Hydrokinesis

Hydrokinesis is an ability that allows the user to control, manipulate, create, and morph water. What makes this ability so different from Water Release is that it uses no chakra, instead it is a physical ability that can be trained for better performance. But since it is a physical ability, the user fatigues when using this ability, but can use chakra to enhance their physical abilities to counteract this weakness. Hydrokinesis can be used with regular Water Release and physical damage in greatly increased because of Hydrokinesis being a physical ability.

Aoi Uchiha Usage
Aoi Uchiha was the first to obtain this ability when facing off against Itsuki. While unconscious, Aoi was visited by this man, the man said a few things to him and gave him extra chakra, Hydrokinesis, and the Trident of Poseidon. The Trident of Poseidon enhances his ability in Hydrokinesis so he will have better usage of the ability.
