A captivating comic book cover showcasing a split composition between Batman and The Riddler, each facing off with expressions of intense determination. The Riddler stands on one side, facing a futuristic, dystopian Gotham City filled with neon-lit skyscrapers and cyberpunk elements. Batman, on the opposite side, is backed by a gritty, modern Gotham with shadowed buildings and subdued city lights. Between them flows a dark river, bridged only by a symbolic, crumbling structure that highlights the contrast between their worlds. The scene is rendered in high-definition portraiture, with photorealistic details capturing the intensity of their gazes and the stark differences in their personas. Sharp lighting contrasts illuminate Batman and The Riddler in distinct color schemes--one shadowed and somber, the other illuminated by cold, artificial light--intensifying the emotional depth and visual impact. The cover design blends symbolic and atmospheric elements, enhancing the iconic tension between the two characters and their opposing visions of Gotham.
