We are quickly approaching the next installment in the MCU, Captain America: Civil War. There has been a lot of speculation about the story and how closely it will follow the comics, especially considering the effort Marvel put into get the rights to Spider-Man.
What we do know is that Civil War picks up where Avengers: Age of Ultron left off. Captain Rogers leads a new team of Avengers in their continued efforts to safeguard humanity. There is another international incident involving the Avengers results in collateral damage and afterwards political pressure mounts to install a system of accountability and a governing body to determine when to enlist the services of the team. This causes a fracture among the Avengers as they try to protect the world from a new and nefarious villain.
The fracture ultimately leads to a split in the team with heroes choosing sides. On the side that disagrees with the registration act is Captain America, Hakweye, Falcon, Scarlet Witch, Winter Solider and Ant Man. On the side opposing them is Iron Man, Vision, Spider-Man, Black Widow and War Machine.
For the most part this falls in line with the comics, most especially Cap, Stark and Spidey. Rumor has it there is a double agent in one of the groups. Assuming that is true (and I must remind everything all this is speculation at this point) many are guessing the ‘tratior’ to be Black Widow because of her ties to both Steve Rogers (Captain America) and Clint Barton (Hawkeye).
I however, have another guess. Spider-Man.
Remember when I said earlier that Marvel went through a good amount of effort to get the rights to the web head? That’s because he plays a very, very important role in the Civil War story line that ran through the comics. Part of the registration act is that heroes must reveal their identity. It’s not a problem for Iron Man and Cap as everyone already knows who they are (in the MCU that is), however that isn’t true for everyone. (Also keep in mind I havne’t seen Ant Man or Age of Ultron yet so this is subject to change. Bad Anthony.)
In the comics Spider-Man discovers that he has been duped somewhat by Tony Stark and decides to change sides, in the process he reveals his identify to the world.
That said, there is a lot of set up and some back story involved to get to that point. A lot for a two-hour movie. Not to mention the fact that even though everyone knows who Spider-Man is this is a new Spider-Man so take everything with a grain of salt.Source: Comicbook.com
