Now that we've had a chance for this to settle in, let's talk about how Spider-Man joining the MCU affects the future of the films and how he could be introduced in the upcoming Phase Three.
Also, be warned that this article will include potential spoilers for upcoming films. Though it's all speculation, the events explained here have taken place already so technically, they're not really spoilers.
This one's an obvious mention. For those of you who are unaware, in the comic books, Spider-Man played a pretty big role in the Civil War arc (2006).
Civil War began when the Superhuman Registration Act (SHRA) was enacted, which forced superheroes to register themselves as "living weapons of mass destruction" - Woah.
From this there was a divide, between the heroes who were for and against the SHRA. After a vehement battle between the two sides, the result was the death of one Steve Rogers - Captain America.
Steve Rogers represented the side who were against the SHRA, whilst on the other side Tony Stark, AKA Iron Man was pro-SHRA.
Still with me? Okay. I've skipped a bunch of stuff here, but it's important to know that Spider-Man - after being talked to by Tony Stark - had joined him and the rest of the heroes who were pro-SHRA.
During a press conference, Iron Man introduced Spider-Man to the podium which led to Spidey (after explaining how until now he'd kept his identity a secret but thought what Captain America was doing wasn't right) unmasking.
How Will This Fit Within the MCU?
Well, at the moment anything is just speculation. We know that it'll definitely be Peter Parker and NOT Miles Morales as many of us thought it would be.
When will he show up? We can hope he shows up at the post credits of Age of Ultron, but again, nothing is set in stone here.
If not, then there's Captain America 3: Civil War. Here's where they'll really need to utilise him. He played a pretty pivotal role in the comics, so it only makes sense to have him play a relatively big role in this.
So at this point, we're playing the waiting game. And it isn't fun. But it's an exciting time to be a fan, that's for sure.
Avengers: Age of Ultron has its general release May 1.
