A Little Piece of Kripton (One Piece x Superman)

Silvers Rayleigh discovered an alien baby while vacationing on an uninhabited island and decided to adopt the child. The sorrow he felt after losing Gol D. Roger gradually began to give way to a renewed sense of hope.

So far, the young man has successfully avoided the attention of the World Government. But what will happen if he decides to follow in the footsteps of the Straw Hat Pirates, just as his father wishes?

In this story Kal-El not really kind heart and superhero-ish. He understands sympathy and the moral distinction between right and wrong, but he doesn’t see saving others as his responsibility. i don't plan to write romance, but if I do this story still going to be PG-13

Thanks to GPT for helping me. This story is not perfect but I tried as English is not my first language.
