Gundam Wing Endless Waltz

The Year is AC:196. With the formation of the Earth Sphere Unified Nation, all known military weapons in the earth sphere are destroyed, except Tallgeese III and the Gundams. The Gundam pilots decide to follow suit, and launch their gundams into the sun, except Wufei, who keeps his gundam. Relena is kidnapped by a group of rebels called the Mariemeia Army. Their leader is Mariemeia Khushranada, the daughter of Traize Khushranada.
Heero and Duo leave for the colony that Relena was kidnapped on, as the Preventers also do, after finding that the Neo-Titanium/Gundanium Alloy is from that colony. Heero and Duo speak with Quatre before leaving, and Quatre starts off to retrieve the Gundams. Heero and Duo arrive at the colony at the same time as the Noin and Sally of the Preventers. After a fierce fight with some Mobile Dolls and a declaration of war on the Earth Sphere Unified Nation, Duo and Heero get into the colony. Duo ends up fighting Trowa in the new model, which Trowa uses only to mask his identity. Heero ends up fighting Wufei in the Nataku. Historys and extra info: Heero's History, Duo's History(Movie only), Zechs/Milliardo/Wind appears, and Quatre and Maganac Corp. start out to get the Gundams.
Quatre heads toward the meteor that will serve as the last resting place for the Gundams. Also at this time, Heero and Duo are fighting with Trowa and Wufei in am incredible stalemate. Heero and Wufei continue battling until Trowa's Serpent attacks one last time. Duo has a flashback to when he planned to destroy Gundam Deathscythe Hell (which should have be listed as "Deathscythe"). He remembers how he failed when Professor G appeared and convinced him steal the Gundam to do whatever he likes with it. At the same time, Trowa flashbacks to when he was still the "perfect soldier with no name." He remembers helping to fix the Gundam Heavyarms Custom, when the real Trowa got into an argument over Operation Meteor. One of the co-workers shot the real Trowa in order to save his family on Earth. Dockor S stops the co-worker from trying to kill Trowa. Trowa decides to become Trowa Barton and to pilot the Heavyarms. In "real time," Trowa blows two large holes behind Duo in order for Duo to escape. He and also helps Heero to escape because of the smoke created. Also at that time, Sally and Noin find a number of Mobile Suits that were all decommissioned when the main forces were heading for Earth. Duo and Heero figure out that Dekim's real plan is to commence with Operation Meteor. By this time, Quatre is on his way to retrieve the Gundams. He uses the force created by an explosion to redirect the meteor and retrieve the suits. Dekim begins sending troops to Earth, while, surprisingly, Zechs Merquise, now known as the "Preventer Wind" tries to stop him. Zechs fails when Dekim tells him that he will drop the colony on Earth if Zechs does not stop. Duo and Heero break into the colony and find Trowa trying to stop Operation Meteor. Although they are able to stop the colony from dropping on Earth, Dekim already has his entire armada of troops on Earth. Mariemaia's soldiers surround Heero, Duo, and Trowa and Heero tells Quatre to send Wing Zero in the direction of HES-88. Heero intends to board Wing Zero in space. Heero also asks Duo another favor- he wants Duo to hit him. Duo punches Heero in the face, while Heero throws another punch at Duo. He says: "That's one for one." Heero then escapes when he breaks into a sudden run past the guards. As Duo is captured, Dekim's troops take over and it is time for Heero to pick up Wing Zero. "It's here". As Heero bring us to the third ova "Return Forever". Right outside the Earth stands Wufei, with his Altron Gundam, waiting for the arrival of Heero. Wufei flashes back to the time when he first gets his Gundam and decides to fight for justice. He and Heero went into battle, while Duo escaped from the colony. At this time Sally is setting all the people free in the colony and Trowa picks them both up to the battlefield on Earth. Heero and Wufei continue to battle as they enter Earth due to the gravity of the planet. On Earth, Noin in her Taurus and Zechs in his Tallgeese III, are doing their best to stop the war without killing a single soldier. Heero and Wufei continue to battle as they enter Earth's atmosphere. However, they stop fighting when Heero ask Wufei how many times does he have to kill the little girl. He then drops himself to the bottom of the ocean. Wufei flashes back to when Ron Shirin blew up the colony in order to save Wufei. He asks himself if he wants something like that to happen again. In the meantime, Trowa, Duo, and Quatre get their Gundams back and trek to the battlefield. They arrive just in time to help Noin and Zechs out. Witnessing the battle, Relena finally understand that peace is something you have to fight for. Although Dekim stopped her when she attempted to broadcast this message to the people, most of them that were watching received the message from her. In the battle, Dekim's troops overpowered the Gundams, and they were only left with one choice- self-detonation. Wing Zero changed it all as he appeared in the sky, and confirmed that the shelter shield was secure. After three blasts from Wing Zero, he was able to destroy the shield, but Wing Zero was also destroyed. As the shield goes down, Lady Une jumps in and saves both Relena and Mariemaia. Meanwhile, Wufei shows up with a huge amount of people that are craving peace. Dekim tries to reorganize his armada and also attempts to shoot Relena. She is save by Mariemaia, who takes the bullet for her. At the same time, a noble soldier of Mariemaia's executes Dekim. He then expresses his apologies for Dekim's betrayal to Treize's Excellency. Heero appears and "shoots" Mariemaia in order to make her feel better, and prove to her that she can be a new person. In the end Duo, Trowa, Quatre and Wufei all decide to self-detonate their Gundams. While Trowa, Duo, and Quatre discuss the problems with Trowa's name, Sally invites Wufei to join her as a Preventer. Noin and Zechs decide to form new lives. After colony 197, peace has returned to the people; weapons called Mobile Suits, including the incredible Gundams are never seen again...
