Cyberpunk Kraken Boss in Neon City

A colossal cyberpunk Kraken fighting in a rain-soaked neon city. A whale-sized sea monster with chrome plates, glowing circuitry along its body, and bioluminescent teal and purple tentacles; drones orbiting its head like satellites; cables and data streams trailing from limbs. It lurks in a neon-lit harbor and rises from a dark ocean, towering over flooded streets lined with holographic billboards and megacity skyscrapers. Overlaid on the scene are cinematic video game UI elements: health bar, minimap, aim HUD, and particle sparks from electric attacks. The atmosphere is moody cyberpunk noir: rain, reflections on wet chrome, neon signs in kanji and English, flying cars, and a stormy night sky. The image should look like a high-detail concept art or a AAA video game boss encounter, suitable for 4K rendering.
