The Death of Superman Xtinction Agenda

We wanted to tell the best possible story we could. Nothing more. Kids those days, they didn't get what the Big Guy stood for, you know? They thought he was all gee shucks and apple pie, flying around saving kittens from trees. So we thought we'd shake it up a little, show them his heart pumped blood just the same as you and me. But to do that we needed a memorable villain, right? Something original and not like anything else Superman had ever faced before!
