The background should combine iconic aspects from Superman's Metropolis and the vibrant, playful environment of Elastigirl’s world, creating a seamless integration of both settings. Emphasize the superheroic demeanor, capturing strength and agility within the design while maintaining a bright, dynamic atmosphere.
