The MSA-005M Methuss Mariner was a prototype transformable amphibious mobile suit developed by Anaheim Electronics for AEUG.

The “M” variant code in the model code denoted it as a marine type of the MSA-005.

History

Anaheim Electronics developed the Methuss Mariner during the First Neo Zeon War in response to Axis Zeon’s Earth drop operations. To expedite development and production, they modified the existing MSA-005 Methuss design rather than creating an entirely new mobile suit.

The Methuss Mariner was intended to counter Axis forces at their drop locations, with the ability to transition directly to underwater combat after atmospheric entry. However, by the time the prototype was completed, the conflict had shifted to space. This change in the war’s focus meant the Methuss Mariner never entered mass production.

Design

Anaheim Electronics built the Methuss Mariner with Gundarium alloy alloy armor, a material they developed on Axis by reproducing the Luna Titanium alloy alloy used in the RX-78-2 Gundam.

The mobile suit featured a panoramic cockpit with linear seat in its torso. For atmospheric entry, it used a detachable Flying Armor mounted on its underside, which could later serve as a watercraft. After jettisoning this component, the Methuss Mariner could submerge for underwater operations.

To enhance underwater mobility, the design incorporated a large hydro system on its back and three stabilizers — one in the crotch area and two in the rear leg armor. The Methuss Mariner could transform between mobile suit mode and mobile armor mode, measuring 28.8 meters and 24.6 meters respectively.

Armaments

The Methuss Mariner’s standard weapons were beam guns for ranged attacks, claws for melee combat, and a SUBROC launcher for underwater warfare.

Beam guns

The Methuss Mariner mounted a beam gun rated at 0.2 megawatts on each forearm. These weapons drew power directly from the mobile suit’s Minovsky reactor. The concentrated Minovsky particles could break down matter at a molecular level, allowing the beams to penetrate most armor types.

Claws

Instead of conventional manipulator hands, the Methuss Mariner featured powerful claws on each arm. These were effective in close combat, capable of tearing through both mobile suit armor and ship hulls.

SUBROC launcher

The mobile suit carried a SUBmarine ROCket (SUBROC) launcher mounted on its main body, positioned at the nose in mobile armor mode. This weapon system carried 13 rockets specifically designed for engaging underwater targets.
