MS-14A Gelgoog

The MS-14A Gelgoog was a high efficiency general purpose mobile suit mass produced by the Principality of Zeon.


After the Earth Federation‘s deployment of the RX-78-2 Gundam during the One Year War, Zeon responded by changing its mobile suit development plans. Work on the high performance mobile suit MS-11 Gelgoog was abruptly cancelled. Zeon wanted its new mobile suits to be able to equip handheld beam armaments. The model number MS-11 was reassigned to the Act Zaku from the Pezun Project.

The Gelgoog project was rebooted under the model number MS-14 and it led to the development of the experimental YMS-14S Gelgoog Commander Type. Thirty units were produced and they were deployed in October UC 0079. Twenty-nine units were assigned to Zeon’s elite Ace Corps in the Corregidor Shoal Zone for field testing. The beam rifle technology proved to be successful and the Gelgoog Commander Type was optimised for mass production as the MS-14A Gelgoog.

The Gelgoog was quickly put into production and deployed to the front lines. However, only 165 units were ever produced when the war ended on 31 December UC 0079. The Gelgoog was introduced too late in the war. It was mostly assigned to novice pilots who were no match for the Federation veterans, despite the latter piloting the less advanced RGM-79 GM.


The MS-14A Gelgoog was developed together with energy cap-based armaments to fulfil Zeon’s goal of arming its new mobile suits with handheld beam weaponry. It was meant to be a replacement for the outdated MS-06F Zaku II as the backbone of the Zeon forces.

The Gelgoog was a high performance mobile suit that matched the Earth Federation‘s RX-78-2 Gundam. It was actually faster, had a power plant higher output, and was armed with more beam weaponry. Its superiority was evident during the first clash between the two units during the One Year War.

The forearms of the Gelgoog were mounted with jet engine thrusters to increase the mobile suit’s manoeuvrability. Some units were later refitted with linear seats and panoramic monitor cockpits.


The standard weapons used by the Gelgoog were a ranged beam weapon and a twin beam sword for melee combat.

Twin beam sword

The twin beam sword was a melee weapon designed for the Gelgoog. It had a long handle that gave it with a greater reach. The sword had beam emitters on both ends. It could be used with a single blade as a halberd or with dual blades. This gave it greater flexibility during close-ranged combat.

It was stored in a recharging dock on the back of the Gelgoog when not in use.

Beam rifle

The beam rifle fired concentrated mega particles drawn from rechargeable energy caps. The energy caps allowed the rifle to discharge beams without having to draw power from a nuclear reactor.

The Gelgoog could equip a large shield for increased protection. It was noticeably larger compared to the shields used by earlier mobile suits.
