So, apparently, between Action Comics and maybe Superman trade volumes, there was some story involving Mr. Mxyzptlk and the other Clark Kent that, I think, merged the pre- and post-Flashpoint Supermans and Lois Lanes into one being each.
Regardless, here’s the next official Action Comics volume, subtitled The New World.
So, after the two Supermans (Supermen?) merged or whatever, we start with Superman going off to the Fortress of Solitude to go over his history so the reader knows what the merged Superman has as his backstory. While that’s going on, the Cyborg Superman is putting together the most recent version of the Superman Revenge Squad. Who’s on it? Metallo, Mongol, some telepath named Blanque, the Eradicator, and eventually General Zod. Cyborg Superman promised something for each of them beyond simply killing Superman, but he may have problems of his own since Zod isn’t the patient sort to follow another man’s plan.
Writer Dan Jurgens actually had the title live up to its name for this one: there sure is a lot of action on display here, especially as Superman himself isn’t short of allies beyond Lois Lane and their son Superboy. It’s a huge free-for-all, and while the volume ends with more story for later, this one was exciting enough for now. That’s more or less how I have felt about most of Jurgen’s Rebirth Superman work: he’s setting things up for the future, but at least giving us an exciting story along the way, and this one does feature a number of Superman allies at various points including Krypto, Supergirl, the temporarily heroic Lex Luthor, Superwoman, Steel, and the Chinese Super-Man. For all that, let’s say 8.5 out of 10 mystery voices.
