Iron Man 4 Wishlist: 10 Things Fans Demand
2. Spider-Man (Or The Iron Spider)
With Tony Stark appearing in Spider-Man: Homecoming and apparently taking on the role as Peter Parker's mentor, there's no reason why the relationship shouldn't continue into Iron Man 4. And if that could include the introduction of the Iron Spider suit, even better.
Will It Happen?
It really all depends on where Marvel go with the Infinity War movies: there's every chance that the post-Civil War fracture in Stark and Parker's relationship in the comics will play out in Homecoming and beyond, which would render any Iron Spider possibilities impossible.
And of course, there's every chance that the suit Parker is wearing in Homecoming is the MCU's version of the Iron Spider - since it's already been hinted that it features augmentations Parker isn't entirely aware of. Which means doubling down on an even more augmented suit might be overkill.
Still, it's a nice idea.
