Pôster de Ação Manga com Punhos Mecânicos

Hand-drawn manga poster style with rough ink lines and dramatic cross-hatching. In the center, an original [silver-haired fighter] in a black combat suit radiates an exploding [cyan lightning and plasma aura]. Massive mechanical piston fists, heavy industrial gauntlets, and turbine-structured robotic fists attack from all directions, covered in heavy metal textures, oil stains, exhaust smoke, and billowing steam. Composition forms a radial tornado of mechanical fists converging on the central figure using extreme fish-eye perspective and explosive dynamic speed lines. Visual effects feature shockwaves, flying sparks, and pressurized steam bursts. High-contrast color palette of black, white, brass orange, and vivid cyan. Impactful single illustration with no text.
