AEUG member Quattro Bajeena infiltrates the colony where civilian Kamille Bidan lives, searching for the Federation's new Gundam Mark-II. Kamille starts a fight with Jerid Messa of the Titans while on his way to take a look at Bright Noa's current ship.

The Titans believe that Quattro is the Red Comet. Kamille steals one of the three new Gundams and escapes with him. Bright challenges Bask Om about running military tests in civilian colonies but the Titan Kacricon Cacooler doesn't have respect for Bright.

Commander Jamaicon kidnaps Kamille's parents to use as hostages for an exchange with the stolen Gundams. Titan Emma Sheen delivers a ransom letter to the AEUG ship while Jerid is given a mission to shoot a capsule containing a bomb if any rescue attempt is made.

Jerid and Kamille fight in their Mobile Suits while Emma attempts to stop the battle. Bask tasks Emma with stealing the AEUG's new mobile suits, but she frees Kamille's father and takes the Gundams back to the AEUG instead.

Bask returns to the commandeered colony and turns over the Titan's operation to Jamaican. Kamille's father steals the AEUG's Mobile Suit in an attempt to give it to the Titans. Quattro chases after him while AEUG Commander Henken uses the Argama to help in the battle. Henken believes that Quattro is Char Aznable.

The Titans' ship Alexandria continues to follow the AEUG ships Argama and Mont Blanc. The AEUG hold off an attack by Jerid and Lila Milla Rira while AEUG member Reccoa Londe leaves on a classified mission to Earth.

AEUG leader Blex Forer offers Kamille a chance to join as an AEUG member. The ship heads for Colony 30 where 3,000,000 protesters were gassed to death. Lila chases Kamille into the colony.

The AEUG's Argama and the Titans' Alexandria both arrive at the Moon. Jerid and Kamille battle in their Mobile Suits. Quattro meets with Wong Lee, the financial supporter of AEUG and owner of the Mobile Suit manufacturing company, Anaheim Electronics.

Reccoa attempts to infiltrate the Federation base at Jaburo and meets Kai Shiden. On the Moon, Anaheim gives new Mobile Suits to both the AEUG and the Titans. Quattro, Apolly, Roberto and Kamille attempt to steal the Titans' new suits at Granada but Kacricon is ready to defend them.

The Alexandria destroys the AEUG's moon base, but the Argama and the new AEUG ship Radish escape and head to Earth. The AEUG ships pick up a distress call from Bright Noa's shuttle, currently under attack from a pilot named Paptimus Scirocco.

Henken promotes Bright to Captain of the Argama and leaves for the Moon as the AEUG fleet heads for Earth. Scirocco believes he can stop the AEUG at Earth, and he, Jerid, and Kacricon attack Emma, Kamille, and Quattro as they descend through the atmosphere as the danger of burning up completely becomes more real.

Reccoa and Kai attempt to escape their prison cell. Quattro is suspicious of Jaburo's light defenses, and Apolly learns that a nuclear bomb is planted on the base. With no possible way to defuse the bomb, everyone scrambles to escape the base before it detonates.

Karaba member Hayato Kobayashi pilots the airship Audhumla to meet up with the AEUG forces at Kennedy Spaceport. Kai informs Hayato that Quattro is indeed Char. Apolly attempts to launch an ancient Space Shuttle to evacuate the Jaburo escapees to the Argama.

The Titans' airship Sudori pursues the Audhumla. Amuro Ray and Katz escape from Federation spies that have been keeping an eye on Amuro since the One Year War and join up with Karaba. Cyber Newtype Rosamia Badam attacks the Karaba ship, and Amuro aids in the battle. Char and Amuro meet for the first time since their battle at A Baoa Qu.

Amuro learns that Hayato intended for Amuro and Katz to join him. Beltorchika Irma arrives on the Audhumla. The Sudori chases the ship over San Francisco and Rosamia heads out to attack. Katz steals the Gundam to fight Rosamia and Kamille and Char head out to defend him.

The Audhumla heads for a base covered in heavy fog where a shuttle is waiting to transport Char, Kamille, and Katz back to the Argama but the Sudori launches an attack. Katz convinces Char to leave for space with him while the rest escape back to the airship. Another letter from Kai gives Hayato his next move.

The Sudori gets reinforcements with the Psyco Gundam and pilot Four Murasame. Hayato and the Karaba attempt to meet up with Kai's contact in Hong Kong. Kamille fights the Psycho Gundam in an attempt to stop the destruction of the city.

Four and Kamille meet each other in person and begin to understand each other. Ben Wooder of the Sudori takes Mirai hostage and plans to keep attacking Hong Kong until the Audhumla surrenders. Amuro offers himself as an exchange for Mirai, and Kamille helps hold off the attack during the rescue attempt.

Kamille learns that Four doesn't have any memories and they share a kiss. The Audhumla prepares to leave Hong Kong while Ben Wooder attempts to pilot the Psyco Gundam. Four takes over piloting and Kamille and Amuro fight against her.

Hayato plans to attack the Titans' base in New Guinea to steal a shuttle for Kamille and Amuro to return to space, as the Argama has returned to Earth orbit. The Psyco Gundam continues in its pursuit of the Audhumla, but Four soon turns on Wooder and the Sudori to help Kamille return to space.

The Titans move towards the Moon to take over Von Braun City. Scircco has pledged his loyalty to Jamitov Hymem and has provided new suits to Jerid and a pilot named Mouar Pharaoh. Kamille and Emma battle the new Mobile Suits and are no match until Fa Yuiry shows up in a ship along with Apolly piloting the now completed Zeta Gundam.

Scirocco plans his next move on his ship, the Dogosse Gier, and introduces Jerid to two Newtypes, Sarah Zabiarov and Siddeley. Kamille, Emma, Apolly, and Fa attempt to hold off their attack while Reccoa transfers new Mobile Suits to the Argama.

The Dogosse Gier and Alexandria plan to attack Von Braun City and convert it to a base for the Titans. Jamaicon lets Scirocco coordinate the attack and uses him as a shield. Char, Kamille, Fa, and Emma and the crews of the Radish and Argama defend the city.

Char and Blex leave for Earth and the city of Dakar where the Federation Council plans to give full control of the Federation to Jamitov and the Titans. Char finds Blex has been shot when he returns to the hotel room and he is given command of the AEUG. Jerid and Mouar join the Alexandria because Scirocco has left, and pilot Yazan Gable attacks the Argama.

Jamaicon plans to drop a Colony on to the base at Granada. Sarah informs the AEUG, and Kamille believes it is because of Scirocco. Katz frees Sarah and she escapes. Mobile Suits are launched from the AEUG ships and Kamille, Apolly, Emma, Reccoa, and Katz battle with Yazan, Sarah and the others. The mayor of Granada wants to evacuate but Wong Lee is sure the AEUG will be successful.
