Story
Zeta Gundam takes place in UC 0087, seven years after the end of the One-Year War. After the events of Operation Stardust, which is told in Gundam 0083, the Earth Federation establishes an elite division called the Titans to hunt down the remaining pockets of Zeon resistance. The Titans become overzealous in their mission, and start to use brutal methods to reach their goals. In the end Titans become nothing more than ruthless tyrants with an ambition to rule the Earth Sphere. Two resistance groups, the AEUG (Anti-Earth Union Group/Anti-Earth United Government) and their earthbound counterparts, the Karaba (led by Mobile Suit Gundam's Hayato Kobayashi); form to unite the various existing small forces in the struggle against Titans. Their members consist of renegade soldiers of the Earth Federal forces, former soldiers of Principality of Zeon, and militia from space colonies, which causes the former enemies of the original series' One Year War to fight together against the Titans and the Federation. Most notable is Bright Noa, who returns as captain of the assault space carrier Argama, the flagship of AEUG space fleet. Char Aznable and Kamille Bidan are both ace pilots aboard Argama. Furthermore, Char become a mentor to Kamille. The series also sees the partnership and cooperation between Kamille and Amuro, and Amuro and Char. Behind the frontline, the resistance group AEUG and Karaba are supported by many companies on Earth and in Space, lead by Anaheim Electronics, a Moon-based giant manufacturing company. Besides financial support, Anaheim Electronics also provides logistics and technical supports for AEUG, including spaceships, mobile suits, and munitions.
The Black Gundam
The series begins when a thinly-disguised Char Aznable, now a member of AEUG under the alias "Quattro Bajeena", raids a Titan military base in the occupied colony Green Noah to acquire intelligence on the Federation's new Mobile Suit prototype, the black Gundam Mark-II. Kamille Bidan, a hot-headed Newtype dissident, is caught up in the raid and helps AEUG steal the Mark-II. Eventually, he joins the AEUG, initially as the Mark-II pilot, then as the pilot of the new Z-Gundam mobile suit (made by Anaheim Electronics and based on Kamille's own design). Hayato Kobayashi and Amuro Ray meet up with them shortly after the AEUG descends on earth to attack the Jaburo base but won't return to space. Both will stay on earth with Karaba while Hayato's son, Katz, will go to space with Quattro.
Things are complicated further as Paptimus Scirocco, an Earth-born Italian industrialist now based out of Jupiter serving as a "contract killer"/Mobile Suit developer to the Titans (who, unbeknownst to his government handlers, is an extremely powerful Newtype) executes his own designs. He takes over the organization as part of his bid to dominate the entire universe and enslave all Earthnoids and Spacenoids. The war between Titans and AEUG will soon escalate as Haman Karn, now leader of Axis Zeon, remnants of the Zeon empire, join the war as well, leading to a three-way battle. In the beginning, it is not clear which side the Axis Zeon is, as Haman's cunning plan is to play AEUG/Karaba and Titans/Federation against each other and take advantage of the damage from the clash between them.
