'Avengers: Infinity War' Trailer Is Finally Here to Really Break the Internet

Marvel dropped the eagerly-anticipated first trailer for "Avengers: Infinity War" on Wednesday morning, after previewing different footage from the film and both Comic-Con and D23 earlier this year.

The sneak peek stars with each of the core superheroes saying, "There was an idea to bring together a group of remarkable people, to see if we could become something more, so when they needed us, we could fight the battles that they never could."

"In time, you will feel what it's like to lose, to feel so desperately that you're right then to fail all the same," Thanos is then heard saying, over shots of Doctor Strange, Bruce Banner, Tony Stark and Wong inside the Sanctum Sanctorum, Spider-Man's "Spidey Sense" coming into action and Loki grabbing hold of the Tesseract, before the Mad Titan himself emerges in all his purple glory.

There are glimpses of Spider-Man's amazing new suit, a bearded Captain America, blonde Black Widow and Vision getting his Infinity Stone ripped out of his head and Thanos flexing his Infinity Gauntlet. The most epic shot of the trailer, however, shows Cap, Widow, Bucky, Black Panther, Hulk, War Machine, Falcon and Okoye running into battle in what appears to be Wakanda.

Capping it all off: a scene of Thor -- still missing his eye after losing it in "Thor: Ragnarok" -- asking "Who the hell are you guys" to the Guardians of the Galaxy.

The cast for this movie is massive, with Robert Downey Jr., Chris Evans, Scarlett Johansson, Chris Hemsworth, Chris Pratt, Zoe Saldana, Josh Brolin, Benedict Cumberbatch, Tom Holland, Elizabeth Olsen, Jeremy Renner, Tom Hiddleston, Chadwick Boseman, Mark Ruffalo, Vin Diesel, Karen Gillan, Anthony Mackie, Paul Bettany, Dave Bautista and probably 100 other superhero stars all expected to appear in the movie.

The trailer comes after President of Marvel Studios Kevin Feige teased some major changes to the MCU lineup after "Avengers 4," which isn't due out until 2019. The movie, according to him, will "bring things you've never seen in superhero films: a finale." He added, "There will be two distinct periods. Everything before Avengers 4 and everything after. I know it will not be in ways people are expecting."

"Infinity War" hits theaters May 4, 2018.

The trailer was very different from what fans saw at Comic-Con and D23 earlier this year, see how it compared by reading a breakdown of that sneak peek below:

The footage kicked off with the Guardians of the Galaxy rescuing Thor, who crashes into the Milano's windshield as he drifts through space. It appears to happen after the events of "Ragnarok," as he's rocking his new 'do. When he wakes up onboard the Guardians' ship, his first words: "Who the hell are you guys?"

The rest of the footage was fast and furious, featuring appearances from pretty much EVERY Marvel star to date. Loki was spotted with the Tesseract, Spider-Man's seen using his Spider-Sense and rocking the gold-trimmed suit unveiled at the end of "Homecoming," Captain America's rocking a new beard, Black Panther and The Winter Soldier are both seen kicking ass and Thanos himself got a lot of screen time. Perhaps most shocking off all, however, was Black Widow's blonde hair!
