Nov. 29 (UPI) -- The Avengers must defend earth from the invading Thanos and his armies in the first trailer for Infinity War.
The clip, released Wednesday, gives fans their first taste of the upcoming superhero epic which will bring together all of the heroes from throughout the Marvel cinematic universe.
Thanos, with his Infinity Gauntlet in hand, is seen arriving to face the Avengers as he throws down Spider-Man (Tom Holland) and delivers a punch to Iron Man (Robert Downey Jr.).
Another key moment involves Black Panther (Chadwick Boseman) preparing his home of Wakanda for an attack when he is joined by Captain America (Chris Evans).
"Evacuate the city, engage our defenses and get this man a shield," Black Panther says towards Captain America, who is now sporting a beard.
The pair along with the Hulk (Mark Ruffalo), Winter Soldier (Sebastian Stan) and Black Widow (Scarlett Johansson), are later seen charging into battle together.
Other Marvel characters that appear throughout the trailer include Dr. Strange (Benedict Cumberbatch), his partner Wong (Benedict Wong), Scarlet Witch (Elizabeth Olsen), Vision (Paul Bettany), Loki (Tom Hiddleston), Falcon (Anthony Mackie) and Thor (Chris Hemsworth), who appears at the end as he meets with the Guardians of the Galaxy consisting of Star-Lord (Chris Pratt), Gamora (Zoe Saldana), Drax (Dave Bautista), Groot (Vin Diesel), Rocket (Bradley Cooper) and Mantis (Pom Klementieff).
Avengers: Infinity War is set to arrive in theaters on May 4.
