A heavily mutated post-apocalyptic cow standing in the ruins of a shattered wasteland. The cow is massive, rugged, and terrifyingly majestic — its hide is cracked and tough like volcanic rock, with glowing bioluminescent veins pulsing beneath the surface. It has a double row of horns spiraling back from its forehead, jagged and uneven, like old rebar twisted by heat. Its eyes burn a dim toxic green, leaking faint smoke. Style: hyper-realistic, dark sci-fi, gritty, detailed textures, cinematic lighting.
