Time Machine Rooftop Showdown in Comic Style

High-energy comic book panel of a futuristic time machine on a gleaming skyscraper rooftop at dusk. A hero in a trench coat and goggles activates a chrome retro-futuristic device glowing with neon blue time energy. The city skyline stretches below, glass towers bathed in purple and cyan reflections. Bold black ink outlines, Ben-Day dot textures, and dynamic speed lines convey motion. A dramatic low-angle perspective, strong shadows, and punchy color blocks give a classic superhero vibe. Include speech bubbles with bold lettering: Time Jump! Hold On! The time machine has gears, coils, a glass time chamber, and glowing runes. Nearby are a railing, control panels with dials, and exposed vents. The overall mood is thrilling, cinematic, and distinctly comic book style.
