Marvel’s What If…? series is one of my personal favorites. Every issue is a crapshoot and you’re usually going to either find something entertainingly good or entertainingly bad. When the writers aren’t tripping over themselves to do stories where every hero dies because it’s so edgy, there are some cool, creative incidents in there. We’ve seen Richard Fisk become Daredevil, Flash Thompson become Scorpion, Sue Storm become Man-Thing, and Galactus become Elvis Presley. We’ve seen Norman Osborn conquer his demons, the Kingpin love Matt Murdock like a son, and Kraven the Hunter eat Spider-Man’s face. All good times.

With so many good ideas, it’s no surprise that Marvel has ended up incorporating some of them into regular or Ultimate continuity, whether accidental or not. They even created an entire segment of standalone long-running continuity out of the Spider-Girl issue. Now, a lot of these have become punchlines for years. Every now and then, someone will post a bunch of covers with issue titles that have come true in some fashion. “What If Spider-Man’s Clone Had Lived?” “What If the Hulk was a Barbarian?” “What If Spider-Man Didn’t Marry Mary Jane?” “What If the World Knew Daredevil was Blind?” Since those make this too easy, I’m going to exclude any instance that comes from the issue’s title spelling it out.
