Is this a sign of something in-universe, with Atrocitus and Roy Harper? Is it an Elseworlds tale with Hal and Ollie? Is it something that’s just so crazy it might work? ‘Rama readers, start your speculation.

It’s part of the series of homage covers using classic comics with modern takes that DC is doing for its 75th anniversary. My guess.

Robot 6 beat you to the punch, guys… It’s an alt-universe cover that will be featured in tonight’s season finale of (the excellent) Fringe. Looking forward to it! I hope John Noble will get an Emmy nod this year.
