In news broken on Bleedingcool, the upcoming Flashpoint Event might not be as self contained as say the Sinestro Corps War was. In a somewhat surprising move, there has been the implication that the Event will be line wide, much like Blackest Night on steroids. It appears the entire DCU might have their books canceled for a time and replaced with mini-series’ that fit into the Flashpoint reality.
While bleedingcool has offered up some titles they think might fit well in this universe, I’ll suggest a couple more: Booster/Beetle (like Superman/Batman, natch) and Tween Titans.
