The Drowned

The Drowned, originally Batwoman Bryce Wayne from Earth-11, is a Dark Knight from the Dark Multiverse who transformed herself into an Atlantean hybrid to conquer the world. Driven by revenge for her lover's death and distrust of metahumans, Bryce waged war on Atlantis, killed Aquawoman, stole her trident, and stole her trident, and, in a final act of desperation after her world was drowned in retaliation, engineered a powerful, hybridized army of sea creatures known as the Dead Waters. As The Drowned, she now commands these creatures and has established control over the world's oceans, eventually aligning herself with the villain Barbatos
