In the future, people have left the Earth to live in colonies in space. To prevent a war from breaking out, the colonies agreed to hold the Gundam Fight, where each colony constructs a huge machine employing as many racial sterotypes as is humanly possible, and have them fight on the Earth. Whomever was the victor would be given the right to rule the universe (dunno how that works...) Domon Kasshu, a gundam fighter from Neo-Japan, has been sent to Earth to locate and destroy the Devil/Dark Gundam, (they changed the name to Dark in the Cartoon Network dub) being piloted by his brother Kyoji. Along the way, he meets many and varied rival gundam fighters, some of whom become his pseudo allies.<br />
