A majestic giant mecha stands proudly atop a sleek skyscraper in a futuristic sci-fi city, its white and red armor glistening under the cinematic lighting of a golden sunset. The Mazinger Z-inspired bio-mecha's composite chest armor shines like polished metal, while matching arm and leg guards reflect the setting sun's rays. A crimson Z mark adorns the belt, as the mecha's fully enclosed shoulder guards gleam with metallic sheen. As it gazes out upon the cityscape, its extremely detailed eyes seem to pierce through the haze of plasma energy crackling around its body. The mecha's real texture material appears almost tactile, with dramatic shadows and highlights that showcase its ultra-detailed, anatomically correct physique. In this TR-style masterpiece, the golden ratio of perfect proportions is balanced by the symmetrical face and mature manga art style.
