Master Grade is a line of Gundam plastic model kits(Gunpla) with a scale of 1/100. The Master Grade line of kits was first introduced in 1995. Master Grade kits details, articulation, and proportions are only surpassed by the Perfect Grade kits.
In 2002, mecha designer Hajime Katoki redesigned various gundam mobile suit kits under the label "Ver Ka (Verison Katoki)." If a Mobile Suit kit was either updated or redesigned, a label was added to the name such as "VER 1.5", "Ver 2.0", Ver 3.0" and "Ver RM" to differentiate them from the previous gundam kit.
