Hyper-detailed digital painting of a colossal white armored mecha knight standing on a misty, rocky battlefield. The suit is sleek and angular with ivory-white plates, dark inner frame, gold accents, and jagged shoulder spikes. It wields a long double-edged blade in one hand and has large wing-like panels or shield attachments on the back. A circular halo ring floats behind its head. Blue ambient glow illuminates the joints and vents, with subtle falling petals or sparks and wisps of fog around the feet. Dramatic backlighting and cinematic, anime-mecha style with intricate circuitry textures, high contrast and epic scale.
