The YMS-15 Gyan is a mobile suit from the anime series Mobile Suit Gundam
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. 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 was meant to fight along side Zimmand's highly popular and powerful mobile suit the MS-09 Dom and MS-09R Rick Dom. The Gyan's production was supervised Zeon's Captain M'Quve, who took one of the three prototype units as his own personal mobile suit. The Gyan has a head which bears a resemblance to the Pickelhaube helmet used by officers of the German Armed Forces during World War I and feet that look like the chain-mail used by medieval knights.
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 had 56 missiles launchers built into it. The shield also held a dozen hide bombs and space mines. However, the Gyan only saw combat once, against the Earth Federation's RX-78-2 Gundam, in which it and Captain M'Quve were both destroyed. The Zeon forces later sided with the Zeonic Company's more powerful, and beam weapon useable, MS-14 Gelgoog.
MS-15K Gyan KaiDespite being a rejected design, Gyan's development was continued after the war's end at asteroid base Axis as the MS-15K Gyan Kai ("kai" "改" is the Japanese word for "modified"). The Gyan Kai armed with shield similar to its predecessor and an improved beam sword which can be used as metal lance. The Gyan Kai actually has higher performance than some of Neo Zeon new mobile suit such as the AMX-107 Bawoo, but the difficulty of controlling it and its focus on melee combat prevent it from mass production. While this upgraded model never saw combat, its design inspired the Neo Zeon's prototype AMX-104 R-Jarja. In the popular video game Giren's Greed, the player can choose to develop the Gyan instead of the Gelgoog. This results in several variant Gyans, paralleling the Gelgoogs seen in later entries to the Gundam series: the MS-15B High Mobility Gyan, MS-15C Gyan Cannon, MS-15F Gyan Marine and MS-15Kg Gyan Krieger
