Riiiiiight, so you guys will have to put up with me freaking out about Spider-Man in the MCU and all the dynamics that creates between the characters, and I’m actually super surprised I haven’t seen anyone else go into this because it’s so interesting.
So we know Peter has been swingin’ around New York for a while before he meets the Avengers for the first time. He’s mostly going after muggers and car thieves so that’s not really a surprise, but as soon as the media catches wind of him, the Avengers are gonna get curious (I mean, a powered person in their territory isn’t something they can leave alone, and SHIELD is going to want to Index him, and basically Peter won’t be able to stay in the shadows for long).
Even if he’s not tracked down and interrogated by either of the groups, Peter won’t be keeping his distance. Sure, he might try, but if an Avengers-worthy fight is going down in NYC, he’s going to step in, no matter how over his head he may be. This means interacting with Earth’s Mightiest Heroes, who will pick up that Pete is pretty young, even if they don’t get how young (He’s about 15, but maybe tall for his age, maybe he tries to disguise his voice
but how well do you really think he could pull that off?, and the biggest thing is that they wouldn’t expect a high schooler to be fighting crime, so most of them wont see it).
But what I’m really excited for if after Peter reveals his identity to them. (Assuming he does, which is likely. It’s possible the Avengers could try to learn it on their own, but without SHIELD making them, I think they would step back once they’re sure Spider-Man’s on their side.) Peter’s age would change everything between him and the team.
Let’s start with Tony and Bruce. Maybe they figure out Spider-Man is a smart cookie when he helps them during a fight or whatever. Maybe they want to introduce him into their Science Bros Club. But when they learn that Peter’s just a kid, that could change. Tony may decide he’s Pete’s new mentor (”Shut up, Spangles, this is a great idea.”) but Bruce, being the more sensible one, might recognize that what they do is dangerous, that he’s dangerous, no matter how in control of the Other Guy he is, and think that Peter would be safer if he stayed out of the labs. (And Peter would be crushed by this, because Stark and Banner are pretty much his idols and, wow, that would suck.)
I really have no idea how Thor would react, but I think he would be Peter’s strongest supporter. Given an Asgardian’s life span, all Midgardians would seem young to him, and ten, twenty years would seem like no difference at all. As long as Spider-Man was a fine warrior, Thor would love to fight alongside him.
I’m also not sure about Natasha. She started young too, so maybe she would give Peter a chance, or maybe she would want him to get out as quickly as possible because she knows what fighting does to a kid. But he’s not giving up, and she knows that, so she would try and make sure he doesn’t get himself killed. Maybe she’d give him a bit of training or a couple lessons in strategy. (Also, their fighting styles are pretty similar and I’d love to see them spar. I think Peter’s Spidey-Sense might help him last a little longer than most people and it’d be so fun to watch.)
Clint. Before learning about his family, I would have thought Clint would try to convince the others to give Pete a shot. But Clint’s a dad, and Peter’s only a few years older than Cooper, and it would kill him to see a kid on the battlefield when he knows that it could be his own son. Clint would be super overprotective whenever Spidey and the Avengers fought together, and he would put himself in harm’s way all the goddamned time even though Peter is capable of handling himself, thank you very much. (And if we don’t get to see Clint using his “dad voice” with Peter at least once, I am going to be very disappointed.)
Now, Steve has seen kids in battle before. In WWII, there were plenty of kids Peter’s age lying to get enlisted and I’m sure Steve’s seen them, hell, maybe he’s even led them. He’s seen kids fight, and he’s seen them die, and he would do everything he could to stop that from happening to Peter. At first he would try to convince him to hang up his suit and wait until he was older, but Steve would see that Peter is a lot like him, and wont stand to see others being hurt when he can do something to help. So Cap would offer help whenever it was needed, and he’d try to teach the kid a thing or two, and he’d just try to make sure he’s not sending the kid out to die.
I’m really excited to see how this plays out.
