The MSM-04 Acguy (アッガイ Aggai) is a mass-produced amphibious mobile suit, it was featured in the anime series Mobile Suit Gundam.

Technology & Combat Characteristics

Following the Zimmad Company's MSM-03 Gogg, the Zeonic Company produced their own amphibious mobile suit for the Principality of Zeon, the MSM-04 Acguy. Acguys used many of the same parts and components as the MS-06F Zaku II, including twin Zaku II F-Type Minovsky ultracompact fusion reactors. However, even with the twin reactors, the Acguy left only a trace heat signature, making it effective for stealth and infiltration operations.

The Acguy's weapons consisted of four 105mm vulcan guns mounted in the head. In its right forearm was a mounted mega particle gun. The right forearm also had extendable claws (along with an extendable arm to increase striking distance) for striking the Earth Federation's mobile suits and property. In the left forearm was a mounted six-tube rocket launcher. Some models also had rockets in the right forearm, replacing the mega particle cannon and claws, and other models had machine guns in the forearms.


  • 105mm Vulcan Gun
Small pocket turrets found on the top of the head. They release a burst of gun fire for close combat and for taking out smaller units.
  • 6-tube Rocket Launcher
Rockets can be fired from its left arm to destroy mobile suits, land vehicles, and buildings. The missiles are usually fired individually.
  • Mega Particle Cannon
High-density lasers can be fired from the right arm to pierce enemy armor and buildings for effective damage. Often used at medium to long range.
  • Claw Arm
The arm is used to crush enemies with its sharp edged blades being able to stab mobile suits. It is also used for grappling as seen during the invasion of Jaburo, when a group of Acguys were traversing the tunnels of Jaburo.

Special Equipment & Features

  • Interchangeable Forearms


The Acguy was a decent amphibious mobile suit, mostly due to its ability to sneak into bases undetected by enemy forces. Several MSM-04 Acguys sneaked into the Federation's Jaburo General Headquarters on November 30, U.C. 0079 on a covert mission to destroy the Federation's mobile-suit production facilities, which were being used to produce their RGM-79 GM mass-produced mobile suit.
