My favorite Geoff John Superman stories are in his new52 run, which compromised Superman (2011-2016) #32-#39, collected as Superman: The Men of Tomorrow (2016).
Though it wasn't the best run the world has seen, some cool moments include (I think, anyway, some of these may be right before or after his run):
- Clark, who was closer in age to Jim Olson in the New52 and was at times his roommate, revealed his secret identity to Jimmy before anyone else.
- Having lost his powers for 24 hours due to use of the solar flare, Superman at one point stands between a gunman and his intended victim and persuades the gunman to give up without a shot knowing that a single bullet would have killed him.
- Testing out his new solarflare power leaves Clark powerless and naked at a different point around the globe every test, which means Batman has to fly all over the place picking him up in the Batcopter. Batman is as hilariously annoyed as one might expect.
- Without his powers due to the use of the solarflare, Clark is taken out for a night on the town by the rest of the Justice League in their civilian guises. This is the first time alcohol has the ability to effect him, so he gets very drunk, which is also hilarious. I also have to say that, in retrospect, this has an almost Last Super character to it, as that group of people would never gather together again in a friendly setting in Superman or Action Comics.
- Also notable are I think the first appearances of "Mr. Oz" and Ulysses, the first of whom plays a big role in Rebirth and beyond and the latter of whom Reborn made a point of showing in the merged Superman's revised past as though they planned to come back to him, although I don't think they ever did. The asterisk on both of them is that Superman continuity drastically changed after the New52, so if it were ever picked up again in an Earth 52 (See Doomsday Clock) book, they don't necessarily have to stick to Mr. Oz being Jor-El (A Rebirth era reveal that may not have been originally intended) or Ulysses, well, okay, they didn't really do anything with him that a new book could contradict.
In fact, the Rebirth Jor-El makes no sense. First he's an evil villain who haunts Superman and ignites death on a massive scale around the globe. Then Lois and Clark give him permission to take their son on summer vacation unsupervised. Remember back in the New52 when Mr. Oz could have been Ozymandias, a giant squid in disguise, or literally anyone else?
I'm a little bitter about them abandoning the New52 Superman. Does it show?
