Underwater MPD Police Robot Test

Create a photorealistic, vertical composition image of a futuristic Japanese Metropolitan Police Department heavy humanoid robot undergoing underwater resistance testing in a clear blue swimming pool. The robot is large, bulky, and tactical in appearance, constructed from angular white and dark blue armor plates, revealing black mechanical joints, hoses, pistons, bolts, and sensor modules. The head is a rectangular multi-camera sensor bar with 4 large circular glass lenses on the front, mounted on a robust mechanical neck, with a small vertical antenna-like mast visible on the right shoulder/back. The robot features 3 prominent dark armor plates with white markings: the chest panel displays “警視庁” and “MPD”, the left shoulder/arm shield displays “警視庁” and “MPD”, and the right shoulder/arm shield displays “警視庁” and “MPD”. Add red translucent emergency light bars on top of the two shoulder shield units. Depict the robot partially submerged beneath a shimmering water surface, surrounded by dense air bubbles, splashes, water droplets, and shimmering caustics on the armor. Use a close-up, low-angle front view, with the torso centered, arms extended to the sides, and the sensor head positioned in the upper third of the frame. Lighting should be bright pool sunlight with high contrast, blue reflections, sparkling highlights, and realistic refraction effects, with a shallow depth of field for the pool background. Style: ultra-detailed sci-fi mecha realism, Japanese police robot concept art, clear mechanical textures, cinematic action still, no people, and no other text besides the visible “警視庁” and “MPD” markings.
