165. GX-9900 Gundam X

GX-9900 Gundam X (aka Gundam X, X) is a mass-produced MS built by the former United Nations Earth in After War Gundam X. There are two feature versions of Gundam X. The primary featured one was piloted by Garrod Ran and later to Jamil Neate. It was later badly damaged in combat and was repaired and rebuilt as GX-9900-DV Gundam X Divider.
The second one was featured in the manga sequel, After War Gundam X: Under the Moonlight. The story featured a different Gundam X (adorned with teal colors) and its pilot was Rick Aller.

Built at the height of MS advancement by the UNE, the GX-9900 series is one of the most advanced MS of its time. The series was mass-produced and pressed into service near the end of the 7th Space War. After the environmental devastation at the end of the 7th Space War, MS development on Earth became stagnant as humanity recovered; Gundam X and its brethren Gundam series remains top-of-the-line after 15 years. Because the UNE no longer existed, there was no regulation over the Gundams and they found second-life in the hands of the Vultures. It's because of Vulture-use that no two Gundam X is exactly alike. 

164. MSM-03 Gogg

MSM-03 Gogg is a mass produced amphibious mobile suit, it was first featured in Mobile Suit Gundam.

The Gogg was heavily armored to withstand deep sea pressure. The mobile suit also held a powerful reactor, so powerful that the Gogg could even use twin mega particle guns mounted in its body. The Gogg, however, had no cooling systems and used the water as a natural heat sink. Lastly, the MSM-03 Gogg had ballast tanks also built inside the body, allowing it to travel fully submerged. The tanks could also hold water to cool the mobile suit's reactors during out of water operations, but as soon as the water ran out, its reactor would overheat, forcing it back into the water.
The MSM-03 design proved marginally successful. However, it wasn't produced in a lot of numbers and was later replaced by more powerful and better designed amphibious mobile suits, such as the MIP Company's highly successful MSM-07 Z'Gok. The Gogg served as a base from which almost all other underwater combat mobile suits were designed.

163. Gundam MK-II (Titans Version) RX-178

The Gundam Mk II was made famous in the second anime series of the Gundam Franchise, Zeta Gundam. At the beginning of the series AEUG was interested in obtaining it after they learned it was being developed in one of the space colonies by the Titans paramilitary organization. With the reluctant help of NewType Kamille Bidan they were able to obtain more than one Gundam Mk II’s during their raid. His help and skill level also ensured his place as the pilot of the Gundam Mk II.

162. MS-09 Dom

MS-09 Dom is a mass-production ground combat mobile suit,the unit makes its first appearance in the anime series Mobile Suit Gundam. It is most well known to be piloted by the Black Tri-Stars, along with the pilots Abraham and Rayburn.

The MS-09 Dom was the successor to MS-06F Zaku II and MS-07B Gouf mobile suits, and far surpassed both in terms of performance. Developed as a heavy-type, high performance mobile suit, the Dom could outmaneuver the Federation's new mass production mobile suit, the RGM-79 GM. While the Dom can use many of the Zaku II and Gouf standard armaments, it was Typically equipped with a new 360mm Giant Bazooka, which could easily blow apart a mobile suit. Later, a new 880mm Raketen Bazooka was also developed that could destroy almost anything with one hit. The Dom also had a new Heat Saber, shaped very much like a beam saber, that was used for close combat. Lastly, the Dom featured a scattering beam gun, too weak to damage mobile suits, but powerful enough to blind a pilot for a few seconds.
The Dom's main advantages were its speed, agility, and maneuverability. The Dom had massive legs and a "skirt," under which were several high-powered thermonuclear jet engines that allowed the Dom to hover over the ground. These gave it a 240 kilometer per hour hovering speed, which far surpassed the Gouf's running speed of only 99 kilometers per hour. The Dom's superiority was blatantly evident to the Zeon forces and the Dom went quickly into mass production.

161. MS-07 Gouf

The MS-07 Gouf was a series of mobile suits produced by the Principality of Zeon during the One Year War. The Gouf is design as s a high-performance replacement for the MS-06J Zaku II Ground Type. The MS-07 Gouf first appears when Ramba Ral arrives on Earth to avenge the death of Garma Zabi. Ramba Ral and the Gouf proves to be a formidable foe for the White Base crew as it is far more powerful than the Zakus the crew have been fighting up until that point. The Gouf is armed with a 75 mm machine gun hand and "heat rod", which could be used as a superheated slicing weapon or as a grappling weapon with a powerful electric shock effect. It also has a powerful heat sword, an improved heat-based weapon from the Zaku's heat hawk. The Gouf could also use the standard Zaku II weapons, such as 120 mm machine gun or 280 mm bazooka. Amuro Ray in the Gundam eventually destroy Ramba Ral's Gouf, however the mobile suit soon becomes a mainstay of the Zeon ground forces. Shortly after the Gouf's introduction its production was halted in favor of the MS-09 Dom. However research into the Gouf's basic design would continue which would lead to the development of several improved models that would see limited production. Despite the research none of the Gouf's models would see development in the United Maintenance Plan that the Principality of Zeon initiated to improve existing mobile suit designs.

160. GEL GOOG MS-145

The MS-14 Gelgoog was a series of mobile suits produced by the Principality of Zeon during the final days of the One Year War and was the first Zeon produced mobile suit to carry beam weaponry. The suit was initially known as the MS-11 Gelgoog but the model number was eventually reassigned to the Action Zaku. The Gelgoog was designed as a high performance mobile suit equipped with beam weapons to counter the Earth Federation's RX-78-2 Gundam. As with the Zaku line of mobile suits, many variants of the Gelgoog were produced for different mission roles, such as support fire and sniping. During the OYW, the Gelgoog was initially tested by ace pilot Char Aznable, who piloted his own YMS-14S Gelgoog Commander Type for a short period of time. After further battles by Char and test piloting by Chimera Corps aces Johnny Ridden and Thomas Krutz, the Gelgoog was put into mass production as the MS-14A Gelgoog. However, despite being superior to any machine fielded by the Federation, with the exception of the various Gundam variants, when the unit was deployed at the Battle of A Baoa Qu most of these powerful machines were piloted by fresh and inexperienced recruits who were no match for the Federation's by then veteran mobile suit pilots. After the war, many Gelgoogs were either salvaged by Zeon remnants, captured by the Federation, or put on the market for civilian use. Between the years of U.C. 0088 and U.C. 0120 at least two Zeon remnant groups would take the Gelgoog's design and upgrade the mobile suit with modern technology of the time.

159. MSM-07 Z'Gok

The Z'Gok is a mobile suit created by the Principality of Zeon during the One Year War.

The Z'Gok's success came from what it learned from the Gogg's and Acguy's errors. The Z'Gok was very agile and fast in and out of water. MIP also replaced the bulky ballast water tanks used by the Gogg and Acguy for cooling off the mobile suit for out of water operations with an air cooling fan system. Notably, the weapon layouts were improved. Overall, the MSM-07 Z'Gok is considered the most successful amphibious mobile suit line produced by the Principality of Zeon during the One Year War.
Each of the Z'Gok's hands featured built-in mega particle cannons for easier and more precise aiming. Each hand also had three-claws which could be used to thrust into the Earth Federation's mobile suits or they could be used to smash things as well. The Z'Gok also had six 240 mm missile launchers built into the head with five rounds.

158. YMS-15 Gyan

The YMS-15 Gyan is a mobile suit from the anime series Mobile Suit Gundam.

Produced by the Zimmand Company, the YMS-15 Gyan was meant to be the rival to the Zeonic Company's MS-14 Gelgoog. The Gyan is meant to fight along side Zimmand's highly popular and powerful MS-09 Dom and MS-09R Rick Dom mobile suits.
The exotic YMS-15 Gyan was meant as a purely close-combat mobile suit with Zimmand's Doms providing the long-range support. The Gyan's primary weapon was a large and powerful beam sword. A support weapon was a large, circular shield that has 56 small missiles launchers built into it. The shield also holds a dozen hide bombs and space mines that are used to lay traps.
The appearance of the Gyan, with its silver armor and Pickelhaube helmet design the Gyan has a strong resemblance to a medieval armored knight.

157. RX-78GPO3S GUNDAM GPO3S

156. RX-78GP01 Gundam "Zephyranthes"

The RX-78GP01 Gundam "Zephyranthes" (aka Gundam Zephyranthes, GP01, Unit 1) is a mobile suit from Mobile Suit Gundam 0083: Stardust Memory. It is piloted by Kou Uraki.

As described in the MG model manual and MS encyclopedia, at the conclusion of the One Year War, the Federation opened the Gundam Development Project, aimed at creating mobile suits superior to those that Zeon had developed. The RX-78GP01 Gundam Zephyranthes was the first of three Gundam type mobile suit prototypes completed under this plan.
The RX-78GP01 was designed to be an adaptable mobile suit, able to operate under any condition on earth or in space; to that end its design is superficially similar to the other RX series Gundams. Unlike previous suits, this was one of the first to re-introduce the core fighter concept in its design, utilizing the recently developed FF-XII Core Fighter II as the cockpit. The RX-78GP01 was taken to Australia's Torrington Base for terrestrial testing, where it was commandeered by (and later assigned to) Federation ENS (later LTJG) Kou Uraki in his effort to retrieve the RX-78GP02A.

155. RX-77 Guncannon

The RX-77 Guncannon is a fictional mobile suit from Mobile Suit Gundam anime series, originally designed and illustrated by Kunio Okawara. One of earliest mecha designs in the Real Robot genre, Guncannon's concept of a heavily armored humanoid machine with dual shoulder cannon became the inspiration for various artillery fire-support mecha in other mecha anime and games. The Dankof from Blue Comet SPT Layzner (1985), Dragonar-2 from Metal Armor Dragonar (1987), Schutzwald from the Super Robot Taisen: Original Generation video game series, and other designs owe to the aesthetic of the Guncannon as inspiration for their designs.

146. Gihren Zabi

Gihren Zabi (ギレン・ザビ, Giren Zabi?, also spelled Giren) is a fictional character, and antagonist from the universe of the Gundam anime series. He was voiced by the veteran seiyu, Banjo Ginga in the original Japanese version. In the English dubbed series and movie adaptations the character was voiced by Hiro Kanagawa and Doug Stone respectively.

American Rock musician Andrew W.K. dubbed a famous speech of this character in his cover album Gundam Rock released during the 30th anniversary of the Gundam franchise.

144. LM314V21 Victory 2 Gundam.

LM312V04 Victory Gundam is the titular multi-mode tranformable mobile suit. It was featured in the anime Mobile Suit Victory Gundam. The unit was piloted by protagonist Uso Ewin, until he acquired its direct descendant, the LM314V21 Victory 2 Gundam.

Designed around a Core Fighter base, the Victory Gundam consisted of a "Top Fighter" and "Bottom Fighter", each of which could be separated and docked with a Core Fighter or operated via remote control from another Core Fighter. This modular/docking design not only increased the chances of pilot survivability, thus allowing a pilot to continue fighting if part of his mobile suit was damaged or destroyed, but also allowed for replacement of destroyed modules mid-battle if needed.
The LM312V04 Victory Gundam was the first mobile suit to incorporate the "Minovsky Flight" system, a miniaturized Minovsky craft system designed to keep the mobile suit hovering in mid-air at any altitude while maneuvering with its rocket and vernier thrusters. The Minovsky Flight technology would later serve as the basis for the LM314V21 Victory 2 Gundam's much more advanced "Minovsky Drive."
