The five Gundams all gather at the New Edwards Base in an attempt to kill the higher echelon members of OZ, but they discover too late they have been tricked; Heero has already eliminated the pacifist leaders of the Alliance while Lady Une and the leader of OZ, Colonel Treize Khushrenada, manipulate the only survivor, General Septum, into declaring war on the colonies (before they kill him too). The Alliance is overturned from within and OZ takes over as the new ruling power.

Relena, now on board Libra, attempts to reason with Zechs, but is imprisoned instead. After Heero installs the ZERO System in Quatre's Gundam Sandrock, Zechs adapts the system so Dorothy can control mobile dolls. Dorothy has the upper hand against the pilots until Quatre uses the ZERO System and turns the tide.

Quatre, now mentally unstable, appears in the newly constructed Wing Gundam Zero and begins to destroy various colonies one by one. Lady Une sends Heero and Trowa to fight back in the Mercurius and Vayeate, while Tsuborov, finding Une's behavior to be too lenient, stages a coup against her and cuts off the air supply to Wufei, Duo, and the Gundam engineers' cells.

The Gundam pilots on board Peacemillion refuse to join Treize, but still believe they must stop Libra and head off in that direction. Sally and Howard decide the only way to stop Libra is to evacuate Peacemillion and ram it into Libra's main cannon. Noin decides she would rather remain by Zechs' side than fight him.

Wufei fights mobile dolls and gets a rematch with Treize, questioning if Treize understands justice and the consequences of his actions. However, as Treize reveals that he does understand, he allows himself to be killed by Wufei's Altron Gundam. Duo finds the Gundam engineers while Dorothy reveals her own tragedies as she attempts to prove to Quatre in a fencing duel on Libra that war is the only way peace will be understood. Heero and Relena return to Peacemillion, where Heero asks Relena to believe in him before he takes off in the Wing Zero to find Zechs.

Hilde sneaks on board Libra to steal the blueprints and runs into Relena. When she escapes to Peacemillion, she is nearly killed until Duo arrives to fight against the rebuilt Mercrius and Vayeate, now mobile dolls programmed with Heero and Trowa's combat data. Duo reveals to Heero (from Hilde) that Relena is on Libra.

OZ plans to transport the new Taurus mobile suits to their base in Siberia. However, Lady Une sets an elaborate trap there to lure and destroy the Gundams. Duo and Quatre arrive to attack the base's ground transportation route (which is revealed to be a decoy), while Heero and Trowa attack the base's aerial route. During the battle, Zechs uses the Tallgeese to duel Heero. However, Une interrupts this when she threatens to destroy the space colonies using the missiles of Space Fortress Barge unless the Gundam pilots surrender. Doctor J responds and agrees to surrender, but refuses to hand over the Gundams. In response to this, Heero self-detonates the Wing Gundam, nearly killing himself in the process. The remaining Gundams are forced to retreat.

Heero fights Quatre in a near vain attempt to demonstrate that the colonies no longer need the Gundams, but when that fails, Trowa forces Quatre to realize his own kindness by paying the ultimate price. Meanwhile, the Romefeller Foundation proposes to replace all OZ mobile suits with their new Virgo mobile dolls and Treize is imprisoned when he refuses to support this. Lady Une, who learns of Tsuborov's treachery, is shot by Tsuborov when she unlocks Duo and Wufei's cell, allowing them to escape with their new, yet incomplete suits: the Gundam Deathscythe Hell and the Altron Gundam.
