The Clown Prince of Crime
Super Freak
Pete always was a fan of the Avengers, both in 616 and in 1610. He always wanted to sit in the Big Boys table. he may have debuted a bit earlier (roughly a year), but he was always younger than all of them, so it makes sense, it's nothing weird or forced. Spider-Man was always the young guy in the wide Marvel-line.
Yeah, I'm sure it makes sense, but for me personally, I wasn't an Avengers fan growing up.
I mainly focused on the X Men and Spider-Man comics and cartoons, so the Avengers really weren't a factor, except for the occasional cameo.
I knew about Iron Man, Thor...etc...but to me they were just B List heroes, and Spider-Man was somewhat isolated from the rest of the MU in my experience, even if that wasn't the case, so to me he wasn't just a young kid or a fan, he was Spider-MAN and Marvel's top hero.
It's just weird that I'm now older than Spider-Man ever was, and on top of that, he's like an Avengers fanboy
