The RX-78-Z1 Zeon's Gundam is a mobile suit that first appears in the game Mobile Suit Gundam Gihren's Greed. It also appears in the Mobile Suit Gundam: Gihren's Ambition video game.

Technology & Combat Characteristics

In a parallel timeline where Zeon won the One Year War, Zeon's Gundam was constructed from the design plans of the RX-78-2 Gundam taken from the Earth Federation (Although it is unclear how these designs were obtained, GAMES MSV suggests that they were found in Jaburo's factories). Although identical in appearance to the RX-78-2 (except for its green Zeon paint scheme and an MS-14A Gelgoog's shield in place of the RX-M-SH-008/S-01025 Shield), its interior mechanisms were completely revamped and featured parts derived from Zeon technology. However, despite these modifications, there were no significant changes to the machine's performance.


  • 60mm Vulcan Gun
Mounted in the head, these shell firing weapons have a high-rate of fire but little power and can't damage the thick armor of a mobile suit, though they can damage lightly armored areas such as the sensors. They are ideal for shooting down small, lightly armored targets such as missiles, attack vehicles, etc.
  • Beam Saber
The beam saber is a small cylindrical device held in the mobile suit's hands when operated and is powered by a rechargeable energy capacitor. The beam saber is capable of cutting through any metal not treated with anti-beam coating. The RX-78-Z1 is equipped with two beam sabers stored in the backpack.
  • Beam Rifle
A revolutionary weapon for its time, the beam rifle is the primary weapon used by the RX-78-Z1. Making use of E-cap (or "energy capacitor") technology, the rifle uses charged concentrations of Minovsky particles as ammunition. This gives the beam rifle firepower equivalent to that of a battleship's beam cannons. As the Minovsky particles destroy matter on a molecular scale, the beam rifle can penetrate even the thickest armor and destroy its target with a single shot. A weakness of the beam rifle is that it could only be fired 16 times before depleting its energy and becoming useless.
  • Shield
A basic arm-mounted defense armament for many mobile suits. The shield is a thick sheet of armor designed to take severe punishment that would normally destroy a mobile suit. Since the introduction of beam weaponry, shield is treated with an anti-beam coating to withstand several beam shots before the coating wears off. Typically, physical shield can only take so much damage before it succumb to the pressure and break. The RX-78-Z1 equips the same shield as the MS-14A Gelgoog.


This event takes place during the storyline of the game Federation vs Zeon.
During the last weeks of the One Year War, the focus of the war effort shifted to outer space. Despite this many Zeon soldiers and mobile suit units continued to operate on Earth. One such Zeon mobile suit team was successful in their ambush of a Medea supply unit and their capture of an RX-78-2 Gundam unit. The captured unit was re-designated RX-78-Z1, repainted in the standard Green Zeon colors and was subsequently used against the Federation a number of times to great effect. For some time, the Gundam wreaked havoc amongst Earth Federation forces on Earth until a Federation Special Forces Combat Unit was able to intercept the stolen Gundam in New Yark and destroy it. Despite the victory for the Federation unit, the stolen Gundam shot down nearly two dozen RGM-79[G] GM Ground Type and RX-79[G] Gundam Ground Type units before it was destroyed.
