Epic cinematic low-angle full body shot of a colossal elegant female mermaid mecha robot standing in the ocean. She has a sleek pearlescent white and silver armored body covered in intricate fish-scale plating with glowing cyan and turquoise bioluminescent energy lines running through every segment. Helmet features a streamlined visor and large translucent fin-like crest extensions. Her long flowing cape is made of translucent cyan energy ribbons that look like water and seaweed. Lower body is a powerful articulated mechanical mermaid tail with large caudal fin, covered in the same glowing scale armor. Feminine powerful pose, one arm raised high, the other slightly extended. Standing in shallow crashing ocean waves on a rocky shore, misty coastal cliffs in the background, dramatic stormy sky with strong god rays breaking through dark clouds, floating bioluminescent particles and water droplets in the air. Hyper-photorealistic CGI, majestic and ethereal atmosphere, Pacific Rim meets Little Mermaid aesthetic, 8k, cinematic lighting, highly scales and energy effects, [ethereal-fantasy-style]
