A detailed photograph of a squirrel dressed as Batman, with an intricately designed black costume, striking a heroic pose. The background features a devastated cityscape under a tumultuous, stormy sky. Captured in 8k ultra-high-definition using a DSLR, the image showcases soft, diffused lighting, maintaining high quality with a touch of film grain for texture, reminiscent of a Fujifilm XT3 camera capture. The scene is infused with a sense of cinematic drama, adding to the squirrel's gallant persona.
