This is a panel from Dark Reign: Fantastic Four #2.
In Marvel’s main continuity, on Earth Prime, Tony Stark aka Iron Man and Steve Rogers aka Captain America (BOTH DUDES—keep this in mind, this information is important) fell on opposite sides of a debate during Marvel’s CIVIL WAR event. Tony Stark was pro-registration after the Superhuman Registration Act was passed—which demanded superheroes reveal all of their personal information and give up their rights to privacy, concede to being labeled a “human weapon of mass destruction,” and undergo proper training determined by the US government—and Steve Rogers was anti-registration. There are a bunch of reasons why the both of them sided the way they did, but the whole thing was a big mess and in the end, Steve ended up dying.
On Earth 3490, Tony Stark was born a woman—Natasha Stark—and instead of the big mess and the fighting and the death with the whole civil war thing, she and Steve just got married and boned a lot.
NOW. LOOK BACK AT THAT PANEL UP THERE. Reed Richards is looking through some big machine he made or something to see where he went wrong with the Superhuman Registration Act and is looking at alternate universes to see what resulted from the same actions and determine what ended in conflict and what ended peacefully.
“THE 47TH PEACEFUL MODEL EXAMINED BENEFITED PRIMARILY FROM THE ROMANTIC INVOLVEMENT OF CAPTAIN AMERICA, STEVE ROGERS, AND THE IRON WOMAN, NATASHA STARK.”
IN SUMMARY: IF TONY STARK AND STEVE ROGERS HAD GOTTEN MARRIED AND FUCKED THE CRAP OUT OF EACH OTHER ON EARTH PRIME, THE WAR OVER SUPERHUMAN REGISTRATION WOULD NOT HAVE HAPPENED. This is canon. The relationship between them is so passionate, it saved another Earth from a civil war between superhumans because they were allowed to act on their passion. Steve/Tony is canon, in at least one universe.
I’m just saying.
