Hydrokinesis

Hydrokinesis is the ability to create, control and manipulate liquid water and mold it and other liquids into various shapes and forms.

With this ability, a mermaid can mold the moisture in the air as they want and control water pressure. It also allows mermaid to levitate and break ice and mystically multiply the water molecules, creating more water. The hand movement for this power is a free flowing hand between a rigid hand and balled-up fist. This may represent the state of water in between frozen and boiled. It may also represent the flowing movements of water and the movement of molecules in the liquid state.

If a mermaid with this power is in the Moon Pool during a special planetary alignment on a Full Moon, it could be enhanced to Aerokinesis.
