Avengers 4: 8 Major Plot Predictions
7. Ant-Man, Time Travel And The Quantum Realm
Leaked Avengers 4 set photos (courtesy of JustJared) have confirmed that it will revisit 2012's The Avengers in some capacity.
Captain America can be seen sporting his bright, spangly outfit from the original team-up movie, and the destruction surrounding the character looks similar to the mess created during the Battle of New York, when Loki commanded his Chitauri army to take over the Earth.
With half the Avengers dead, the team's only option might be to travel back in time and alter past events, to try and stop Thanos from completing the Infinity Gauntlet.
And if the remaining heroes are unable to retrieve the Time Stone from Thanos' clutches, their other time travel option may lie with Ant-Man and the Quantum Realm.
The Quantum Realm is a place where space and time are said to be irrelevant, and Ant-Man can access it by shrinking to a subatomic level. The movies haven't yet explained precisely how Quantum Realm time travel would work, but perhaps Lang could also provide some of the other Avengers with shrinking devices, so that he could take people back in time with him.
Ant-Man can even be seen in those set photos alongside a present-day Tony Stark and a 2012-era Captain America, lending more credence to this whole idea.
Given the unpredictability of the Quantum Realm, maybe the team can't just travel back to before Thanos' finger snap and stop him there. Perhaps they're not actually aiming for the Battle of New York, but this is where they end up, and they try to improvise a solution from here.
