MS-14S Gelgoog Commander Type

The MS-14S Gelgoog Commander Type is a tuned up version of the mass production MS-14A Gelgoog.

When the plans for the new MS-14 Gelgoog were completed, 30 prototypes, under the designation YMS-14S (the 'Y' in YMS-14S means it is a prototype Mobile Suit) were produced; 29 of the machines were given to the Chimera Corps, AKA the Ace Pilot Corps. The remaining unit was assigned to Char Aznable, who piloted it against Amuro Ray's RX-78-2 Gundam in two sorties. Later on in the war, the designation "Y" in YMS-14S was removed, renaming it MS-14S Gelgoog Commander Type. Originally a prototype, it was later converted into a Command Unit's High Performance Mobile Suit.

Featuring a high-powered generator, various thrusters to aid mobility, a large oval-shaped shield, a Beam Rifle, and a Beam Naginata, the MS-14S Gelgoog Commander Type rivals the capabilities of the Earth Federation's RX-78-2 Gundam piloted by Amuro Ray. In fact, the power generator, Beam Rifle, and Beam Naginata features a higher output than the RX-78-2 Gundam. Its speed and mobility exceeds even the RX-78-2 Gundam, as proven by Char during his first sortie in his MS-14S Gelgoog Commander Type with Amuro Ray's RX-78-2 Gundam during the One Year War. On the other hand, it has thinner and less durable armor than the Gundam (which is built with luna titanium alloy), and the lack of built-in weapons makes the Gelgoog easier to disarm (which Amuro literally did) and leave weaponless.

Proving to be an excellent design, the Zeon forces only made slight changes based on feedback from the test pilots. A significant change was adding more armour to make it more durable, but cutting down some of the Gelgoog's speed. Once finalized, they decided to put it under mass production to counter the Earth Federation's mass-produced RGM-79s, which were slowly but steadily pushing deeper into the Principility of Zeon's territories. The mass-produced version was then designated MS-14A Gelgoog.
