Another day, another Avengers: Endgame theory. One of the biggest questions surrounding the film is who is going to rescue Tony Stark from drifting in space. Other questions ponder how Scott Lang will escape the Quantum Realm, but the biggest question of all is how will Thanos ultimately be defeated?
Screen Rant is offering up a new theory surrounding the defeat of Thanos, and it might be one of the wilder theories out there. The new theory suggests Tony Stark will recreate Ultron in order to take down Thanos. Yes, Ultron. The same murderous A.I. who wanted to wipe out all life on planet Earth in the second Avengers film. Thankfully, in the nick of time, the Avengers stopped Ultron from dropping Sokovia to the Earth creating a cataclysmic event.
While Ultron was created to defend the Earth in Avengers: Age of Ultron, the program evolved into something worse, which wanted to accomplish the exact opposite of Tony and Bruce Banner's intentions. Avengers: Age of Ultron was the first time "endgame" was spoken in the MCU, most specifically when discussing the creation of Ultron. Tony wanted to create a suit of armor around the world because the threats from above were the ultimate endgame, not the arms dealers they were used to fighting on Earth.
