After Colony (A.C.) 195. Mankind has moved into space. Thousands of people live on giant orbiting space colonies called "Sides." However, the Earth Government, which rules the colonies, is unjust and cruel. A group of revolutionaries builds five robotic weapons called Gundams and plans to send them to Earth to begin their fight for independence. Piloted by five young men, these Gundams carry the hopes and dreams of freedom of the colonists with them as they descend to Earth to begin Operation Meteor!
Six long months have passed. The Raalgon Empire has developed a horrible new type of weapon, and Tylor has been charged with the duty of intercepting it as it is being transported. But when all that could go wrong does go wrong, the crew members of the Soyokaze find themselves at the mercy of their enemies. As the hours tick down toward their execution, the crew wonders: has their irresponsible captain misled them? Or is this all a part of some greater strategy?
In the Year F.C. (Future Century) 60, much of mankind inhabits space colonies which orbit the Earth. Dominance over the colonies is decided once every four years by a large tournament in which each nation sends a single representative to fight the others with a giant robot called a Gundam. Domon Kashuu is selected to represent Neo-Japan in one of these tournaments, but he fights less to ensure his nation's victory than to find his brother, who has been blamed for the deaths of Domon's parents and the disappearance of a very dangerous weapon, the Devil Gundam (Dark Gundam).
The year is Universal Century 0088. Directly after the end of the Gryps War, Haman Karn and her army of Zeon remnants on the asteroid Axis begin their quest of reviving the lost empire of the Zabi's, and proclaim themselves as the Neo-Zeon. With the Earth Federation as hapless as ever, only the Anti-Earth Union Group (AEUG) is able oppose the plans of Neo-Zeon. In need of all the help it can get after being decimated in the previous war and losing many of its key members, the AEUG ship Argama enlists the aid of a young junk collector from the Side 1 colony of Shangri-La named Judau Ashta to pilot its newest mobile suit, the ZZ Gundam.
Universal Century 0087, 7 years have passed since the end of the One Year War between the Earth Federation and the Principality of Zeon. The Earth Federation has created an elite task force, known as the Titans, who are responsible for hunting the remaining Zeon forces. However, the power-hungry Titans have spurred the creation of a rebellious faction called the Anti-Earth Union Group (AEUG).
