Iron Man is Out of the SPIDER-MAN: HOMECOMING Sequel and a Different Marvel Superhero is In
Marvel and Sony are already planning their sequel to Spider-Man: Homecoming and Iron Man will not be returning. As you know, Iron Man plays a huge role in Spider-Man: Homecoming. He's been featured so heavily in the marketing of the film that fans joke that the Spider-Man movie is actually Iron Man 4.
Turns out, when the sequel rolls around, Iron Man won't be a part of it. But, according to THR's inside sources, there's a new "to-be-determined Marvel character" that will join Spider-Man on his next adventure. I have no idea who that would be.
I know it won't happen, but I'd love to see Spider-Man team up with Daredevil or Deadpool. It'd also be kind of fun to see him and The Hulk join forces, which seems more likely, but there are going to be 60 Marvel characters in Avengers: Infinity War and the character who joins Spider-Man could end up being any one of them.
Now that I think about it, The Hulk would actually be kinda great because I think Bruce Banner would make a great mentor for Peter Parker. They also have some great comic book story arcs together that Marvel could pull from. A movie featuring these two characters could be a blast!
As for why Iron Man won't be returning? I have a feeling that many of the core team members from the original Avengers roster won't be returning to the MCU after Infinity War. Like Kevin Feige said, that story arc is going to change everything.
