Koala Hero in the Bunker

Comic-book style illustration of a koala hero inside a dim, retro-futuristic bunker. The koala stands center-frame in a heroic pose, wearing a tattered cape and a small pilot helmet, with a determined expression. Thick black ink outlines, dynamic motion lines, and bold panels with halftone shading. The bunker features riveted metal walls, hanging cables, crates, and a glowing control console casting greenish light. Use dramatic perspective with foreshortening, high contrast, and a limited palette of greens, blues, and grays. Include speech bubbles or caption boxes in classic superhero style to enhance the old-school vibe. The image should feel like a page from a vintage sci-fi comic.
