Heading for Side 3, the Nahel Argama rescues an old civilian transport being attacked by Zakus. Aboard the old transport is Sarasa and Rasara of the Light tribe. However, among the civilian refugees aboard are Neo Zeon soldiers and Haman in disguise, having secreted herself into the crowd in order to make contact with Judau.

The Nahel Argama draws near to the Neo Zeon stronghold of Side 3. Heading to resupply them, Emary aboard the La Vie en Rose carelessly sends out an optical signal that gives away their position. This is picked up by the 3-D unit, subordinates of Mashymre piloting the new mobile armor Jamru Fin, who launch an attack.

Leaving the Argama on Earth, the crew returns to space in a shuttle to find the La Vie en Rose waiting with the new battleship Nahel Argama. But Judau and the others refuse when the kids are ordered off the ship. At that moment, they fall under surprise attack by Illia Pazom, a female soldier who has pledged her life to Mashymre.

Eager for a victory, Glemy awakens Ple Two from cold sleep in order to destroy the Argama. Sensing the evil presence of the Psyco Gundam Mk-II drawing near, Ple boards the half-disassembled Qubeley Mk-II to intercept it. However, she finds that both she and the mysterious pilot are able to anticipate each other's attacks perfectly...

Pressing on with her plan for rule through terror, Haman makes the decision to drop a colony. Receiving a message from Hayato aboard the Audhumla, the Argama joins with the Karaba and heads to Dublin to begin an evacuation. However, the Karaba rescue of the evacuees is interrupted when they're attacked by a mobile suit unit led by Rakan Dahkaran.

Launching in the Double Zeta, Ple manages to drive off the enemy from the Argama, but now the federal forces are demanding that they disarm. When they hear from Fa that Kamille has disappeared, the Argama's crew divide up to help her search for him. While this is happening, Ple sorties alone in the Mk-II and finds herself in a tight spot. But then she hears someone's voice...

The Argama rendezvouses with the Gundam team and sets course for Dublin. Bright heads off on his own for an interview with a federation high official at the Beech estate, but is followed by Judau. When Judau becomes violently angry with the official's lackadaisical response to the situation, he and Bright end up confined in the basement. They're saved from their predicament by Fa.

The Gundam team is attacked by August's mobile suit Dreissen unit at Chott Melrhir near the rendezvous point. Judau manages to repel the attack, but Beecha can't hide his jealousy. When August attacks them again, Beecha gets the jump on Judau and takes the Double Zeta out first. However...

Searching for Roux, Judau and the others enter Galdaaya, where they run into Glemy, whom is now leading Blue Unit. Just then, August, who is commanding the Mindra, strikes a deal with Gadeb Jasin of the African Independence Front to attack and seize Galdaaya.

Now so angry with the Argama that she's deserted, Roux enters the free-trade city of Galdaaya, where an artist named June proceeds to hit on her. Meanwhile, while wandering the desert, Glemy is rescued by the "Blue Unit" of the African Independence Front, who coerce him into being a spy sent to Galdaaya's underground city. There he meets Roux.

In shock over not knowing whether his little sister is alive or dead, Judau falls into a depression. Worried to see Judau in such a state, Roux takes it upon herself to administer some tough love. Just then, the Karaba base at El Goléa is attacked. Beecha and Mondo move to assist it, but misunderstanding Roux's motives, use her as a shield.

Ple spots Judau's crashed core fighter, which is carrying an injured Leina. Judau leaves Leina with Ple and flies back out into the battlefield in order to save his friends. But Ple wants Judau to love her and her alone, and hates Leina with a passion. One that's strong enough to kill.

The Neo Zeon occupiers in Dakar invite people from the Earth Federation to a grand party they're throwing. Among them is Leina, brought there by Glemy. Taking advantage of the Gundam team's attack, Judau sneaks into the reception hall and finally gets his heart's desire when he's reunited with Leina. But...

Hoping to end their water shortage, Judau flies out in a core fighter and ends up being helped by a woman named Masai. In accordance with desert law, she tells Judau where an oasis village is located. However, Masai attacks the Gundam team with a red Gelgoog in order to force the villagers to acknowledge her and her now-dead lover Tag.

While the Argama holds position to cooperate with Karaba, the Gundam team receives orders to go on ahead to Dakar. As the team heads for a desert base, they find themselves under attack by the Rommel unit, who have been biding their time for eight years awaiting the restoration of the Zabi family. One by one, the Gundam team crushes the Rommel unit's old mobile suits...

With the Neo Zeon forces now in control of Dakar, Judau slips away from the Argama after it makes a water landing in the south seas, and meets Taman and his sister Anu. Taman takes a large sum of money from the Neo Zeon in exchange for attacking the Argama with the aquatic mobile suit Capule. Anu worries about what her brother is about to do.

At last, the Neo Zeon forces descend to Dakar, where the federation parliament is located, in order to seize control. The Argama sets out to attack the Sadalahn and stop its descent, but Glemy leads the Sandra forces and returns fire. Amidst the battle, the brainwashed Elpeo Ple attacks in the Qubeley Mk-II.

The attack on Earth by Haman Karn's Neo Zeon fleet is now in full swing. To rescue Leina, Judau attaches bombs to the Double Zeta and then launches into battle on his own. Alone, Judau pursues the battleship Sadalahn. Haman, sensing his Newtype potential, invites him aboard.

Torres agonizes over the knowledge that his old friend Cecilia is a spy for Gottn. Amidst the confusion of Chara's escape, Cecilia escapes on her own and goes to Gottn. Giving him phony information, she gets a ticket for an emigration ship. But the trunk supposedly containing her payment has a bomb set inside...

Returning from Axis, the Argama docks at Granada on the moon to resupply. Judau, Elle, Torres, and Milly head out into Granada city, where Torres runs into Cecilia, a fried of his from childhood. But then Judau witnesses Cecilia making contact with Gottn.

Pretending to surrender with the Double Zeta as an offering, Judau once again goes to Axis. But Glemy, thinking that Judau and Roux are in a relationship, has Judau imprisoned. Judau tricks Ple into letting him go, but the angry Elpeo Ple takes Leina back and then flies off in pursuit in the Qubeley Mk-II.

Hoping to rescue Leina, Judau hides in a dummy meteor and infiltrates Axis. There, he meets a young girl calling herself Elpeo Ple. Meanwhile, having given Glemy the slip, Leina meets up with Beecha and Mondo, who have managed to get away from Gottn. Together, they try to escape from Axis.

Having taken Shinta hostage during the test of their improved main cannon, Chara steals the Core Top and flees the Argama. When Judau and the others fly out to intercept her, they find themselves facing Gottn in his new mobile suit AMX-008 Ga-Zowmn and a squad of Gaza-Cs. Judau attempts to try and retrieve the Core Top by forcibly docking his core fighter with it.

After the conflict in the Moon-Moon colony the Argama must once again dock with the La Vie en Rose for repairs. Emary reveals her feelings to Bright, who kindly lets her down and Judau tries to raise everyone’s spirit with a speech on how everyone must come together as a team, but is interrupted and punched by Elle for labeling Beecha and Mondo as traitors.

Judau is revered by the Light tribe as their messiah, but his refusal to their leader Sarasa soon has him on the run. In order to change her sister's mind, Rasara and Judau try to get the old mobile suit Cattle operational. That's when Glemy attacks in the new mobile suit Bawoo.

Losing their bearings in a debris cluster, the Argama docks at Moon-Moon, an old colony which has been forgotten by everyone. However, there the Argama is attacked by the mysterious Light tribe Taken captive, Judau seeks help from a beautiful girl named Rasara Moon.

Leina is taken to Glemy Toto and held captive aboard the Endra. The now enraged Judau is confined to the Argama's mess hall, but escapes with Elle's help. The two of them launch in the Double Zeta and Gundam Mk-II to rescue Leina. But Gottn plans to use Leina as a hostage in order to defeat the Double Zeta.

En route to the La Vie En Rose, Judau and the others abandon their duty and begin salvaging the wreckage of a Zaku II. Feeling responsible for her brother's selfish behavior, Leina and Roux set out for the La Vie En Rose themselves. But when they're attacked by Chara, Leina is thrown out into space.

Now a prisoner aboard the Argama, Gottn takes Iino hostage and escapes. Chara Soon attacks in the mobile suit R-Jarja. Just then, under Roux's guidance, the core fighter, Core Top, and Core Base begin to transform and combine. The new mobile suit Double Zeta Gundam is born!

Fa worries about Kamille, whom they left behind on the colony. Beecha and Mondo send another message, prompting Mashymre to send Gottn to try and infiltrate the Argama and make contact with these collaborators. Judau sorties in the Zeta Gundam, but his beam rifle is still unplugged...

Having finally departed Shangri-La, the Argama sets course for the La Vie En Rose. Chafing against Bright's command, Beecha and Mondo try to send a message that they're willing to sell out the Argama. Receiving their signal aboard the Endra, Mashymre sorties in the new mobile suit Hamma-Hamma.

After sneaking into a meeting of the junk dealers association, Judau and his friends mistakenly signal that the ship can use the industrial airlock hatch to escape. Gemon and Yazan, piloting two Gezes, attack the Zeta Gundam, and the Endra has the Argama in its sights. But the hatch still isn't open...

At last, Judau Ashta is a member of the Argama crew. A team of three Gaza-Ds attack, but Judau is away negotiating with the junk dealers association for clearance to open an industrial airlock hatch. They're saved from this tight spot by a core fighter flown by a girl named Roux Louka from the La Vie En Rose.

Deciding that he has no choice but to become more ruthless if he hopes to beat the Zeta Gundam, Mashymre Cello uses the new mobile suit Zssa to attack the residential area of the city. Concerned about the hospital where Kamille Bidan is being treated, Fa Yuiry intercepts it with the Methuss as Astonaige Medoz boards the Zeta, trying to prove that Judau Ashta isn't as special as the others think he is.

Junk dealer Gemon Bajack comes to Mashymre Cello, promoting his self-built mobile suit "Geze." With two Gaza-Cs as escorts, Gemon heads out to attack the Argama. But on the way, he spots a giant "Z-G" drawn in a schoolyard by Shinta and Qum. Taking it as a written challenge from the Zeta Gundam, he changes course and heads for the school.

Having been defeated by the Zeta Gundam, Mashymre Cello seizes an opportunity to strike back. As Judau Ashta and his friends search for the Argama, they happen to spot Mashymre launching into battle. Not wanting to be beaten to the prize, Judau grabs on to Mashymre's Galluss-J, hoping to stop it...

The Neo Zeon cruiser Endra docks at Shangri-La. Hoping to avoid conflict, Bright has the Argama retreat into the colony's interior. Just then, Judau successfully boards the Argama, hoping to take the Zeta Gundam for himself.

Judau Ashta flies through a pile of space debris in a mini mobile suit looking for parts to salvage. He comes across a fully intact escape pod and takes it back to Side 1 with him. There he meets up with his friends Lino Abbav, Elle Vianno, Beecha Oleg and Mondo Agake. They figure that they could get a good deal from the escape pod but when Judau decides to open it Yazan (who should be dead after Camille's fiery beam saber attack) jumps outs and takes Beecha hostage. Yazan asks for clothes so Judau goes and gets some from his house. His sister Leina questions him but he leaves to return to the others.
