Bandai’s latest kit is one of three second-generation GAT-X machines, Calamity is built on the X100-series frame and inherits GAT-X103 Buster Gundam's artillery attack concept. It can also be used to provide support from the rear and is armed with several powerful range weapons, but it completely lacks any close combat weaponry. Its armament consisted of two back-mounted high-energy long-range beam cannons, a chest-mounted multi-phase energy cannon, 2-barrel ram cannon equipped shield attached to the left arm and a hand-carried plasma-sabot bazooka.

■ The head is pulled out from the body and has a built-in feature that relaxes the buffer with the collar.
■ The movable axis of the abdomen is equipped with a feature that swings back and forth and left and right. The crotch axis also swings downward, creating a powerful pose with a wide stance.
■ Equipped with interlocking movement that the front skirt tilts toward you so that it does not interfere with the left-right rotation of the torso when bending forward. The front block has a structure that hides the gap between the blocks by pulling it up when the fuselage warps.
■ Arms are connected to shoulder armor with ball joints. Movable with a combination of shoulder swing, elbow double joint, and wrist double joint.
■ "Todes block" is attached as a handheld weapon. Equipped with a movable gimmick that swings the grip toward you.
