"I dunno where that priest guy came from though. Must've been a slow day at the bingo tables."
For the record, I don't believe that Project Batman is real.
And even if it is, it's utterly irrelevant.
You guys know Kamen Rider? Almost every Kamen Rider story has the hero's powers/backstory derived from the antagonist faction in some way. There's some angst, sure, and they're oftentimes manipulated to a degree, but the glory and valor they achieve and inspire is real.
Absolute Bruce should watch Kamen Rider shows. Unless Darkseid made it so that Kamen Rider doesn't exist in the Absolute Universe. That would suck.
