10 Shocking (But Believable) Spider-Man: Homecoming Theories
9. Iron Man Won't Be The Only Avenger Involved
The Theory
According to several rumours, Tony Stark won't be the only former Avenger to make an appearance in Spider-Man: Homecoming. He could be joined by Captain America (or Nomad if you're choosing to believe that rumour), or Black Widow or Nick Fury or all three in some combination.
It's just a shame nobody seems to be hyping a possible appearance by Ant-Man, given how much chemistry the two insect-like heroes had in Civil War. Anyway...
Why It's Believable
If you choose to accept that Homecoming is going to be a Post-Civil War movie as much as it is a Spider-Man stand-alone, the presence of Captain America in particular makes sense. He would be duty-bound to try and interfere if he believes that Tony Stark is looking to indoctrinate Spidey into his ideology. He knows how potentially powerful the wall-crawler is, and given the way the Civil War comic played out, it would make absolute sense that he would be the object of a superhero tug-of-war for power.
It's probably more likely to be a mid-credits scene rather than a big part of the main film, but that is exactly as it should be to set up a more intriguing foundation for Spidey's appearance in Infinity War.
