Attack on Titan Levi wallpaper, dark-themed anime style, with low-saturation black and gray tones where only the cloak and sword emit a cold green tint. Levi, wearing the Wings of Freedom cloak and wielding twin blades from the Omni-Directional Mobility Gear, has a fierce gaze. The background features a weathered colossal wall and sharp scratches, creating an overall hard-hitting tension and strong visual impact.
