If you've picked up any of the New 52 DC titles then you'll have seen a purple woman, in a cloak, wandering around in the background. She's been in every single issue so far, being ominous and watchful. In case you haven't noticed her little cameos, then perhaps you'll know her from this more blatant appearance at the end of Flashpoint #5.
Her name is Reverta. Why is that her name? Because I've just called her that. She's the reset button in case this 52 thing doesn't work for DC and they need to go back to their original timeline. Reverta comes from the previous DC Universe, but has somehow crossed in to the new one somehow. She was in Action Comics, sat on a bus. She was also in Animal Man, wandering around in the background. Sometimes she is drawn into the panel, and sometimes she is very blatantly cut-and-paste into place (hello, Justice League International!)
What you have to remember is that her name is REVERTA. Because I've decided that's what her name should be, and I've also decided that it's about time Comics Vanguard made an everlasting mark upon the DC Universe.
Reverta. Look out for her. She'll be in every DC issue you buy this month. And then probably return in a year for some kind of Geoff Johns event storyline.
Or maybe she's a sign that Grant Morrison's long-rumoured "Multiversity" project is finally about to happen?
She's called Reverta.
