This New 'Spider-Man: Far From Home' Trailer Teases A Post-'Endgame' Multiverse — VIDEO

The first Endgame spoiler-filled trailer for Spider-Man: Far From Home is here, and fans are finally going to get a chance to see how the events of Avengers: Endgame are going to affect Peter Parker (Tom Holland), and the world. Spoilers for Avengers: Endgame ahead. This new Spider-Man: Far From Home trailer teases a post-Endgame multiverse in the Marvel Cinematic Universe, and it's going to open up the world to a whole new host of threats, and possibilities.

In the new trailer, it looks like Peter has grown into the role of the friendly neighborhood Spider-Man he always wanted to be. He's running around, helping out the local police, and even joking with them about being the new Iron Man (RIP). Though, personally, it's clear that he's going through a lot in the wake of losing Tony Stark, who died in Endgame, sacrificing his life to defeat Thanos once and for all. Luckily, he's got Happy on his side, and Nick Fury, chasing him across the world to ask for his superhero expertise.

This second Spider-Man: Far From Home trailer also teases a budding romance between Peter and MJ, who definitely knows about Peter's double life, and is clearly the smartest person in this high school. But, of course, the most exciting, and confusing, thing about this trailer is that it introduces the multiverse.

Quentin Beck aka Mysterio (Jake Gyllenhaal) is introduced to Peter as a superhero from Earth, "just not ours," as Fury explains. According to the ex-S.H.I.E.L.D. director, Thanos' snap tore a hole in the world's dimension, opening up a portal to other-worldly villains, like the giant sand, water, and fire monsters seen in the trailer (if those are the real threats).

Needless to say, the possibilities of a multiverse in the MCU are endless, and fans on Twitter are absolutely exploding with theories.

More specifically, fans are suggesting which superheroes could now be included in the MCU thanks to the multiverse — heroes like the X-Men or Miles Morales.

The X-Men could pop up in the MCU now that Disney has the film rights to the characters (previously owned by Fox). Though Marvel Studios President Kevin Feige recently told io9 that the X-Men wouldn't be joining the MCU anytime soon, noting that the superhero team wasn't in the studio's current 5-year-plan. Regardless of how long it takes for the X-Men to come into play, opening up the MCU multiverse offers them the perfect opportunity to come in and join Spider-Man, or Black Panther, or whatever other heroes want to team up with the mutants in the future.

And then there's Miles Morales, the hero who recently made his big screen debut in Spider-Man: Into The Spider-Verse. Miles is, essentially, another Spider-Man, and while his existence was teased in Spider-Man: Homecoming, the multiverse could allow for him to appear sooner rather than later.

Granted, these are all just hopes and dreams of Marvel fans. And, the multiverse has not yet been officially confirmed. Just because Peter says there's a multiverse in this new trailer doesn't necessarily mean he's right. That said, Endgame did create the possibility of alternate timelines, so it does seem awfully likely that the Avengers' fight against Thanos did open up the fabric of space and time into these new worlds.

One thing's for sure: Peter Parker is going to have his hands full juggling the possibility of threats from other universes and the stress of making his move with MJ. The perils of a teenage superhero truly know no bounds.
