Shadow Creature of Atlantis: Anime Underwater Scene

An eerie shadow creature glides through an ancient Atlantean city submerged underwater. In vibrant anime style with bold cel shading, the silhouette is a shifting, inky form with glowing sapphire eyes and wispy tendrils trailing like liquid. Surrounding ruins: coral-encrusted arches, submerged statues, and bioluminescent sea flora. Sunlight filters through the blue-green water, creating shimmering caustics and floating bubbles. The perspective is dynamic, slightly from below, with motion lines and dramatic depth that convey mystery and danger. Palette: deep blues, teals, purples, and electric cyan highlights. Mood: haunting, ethereal, adventurous.
