Myrick explained, "The armor will give them the capability to go into different environments like extreme heat or cold, or underwater, or outer space, and it'll enhance their abilities." The Avengers also featured an "A" on their costumes that was like a Star Trek comlink, where they could hit it and communicate with each other and the mansion's computer.
In order to attempt to emulate Batman Beyond, changes were made to the Avengers franchise as the series was set in the future. Myrick explained that they were "setting the series about twenty-five years in the future" and that "New York City will be a mix of future and contemporary looks, sort of the way the city looked in the movie Blade Runner (1982) but not as dark."
