We recently got an introduction to Captain Marvel, and people would argue that the movie could have been a little better, but no one would actually say that it was a bad outing. We got the gist of who Carol Danvers is and a glimpse of what she is actually capable of. So that really is enough if you think about it. Now, Captain Marvel will really be established as the strongest MCU hero there is. She will be really important for the future of the MCU, and that is why she is will be really crucial to the plot of Avengers: Endgame.
Kevin Feige has already confirmed her to be the face of the MCU along with Captain Marvel. He confirmed that she will be the one that takes the MCU forward along with Black Panther, Spider-Man & Doctor Strange. She will obviously be the leader of the new team, and to have a transition for that, Captain Marvel has to have a big role in Avengers: Endgame.
Here’s what Kevin Feige said about her future with regards to the MCU:
“When we found out that Brie Larson might be interested in joining our world, we had a number of meetings. She was a huge fan of the character in the comics. One of the highlights of my career at Marvel was introducing her at Comic-Con and having her come out on stage and stand there with literally almost everybody else from our movies. There she was at the forefront, and it was a great foreshadowing – not just for how audiences are going to embrace Brie as this character, but also for how Captain Marvel is about to take the lead and be at the forefront of the entire Cinematic Universe.”
So with Feige really gunning for Captain Marvel, you’d think that she would be really important to the MCU. Captain Marvel was a film with a lot of unexplored territory. We need more from the Kree and the Skrulls, but apart from them we actually need more exploration for Captain Marvel herself. Her origin was explored vaguely, and so were her powers.
Talking about her powers, they weren’t actually explained at all if you think about it. We were shown that she has Photon Blasts, superhuman strength, can defy gravity, fly in Space and go binary! But it may have been a deliberate move to not give us the full detour upon her power.
The creatives may have left some of the exploration to be done later on in the MCU as there’s still a lot of history left to be told. But the answer to why Captain Marvel would be so important to the plot of Endgame actually lies her origin. Carol got her powers through the explosion of a device capable of achieving hyper-speed in space, which was actually powered by the Tesseract. The explosion of the device caused its radiation to mix with Carol’s DNA. And she also has Kree blood coming from Yon Rogg, so a blend of all this makes her who she is.
But if you think about it, the core of her powers actually comes from the Tesseract, i.e. the Space Stone, and that’s what may come in really handy in Avengers: Endgame. As we saw in Infinity War, Scarlet Witch who got her powers from the Mind Stone was able to break through the molecular Integrity of the Mind Stone, i.e. she was able to destroy the Mind Stone because of her powers being similar.
So, what if Captain Marvel is needed to do the same? What if this is why Captain Marvel’s origin story was pushed in right before Endgame, just to explain this? Captain Marvel’s powers do come from the Tesseract, and just like Wanda was able to break through the Mind Stone, Captain Marvel could actually do the same to the Space Stone.
An attack from these two female heroes upon the two Infinity Stones, could destroy at least 2 of the stones, if not all 6 of them. People have suggested that the Infinity Stones must be terminated so the future of the MCU could start from a new leaf and not be dependent upon the Infinity Stones. Captain Marvel may be the means to that!
