DC just announced Dawn of the DCU, a new editorial era for its comics starting in 2023 after the conclusion of Dark Crisis on Infinite Earths. The Justice League has been restored, the Infinite Earths are back, and the Omniverse has been reshaped – but what exactly does that mean?
Although Dark Crisis on Infinite Earths doesn't end until issue #7 releases in December, making it impossible for us to fully understand what's to come, the variant covers released so far by DC may reveal something unexpected and now seemingly significant...
The return of the Batman-Superman-Green Lantern fusion who appeared in Batman/Superman: World's Finest #4 (set in the DCU's past), written by Mark Waid, drawn by Dan Mora, colored by Tamra Bonvillain, and lettered by Aditya Bidikar.
While it's possible these Dark Crisis variants drawn by Felipe Massafera and Tony Daniel, seen here, don't indicate anything for Dawn of the DCU, there are two of them, so it seems likely the character (who still hasn't been named, though we vote for Green SuperBat) will return in the present-day timeline. In Daniel's cover, seen above, he's explicitly shown fighting Deathstroke, whose Dark Army battles the remaining heroes on Earth-0/Prime in Dark Crisis on Infinite Earths #7.
DC is referring to this battle as the beginning of 'the final war,' although it also says the Great Darkness has been defeated. Does Green SuperBat have something to do with it all?
In World's Finest #4, the Devil Nezha – who's currently the Big Bad Evil Guy in Batman vs. Robin – possesses Hal Jordan, AKA Green Lantern. To defeat their teammate and friend, Superman and Batman have to find a way to remove Hal's ring, which is the source of his power.
Together, they concentrate hard enough
