High Grade (HG) (ハイグレード Hai Gurēdo?) is a line of Gunpla kits of the Mobile Suits from the Universal Century timeline in the Gundam meta series. The first variation of the HG line, it was introduced in 1990 to celebrate the 10th anniversary of Gunpla, featuring the first four main Gundams in 1/144 scale redesigned with the latest molding technology at the time.[1] Improvements include snap-fit assembly, polycaps for the joints, clear plastic for the eyes, System Injection (a molding process where two or more colors are injected in one runner or part to minimize the need to use paint), and gimmicks not found in the original kits. Each kit includes an instruction booklet with artwork by Kunio Okawara and Hajime Katoki, who contributed to the redesign of the kits in this line.

Modelers in Japan refer to this line as "Old HG" (旧HG Kyū HG?) to distinguish it from the more recent HG lines.


HG # Model Series Yen Price Release Date Notes
RX-78 "Gundam" Mobile Suit Gundam ¥1,000 1990 March

The first HG kit ever released. Uses "MS Joint 2", a polycap-based skeletal frame for the upper torso and legs. Includes a transformable FF-X7 Core Fighter and features a functional Core Block System.

Was given a "Last Shot" final reissue in 2001 March before Bandai permanently discontinued it in favor of HGUC-021. As a result, this kit is highly sought after by collectors, fetching as much as over 10 times its original price.

The original mold is currently on display at The Gundam Base Tokyo.

  • This series introduced the format that would later be used as the standard HGUC box packaging: Black background, MS name printed in Compacta font with a colored square before it, and a gold stripe on the side panels.
  • The MS Joint system introduced in this series would later on become the basis for inner frame technology used in Perfect Grade, Master Grade, and Real Grade kits.
  • The G-Saviour Space Mode was designed with an inner frame and detachable armor pieces, as other variants such as the G-SAVIOUR G-Saviour Terrain Mode were planned for release. However, due to the poor reception of the G-Saviour film, the HG G-Saviour line was cancelled.
