Doomsday horror style. A surreal digital painting of a colossal mechanical titan emerging from toxic wastelands, its body composed of rusted metal and decaying machinery. The central figure towers over a desolate cityscape, with glowing red eyes piercing through the smog-filled atmosphere. Streams of oil and corrosive fluids drip from its joints, creating dark pools below. The background shows a blood-red sky with ominous black clouds, while scattered human settlements cling to life in the shadows of the behemoth. Industrial debris and broken technology litter the ground, telling tales of a fallen civilization.
