Create a dramatic and intense scene of an epic battle between Shadow the Hedgehog and Batman, set in a dark, urban environment illuminated by a full moon and flickering neon lights. Shadow unleashes his Chaos powers, surrounded by a fiery red aura, while Batman counters with his iconic gadgets and a flowing black cape. The backdrop includes a gritty Gotham-like skyline with towering buildings and swirling smoke. Use ultra-detailed textures, dynamic lighting, and sharp contrasts to emphasize the fierce clash between the two dark and brooding figures.
