Disney California Adventure is getting a massive new land right in the middle of the park. Avengers Campus is part of a Disney Parks global story that features Marvel super heroes doing some recruiting for new heroes. Other parks that are part of the global story include a Marvel-themed land coming to Disneyland Paris and the already open Iron Man Experience and Ant-Man and the Wasp: Nano Battle at Hong Kong Disneyland.
The land will be opening in two phases much like Star Wars: Galaxy's Edge did in 2019 and 2020. Phase one of Avengers Campus, which features a new Spider-Man attraction, dining location, character meet and greets, and more opens Summer 2020.
