The Justice Legion Alpha is a DC Comics superhero team, who exist in the far future of the DC Universe. Created by Grant Morrison, they first appeared in DC One Million (except The Flash, who was created by Mark Waid and first appeared in Flash 50th Anniversary Special (1990)).

In the 853rd century the institutions of the Justice League of America and the Legion of Super-Heroes have developed into the Justice Legions, various teams of superhumans who act to protect our galaxy. The highest ranking of these is the Justice Legion Alpha who have their base on Jupiter and are responsible for protecting the solar system. (The second rank is Justice Legion Beta, the third is Justice Legion Gamma, and so on.) While Alpha resembles the JLA, other Legions resemble teams such as the Teen Titans, Young Justice, the Legion of Super-Heroes, the Legion of Super-Pets , etc.

Justice Legion Alpha is made up of future analogues of modern heroes. Their membership includes:

• Superman: The latest in the Superman dynasty that stretches from mordern times to the 853rd century. One of the intervening Supermen married a princess from the 5th dimension, granting the following Supermen extra powers. Also the now god-like original Superman lives in the heart of our sun and through his immense will grants even greater powers to his decendents. Superman operates from Earth.

• Wonder Woman: A marble statue granted life by the Goddess of Truth (which is presumably the guise adopted by orignal Wonder Woman after death). She has similar powers to the original and also carries two shape changing weapons similar in nature to Diana's invisible jet. She operates from Venus.

• The Batman: Pluto is now a penal colony. When the current Batman was a child he lived with his prison-guard parents on Pluto. After a prison break the prisoners rounded all the guards into a stadium and forced their children to watch as they were gunned down. Remembering the legend of the original Batman he decided it would take someone of extraordinary will to control the prison and took command himself. He has trained his whole life to become a perfect crime fighter and also has numerous technological enhancements. His sidekick is a robot called Robin the Toy Wonder.

• The Flash: Originally from the 27th century, the time traveling speedster John Fox had met Wally West, the 20th century Flash, before he wound up in the 853rd century. He operates from Mercury.

• Aquaman: King of the oceanic planet of Neptune. Unlike the original Aquaman, he has a more fish-like appearance and psychic control over water.

• Hourman: An android based on Rex Tyler, the original Hourman. He has time travel powers.

• Starman: A direct decendent of Jack Knight. Starman monitors the artificial sun Solaris. He lives in a space station that exists where Uranus once was.
