I always have that same kind of doubt, if Sony had never let Disney use Spider-Man in Marvel, how would the world of Spider-Man be.
Like Tobey Maguire's Earth-96283 or Andrew Garfield's Earth-120703 where we only see mostly different types of superhumans appearing only in New York. Along with typical Spider-Man companies like Oscorp, the Daily Bugle, Quest Aerospace, etc.
And even today with Spider-Man being part of the Marvel universe, there are many theories about the world of Earth-96283 (Tobey Maguire) and Earth-120703 (Andrew Garfield) as to why the Avengers don't exist, or why Stark, Ironman, Hulk, Captain America, none of this is mentioned.
Some claim that on these worlds everything simply did not develop in the same way, which resulted in Stark, the Avengers and others never appearing.
In the case of Stark maybe he died or maybe nothing ever happened to cause him to become Ironman.
And with the Avengers a similar thing.
Now, others have even theorized that maybe in these worlds the Marvel characters never really existed, so it's all different.
In any case, I want to know what you think and how you think the world of Spiderman would develop without Marvel, either by eliminating the characters or making them become of no real importance even though they exist in the world.
