The RX-78-6 Mudrock Gundam (sometimes spelled "Madrock", aka "Gundam G06") is a mobile suit from Kunio Okawara's M-MSV original design series. Its design was updated for Mobile Suit Gundam: Zeonic Front by Keiichiro Katagiri.

Technology & Combat Characteristics

Based off the combat data of the RX-78-2 Gundam, the RX-78-6 Mudrock Gundam was designed to address the biggest shortcoming in the former's design - a lack of weaponry once the Gundam's primary beam rifle was out of energy. To get around this limitation, the Mudrock was built as a sustained-combat unit with higher firepower.

It has a new beam rifle backed up by a pair of arm-mounted grenade launchers, and a pair of 300mm cannons inspired by the RX-77-2 Guncannon. To further increase the Mudrock's staying power, it has improved frontal armor, and also retained the Gundam's beam sabers and head vulcans. The added payload wound up increasing the suit's weight by roughly one-third. To prevent this from affecting the suit's mobility, the Mudrock had a reactor with higher output, an enlarged backpack, and the legs are fitted with movable thrusters.


  • 60mm Vulcan Gun
A pair of shell-firing armament built into the head. Low offensive power, only used to restrict enemy movement, and lay down a wall of suppressive fire due to their rapid fire capability.
  • Beam Saber
The beam saber is a small device held in the mobile suit's hands when deployed and is powered by a rechargeable energy capacitor. It emits high-energy Minovsky particles to form a blade-shaped I-field (via manipulation of electromagnetic fields), and then fills this I-field shell with superheated Minovsky particle plasma to produce an effective cutting blade. The Mudrock is equipped with two beam sabers stored beside the 300mm cannons when not in use.
  • 300mm Cannon
A pair of low recoil cannons equipped on the backpack.
  • Grenade Launcher
Equipped on both forearms. Each launcher carries 4 rounds for a total of 8.
  • XBR-M79X-C2 Beam Rifle
A beam rifle developed near the end of the One Year War to test the concept of making the energy CAP a cartridge to solve the problem of recharge time. It was not finished in time, forcing the Mudrock Gundam to use the same type of beam rifle as the Gundam Ground Type instead.
  • BLASH XBR-M-79E Beam Rifle
The same beam rifle as used by the Gundam Ground Type, it is a redesign of the RX-78-2 Gundam's XBR-M-79-07G beam rifle. Instead of the 79-07G’s large movable sensor, this rifle is fitted with the BP-SS-001 composite box-type sensor system utilized on the BR-M-79C-3 Beam Spray Gun and licensed from BOWA Corporation, granting the weapon improved targeting precision.
  • HWF GMG·MG79-90mm Bullpup Machine Gun
The bullpup machine gun was a system weapon developed as a Space/Ground dual use projectile weapon. Though compact, it has sufficient anti-MS firepower while maintaining accuracy. Its muzzle velocity is increased due to the use of new gunpowder and this enables it to easily penetrate the armor of Zeon's mobile suit. A box-like sensor system incorporating a video camera and laser sensor is installed at the top, and when this system is used alongside the Gundam's targeting system, target acquisition capability is enhanced.
  • Hyper Bazooka
A general purpose fire support rocket launcher platform for Mobile Suits. With considerable destructive power owing to the explosive yield in each warhead, the weapon was primarily used to destroy less-maneuverable battlefield targets such as warships, satellites, land battleships, bunkers, and buildings.
  • NFHI RGM-M-Sh-AGD Shield
A shield made of titanium/ceramic composite developed near the end of the One Year War. Thanks to its curved shape and an anti-beam coating with a higher heat resistance than previous models, it is more resistant against both ballistic and beam weapons. This shield is the same shield as used by the RGM-79G GM Command and RGM-79GS GM Command Space Type.
  • Hyper Hammer
An enhanced version of the gundam hammer. Like its predecessor, it is a large spiked ball attached to a chain. However, it also has several rockets mounted into the ball to allow it to maneuver more effectively as well as the ability to change its direction before impact, and to increase the damage it could cause.


The Mudrock was originally supposed to be launched into space and participate in the Operation Star One. However, the attack by the Zeon's Midnight Fenrir Corp special forces on Jaburo on November 30, 0079, caused Lieutenant Agar to pilot the incomplete Gundam Mudrock for the protection of the Pegasus-class ship SCV-73 Blanc Rival. Despite the Gundam's firepower, it was damaged along with the ship. Mudrock was later repaired and deployed in its completed form to assist in the recapture of the California Base. However, Agar once again found himself against the Midnight Fenrir, and in the ensuing battle, the Mudrock Gundam was severely damaged and forced to retire.

Notes & Trivia

  • In the novel Mobile Suit Gundam: Zeonic Front 0079, the backpack-mounted cannons are depicted as beam cannons, and it is said that they were unable to demonstrate proper performance because of a cooling system issue. Later, the output is reduced to 70% (still considered to be enough to destroy any Zeon mobile suit with a single hit), reducing the load on the power unit.
  • In the original Zeonic Front game, the Mudrock Gundam did not use its custom beam rifle from M-MSV, instead using the Gundam Ground Type beam rifle (or the RX-78-2 Gundam's beam rifle, for the playable version). However, in subsequent adaptations of the game, such as Mobile Suit Gundam Side Stories, it was usually depicted using the custom rifle.
  • The Mudrock's eyes were yellow in the original M-MSV design, red in Zeonic Front, and green in various other video game appearances, such as Gundam Side Stories. The HGUC Gunpla included both red and green stickers for the eyes.
  • Due to the lack of official artwork, how the Mudrock Gundam's grenade launchers work are depicted inconsistently. In Gundam Versus and Mobile Suit Gundam Side Stories, the entire front section of the grenade launcher flips open to reveal the muzzle. In Mobile Suit Gundam: Battle Operation 2, however, the grenade launcher pops up during use, similar to the Gatling guns used by the RX-78NT-1 Gundam "Alex".
  • Though it was not specified in the source material, the G Generation series, from Wars onwards, depicts the Mudrock Gundam as having magnet coating.
  • In G Generation Genesis, the Mudrock's cannons are depicted as solid shell weapons. However, since the Zeonic Front story in the game is based on the novelization, it is still shown firing beam cannons in cutscenes.
  • The M-MSV version of the Mudrock Gundam was said to be armed with Hyper Bazooka and Hyper Hammer. However, no artwork exist for these weapons, and they were not used for the Zeonic Front version.
