[14] Each area will feature mostly different sets of attractions and entertainment, while being strongly interconnected with each other by sharing a common narrative.

At the 2017 D23 Expo, Disney announced the Guardians of the Galaxy attraction would be joined by Spider-Man and the Avengers as part of the new immersive superhero-themed area at the park.

Disney initially announced on March 11, 2020, that Avengers Campus would open on July 18, 2020, but was delayed due to the theme parks being shut down caused by the COVID-19 pandemic and two stay at home orders issued by California Governor Gavin Newsom.

"[22] On September 11, 2022, at the D23 Expo, it was announced that an Avengers multiverse attraction was in development featuring the villain, King Thanos.

A number of additional Marvel-related shows and character interactions have appeared in the adjacent Hollywood Land area.

[14][60] It includes Avengers Assemble: Flight Force (a re-theme of the park's opening day attraction Rock 'n' Roller Coaster Starring Aerosmith that features Iron Man and Captain Marvel) and Web Slingers: A Spider-Man Adventure from California, now titled as Spider-Man W.E.B.

The experience features a dynamic "freeze frame" video sequence, created with Disney Photo Pass through 27 cameras placed around the area.

[68] It will take over part of Tomorrowland and will be themed as the Stark Expo based in Hong Kong, where guests are asked to join the Super Heroes in their battles.

On top of this, there will be new attractions and other forms of entertainment added to the land up until 2024, when a brand new Avengers themed ride will open, which was originally set to taking over the area previously occupied by Autopia.

A single titled "Welcome Recruits" was digitally released by Hollywood Records and Marvel Music on April 22, 2022.
