Mecha Generating Crystal Shield

the prompt

A detailed anime style shot of a dark armored mecha robot standing on a vast futuristic rooftop, rapidly generating a large, intricate, glowing blue crystal shield in front of it. The shield quickly expands into a complex star-like structure, deflecting bright energy beams that impact its surface, causing light flares. In the background, a futuristic city skyline with towering, sleek buildings under a bright blue sky with scattered clouds. The camera slowly zooms in on the mecha and its expanding crystal shield.
