Cyberpunk Poseidon in Neon-Unterwelt

Majestic cyberpunk Poseidon emerging from bioluminescent depths of underwater metropolis, mechanical trident crackling with electric blue neon energy. Holographic circuit patterns pulse across weathered skin, digital barnacles and fiber optic kelp adorning muscular frame. Towering chrome spires pierce ocean floor behind him, casting synthwave shadows through murky waters. Neon coral reefs glow in electric purple and cyan, while schools of robotic fish dart between floating screens. Dramatic low-angle shot captures godlike presence against backdrop of sunken skyscrapers wrapped in luminous cables. Moody underwater lighting creates ethereal atmosphere, mixing organic textures with sleek metallic surfaces in dystopian aquatic realm.
