Given: The DCU is too white-male-centric.
Given: There are only so many good names/costumes/raisons d'etre.
Obvious Solution: Any property from second-tier on down is subject to being killed off and rebooted as a non-white/woman/both.
Okay, I get that. I like that blacks and women can be superheroes without being "Black This-or-That" or "She-Something".
Corollary Solution: Any property -- any property -- is subject to acquiring a partner/kid sidekick.
I even get that. I have to admit I wondered what kind of powder is in the sugar bowls in the DC breakroom when I saw Miss Martian, but dang it, she grows on me. (If only her breasts didn't grow and shrink from page to page, but then she IS a shape-changer.)
Here's what I don't get.
Did nobody at DC actually read Kingdom Come before they decided to make it happen? It was a dystopia. It was a nightmare. I always interpreted it as a commentary on Marvel Earth as well, since Stan Lee really wrote (heh) the book on leaving the villains out of the story completely and having alleged heroes whomp on each other for whole issues at a time. (Maybe Civil War was inevitable, at that.)
Specifically, it was hell on earth for non-metas, who appear to be drifting out of comics, even as supporting characters.
