So there was a theory for a while that a kid wearing a Iron Man mask who stands up to one of the hammer bots was actually Peter Parker. Which was a fun theory since the Stark Expo took place in Queens but I did not think much of it at the time.
Fast forward to now and Tom Holland in a interview confirmed that it was in fact Peter Parker.
Heres a bit form the article:
“It is Peter Parker,” Spider-Man: Homecoming star Tom Holland told The Huffington Post.
“I can confirm that as of today,” Holland continued. “I literally had a conversation with [Marvel Studios president] Kevin Feige only 20 minutes ago. Maybe I’ve just done a big, old spoiler, but it’s out there now. It’s cool. I like the idea that Peter Parker has been in the universe since the beginning.”
If you want to read more its up on I09.
Well the story got updated with some new info that makes it less confirmed. here's the new Tom Holland quote:
It’s funny, I literally had a conversation with Kevin like 20 minutes before [The Huffington Post] interview and he didn’t confirm it, I took it upon myself just because I thought it would be a good story and it’s exploded.
There was a interview with Kevin Feige that confirmed the exitance of a other big Spiderman Character in the MCU but since the interview refers to something that happens in homecoming I will not talk about who it is. If you do wanna know and spoil yourself on a easter egg in the movie I09 once again got you covered.
