The GAT-X131 Calamity Gundam is a Mobile Suit in the anime series Mobile Suit Gundam SEED. It is piloted by "Biological CPU" Orga Sabnak.

Technology & Combat Characteristics

One of three second generation GAT-X machines, Calamity is built on the X100-series frame and inherits Buster's artillery attack concept. It can also be used to provide support from the rear and is equipped with several powerful range weapons, but it completely lacks any close combat weaponry. Its armament consists of two back mounted high-energy long-range beam cannons, a chest mounted multi-phase energy cannon, a dual ram cannon equipped shield attached to the left arm and a hand carried plasma-sabot bazooka.

Thanks to its Trans Phase Armor, a new and energy efficient form of the Phase Shift armor, Calamity has a longer operational time than the first generation GAT-X machines and also has more energy for its power-hungry beam weapons. Thanks to the powerful thrusters installed around the body, it can hover over deserts or bodies of water easily. However, as it lacks true flight capability within the atmosphere, it often has to ride on top of GAT-X370 Raider when the latter is in MA mode to keep up with its flight-capable sister units when moving to the combat zone. In this configuration, Calamity uses Raider much like ZAFT suits use the Guul subflight lifter. The control system of the Calamity is very complex and its customized OS can only be used by the "Biological CPU".


  • "Todesblock" 337mm Plasma-Sabot Bazooka
A hand carried shell-based weaponry, it has a high rate of fire and causes serious damage and shock around the impact area.
  • "Schlag" 125mm High-Energy Long-Range Beam Cannon
A pair of backpack-mounted beam cannons which rise up over the shoulders. They have excellent rate of fire and destructive power, and are capable of easily destroying an enemy force from range.
  • "Scylla" 580mm Multi-phase Energy Cannon
A high powered energy cannon mounted in the upper torso section of the Calamity. Based upon the same cannon incorporated into the GAT-X303 Aegis, it can deal serious destruction to anything that gets in the Calamity's path with a single salvo. It can be used to discourage enemy units from closing in and is often used in conjunction with Calamity's other weapons for a pure destructive barrage.
  • Anti-beam Shield
Attached to the left forearm and/or handheld, the shield is made out of materials derived from the outer armor of spaceships like the Laurasia-class. As a result, it is light yet superhard. In addition, its surface has been given anti-beam treatment and the sharp tip can be used as a weapon during close combat.
  • "Kaefer Zwei" 2-barrel 115mm Ram Cannon
A second pair of beam cannons that is mounted on the shield, it also has an excellent rate of fire.

Special Equipment & Features

A new version of the PS armor, Trans Phase armored suits do not change color when the armor is activated. It is a two-layer armor system with the PS armor in the inner layer activating only when the outer armor is breached. This design thus helps to reduce energy consumption and allows the equipped suit to have a longer operational time as well as for more power to be reserved for the suits's weapon.


In mid CE 71, the Earth Alliance collaborates with Muruta Azrael's Azrael Conglomerate to build three second-generation mobile suits. One of these is the GAT-X131 Calamity, a long- range artillery mobile suit, whose "Biological CPU" was Orga Sabnak. A close combat variant of the Calamity is also created, the GAT-X133 Sword Calamity. The Calamity is first used in the conquest of neutral Orb, then sent to space and assigned to the Archangel-class assault ship Dominion under the supervision of Azrael, who is also the leader of the anti-Coordinator terrorist group Blue Cosmos. Near the end of the war, it is destroyed by Athrun Zala in the ZGMF-X09A Justice; equipped with the METEOR MS Support unit.



Notes & Trivia

  • Calamity's head crest displays the text "SEI X-131" (which means "Six" in Italian), and it is a reference to the Calamity being the sixth mobile suit developed as a second generation MS by the Earth Alliance.
  • Despite these weapons, Calamity does not possess an Igelstellung CIWS vulcan
  • The design of Calamity may have been inspired from the RX-78-6 Mudrock Gundam.
