The Water Dragon
The ability to control water in any of its forms, gas, liquid or solid. She can manipulate the consistency to gain whichever form of water she desires, and it doesn't seem to matter if it's salt or freshwater. At full strength, she is capable of creating up to four water tornados in the middle of the ocean, combining them into a hurricane to hurl at her enemies if she wanted to. Or something as simple as making bubbles of water to float around for the entertainment of children can be done as well.Monstrous Body
From superior strength to lift something like a car with little strain, to her nearly draconic scales that cover a majority of her body naturally that can deflect blades and physical attacks. Adding on the benefit of breathing clearly underwater, and a strong tail that allows her to cut through her domain at high speeds and there is little doubt any enemy would survive. Teeth retract into fangs for all her teeth, and a thin membrane can be used to clean her eyes outside of blinking like a human. Her blood even has a paralytic effect to it that can stun enemies twice as big as herself.
