I think it is valid since they are married

Or maybe it would have vulnerability to both.

That would be one op hybrid

This technically has happened. Superman of Earth-32 is a hybrid of Superman and Martian Manhunter, and his only weakness (at least according to the wiki) is red sun radiation.

Don’t forget Miss Supermartian!

Well if you want to go even crazier how about a Kryptonian/Amazon/Martian/Thanagarian/Tamaranean hybrid

Forward that to Dabney Donovan. If anyone can do it, he can.

@Legionaire315 Five alien races? That's an odd number. What would his ancestry be like? Would the Kryptonian/Martian hybrid be his grandfather who married a daughter of Thanagar and Tamaran, and their son married an Amazon?

Hey, why don't we add an Atlantean to the hybrid. The Amazon can marry an Atlantean man. Wait, would an Amazonian hybrid automatically be a girl?

Oh I also forgot to include Atlantean
