The RMS-108 Marasai, also known as the MSA-002 Marasai is a second-generation mobile suit in the Universal Century timeline. It first appeared in the series Mobile Suit Zeta Gundam.
The RMS-108 Marasai was developed using Zeon design principles combined with technology pioneered by the Earth Federation during the One Year War. Technologically based on the RMS-106 Hizack, the Marasai features improved technologies, such as a movable frame, Gundarium Alloy armor instead of a titanium alloy that improves overall defense, greater sensor range, greater acceleration, and a more powerful Minovsky type ultracompact fusion reactor. It is equipped with high-power thrusters that allow atmospheric flight under gravity for a short period of time.
Alongside its technological improvements, the Marasai is also several tons lighter than Hizack when measuring its empty weight. The Marasai did not have as large a weapon selection as the Hizack however, because the Hizack was often equipped with older weapons used by Zakus, such as machine guns and heat hawks, while the Marasai used only advanced beam weapons. The Marasai's standard weapons are a beam rifle, two beam saber, and two head mounted Vulcan guns. A large shield was attached to its right shoulder, much like Zeon's Zaku line of mobile suits.
