Generate an image of a terrifying beast representing the Soviet Union during World War II. This beast is a gigantic, iron-bear hybrid with glowing red eyes and fur made of steel wool. Its powerful limbs crush everything in its path, and its roar echoes like a cannon blast. The background features a frozen battlefield with wrecked tanks and artillery pieces. Particles of snow, sparks, and shrapnel fill the air, enhancing the cold, ruthless atmosphere. The image is captured from a bird's eye angle, showcasing the iron-bear’s relentless advance through the desolation.
