A colossal primordial lava golem, with a molten core pulsating visibly beneath a fractured, rocky exterior, charges through a devastated futuristic cityscape. Molten cracks spiderweb across its surface, leaking streams of liquid fire. Its fiery fists leave trails of smoke and ash in the air as it rampages, steam hissing from the searing heat on contact with rain-soaked ruins. Skyscrapers crumble under its might, glass facades melting and twisting, while metallic structures warp and buckle. The corruption of raw elemental fury and molten chaos blends with the shattered remnants of human innovation, crafting a vivid tableau of destruction and otherworldly power.
