For Image Generation:

PROMPT:
First of all generate a picture with your image in Nano Banana or Gemini.

Upload your picture and use this Prompt:

Create an ultra-realistic 8K cinematic scene in New York City during an intense battle. The attached real person is the main hero — maintain the exact facial features, skin tone, bone structure, hairstyle, and expression from the reference photo with zero alteration and no face swap. The hero stands confidently in the foreground, wearing modern tactical streetwear, ready to fight.

A massive green muscular giant villain roars in the distance, towering over destroyed cars and cracked pavement. Surrounding the hero are a squad of legendary champions:
• a masked acrobatic wall-climber in a red-blue tech suit
• a silent dark knight warrior with a flowing cape
• a flying solar-powered alien with a glowing chest emblem
• a red-gold armored tech genius with thrusters
• a patriotic super-soldier holding a vibranium-style shield
• a thunder-wielding Norse warrior holding a glowing hammer

Cinematic dust, broken rubble, dramatic lighting, volumetric smoke, lens flares, and high-contrast shadows. Camera angle low, heroic perspective. Hyper-detailed skin texture, realistic fabric, and polished metal reflections. Dynamic action movie atmosphere.
