Powers
Alien nature that mimics both human and aquatic life, making her amphibious, with gills and webbed hands/feet. Superhuman swimming speeds. Survival at intense ocean pressures. Visibility in most watery conditions. Secretion of an oil that causes temporary blindness. Also, during periods of mating and birthing, Marrina would undergo intense physiological and psychological changes, become a savage, bestial killer with claw-like weapons, and later, a monstrously-sized serpent creature.
