Future[]
In the future, the Justice League would still be around and protecting the Earth. The team's roster had shortened, eventually after all the years, to the amount you see in "Batman Beyond" and the episode of "Justice League Unlimited", "Once and Future Thing Part Two: Time Warped" (Superman, Static, Warhawk, Kai-Ro, Barda, Micron, Aquagirl, and Batman).
