Suppose Krypton had exploded just a bit later, and Jor-El and Lara had sent off their little boy and his baby brother. Or, suppose Kal had been born as one of a set of twins!
Would Kal still be the reporter named Clark Kent, and his brother be Superman, or would it be the other way around?
How would Clark feel seeing Lois swoon over Superman, this time with the knowledge that Superman is truly a different person?
This idea has the potential for comedy or tragedy, especially if they are twins who alternate being Superman.
Better still, what if the brother is in love with Lucy? Or someone else entirely?
This could also put a different spin on episodes such as Vatman!
Well, what do you think?<g>
