BTW, did I ever tell you that, in the Legion reboot, our R.J. Brande was actually the Martian Manhunter? We waited too long to reveal it and then Dan Raspler (JLA editor) wouldn't let us do it because it might screw up J'onn.That would have put an interesting spin on events, no? I would have loved to see J'onn J'onzz alongside the teenagers from the future.
At this late date, I'm not sure if it was a good idea or not, but we did plant some clues. (And don't forget, he was at Garth and Imra's wedding LONG before we ever got close to the book.)
