Post-Zero Hour R.J. Brande was to be J’onn J’onzz.

KC Carlson, Legion editor, explain the RJ/J’onn connection:

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.

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 Bouncing Boy and Duo Damsel’s wedding LONG before we ever got close to the book.)

Dork Note: Where's J’onn J’onzz.?
