For fans anticipating the X-Men and Fantastic Four joining the Marvel Cinematic Universe, a new fan-made animated trailer for Avengers 4 offers a look at the united front of superheroes as they stand up to Thanos.

The Mad Titan may have prevailed with wiping out half of the universe in Avengers: Infinity War, diehard Marvel fans know one final confrontation will take place in the fourth Avengers film. Though the chances of Avengers 4 including the X-Men and Fantastic Four after Disney's purchase of 20th Century Fox's assets are very slim, it hasn't stopped YouTuber Bigoso Animations from delivering the dream scenario.

The trailer jumps ahead to the year 2025, as a memorial has been built for the heroes who fell when Thanos snapped his fingers and erased billions of lives across the universe. Monuments to Spider-Man, Scarlet Witch, Falcon and Winter Soldier are shown as Captain America and Black Widow look on.

We then move to Iron Man observing a monitor detailing his plan to time travel back to 2018. With Iron Man's leap through time successful, we see Thanos after he raided Xandar for the Power Stone, a reunion with Secret Avengers (Captain America and Black Widow), the debut of Ronin and recruitment of Marvel's Netflix heroes of Daredevil, Luke Cage, Iron Fist and Jessica Jones.

The major money shot comes from Thanos squaring off with every single hero in the MCU (including Captain Marvel), the Fantastic Four, Silver Surfer, Ghost Rider, the X-Men, Magneto and Daredevil (wearing an Avengers t-shirt).

Set for release on May 3, 2019, Avengers 4 is directed by Joe and Anthony Russo, and stars Robert Downey Jr., Chris Evans, Chris Hemsworth, Brie Larson, Mark Ruffalo, Jeremy Renner, Scarlett Johansson, Paul Bettany, Anthony Mackie, Paul Rudd, Elizabeth Olsen, Tom Holland, Benedict Cumberbatch, Chadwick Boseman, Chris Pratt, Zoe Saldana, Dave Bautista, Bradley Cooper, Vin Diesel, Karen Gillan, Evangeline Lilly, and Josh Brolin.
