After successfully saving Captain and Zero, Chief Haro, leader of the S.D.G.(Super Dimensional Guard) makes Shute an official member of the Superior Defender Gundam Force. Good thing, too, because the Dark Axis commander has added the weapons-loving Destroyer Dom to the Neotopia invasion force!

Bakunetsumaru and Dr. Bell Wood are in a fierce argument. Bakunetsumaru needs the Dimensional Transport Device repaired, in order to return to Ark, but Bell Wood feels fed up with the project. Meanwhile, four Zakos take control of a massive digging robot, and use it to wreak sub-terrenian havoc!

A slip-up with Bell Wood's Dimensional Transport Device sends the Gundam Force to the ruined kingdom of Lacroa, Zero's homeland. there, they meet three triplets who survived the Dark Axis invasion, and Talgeese, Knight of the Tempest, a warrior who joined the Dark Axis!

Fed up with the failures of his usual lackies, the commander calls in two renegade Musha Gundams from Ark. One Musha, Ashuramaru, has a bone to pick with Bakunetsumaru, and won't rest until the score is settled!

It's another peaceful day in Neotopia, and the Gundam Force are starring in a movie. But the overacting is cut short when the Dark Axis attacks Blanc Base with the Big Zam, a virtually unstoppable super-tank!
