Master Grade 1/100 Gundam

MG models were first introduced in the summer of 1995, designed and made to higher standards than most other models. These kits take much longer to construct and are often much more expensive than their lower-grade counterparts. More recent Master Grade plastic models typically feature a movable inner frame system that enables extensive movement and bending of joints, as well as including standing and seating miniature figures of the pilots of each Gundam model.

Beginning in 2005 with the Zeta Gundam, Older MG Kits would be redesigned under the Ver.2.0 moniker with features such as a full inner frame. The RX-78-2 Gundam has had multiple MG iterations, including a Ver.1.5 that uses a mix of old and new parts, and Ver.3.0 that is modeled after the life-size statue similar to the Real Grade version of the same robot.

Though the name "Master Grade" is widely known because of Gundam, it is not Gundam exclusive as a few Master Grade offerings have come from mechas in Patlabor and Dunbine. Bandai also released a line featuring a series of character figures from Dragon Ball Z, Kamen Rider, and Tiger & Bunny under the name MG Figurerise.

In 2002, a new line of Master Grade kits subtitled "Ver. Ka" was released, which was Master Grades designed by mecha designer Hajime Katoki. Mobile suits chose to become Ver. Ka kits are chosen by annual fan votes. In 2020 a new line, Master Grade Extreme (abbreviated as MGEX) was redesigned of Master Grades that contained additional gimmicks called "Extreme Points". The first model kit of this line is the Unicorn Gundam Ver. Ka contained a LED light strip that ran across the mobile suit, compared to Individual lights that had to be wired throughout the inner frame.
