Reimagine Spider-Man and The Flash as a dynamic character with a vibrant Super Saiyan hairstyle glowing red and gold, symbolizing the Speed Force. Set in a post-apocalyptic city, debris and lightning follow every movement as he leaps from collapsing buildings. Employ Unreal Engine v5’s motion blur and particle effects to capture the kinetic energy of his high-speed action. Incorporate a mix of urban grunge and vibrant comic book aesthetics to enhance the intensity of the scene.
