Giant mechanical robot transformation from airplane

9:16 vertical smartphone filming perspective, realistic bystander live-recording footage, subtle handheld shake, automatic exposure shifts, focus pulling, authentic environmental audio capture, distant city skyline clearly visible.
An airport runway situated near the city center, with a background of a modern metropolis filled with dense high-rise buildings. A large twin-engine wide-body passenger jet is in low-altitude approach preparing to land, landing gear fully deployed, engines producing a thunderous roar.
At the precise instant before touchdown, the aircraft fuselage begins mechanical structural reconfiguration—wings folding and disassembling, fuselage panels sliding and expanding, complex metal components aligning with precision, hydraulic mechanisms extending and rotating, gears and armor plates reconstructing at high velocity.
Highly intricate industrial-grade mechanical transformation animation, realistic metal textures, pronounced sense of mass and weight, extraordinarily precise mechanical details.
The aircraft completes its transformation into a colossal metal robot; upon landing, it instantly fractures the runway, sending gravel flying and shockwaves radiating outward.
The robot then charges into the city at high speed, its footsteps shattering the asphalt pavement, toppling streetlights, overturning vehicles through vibration, shattering building glass, and filling the air with swirling smoke and dust.
Ultra-photorealistic cinematic-grade imagery, realistic physics-based destruction system, dynamic lighting and shadows, particle effects, and awe-inspiring explosion visuals.
Overall style strictly maintains a “genuine smartphone live-recording aesthetic,” yet delivers Hollywood-level visual effects and IMAX-grade detail.
