only able to remotely manipulate the actions of those embedded with the rods, but also manipulate the receivers imbued with his will telekinetically.
