The latest updates and possible spoilers for "Avengers 4" reveal Tony Stark's plan to save the whole universe from the Infinity Stones' effect. A new theory hints that Tony may have traveled back in time during the events of the first "Avengers" film and changed it.

Instagram page kpow_ok posted a photo featuring Gwyneth Paltrow wearing Iron Man armor, indicating that Pepper Pott's will become the superhero, Rescue. The events of the film are said to take place five years after "Infinity War" as the surviving heroes make their last stand against Thanos to save the universe and their fallen friends.

Tony Stark's time travel mission

According to Screen Rant, Tony Stark will travel back to the Battle of New York in the first "Avengers" movie and change certain events. Based on the leaked behind-the-scenes production photos, it seems that Tony is trying free Loki from Thor's custody by disguising himself as a S.H.I.EL.D. agent. Loki has vital information to make early plans and the move will create some major changes to the timeline going forward to prevent the infamous "Thanos Snap" from ever happening.

Tony's time travel experiment became possible when Scott Lang (Ant-Man) introduced him to the Quantum Realm as the energy from it could create a portal through time and space. Tony will use this gamble to not only save the whole universe, but to revive the fallen heroes such as Spider-Man, Black Panther, Doctor Strange, Star-Lord, and many more.

Pepper Potts becomes Rescue

The Instagram page's kpow_ok photo shows Gwyneth Paltrow's character wearing a blue Iron Man suit and working on a scene due to the green background set. Express UK reported that her armor is designed differently as it shows a more feminine look as opposed to the muscular and bulky build of the standard Iron Man armor.

In the Marvel comics, Tony Stark created a suit specifically for Pepper Potts and named it "Rescue." Unlike the Iron Man suits, the Rescue armor is not designed for combat, but for emergency response and provides support for rescue missions. It has no visible weapons with the exception of the standard Repulsor blasters.

Pepper Potts has been a major supporting character in the Marvel Cinematic Universe and the very reason why Tony keeps saving the whole world from extraterrestrial threats.

It was previously reported that Tony will build the Proton Cannon to match the power of the Infinity Stones. There are also matching white space armor for the team, hinting a major battle between the heroes and Mad Titan's forces.

"Avengers 4" will premiere in cinemas on May 3, 2019.
