The Gyan is an advanced
mobile suit developed by the Zimmad Company, as a competitor to
the Gelgoog created by its rival Zeonic. The Zeonic Company had
begun development of its powerful MS-14 Gelgoog line, and in response,
Zimmad Company designed its own next-generation mobile suit. Code-named
the YMS-15 Gyan, Zimmad's latest entry was intended to complement
its already-well-performing MS-09R Rick Dom space combat suits.
The Gyan's development was supervised by Zeon's Colonel M'quve,
and he took one of the three YMS-15 prototypes built as his personal
mobile suit and used it to battle the RX-78 Gundam at the Texas
Colony.
With Rick Doms to provide
the heavy long-range firepower, the Gyan was built with close
combat in mind. Like the Gelgoog, the Gyan is equipped with beam
weapons - but since it's designed primarily for close-range combat
against enemy mobile suits, its main weapon is a powerful beam
saber. The Gyan's only long-range weapons are the missiles and
space mines stored inside its unique shield, and it lacks the
Gelgoog's ability to use a beam rifle. Despite its high performance
as a close combat unit, the Zeon military favored the more well-rounded
Gelgoog - particularly since the Gelgoog incorporated the long-range
firepower the Gyan lacked - and the Gyan project was dropped.
