Okay, so before I begin, let me start out by saying that this is my first article on here so please be nice in the comments. I'd also like to point out that there are mild spoilers for Thor, Guardians of the Galaxy, Thor 2: The Dark World, Captain America: The First Avenger, Captain America: The Winter Soldier Avengers Age of Ultron. Also, there are possible(?) spoilers for Doctor Strange and Black Panther.
Now for the fun part.
I'm assuming that we all know about the Infinty stones and gauntlet, so I'm not going to go over that. However, I am going to go over where and what the infinity stones are in the MCU
The first Infinty stone we got to see on screen was the space stone in the credit scene of Thor back in May of 2011. We found out two months later in Captain America that the stone (not yet known as the space stone) was called the tesseract, and not only did it have great power, but it also had the ability to transport things and people across the galaxy (I might cover more on this in a future article). After being lost for numerous years, S.H.E.I.L.D. found the tesseract and began experimenting on it to see its full potential. After Loki used the tesseract's ability to transport and brought the Chitari to Earth, the tesseract was sent to Asgaard to be protected in Odin's treasure room, and that is where it is now.
The second Infinty stone we were introduced to was the Mind stone in The Avengers back in 2012. The actual stone was inside of Loki's scepter, and, again, we didn't figure out that the scepter's gem had an infinity stone in it until a little later. After the events of The Avengers, S.H.E.I.L.D. took posession of the scepter. However, after the fall of S.H.E.I.L.D. in Captain America: The Winter Soldier, Baron Von Strucker and Hydra took control of the scepter. After the Avengers won the little back and forth that they all had with Ultron for the scepter and eventually the mind stone in Avengers: Age of Ultron, which was given to The Vision, and that is where the mind stone currently is.
The third Infinity stone we were introduced to was the Reality stone. This stone came in the form of the aether from Thor: The Dark World. And as we all saw in the mid-credits scene of Thor: The Dark World, the aether was taken to The Collecter's collection. However, when the collection blew up in Guardians of the Galaxy, the aether could very well have left the collection and could be amlessly floating around in space right now or doing anything really, we honestly don't know.
And speaking of Guardians of the Galaxy, we have come to our fourth and final infinity stone found in the MCU so far, the power stone. This was basically the whole plot of the Guardians of the Galaxy, so, if you haven't seen that, then all I can say is that its in the care of Nova Core.
So now, we still have two stones unaccounted for, but I'm assuming that the soul stone will come up in Doctor Strange somewhere, and the time stone will most likely show up in either the Infinity Wars' first movie or in Black Panther somewhere. But now, here is my theory: there are certain characters in the MCU that will be the keys to defeating Thanos in Infinty Wars.
Which characters you ask? Well, here is our "dream team" of Avengers/superheroes. The first person on the team would be....
You may think, "doesn't Thanos have to get all of the Infinity Stones in the Gauntlet to get full power?" And yes, The Vision does have an Infinity Stone in him. However we know for a fact that there are two Infinity Gauntlets in the MCU, a left and right handed glove. Why would you create two gauntlets if they can't both be filled at the same time? And the answer is you don't so there are most likely two of each Infinity Stone in the universe, but I'll explain that in another article. So that's how the vision could fight back. And then the next member....
Iron Man basically recreated the tesseract with his second arc reactor. If you'll notice in the above picture, Tony based his second arc reactor off of his dad's notes on the tesseract. This is one of the reasons I think there are two stones, man made or otherwise. The next Avenger I think would have to be....
If you look at Scarlet Witch's hands when she uses her powers, I personally think it looks like the aether. Also, she changes the reality of the person's mind, just as the aether/reality stone does. Coincidence? I think not! My next Avenger would be....
Doctor Strange is the Sorcerer Supreme and we will most likely have our intro diction to the soul stone in his solo film. If this is so, I believe Doctor Strange would be a valuable asset to this "dream team". Our next Avenger is....
Black Panther is the hero of an ancient society in Africa. Something has got to have kept the people in his society young(?) for as long as it has, and I beleive that that thing is the time stone. And being the hero of the society, he most likely would have been able to or taught to handle this precious artifact, making him also a vital asset to the team. And the final Avenger I'd like to add to this team is....
Peter Quill has already proven that he is able to hold an Infinty stone. The mother flipping power stone for crying out loud! Nuff sed.
I would also like to point out that there are two other people I would be willing to add to the mix. Captain Marvell seems like the only person in the MCU (besides maybe Peter quill) powerful enough, and smart enough to wield the power gauntlet, which would explain why her movie comes before the second part of Infinty War but after the first movie. Also, we know Captan America can block blasts from the space stone with his sheild, so why wouldn't he be able to block blasts from other things? Also, if the shield breaks, we could get a new one made from another planets strongest material. Also, who wouldn't want a scene where some wants one of the captains' attentions and they say, "Cap!" And both of them respond?
I know this was a long article but thanks for staying to the end. Please leave a comment below about what you thought about my theory, but please be nice, as this is my first article. Thanks!
