>>120535659>Kryptonians were xenophobic assholes who tried to take over the galaxy until being pushed back to Krypton so they could self-isolate and feel superior No, the empire was only the case in the post-Infinite Crisis Busiek run—and this was only a brief period in Kryptonian history, and they stopped conquering because the Science Guild overtook the Military Guild, not due to any xenophobia; check the storyline “The Third Kryptonian” for further details—not the New 52 or in most other portrayals of Kryptonians. New 52 Kryptonians as created by Morrison were an intelligent, moral race that mostly kept to themselves, as is the case with most versions of Krypton.
But to answer the OP, I think this was just a case of throwing an idea out there for other writers to build on. I don’t think there was a plan to it.
