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 demigod offspring. Zeus also has hydrokinetic abilities, though he only controls the rain and clouds.

## Description

Hydrokinesis is a very powerful ability to have. One with the ability can create, shape and manipulate water or anything liquid-based , inorganic compound with liquid, gas (steam, water vapor), and solid (ice) states, including changing them from one state to other. This involves water itself, ice in any form, sweat, blood, steam, water pressure, poison, and other variations. With this power, a user can manipulate water-related weather such as blizzards and rainstorms. Users can also control water in all three of its physical forms and even manipulate the liquids inside another human's body to unleash gigantic tsunamis and tidal waves, users can harden water into an almost solid shape, and can use this power to walk on water, by increasing the surface tension of the water to the point where it is solid enough for other objects to stand on. Users can also create extremely durable water shields and huge solid constructs that obey thier will. It seems to be an ability possessed by the children of Poseidon, and his Roman counterpart Neptune. This ability can also be possessed by powerful children of Zeus, and his Roman counterpart, Jupiter as they are able to create strong storms that can generate rain.

## Instances

### Ocean Demigods

* Caspian, unknowingly, used hydrokinesis to pull Jeremy Barrera into a fountain.
* Caspian used it to defend himself (again unknowingly) from Larissa Sanders by shooting water spouts out of the toilet, when she tried to dunk his head in the toilet.
* When fighting with Lyssa, the goddess of rage, Caspian controlled the ocean waves to help him in the battle.
* After Zamaya Reynoso struck Naomi with electricity, Naomi angrily retaliated by summoning all the water out of the creek into an icy water typhoon to throw at her.
* Caspian used it to control the sea water in fossilized shells to clean out the horses' stables at Geryon's Triple G Ranch.
* Caspian 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.
* Caspian 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 Thief of Thunder and Lightning*.
* Caspian and Naomi used it to douse the fires in the battle at camp.
* Naomi was able to still the waters so Larissa could drive her mother's chariot across the water to Los Angeles.
* Caspian controlled the waters in the River Lethe and willed himself to stay dry when submerged.
* Caspian can make bubbles which let other people breathe underwater as seen in *The Ocean of Beasts* and *The Final Deity*. Both times, he created water to let Leo breathe.
* Any child of the ocean can walk on water.
* Any child of the ocean can breathe under water.
* Both Moana and Caspian partially used water when they created their own personal hurricanes on separate occasions, Caspian in *The Final Deity* (against Hyperion) and Moana in *The Child of Nethuns* (against the legion of ghosts).
* Any child of the ocean has used it to increase the water viscosity to a level where it was almost solid. They can use it to form shields or stand on water as if it were ground.
* Any child of the ocean can separate oxygen from water, making them able to breathe and create water bubbles when they are submerged.
* Any child of the ocean can create huge hands made of water from the Tiber River.
* Moana blew up the Victor family mansion's sprinkler system in *The Child of Nethuns*.
* Moana caused a humongous wave to break the Hubbard Glacier in *The Child of Nethuns*.
* Caspian manipulated Ahklys' poison when angry during the second war.

### Poseidon

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

### Zeus

* In *Caspian's Miscellaneous Myths*, it is revealed that Zeus once brought about a global flood by causing tremendous torrents of water to pour down from the heavens all over the world for nine days and nights, with Poseidon assisting him by rapidly raising seas' water levels. As a result, the entire world was flooded (except for the highest mountains), and most of the human race was destroyed. Deucalion and Pyrrha were among the few that survived this great calamity

## Limitations

So far, the only major limitation of hydrokinesis is when used against certain beings (like other sea deities) who have a superior will over water and can wrest control from the weaker one. As well as being in a location where water is not abundant, or battle against a person whose ability can overcome or counteract water (e.g. Pyrokinesis).  Also it appears that beings with hydrokinesis can control or create ice to a certain extent. Seen when Moana used the ice and snow around him to make an icy hurricane, as he does during the battle in Alaska in *The Child of Nethuns*.
