Nautilus Kane wasn’t always a hero—he was once a marine biologist whose submersible malfunctioned during a deep-sea expedition. Trapped 20,000 feet beneath the surface, Kane discovered an ancient alien lifeform entwined with bioluminescent coral. In a desperate attempt to survive, the alien merged with him, altering his biology forever. Kane now breathes both air and water, his body adapting to crushing depths and extreme cold. His skin emits a soft glow, calming sea creatures and illuminating the darkest ocean floors.

With enhanced strength and agility, Kane can move effortlessly through deep currents. He communicates telepathically with marine life, forging alliances with sharks and squid alike. His greatest gift is the Abyssal Shield, a shimmering forcefield that protects himself and others from danger. Now, as an underwater astronaut, Kane explores the uncharted trenches, helping stranded explorers and ensuring the ocean’s mysteries remain safe from human exploitation
