In a full body shot from a low-angle perspective, Knull stands as a towering, emaciated deity amidst the primordial void of the deep cosmos. He is a ghastly figure with deathly pale, chalk-white skin stretched over a skeletal frame, featuring a sharp, angular face with sunken cheeks and a sadistic sneer revealing rows of needle-sharp teeth. His glowing, blood-red eyes pierce through an unruly mane of bone-white hair that floats like frayed silk. He is clad in living, pitch-black organic armor with a violent crimson dragon-like crest across his chest, wearing elongated clawed gauntlets and a tattered cape that dissolves into writhing shadowy tendrils. He grips the massive, jagged All-Black Necrosword, from which viscous, tar-like dark matter drips onto the void. The background is a swirling expanse of anti-matter and cosmic darkness. The atmosphere is one of absolute cosmic horror, characterized by a high-contrast palette of deep blacks and stark whites, with eerie red luminescence and a sharp, detailed anime illustration style.
