Thunderbird in a Neon Crystal Cavern

An epic thunderbird rendered in vibrant anime style, soaring through a crystal cavern. The colossal bird features iridescent blue, emerald, and gold plumage with sharp, glossy feathers and electric energy crackling around its wings. The cave is lined with glowing quartz crystals, pink, cyan, and violet light reflecting off jagged stalactites and a glittering crystal floor. Soft mist and floating motes illuminate the scene as lightning trails arc behind the bird. Dramatic perspective from below, wide-angle, dynamic motion lines, crisp linework, and high-detail shading to emphasize the energy and scale. Cinematic, fantasy, neon-lit atmosphere.
