科幻動力裝甲變身場景

Cinematic shot, medium shot. A woman standing in an empty, gritty concrete stadium wearing a casual hoodie. Suddenly, a mysterious, glowing purple-and-gold alien artifact on her wrist activates, spreading high-tech, organic-looking power armor over her body. The armor is sleek, black, and gold with glowing purple energy veins. Sharp, floating purple crystalline shards materialize behind her back. A large, monstrous, hulking alien creature charges at her from the shadows in the background. The scene is epic, high-budget superhero movie style, dramatic lighting, 4k, hyper-realistic, action-packed.
