外星凝胶变身生化巨人

Cinematic sci-fi action scene in a ruined, dusty post-apocalyptic city street. A young man kneeling on the cracked pavement touches a glowing, luminescent alien slime/gel. The substance rapidly coats his hand, transforming and expanding across his body with pulsing neon-green energy veins. He grows into a massive, muscular white-armored biopunk titan. Fighter jets fire missiles at him as he morphs his arms into a giant energy blade and a heavy cannon shield, leaps into the air, and blasts off into the sky leaving a trail of white smoke. Photorealistic, cinematic lighting, high-budget Hollywood visual effects style, 4k resolution.
