I don’t work for a comics shop and I only have a finite amount of spending cash per week, so I don’t claim to understand the apparently self-perpetuating Infinite Identity Countdown to World War 52 One Crisis Later that has hopelessly ensnarled every single DC title. However, I did notice that Earth-3 is evidently back in play. These days it seems that the Crime Syndicate’s home dimension (or, no; it’s the Crime Society, isn’t it? Wow, that’s not confusing at all. Anyway, Earth-3) features a Joker-analogue, the Jokester, and (logically enough) he is a vigilante hero there. This piqued my interest because offhand I don’t recall any previous Joker-incarnation who wasn’t a criminal sociopath to some degree. Given that every other universe familiar with the Joker is likely to regard him unkindly, I would hazard a guess that the Jokester isn’t likely to survive for very long in the current state of reality flux. At the very least he’s eventually going to run up against his prototype, and that surely won’t end well for him.
All of this is by way of introduction to my main point, however, which is this: it occurs to me that Earth-1’s Superman might well share the Jokester’s rather awkward situation. Most of the DC Earths boast a Superman-analogue of one sort or another, and the majority come across as either actively evil or else so thunderously incompetent that they might as well be. Most of these other Earths would probably consider the existence of a decent, genuinely heroic Superman as Earth-1’s signature oddity.
So far, the current DC multiverse has provided us with:
Earth-2: Golden Age Superman (easily manipulated into starting a war)
Earth-3: Crime Society Ultraman (evil)
Earth-4: Captain Atom (evil)
Earth-9: Tangent Superman (to be featured in the upcoming book Superman’s Reign. Yes, that doesn’t sound evil at all)
Earth-10: Nazi Superman (possibly evil)
Earth-15: Super-Zod (apparently not evil, but unable to save his Utopian reality from destruction, so chalk him up under “incompetent”)
Earth-22: Kingdom Come Superman (incompetent)
Earth-30: Commie Superman (establishes global totalitarian Stalinist regime)
Earth-31: probably Frank Miller’s Superman (incompetent)
Earth-40: Golden Age Super-Zod (evil)
Earth-50: several analogues, some of which are apparently not walking disasters; though the closest parallel seems to be Planetary Clark Kent (incompetent)
Antimatter Universe: THREE! Crime Syndicate Ultraman (evil), Cyborg Superman (evil), Superboy-Prime (evil)
That be a lot of evil Supermans. And even the non-evil ones often manage to facilitate evil through their inaction, slow-wittedness and/or easily manipulated nature. Frankly, the only thing keeping evil Supermen from totally dominating the multiverse is the fact that they are very nearly as incompetent as the non-evil ones.
The bottom line is this: Earth-1’s Superman is the anomaly. He’s practically the only one that a person in need can look to for reliable help. Objectively, it appears that Lex Luthor is correct in his overall assessment of Superman. When one considers the total multiverse, the odds seem to lean toward any given Earth’s incarnation of Superman being evil, or at the very least screwing up royally at the worst possible time. If Lex ever suspects himself of being the bad guy, all he has to do is look at the alternate realities that each new Crisis reveals. The transparently evil Sinestro Corps from the Antimatter Universe of Evil boasts two Supermen in its roster; how many Luthors made the cut?
Batman knows the score too. There’s a reason why the Earth-1 Batman is so twitchy; why he seems to spend more time plotting the deaths of his allies than fighting villains. Every day he’s waiting for the other shoe to drop-- waiting for his Earth’s Superman to go the way of all the rest. You never see any viruses specifically tailored to kill Luthor in the Batcave. Even Batman’s evil counterpart Owlman has a healthier relationship with Ultraman, because Owlman knows that Ultraman is evil already.
Superman probably freaks Batman out for another reason: Earth-1’s Superman stands out among his other incarnations in that he is uniquely decent and effective. But if Batman has spent any time learning about those other Earths, he has surely noticed one other constant: the Batmen of other Earths are all surprisingly decent and effective. (The Crime Syndicate’s Owlman might be exempt from this effect because he’s from the Mirror Universe, and possibly also because he’s not truly a version of Bruce Wayne, but his brother.)
Batman’s keen mind will have no doubt picked up on this pattern, and so he wonders… “If Superman is a malignant spaz on every other Earth, but a genuine hero on this one… and the Batman is a stalwart, moral character on every other Earth… what does that suggest about me? Am I the one that’s the idiot? Dear god, my arch-enemy is a clown! And he won’t even stay locked up! What the hell have I been doing with my life?” Fortunately he probably knows some Tibetan mental discipline to keep himself from losing too much sleep over it.
In summary: if you suddenly find yourself transported into a horribly dangerous situation on a random Earth of the DC multiverse, think twice before calling your neighborhood Superman for help. There’s about a 1-in-52 chance that he won’t make things even worse.
