No harem pls + ther is no need to chose his girl from the usuel like natasha and emma and storm ... - First the story will collaps and you need more thinking to fixe it - second it will be very prodictable and very repetitive - third and more important it's boooring. Sooo Just add a girl of your own creation to the story and give her the power you like and the power it suits the plot . You can also think about the power that is passed down to his children with the kriptonian blood . Finally this is just an advises but i really hope you take it into consideration 😉
