Technology & Combat Characteristics
Although developed under Earth Alliance's "Actaeon Project", the GAT-X131B Blau Calamity is actually an independent project by the Actaeon Industries. Developed by Valerio Valeri, the Blau Calamity is an enhanced variant of the GAT-X131 Calamity Gundam with double the armament and a new pair of combined shields. Due to the additional weaponry, the Blau Calamity is twice as heavy as the original Calamity. Thus, hover units, which are changed to thruster units when the mobile suit is deployed in space, have been added to its legs to ensure sufficient level of mobility.
Despite being a ranged unit, the Blau Calamity has no problem engaging melee combat specialized mobile suits piloted by normal pilots within close range due to its heavy firepower. The Blau Calamity is designed from the beginning to battle alongside the GAT-X370G Gelb Raider Gundam and GAT-X252R Rot Forbidden Gundam, where it is responsible for ranged attacks. The mobile suit is installed with the power extender, and later upgraded with the Trio System, which improves its cooperation with the other two mobile suits during battle, as well as the combat AI, 80. The installation of 80 greatly improves the mobile suit's performance and turns it into an AI controlled machine.
History
The first of the enhanced second generation GAT-X machine created by Valerio Valeri under the "Actaeon Project". The GAT-X131B Blau Calamity Gundam was first seen battling the ZGMF-2000G2 GOUF Galactica when the latter mistook the former for an enemy unit trying to attack the village it was protecting. In truth, Blau Calamity was simply on its way to its testing ground. Despite being a ranged unit pulled into a melee battle, the Blau Calamity still bested the GOUF Galactica easily due to its overwhelming firepower.
Valerio Valeri then used the mobile suit in a simulation battle against the GAT-X105E Strike Noir Gundam to gauge its combat performance. When the Blau Calamity was about to lose, Valerio Valeri stopped the battle and introduced the GAT-X370G Gelb Raider Gundam. He also rewound the battle to the beginning, and the result was that both of his mobile suits easily defeated the Strike Noir.
Later in space, the Blau Calamity and Gelb Raider intervened in the battle between ZGMF-X56S/ι Destiny Impulse Gundam R and MBF-P02 Gundam Astray Red Frame, which was controlled only by 8 as Lowe Guele was thrown out of Red Frame's cockpit earlier. Both mobile suits defeated the Destiny Impulse R and captured 8. Subsequently, the Blau Calamity, Gelb Raider, and GAT-X252R Rot Forbidden Gundam were fitted with the Trio System and deployed in an ambush to destroy the Destiny Impulse R and DI Adaga. The battle was a stalemate initially, but the three mobile suits soon managed to forced the self-destruction of the DI Adaga. However, DI Adaga's Destiny R Silhouette ejected beforehand and then escaped with the Destiny Impulse R.
After the combat AI, 80, was successfully developed, Valerio Valeri immediately installed it on the three enhanced second generation GAT-X machines. The trio of AI controlled mobile suits were then used to defend against a large scale attack from Destiny Impulse R and numerous DI Adagas. The three mobile suits were destroyed on Earth a week later by the MBF-P02 Gundam Astray Red Dragon in a duel between Valerio Valeri and Lowe Guele.
