The YMS-15 Gyan was a prototype general purpose mobile suit designed by the Principality of Zeon. The “Y” in the model code denotes that it was an experimental prototype, while the “MS” refers to it being a mobile suit. The “15” in the model code indicates that it was the fifteenth design.
The Principality of Zeon developed the YMS-15 Gyan late in the One Year War. The Zeon military ramped up the development of high-performance mobile suits to regain the upperhand in the war. The Zeonic Company was getting positive results from its experimental unit, the YMS-14 Gelgoog. The Zimmad Company responded with the YMS-15 Gyan.
Only three Gyan units were produced. Lieutenant Colonel M’quve oversaw the development of the Gyan and used one unit as his personal mobile suit. It was deployed at the Texas Colony of Side 5 and he engaged the RX-78-2 Gundam in a duel that he subsequently lost.
The Gyan was designed to complement the long-range fire power of the successful MS-09R Rick Dom. Hence, it was built to excel in close combat. The Zeon military chose to mass produce the Gelgoog as it performed well in ranged and melee combat. That signalled the end of the Gyan project.
The Principality of Zeon needed a high-performance mobile suit to replace its aging army. The YMS-15 Gyan was designed as a melee combat counterpart to the successful long-range models, the MS-09 Dom and MS-09R Rick Dom.
The Gyan was built solely for close combat, with some projectile weapons for defense. The lack of ranged weapons provided it with better mobility. However, its weakness in ranged combat meant that it had to be backed up by a ranged unit to be effective in battle. This was cruelly exposed when the Gyan faced the Earth Federation prototype RX-78-2 Gundam in a one-on-one combat.
The Gyan was equipped with missiles for ranged combat and a melee weapon.
The Gyan had a beam sabre for melee combat.
The beam sabre used an I-field to contain Minovsky particles within the shape of a blade. Minovsky particles broke down matter at a molecular level. This meant that the beam sabre could cut through almost any material.
Minovsky particles were channelled into the sabre through an E-cap attached to its hilt. The E-cap recharged with Minvosky particles from the Gyan’s reactor when the sabre was stored in the dock.
The Gyan was equipped with a large circular shield that it used to defend itself from beam weaponry. The shield was mounted with projectile weapons to give the mobile suit some ranged fire power.
The shield could be mounted with a missile launcher that fired 56 rounds. These allowed the Gyan to deal a serious damage to its opponents during close combat.
Hide bombs and space mines
Depending on the nature of the mission, the shield could be armed with hide bombs or space mines. These were used as traps that the Gyan’s pilot would lure the enemies to.
