Technology & Combat Characteristics

The Gigan was developed at the Pezun asteroid base as a low gravity space use mobile suit. Instead of legs, it lower body is equipped with three wheels and four auxiliary thrusters. It is possible to change the entire lower body of the Gigan, so that it is equipped with high mobility verniers for flying around in space. Its cockpit is a double-seat type to accommodate the pilot and a gunner. Its main weapon is the 180mm recoilless cannon mounted on the top of its head, which is used for long-range bombardment. For close to mid-range combat, it has a 120mm four-barrel machine gun mounted in the place of its right hand.

In U.C. 0096, the Gigan units deployed by the Sleeves had their wheels and auxiliary thrusters replaced with the same large propellant boosters used by the YAMS-130 Krake Zulu. Additionally, the 120mm four-barrel machine gun was replaced with the same Gatling Gun utilized by their customized MS-21C Dra-C.

History

The MS-12 Gigan was one of the few Pezun Project mobile suits to actually be produced and see use outside of Pezun. The Gigan was produced in small quantities and sent to many of the Principality of Zeon's bases for use as guard and defense units.

In U.C. 0096, a number of these mobile suits survived and would be used by the Neo Zeon remnants, the Sleeves. These mobile suits featured modified weaponry and propulsion systems, and were also repainted in a green color scheme and given the distinctive markings featured on many of the group's mobile suits.

In U.C. 0116, a Gigan belonging to the Zeon Remnants' Legacy fleet was seen during the siege of Trimurti satellite cannon.
