1980s comic book cover featuring a chrome-skulled vigilante named Glitterkill, standing under a glowing disco ball in a neon-lit alley. The character wears a shimmering trench coat with refracted light patterns, glowing eyes, and floating geometric cubes around them. Bold retro typography displays the title "GLITTERKILL" at the top, with the tagline "They kill with rhythm!" in stylized disco font. Background includes fog, graffiti, and synthwave colors—purple, magenta, electric blue. Art style mimics vintage Marvel and DC covers from the 1980s, with dramatic shadows, halftone texture, and pulp action flair.
