WARNING: The following article contains major spoilers for Avengers: Endgame, in theaters now.
With reports that a new trailer for Spider-Man: Far From Home is coming in the next few days, a new rumor sheds some light on details concerning Jake Gyllenhaal's Mysterio, and his connection to the events in Avengers: Endgame.
According to MCU Cosmic, when Nick Fury introduces Spider-Man to Mysterio, the latter will hail from a "different Earth." If the rumor turns out to be true, this would officially open the door for the Marvel Cinematic Universe's own version of the multiverse, or alternate Earths/realities.
Avengers: Endgame teased alternate realities when the Avengers used Pym Particles and the Quantum Realm to travel into the MCU's past to retrieve the Infinity Stones, hoping to bring their fallen comrades back to life after Thanos' Decimation snap in Avengers: Infinity War. When Bruce Banner visited the Ancient One during the Battle of New York in 2012's The Avengers, she warned of divergent timelines being created if an Infinity Stone wasn't returned to its proper place in the timestream.
While Captain America did return the Infinity Stones in the final moments of Endgame, audiences did see changes made in the past. For example, Loki escaped with the Tesseract after the Battle of New York, and Captain America stayed in the past to grow old with Peggy Carter.
Directors Joe and Anthony Russo confirmed Steve Rogers' creation of a divergent timeline, potentially setting the stage for a future Captain America movie. With Spider-Man: Far From Home ending Phase 3 of the MCU and its second trailer reported to contain a spoiler warning for Avengers: Endgame, anticipation will continue to build until the trailer's release.
Opening July 2, director Jon Watts’ Spider-Man: Far From Home stars Tom Holland, Samuel L. Jackson, Zendaya, Cobie Smulders, Jon Favreau, JB Smoove, Jacob Batalon and Martin Starr, with Marisa Tomei and Jake Gyllenhaal. Avengers: Endgame is currently in theaters.
