YMA-99 Thruster Gyan is the Booster Type Mobile Armor.
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-09 Dom and MS-09R Rick Dom mobile suits. A massive mobile armor created by combining the modified YMS-15 Gyan (late model) with "the fuselage of a battleship" and the MSN-09 Extra Blaster Zeong's Lazer Claws.
- Beam Rifle
A revolutionary weapon for it's time, the beam rifle is the primary weapon used by the Gundam. Making use of the Federations E-cap (or "energy capacitor") technology, the rifle uses charged concentrations of Minovsky particles as ammunition. This gives the beam rifle firepower equivalent to that of a battleship's beam cannons.
- There are two fire-linked mega particle guns mounted in the clawed, wire-guided legs of the mobile suit,.
- I-Field Genetator
When Minovsky particles are released into the air or into open space, the positive and negative particles spontaneously align themselves into a three-dimensional cubic lattice. Due to the repulsive and electrostatic forces between the Minovsky particles, this lattice functions as a kind of a force field, which is referred to as an I-field. This field has difficulty permeating conductive materials like metal, water, and plasma, and it exerts a repulsive force against mega particles.
