School monster invasion mecha transformation AI Image Prompt

The video opens on a school sports field under an overcast sky. A giant monster invades, and students flee in panic. The protagonist, a young male, remains calm as someone shouts, 'Stop pretending and run!' He mutters, 'So it has come.' As he walks forward, a black snake-like mechanical device with red glowing effects emerges on his arm. It activates, and black-and-red mechanical bones begin to cover his entire body, accompanied by golden arcs and lava-like red light, with armor plates interlocking and reassembling. Finally, he transforms into a black-and-gold mecha warrior with spikes and flame effects, unfolding metallic mechanical wings on his back, his head covered by a knight helmet with glowing red eyes. He raises his hand, releases purple energy, defeats the monster, and utters, 'Done.' The video uses cinematic camera movement and sci-fi transformation effects to create a strong hero fantasy feel, with a low-saturation gray-blue tone and film grain, fitting the theme of 'male fantasy moment.'
