in a dark fantasy, 1980 movie, movie, photorealistic, a hyper-realistic full-body image of a 16-year-old boy in a post-apocalyptic world where only 'Gifted' children with elemental powers survive. His design should mix elements from ancient Atlantis and Mu civilizations with a sand planet and Zelda-like fantasy world. The boy’s attire should include modern practical features for swimming and retrieving artifacts from submerged ruins, as well as detailed ancient-style decorations. The hair should be uniquely styled, perhaps resembling a mix of natural and fantastical elements. The clothing should integrate both ancient mystique and contemporary functionality, including utility pouches and accessories suitable for exploration in a harsh, submerged environment.
