Avengers: Endgame Theory –
The release of Infinity War was something that shook the comic book movie industry to its core. It changed how we perceived these movies. We saw a definite paradigm shift in writing and movie making after the introduction of the Infinity War in the mix. It did not matter who created the entire narrative, but now it has completely changed. An antagonist prevailing over the heroes. Storylines like this are completely unheard of in the comic book movie genre.
The act of Thanos (vis-à-vis the snap) shook the industry to its very core. We thought Marvel was only bluffing in the theatres but they flipped the idea on its head. I wonder if the misdirection was intentional. What am I talking about, it’s Marvel, of course, it was intentional. They love messing with the fandom.
But the question is not what Marvel has already done, no sir. The question is what Marvel will do, come the release of Avengers: Endgame. The entirety of the series arc of the Marvel Cinematic Universe (spread over 3 phases nonetheless) has focused on the protection and the pursuit of the infinity stones in one way or the other. It has been largely impossible for the fandom to detach the individual story of each movie from this series arc of the ever-growing Marvel Cinematic Universe.
We have even witnessed how the infinity stones have become central to the workings of many cultures (for example the Aether aka the Reality Stone with the Dark elves) and many organizations (like the eye of Agamoto aka Time stone with the wizards of Kahmer Tahj).
The infinity stones are powerful singularities that have dictated the direction of the Marvel Cinematic Universe from day one and have taken it from the fight in the streets in Iron Man 1 to a fight to defend mass genocide in Avengers: Infinity War. The only way this series arc of Marvel comes to a close will be when these powerful singularities are put to rest.
Yes, I am implying what you think I am implying. We, at Quirkybyte along with reddit user u/NatsumeT are of the opinion that Marvel is planning more than just the end of their series arc come endgame. In fact, the very fact that the only heroes left alive are the original Avengers is the fact that there will be carnage in Avengers: Endgame beyond our imagination and moreover some unanticipated death.
Now fans have already speculated that one or more Avengers (most notably Tony and Steve) will perish at the end of the fourth Avengers movie. But this theory suggests that there is something far more sinister going on in the Marvel Cinematic Universe than just simple death of a couple of centric heroes.
The deaths are going to happen, that part is concrete (because even the studio realizes that the stakes must be upped from the last movie) but they are apparently going to hold a much deeper meaning than you all realize. Here, take a look at this Fan speculation for starters:-
The premise is certainly interesting and the speculation does make for an interesting read. But let’s take a step back and evaluate the large-scale implications of such a series close. If this theory is brought to fruition then the entire formulae for the Marvel Cinematic Universe will be flipped on its head. Now, we do realize that the speculation has some loopholes but the mere idea that each of the original Avengers will perish at an attempt to destroy all 6 infinity stones gets us riled up with anticipation and excitement.
I hope Marvel is planning something, if not similar, then just as exciting as this speculation because it would not only give a perfect send off to all the original Avengers but also ensure that the audience is uncategorizably hooked to the acts of the heroes up until the final moment when they perish (or rather are sent back to their own time in the case of cap). However, the only question I would have asked about the legitimacy of such events is whether the Avengers are powerful enough to destroy artifacts like the infinity stones in one fell swoop.
