digital wallpaper portrait of a brutal cyborg samurai supervillain, anime-inspired, in a comic book style, 8k resolution, similar to marvel comics, set against a dark backdrop with muted tones, showcasing an epic composition that is both dramatic and emotionally profound, highly intricate digital painting featuring flaws like low-quality jpeg artifacts, and elements like poorly drawn hands and face, with features such as mutations, blurred and dehydrated appearance, disproportionate anatomy, presence of extra limbs or missing body parts, disfigurations, distorted proportions, and malformed limbs, including a long neck, unintentional cloning of facial features, intended distortion and morbid elements, exaggerated and unsettling features, focusing on the dark and villainous aesthetic without the inclusion of any camera marks, names, signatures, watermarks, or logos.
