Premiering this morning on ABC's Good Morning America, the teaser opens with brief retrospective, looking back at the idea to assemble "a group of remarkable people, to see if we could become something more." There's little time for nostalgia, however, as the swelling, inspirational music is cut short by the arrival of Thanos, and his threat: "In time, you will know what it's like to lose, to feel so desperately that you're right, yet to fail all the same."

"Dread it, run from it," Josh Brolin's Mad Titan continues, "destiny still arrives."

There's, of course, plenty to take in, from confirmation that Loki does indeed possess the Tesseract following the events of Thor: Ragnarok to the indication that T'Challa and Wakanda provide Captain America with his new adamantium shield. However, that's only for starters. There's the return of Iron Man's Hulkbuster armor, the official debut of Spider-Man's new costume, an epic battle in Wakanda, Thor's meeting with the Guardians of the Galaxy, and ... whew. Just watch it yourselves.
