Hydrokinesis

Hydrokinesis is the ability to manipulate and control water. This is a trait shared with water nymphs (Naiads, Oceanids, and Nereids), aquatic deities like Poseidon, Oceanus, and their offspring.

Forms of Hydrokinesis
As seen when performed by Percy Jackson and Poseidon, hydrokinesis is a very powerful ability.

Percy Jackson

 * Percy, unknowingly, used hydrokinesis to pull Nancy Bobofit into a fountain.
 * He used it to defend himself from Clarisse La Rue by shooting water spouts out of the toilet, when she tried to dunk his head in the toilet.
 * When fighting with Ares, the god of war, Percy controlled the ocean waves to help him in the battle.
 * In The Lightning Thief (film), Percy used high density water to make a trident.
 * After Thalia Grace struck Percy with electricity, Percy angrily retaliated by summoning all the water out of the creek into an icy water typhoon to throw at her.
 * Percy used it to control the sea water in fossilized shells to clean out the horses' stables at Geryon's Triple G Ranch.
 * Percy used water from his own body to create a large blast of water at Mount Saint Helens. This is a very dangerous ability that left Percy very dehydrated and required him to rest for an extended period of time.
 * He willed himself to stay dry when walking through a river in the Labyrinth, as well as willing himself to get wet when he is about to get picked up by the coastguard in The Lightning Thief.
 * He used it to douse the fires in the battle at camp.
 * He was able to still the waters so Clarisse could drive her father's chariot across the water to Manhattan.
 * He controlled the waters in the River Lethe.
 * He can walk on water.
 * He partially used water when he created his own personal hurricane on two occasions, in The Last Olympian and in The Son of Neptune.
 * He used it to increase the water viscosity to a level where it was almost solid. He can use it to form shields or stand on water as if it were ground.
 * He can separate oxygen from water, making him able to breathe and create water bubbles when he is submerged.
 * He can create huge hands made of water from the Tiber River.
 * He blew up the Zhang family mansion's sprinkler system in The Son of Neptune.
 * He caused a humongous wave to break the Hubbard Glacier in The Son of Neptune.
 * Percy was able to put an air bubble around himself and Annabeth in the Long Island, so they could kiss. This is after their fellow campers pushed them in. This is later seen as Arachne puts this scene in one of her tapestries in The Mark of Athena.

Poseidon

 * In the war against Oceanus, Poseidon used all his power to keep the war under the sea from creating Poseidon.jpgble disasters, like hurricanes, above the seas.
 * He demonstrated an incredible amount of power over water when fighting Typhon with the other gods.
