Superhero standing on coral above a surreal underwater city

A surreal underwater cityscape with a majestic Superman standing atop a coral reef, his iconic blue and red suit glistening with an otherworldly sheen as he gazes out at the horizon. In the distance, a diminutive mermaid version of Ariel from Disney's The Little Mermaid, sits atop a rocky outcropping, her long golden locks flowing in the ocean currents, a look of wonder on her face as she beholds the Last Son of Krypton.
