A new menace known as the Silver Surfer comes to attack the Earth. With both Tony Stark and Steve Rogers dead, the Avengers (Thor, Captain Marvel, Hulk, Captain America (Falcon), Hawkeye, Spider-Man, Black Panther, Doctor Strange, Wolverine, Wasp, Ant-Man, Star-Lord, Gamora, Groot, Drax, Rocket, Vision, Scarlet Witch, Mantis, Nebula, and Bucky Barnes) must fight one last stand against the cosmic being Galactus.
A blue planet is shown floating in a dark galaxy. A text appears on the screen that says "Zenn-La". A man is talking to a girl. The girl suddenly gets mad and storms away. Galactus then says that it is time to head for Earth. Suddenly, a logo that says "Avengers: Galactic Threat" appears.
The Avengers (Carol Danvers, Bruce Banner, Stephen Strange, Sam Wilson, Peter Parker, Scott Lang, Wanda Maximoff, and Hope van Dyne) are sitting in the newly rebuilt Avengers Compound, and are discussing the events of the movie "Captain America: Legacy" (in which Sam Wilson and Peter Parker teamed up to battle the evil M.O.D.O.K), and suddenly hear an alert. They see that the entire planet of Pluto is missing, and decide to investigate.
