Act as a cybernetic marine biologist with 15 years of experience in deep-sea biomechanics. Design a hyper-detailed Midjourney portrait of a colossal leviathan fused with a sleek, futuristic robotic exoskeleton. The creature should have [GLOWING BIOLUMINESCENT PATTERNS] along its organic flesh, contrasting with the [POLISHED METALLIC PLATING] of its exoskeleton. Emphasize the [HYDRAULIC JOINTS] and intricate wiring that merge seamlessly with its muscular structure. The background should be a dark abyssal trench, illuminated only by the leviathan's eerie glow and the cold light of its robotic enhancements. Use a cinematic, high-contrast lighting style to highlight the fusion of organic and mechanical elements.
