The Calamity Gundam is one of three new
Earth Alliance
prototypes deployed in the invasion of the
Orb Union.
Based on an X100-series frame similar to that of the
Buster Gundam,
this new machine is likewise designed for long-range artillery attacks. However, with its improved
Trans-Phase Armor
and overwhelming firepower, the Calamity is far superior to its predecessor. In order to draw out its full potential this powerful
mobile suit
is assigned to
Orga Sabnak,
one of the artificially enhanced pilots the Alliance refers to as
biological CPUs.
