“Batman v. Superman,” which is regrettably not a landmark Supreme Court decision but rather the hot movie ticket of the weekend, is the first major team-up in DC Comics’ foray into interlocking live-action movie universes. We’ve got the big three heavy hitters front and center — Batman, Superman and Wonder Woman. In case the title isn’t enough to get the point across, this first installment involves Bats and Superman beating the hell out of each other.

This is peculiar, because Batman and Superman have by far the longest-running bromance in the history of DC Comics.

They’re the two big-ticket items of the DC universe, so naturally they interact on occasion. But the ties that bind them run far deeper than almost any other relationship either one shares: Batman has appeared alongside Kal-El more than any Robin, more than Alfred, more even than work-wife Commissioner Gordon. Superman has appeared alongside Bruce Wayne as often as he’s appeared with Lois Lane.

Make no mistake: The two loves in Supes’ life are a rock-star reporter and a guy who dresses up as a bat. Batman has his assortment of young wards, to be sure, but in the end the defining friendship of his life is with Superman.

Showing this involved pulling every single listed comic book appearance for Bruce Wayne and Kal-El across four unique universes listed in the DC Comics Wikia catalog, and then pulling every character who appeared in each of those.

At first I was expecting some sturdy competition for who was more independent. Batman seems to be a guy who does his own thing a lot; maybe that makes Superman the one in the relationship with a really one-sided text message history. Surprisingly not the case!

Or maybe Superman is social enough that he’s the one with Batman as his fourth or fifth groomsman. He has a friend whose entire shtick is that he’s “Superman’s Pal Jimmy Olsen,” after all. But it turns out that Superman is all about his gal and Batman:

Batman hangs out with Superman slightly more than he hangs out with the longest-running Robin, Dick Grayson. Taking the Robins as a whole would put them ahead of Supes, but that’s cheating. It’s similar with Superman. Lois Lane edges out Bats by 29 appearances out of nearly 2,000. Only around a fifth of Batman’s and Superman’s joint appearances were linked to the Justice League or the Justice Society of America, which means they do hang out extracurricularly.

About a fifth of Batman’s and a quarter of Superman’s appearances also involve Wonder Woman. This is most likely due to all of their longtime memberships in various Justice-related organizations, but still there are extracurricular team-ups.

A few other observations:

That makes Diana of Themyscira a bigger person in Superman’s life than alleged ”pal” Jimmy Olsen, who I assume is the most emotionally and existentially devastated by these findings.

Superman hangs out with his parents in about 7 percent of comic books. Batman, eh, not so much.

Green Arrow gets around far more than I would have imagined. Ditto for the assorted Flashes and Green Lanterns

Aquaman, despite generations in comics, gets around approximately as much as I expected him to. Aquaman gets “new phone, who this” approximately once a month. He is on nobody’s Friends & Family plan. Still, by virtue of his larger league memberships, he seems to have appeared in about as many Batman comics as The Joker. He gets a participation trophy.

Now clearly, number of appearances is not always an indicator of close friendship. Just because they appeared together in a comic doesn’t necessarily mean they were allies, indeed, throughout their immense history, Superman and Batman have often been at crosspurposes. This appears to be where we find ourselves this weekend at the cinema.

In the end, however, Superman and Batman will work things out. I mean, they were in a group called the “Super Friends.”
