For over four decades, Bandai has continuously pushed the boundaries of plastic modeling, captivating hobbyists of all ages. This article traces the rich history of Gundam model kits, from the humble beginnings to the cutting-edge releases of today, and explores how this hobby became a global cultural phenomenon.
Whether you're a seasoned builder or new to the hobby, understanding the history of gunpla provides a deeper appreciation for the kits you build. From the iconic RX-78-2 to the latest MGEX releases, each era brought innovations that changed the way we build and display our favorite mobile suits. Join us as we journey through the evolution of Gundam plastic models.
The Birth of Gunpla: 1980-1989
The story begins in July 1980 when Bandai released the first Gundam model kit: the 1/144 scale RX-78-2 Gundam. This kit was revolutionary for its time, featuring snap-fit assembly and pre-colored plastic, making it accessible to children and adults alike. Unlike traditional model kits that required glue and paint, these early gunpla could be built right out of the box, a concept that would define the hobby.
Throughout the 1980s, Bandai expanded the lineup with various scales, including 1/100 and 1/60, and introduced the iconic 'High Grade' (HG) line in 1990. The 1980s also saw the rise of the 'Old Grade' (no-grade) kits, which lacked the articulation and detail of modern kits but captured the hearts of a generation. These early kits laid the foundation for the intricate engineering we see today.

- Introduction of snap-fit assembly
- Pre-colored plastic eliminated the need for painting
The High Grade Revolution: 1990-1999
The 1990s marked a turning point with the introduction of the High Grade (HG) line in 1990. These kits featured improved articulation, better color separation, and more detailed panel lines, setting a new standard for gunpla. The HGUC (High Grade Universal Century) sub-line, launched in 1999, focused on mobile suits from the Universal Century timeline and became immensely popular.
This decade also saw the release of the Master Grade (MG) line in 1995, which brought 1/100 scale kits with inner frames, advanced articulation, and a level of detail previously unseen. The MG RX-78-2 Gundam Ver. 1.0 was a game-changer, featuring a fully articulated inner frame that allowed for dynamic poses. These innovations solidified Bandai's reputation as a leader in plastic modeling.

- MG line debuted in 1995 with inner frames
- HGUC sub-line focused on Universal Century suits
The Perfect Grade and Beyond: 2000-2009
The new millennium brought the Perfect Grade (PG) line in 2000, which pushed the boundaries of scale and detail. The PG RX-78-2 Gundam was a masterpiece, featuring a complete inner frame, LED units, and over 400 parts. This line represented the pinnacle of gunpla engineering, offering an unparalleled building experience.
In 2002, Bandai introduced the Real Grade (RG) line, which packed Master Grade-level detail into a 1/144 scale. The RG RX-78-2 Gundam featured a pre-assembled inner frame, advanced articulation, and incredible surface detail. This decade also saw the rise of the 'Gunpla Builders' phenomenon, with custom builds and dioramas becoming increasingly popular. The hobby was no longer just about assembly; it was about creativity and self-expression.

- RG line debuted in 2002 with pre-assembled inner frames
- Rise of custom builds and dioramas
Modern Era: 2010-Present
The 2010s saw the introduction of the High Grade Universal Century (HGUC) Revive line, which remade classic kits with modern engineering. The MGEX (Master Grade Extreme) line, launched in 2020, represented the ultimate expression of Master Grade, with the MGEX Strike Freedom Gundam featuring a stunning gold-plated inner frame and intricate detail. This kit became an instant classic among collectors.
Today, gunpla continues to evolve with new technologies like 3D printing and advanced injection molding. Third-party manufacturers have also entered the scene, offering unique takes on classic designs. For instance, the DABAN PG Gundam Unleashed RX-78-2 Model Kit provides an affordable alternative to the Bandai original, while the Menghu 1/100 00 Raiser MB Style Model Kit offers a stylized version of the popular 00 Raiser. These kits demonstrate the diversity and creativity that define the modern gunpla landscape.

As we look to the future, the possibilities for gunpla are endless. From the intricate MG HWS Expansion Set for Hi Nu Gundam Ver. Ka to the innovative Kosmos Colorful RGB LED Units for MG Gundam Vidar, there is something for every builder. Whether you prefer the authenticity of Bandai kits or the unique offerings from third-party brands, the world of gunpla has never been more exciting.
