Submarine in a Robo-Factory: Comic Book Scene

Comic book style illustration of a sleek submarine entering a vast robot factory. Bold black ink outlines, high-contrast cel shading, and halftone textures give a retro hero vibe. The submarine features riveted steel hull, glowing amber portholes, a periscope, and a rounded sonar dome. Surrounding it are towering robotic arms, conveyor belts, welding torches, steam vents, and pulsing neon lights. The factory is a maze of pipes, girders, and chrome machinery, bathed in blue-green ambient light with orange hazard glows. A dynamic low-angle perspective emphasizes scale as sparks fly and mechanized workers awaken. Include classic comic-book onomatopoeia like WHIRR and CLANG in bold jagged lettering, with panel-like framing or burst effects to enhance the action.
