Mobile Suit Gundam SEED begins when the neutral space colony Heliopolis is attacked by ZAFT, a military organization composed of Coordinators.
Coordinator Kira Yamato pilots the mobile suit GAT-X105 Strike to protect his friends on the Naturals' ship Archangel from potential enemies as they head towards Earth.
Despite fighting on the battlefield various times alongside the Naturals' military organization the Earth Alliance, Cagalli is later revealed to be daughter of the leader from the neutral country of Orb.
After helping her new allies to stop the war, Cagalli becomes the leader of Orb, a role mainly explored in the series' sequel, Mobile Suit Gundam SEED Destiny.
She attended ZAFT military academy together with her sister Meyrin Hawke and fellow pilots Shinn Asuka and Rey Za Burrel.
As he lies dying in Athrun's arms, Patrick tells his son to fire GENESIS on Earth and make his vision of a Coordinators' world come true.
In the closing days of the First Alliance-PLANT War, Canaver led Clyne Faction loyalists in a coup d'état of radical ZAFT leadership, before opening the PLANTs to negotiations with the Earth Alliance, after which, she became the Chairwoman of the Provisional Supreme Council.
[15] Durandal is a man of science and medicine rather than politics, with the stated agenda of ending all conflicts between humans, especially the chasm between the Naturals and the Coordinators, i.e. the Earth and PLANT.
After Lord Djibril's death, Durandal proposes his "Destiny Plan", which is immediately opposed by the Atlantic Federation, the Kingdom of Scandinavia, and Orb.
Durandal was shot by Rey, who through Kira's reasoning, saw that the Destiny Plan paid too high a price for peace and it would rob humanity of free will.
During the series it is revealed that he, like Rau Le Creuset, is a clone of Al Da Flaga, created as a transaction in exchange for the funds to finance his Ultimate Coordinator project.
[2] Lord Djibril (ロード・ジブリール, Rōdo Jiburīru) is a member of the secret society made up of the leadership of the military-industrial complex "Logos", and is also the successor to former Blue Cosmos leader, Muruta Azrael.
When Djibril learned from Neo Roanoke that ZAFT forces were the instigators of the colony drop, he submitted the evidence to the people of Earth and Atlantic Federation President Joseph Copeland, thus starting the Second EA-ZAFT War.
Together with her comrades Sting Oakley and Auel Neider she infiltrates the PLANT colony Armory One and, with the help of some ZAFT-soldiers, they steal three new Gundam-type mobile suits.
Despite Shinn's attempts to keep her away from war, Neo makes her pilot the gigantic transformable mobile armour GFAS-X1 Destroy to attack a large swath of western Eurasia.
During the Battle of Crete his Gundam is destroyed by Shinn Asuka when the latter throws the beam javelin of his ZGMF-X56S/γ Blast Impulse into the abdomen of the Abyss, causing it to crash into the sea and explode underwater, and killing Auel in the process.
[4] Sven Cal Bayang[21] (スウェン・カル・バヤン, Suwen Karu Bayan) is one of the main characters of the ONA side story Mobile Suit Gundam SEED C.E.
Orphee is defeated by Kira and Lacus in battle at the end of the Foundation conflict and dies alongside fellow Accord Ingrid Tradoll.
[2] Mu La Flaga (ムウ・ラ・フラガ, Mū Ra Furaga) is a veteran mobile armor ace, and a longtime rival of ZAFT officer Rau Le Creuset, with whom he demonstrates a strange extrasensory connection—and whom he later finds out to be his brother, created as a clone of his father.
He is successful in rescuing Athrun and the two escape to the Eternal, a new ZAFT support ship stolen by the Clyne Faction, which has his former superior Andy as a captain.
[2] Andrew "Andy" Waltfeld (アンドリュー・バルトフェルト, Andoryū Barutoferuto) also known as Desert tiger is the commander of the ZAFT forces in the PLANT-pledged African Community, headquartered at Banadiya.
After discovering Rau Le Creuset's true intentions to destroy the universe—confirming his longtime suspicions—he defects from ZAFT and assists the Archangel's goal in ending the war.
[2][3] Tolle Koenig (トール・ケーニヒ, Tōru Kēnihi) is one of Kira Yamato's friends who lives on the neutral colony Heliopolis, the boyfriend of Miriallia Haw.
[2] Nicol Amalfi (ニコル・アマルフィ, Nikoru Amarufi) is the youngest member of the Le Creuset team; he pilots the GAT-X207 Blitz, which he steals during the raid on Heliopolis.
Seeing how both the Earth Alliance and ZAFT had become controlled by genocidal individuals such as Muruta Azrael and Patrick Zala, Dearka retakes his Buster and fights alongside the Archangel.
In a combination of Dearka Elsman's words and witnessing the destructive power of the Genesis, Yzak sides with the Archangel in order to stop ZAFT's plan on destroying Earth.
Heine is decidedly an optimistic, but realistic, soldier who did not stand too much on ceremony, and was also quite talkative and earnest in his attempts to raise the morale of his fellow pilots.
While attempting to counter-attack Kira, Heine and his GOUF Ignited are sliced in half by Stella as she tried to attack the Freedom, destroying the suit and killing him in the process.
A former ZAFT recruit and old classmate of Shinn Asuka and Lunamaria Hawke, Agnes Giebenrath is introduced as a pilot for Compass in the squad led by Kira Yamato.
Associated members to the group include Captain Murrue Ramius, Ensign Miriallia Haw, Meyrin Hawke, and Former ZAFT Lieutenant mobile suit pilot and current ORB admiral Athrun Zala.
