Generate an image of a terrifying beast representing Great Britain during World War II. This beast is a titanic, armored bulldog with Union Jack motifs on its metal-plated body. Its eyes glow with an unyielding spirit, and its growl reverberates through the smoky, war-torn landscape. The bulldog stands defiantly atop a rubble-strewn battlefield, with bombed-out buildings and barrage balloons in the background. The scene is enhanced with sparks, debris, and particles, adding to the sense of grit and determination. The image is captured from a bird's eye angle, highlighting the bulldog's indomitable stance amidst the ruins.
