I'm not a huge Superman fan, but these ideas just popped into my head and I had to ask somebody, so I'll ask you guys!
I'm wondering what the stories would be like if he had been brought up by the families of the other heroes.
What if Superman had...
...landed in the Wayne's back yard? Imagine Batman and Superman fighting crime together from their youth, what a menacing duo! Beats Robin anyway. How would that change Batsy's and Supermans attitudes?
...landed in the ocean and was found by the Atlantians? How would Superman act if he had spend his life under the rule of the magical Atlantis royalty, Aquaman himself? Would his powers be weakness by the lack of sunlight beneath the waves or would the pressure and constant swimming strengthen him?
...landed in the throne-room of the savage Amazons? How would the Amazons react to a man that could kick their asses? Imagine a hardened, battle trained Superman cutting off heads! Would Wonderwoman have a arranged marriage with ol' Supes, would their kids be the greatest warriors on Earth?
