With Avengers: Infinity War unleashed, followers of the Marvel Cinematic Universe can't stop discussing their predictions for the sequel. While it won't hit theaters for another year, fans are diving into Avengers: Endgame theories in hopes of figuring out where Marvel will go in Phase Four.

Plenty of questions about Avengers: Endgame exist. How will THAT hero return? Should we worry that Robert Downey Jr.'s contract is finished? Fans desperately want to know, so the rumor mill has been grinding since the first audiences saw the fallout of Thanos's quest for the Infinity Stones.

Before you read any further, consider this your warning: SPOILERS lie ahead. If you're all caught up, then dive in, True Believer, to the most probable and most hopeful fan theories for Avengers: Endgame.

Of the six Infinity Stones, the Time Stone might be the most important. Towards the end of Avengers: Infinity War, while Iron Man, Spider-Man, Doctor Strange, and most of the Guardians wait for Thanos to arrive on Titan, the good doctor spends the down time getting info using the time-loop technique that helped him defeat Dormammu. Strange then gives up the Time Stone when Thanos arrives - telling Stark "There was no other way."

Let's hope so, since Thanos successfully wiped out half the Marvel Cinematic Universe. Since the villain wins and the remaining heroes are left picking up the pieces, fans are trying to figure out how Marvel will fix this. There are those online who point right back at the green rock and screaming "TIME TRAVEL!!!!!" - stating it's the only hope of undoing what Thanos's destruction. After all, the MCU won't continue without resurrecting Black Panther and Spider-Man.

Some, like Redditor /u/RahulVijh, have suggested a more specific take on the whole time travel device. They believe that Doctor Strange not only used the time-loop technique to view all the possible outcomes - they think he already put everyone - including Earth's Mightiest Heroes - in a time loop, sometime during the events of Age of Ultron. Now, while RahulVijh's theory clashes with the official MCU timeline (Doctor Strange doesn't get the time stone until after the events of Age of Ultron), that doesn't mean it doesn't hold some water:

I do not think that Strange saw all possible outcomes - rather he saw 14000604 iterations "until the heroes win". There literally is "only one way to stop Thanos". That makes even more sense because he is using the Time Stone which controls time. Alternate realities should be the domain of the Reality Stone... not the Time Stone...

I believe the time loop is also perhaps another reason why the Infinity War movie is named as such. Think about it, the war against Thanos doesn't happen everywhere in Universe - but only in specific locations like Earth, Xandar, Titan, knowhere, etc. Several other cosmic places and entities exist in Marvel's universe but are not party to this war, though of course they would affected by the outcome. The war however is infinite in iterations - in addition, at least, to the war being over Infinity Stones, the events of Infinity War on an infinite loop (though we see only one iteration) until the heroes win and break the loop in Endgame.

The Avengers Make The Ultimate Sacrifice To Defeat Thanos

After the trailer for Spider-Man: Far From Home teaser trailer dropped on January 15, 2019, fans were curious as to why everyone in Peter Parker's world seemed unfazed by Thanos's snap. After all, according to Marvel's official timeline, the events of Far From Home are supposed to take place right after Endgame. The folks over at Nerdist speculate that this is because no one remembers it happening, and Earth's Mightiest Heroes made the ultimate sacrifice to restore the world back to pre-snap. Obviously, this isn't a world where 50% of sentient beings turned to dust, as everyone's favorite webslinger is alive and very well on Earth. 

In the trailer, Nick Fury approaches Peter Parker - who is on a leisurely trip to Europe with his friends - for help. Fury doesn't enlist the help of any of the other Avengers, and Peter's handler, Happy, tells him that he is "all alone." 

The fact that Mysterio - an illusionist who is obsessed with the idea of being a superhero - decides to pop up at this time is also a good indicator that the Avengers are no more. After all, what better time to try to be a superhero than when the world's most prominent are gone? There is also a quick moment of Peter swinging through NYC, and the Avengers headquarters appears to be under construction. Some believe this is because it is being turned into a memorial for the fallen heroes.

Back in October 2018, the media learned that Katherine Langford of 13 Reasons Why fame joined the cast of Avengers: Endgame. Marvel hasn't announced exactly who the young actress will be playing, and fans have been wildly speculating how she will fit into the MCU come April 2019. 

Initially, fans were convinced Langford would be playing an older version of Scott Lang's daughter, Cassie. However, after the actress posted a photo to Instagram sporting new red hair, a new theory took hold: she could be playing the future daughter of Tony Stark and Pepper Potts. 

In Infinity War, Stark does briefly bring up the idea of children to Potts. Even Gwyneth Paltrow, who plays Potts, hinted that the couple shares a daughter. In the comics, Potts also has reddish hair. If any sort of time travel is involved in Endgame, there could be a solid chance this is who Langford portrays.

What sources initially believed was an actual LEGO ad revealing the "Endbattle in New York" set turned out to be from an off-brand LEGO maker called "Elephant JX." Nevertheless, the set features a mysterious winged creature that prompted a rather convincing theory from the Nerdist about a potential crossover between the Fantastic Four and the Avengers. 

Considering Thanos's manipulation of reality, it is entirely possible that he stumbled upon the Fantastic Four's infamous vortex of incredible power, the Negative Zone. Inside the Negative Zone, Annihilus - one of the first family's greatest villains - reigns. If Annihilus is somehow released into the MCU, Thanos could be forced to team up with the Avengers in order to defeat the beast.

The Negative Zone could also be a bridge between the Fantastic Four and Earth's greatest heroes. And the MCU is no stranger to Quantum Realms - just ask Ant-Man when he gets back from the parallel universe he stumbled into.
