Master Grade (MG) (マスターグレード Masutā Gurēdo?) is a line of 1/100 scale Gunpla kits of the Mobile Suits in the Gundam meta series. The series was first produced in 1995 as part of the Gundam 15th Anniversary project. Master Grade kits differ from other 1/100 scale Gunpla, with their level of detail, articulation, and proportions being second only to the Perfect Grade line. A majority of MG kits feature a skeletal inner frame with working hydraulics, some also accommodate Gunpla LED Units for light-up gimmicks. To give viewers a perspective of the Mobile Suit’s size, many MG kits come with 1/100 scale figurines of the pilots or key characters of their respective series. In addition, some kits include 1/20 scale character figures. Beginning in 2002, veteran mecha designer Hajime Katoki began redesigning various Mobile Suits and releasing them in the Master Grade line under the label of “Ver.Ka” (Version Katoki). Some of the Ver.Ka kits were produced as a result of annual fan votes. In addition, many Mobile Suits from the Universal Century and Cosmic Era timelines have received redesigns under the monikers “Ver.1.5”, “Ver.2.0”, “Ver.3.0”, and “Ver.RM”. Aside from the Gundam franchise, the Master Grade line has hosted other mecha anime series such as Aura Battler Dunbine and Mobile Police Patlabor. The line also has a spin-off line called Master Grade Figurise, which focuses on character kits for anime titles such as Dragon Ball Z, One Piece, and Tiger & Bunny, as well as tokusatsu titles such as Kamen Rider.
