They're all okay, except Superman's hair. That hair looks silly.
So... is this supposed to be Clark, Diana, Bruce, etc. just set in the year 3000? Or is it actually the future of the New 52 universe and these characters are descendants/replacements? I need details!
Also, when I think about future-DC, I like to think about the Batman of the Future/Batman Beyond time period. That feels futuristic enough.
Going one thousand years into the future seems like way too much. Surely technology would have advanced so much that super heroes just wouldn't function the same, but looking at those images seems to indicate the Justice League wouldn't be all that different.
...I'm probably putting way too much thought into this. Like I said, I need details!
