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

Technology & Combat Characteristics

Produced by the Zimmad 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 alongside Zimmad's highly popular and powerful MS-09B Dom and MS-09R Rick Dom mobile suits.

The exotic YMS-15 Gyan was meant as a purely close-combat mobile suit with Zimmad's Doms providing the long-range support. The Gyan's primary weapon was a large and powerful beam sword. Its support weapon was a large, circular shield that has 60 needle missile launchers and also holds 25 hide bombs (space mines) which are used to lay traps for intended targets.

The appearance of the Gyan, with its silver armor and Pickelhaube helmet design, has a strong resemblance to a medieval armored knight. This is further emphasized by M'Quve's fighting style in it, which is heavily based on fencing.


  • Beam Sword
Gyan's primary weapon, the beam sword has a higher output than the Earth Federation Forces' beam sabers, and is specialized for slashing and piercing/stabbing attack.[1] Resembling a medieval knight's sword, the beam sword use Minovsky particles held in place by an I-Field to form an effective cutting surface that can slice through nearly any material.
  • Missile Shield
The Gyan is equipped with a large circular shield that not only defend it from beam weapons, but also has offensive capabilities in the form of needle missiles and hide bombs stored within. However, the storing of weapons does lower the shield's defensive capabilities, making it weaker than other standard mobile suit-use shields.[1]
  • Needle Missile
The missile shield stores 60 needle missiles.[1] Due to their small size, the needle missiles are not very powerful and are mainly used to restrain enemy's movement or for intimidation purposes.[1] These missiles can however still be quite deadly when fired in massed volleys.
  • Hide Bomb
A type of space mine (space version of the naval mine), 25 of them are stored in the missile shield.[1] The hide bombs freely floats around in space once deployed, damaging any Mobile Suit that come near them.


As the One Year War of the Universal Century raged on, the Principality of Zeon was in the process of developing newer and more powerful next-generation mobile suits through both their own research and development efforts and that of their major mobile suit manufacturers. The YMS-Gyan was the Zimmad Company's entry and production was supervised by Zeon's Col. M'Quve, who took one of the three prototype units as his own personal mobile suit.

M'Quve took his Gyan and used it as part of a plan to destroy the Earth Federation's advanced RX-78-2 Gundam. The plan was to lure the Gundam into Side 5's Loum Shoal Zone, specifically to the abandoned Texas colony, where M'Quve used the hide bombs and space mines to lay a series of traps. However, these traps proved inadequate and M'Quve was forced to take the Gyan directly into combat with the Gundam.

This would be the first and only time the Gyan saw combat. Against the Earth Federation's RX-78-2 Gundam, both the Gyan was destroyed and M'Quve was killed. The Zeon forces later sided with the Zeonic Company's more powerful, and beam weapon equipped, MS-14 Gelgoog.

Alternate History

In the Mobile Suit Gundam compilation movie, which was released after the anime, the YMS-15 Gyan is edited out. In the manga Mobile Suit Gundam: Char's Deleted Affair: Portrait Of Young Comet M'Quve and the Gyan are seen (indicating its events are based on the movie and not the anime) during the Battle of A Baoa Qu. Knowing of Kycilia Zabi's death, though not knowing the details, M'Quve saw the fortress as lost. He set into motion an evacuation plan for the wife of Dozle Zabi, Zenna Zabi and her daughter Mineva Lao Zabi. While a Gelgoog piloted by Char and a Gwazine-class acted as a distraction, M'Quve used the Gyan to escort a booster-equipped Komusai shuttle that held the Zabi family members. However the Gyan was caught in a last minute attack from a Magellan and subsequently destroyed.


A customized Gyan Gunpla built and operated by Tateo Sazaki, it has a metallic silver and dark gray color scheme with some red on its torso and missile shield. It retains the standard armament of the Gyan.

    • No. In fact, Gyan gunpla sold out from most store soon after GBF's first episode.
