The RGM-79 GM is a mobile suit from the Mobile Suit Gundam Thunderbolt series.

Technology & Combat Characteristics

The RGM-79 GM is the standard mass production mobile suit of the Federation Forces. The ones used by the Moore Brotherhood in the Thunderbolt Sector differ from the standard issue model in several ways as they are customized for use in the area.

Sensors are added on the left and right of the head for better search capabilities in the debris-filled area. The GM (Thunderbolt Ver.) also has higher maneuverability and mobility thanks to apogee motors added in various body sections, including four on the circular parts on either side of the head, as well as a large backpack that has multiple thrusters. The large backpack and the machine's joints are covered in special seals to protect them from the debris.

The backpack is also equipped with two sub arms, which not only hold shields for defense, but can also retrieve spare weapons and ammunition equipped in spots the main arms are unable to reach. Lastly, the GM (Thunderbolt Ver.)'s offensive power is enhanced with the use of the Twin Beam Rifle in addition to the Beam Spray Gun.

System Features

  • Sub Arm
  • Core Block System
A central block located in the torso, it houses the mobile suit's cockpit, control systems and main power source. The core block can be ejected in case of emergency and transforms into an emergency pod.


The Moore Brotherhood deployed multiple units in the Thunderbolt sector to reclaim the area from Zeon forces' Living Dead Division. However, most of the units were heavily damaged or destroyed by the guarding MS-06 Zaku II (Thunderbolt Ver.) and MS-09R Rick Dom (Thunderbolt Ver.) that were armed with Big Guns. Io Fleming managed to survived the destruction of his GM (Thunderbolt Ver.) by ejecting his Core Block in time. Later, whatever could be salvaged was used to repair those that were still capable of fighting. During the Battle of A Baoa Qu, multiple GM (Thunderbolt Ver.) were seen in action. One such unit, piloted by 2nd Lt. Bianca Carlyle, faced off against a MA-05 Bigro and destroyed it.



Notes and Trivia

  • The large backpack is inspired by modern day life support systems for spacesuits.
