A humanoid robot that transforms into an airplane, featuring a black metallic finish with blue metallic lines. This is a mecha design of a justice-seeking combat robot, equipped with a heavy full-armor chassis with boxy angular frames and exposed cables, caterpillar tracks as legs, a cylindrical head sensor that glows as it locks onto a target, wielding a beam-edged chainsaw weapon that sprays sparks when slashing. It is also equipped with an anti-missile catapult and a thick shield, soaring over a swirling sandstone desert under a dramatic overcast sky. Dust and oil stains are visible on its scarred armor. The scene adopts a cinematic dynamic angle, with intense amber sunset lighting casting long shadows, showcasing gritty realism and kinetic energy, along with volumetric sandstorm particles mixing with sparks and smoke.
