An ancient aquatic behemoth, depicted in a swimming posture (body arched, tail swinging backward rather than upright), with sharp claws, fully webbed fingers, and broad, paddle-like flippers. It possesses reptilian eyes with vertical pupils, deep-sea features, gill slits on its neck and lower jaw, and faintly glowing bioluminescent tentacles/whiskers hanging from the sides of its head. Small, fin-like folds adorn its cheeks, resembling fish scales with a subtle iridescent sheen. Sharp dorsal fins, like those of a sailfish, line its back, and it has a long, eel-like tail.
