Master Grade (MG) The 1/100 scale Gunpla plastic model kits of the Action Figure Mobile Suits in the Gundam meta series. The series produced in 1995 as part of the Gundam 15th Anniversary project.
Master Grade kits are unique from other 1/100 scale Gunpla plastic model action figure kits with their level of detail, articulation, and proportions just under the Perfect Grade line. A majority of the kits feature a skeletal inner frame with working hydraulics and some also accommodate Gunpla LED Units for light-up the figure. To give viewers a perspective of the Action Figure Mobile Suit's size, many MG plastic model kits come with 1/100 scale figure of the pilots or key characters of their respective series; in addition, some kits include 1/20 scale character figures.
