1/100 MG PMX-003 The-O

The Gelgoog Cannon kit is essentially a color variation from the original MG Gelgoog kit, though it does contain one additional runner of parts -- those for the cannon backpack unit as well as the arm-mounted shield and gun unit. 

Some other minor details (such as the scribing pattern on the soles of the feet) also differ. Kit can be completed as either the B or C-model (i.e. two different backpack units are included).

Note that the kit is snap-assembly like all MG kits, but is molded in the gray and red color shown on the left, below.

The beige and gray variation at right would require painting.
