During the military and political chaos occurring in AC 195, pilot Trowa Barton is forced to abandon his XXXG-01H Gundam Heavyarms mobile suit, leaving it behind on Earth when he goes back out into space. Over the next few months, the abandoned Heavyarms finds its way into the care of guerilla rebel Sally Po. Sally, realizing the chaos will be concluded in space and that the infamous Gundam pilots will be at the very center of it, later goes into space herself, taking the Gundam with her to return it to its pilot. Aboard the independent battleship Peacemillion, Gundam supporter Howard upgrades the groundpounding Heavyarms, outfitting it to fight in space. The improvements made to the Gundam Heavyarms Kai are necessary to give the mobile suit the edge it needed to deliver its firepower against the spacebound forces of White Fang's WF-02MD Virgo II mobile dolls and the mobile suits of the World Nation military. A minor improvement is the addition of several vernier thrusters to give the Heavyarms stability in a zero-gee environment. However, the biggest improvement is the replacement of its single, large beam Gatling gun with a pair of smaller, double-barreled shell-firing Gatling guns, allowing the Heavyarms to split its devastating firepower up and tackle more targets at once. Following the defeat of the Mariemaia Army in AC 196, Trowa joins the other Gundam pilots in self-destructing his own suit, now that its mission has been fulfilled.
