A towering, monstrous crab emerges from the stormy ocean, dwarfing the city skyline behind it. Its colossal claws and glowing, menacing eyes pierce through the mist, casting an eerie light over the dark waters. The crab's armored body is textured with a mix of wet, rocky surfaces, covered in barnacles and seaweed, giving it a primal and ancient appearance. The sky is stormy and dark, with lightning illuminating the silhouette of the creature. Below, a group of shocked onlookers stands at the water's edge, their silhouettes dwarfed by the sheer size of the beast. The scene is cinematic, filled with tension and awe as the massive crab looms over the city, a perfect combination of creature-feature terror and apocalyptic destruction.
