Umberlee

Goddess of the sea most often worshiped by sailors or people traveling by sea, out of fear of her destructive powers. She was known as a particularly malicious, petty, greedy, and vain deity who controlled the harshness of the sea while reveling in her own power and was not hesitant to drown people if she so pleased.
Avatar was a giant woman with the body colored like the sea, of blues and greens. Her hands had talons. Her elbows had fins and green hair of seaweed and kelp. Her white eyes were reminiscent of pearls, and her voice sounded like the fiercest sea storm, booming with breaking waves. The goddess appeared in that form to scare and impress the mortals on board of dying ships. The towering avatar wore jewelry made out of seashells, carried a trident, and was dressed in a flowing cape made out of countless pale-purple jellyfish. Umberlee's avatar laughed with malicious glee as she toyed with the doomed vessel.
Known as the Bitch Queen by sailors due to the moodiness of the ocean’s waves.
Umberlee was temperamental, evil, and malicious. She did not feel the moral obligation to honor any of her agreements or promises if the end result was not beneficial to her. That, and her desire for the valuables and excessive tributes, characterized her insatiable greed and cruelty. She was power-hungry and loved exercising it, toying with her worshipers. She fed her sadistic nature by destroying naval vessels and feeding shipwreck victims to her sharks while watching the others drown.
