A retro underground comic poster in impact burst halftone style. Use the reference only as a visual-system guide. Do not copy its exact character, pose, text, signature, watermark, or composition. The poster features a large main illustrated subject in the lower two-thirds, performing a chaotic action. An oversized diagonal prop crosses the torso or foreground. The upper band has huge condensed cream impact text (e.g. ZAP!, CRASH!, BANG!). A cyan rectangular backdrop separates the subject from the black field. A yellow jagged speech-burst corner shape adds asymmetry. Speech bursts, smoke puffs, starbursts, and impact marks fill the background. The palette uses carbon black, aged cream, hot orange, poster cyan, impact yellow, muted olive, and soft gray. The finish includes heavy paper grain, halftone dots, ink speckles, distressed contour edges, and slight misregistration. The layout is loud, cropped, and graphic. Avoid watermarks, signatures, logos, photorealism, 3D rendering, and glossy gradients. --ar 9:16
