From CBR: “Era-displaced comic book characters!! Imagine if the Superman from 1938 replaced 2012 Superman. Or 2012 Superman replacing 1938 Superman. Or 1939 Batman replacing 2012 Batman. Or 1955 Batman replacing 2012 Batman. Give us ideas for era-displaced comic book characters. What if 2010 Roy Harper replaced the Roy Harper in a 1966 Teen Titans story? What if 2012 Iron Man replaced the Iron Man from a 1963 Avengers comic? Or 1963 Iron Man replacing Iron Man in a 2012 Avengers comic? And so on and so forth!”
This is... JUST the way you know Charlie Brown will end up while hoping that he won't. His whole disappointing life in one panel. And so well executed too.
