Core Gundam is the compact, transformable mobile suit from Gundam Build Divers Re:RISE that serves as the foundation for the Planet System. Piloted by Hiroto Kuga, the Core Gundam can combine with various support units (Planets) to adapt to different combat situations, making it one of the most versatile Gunpla in the Build Divers universe.

The Core Gundam features a small, agile design with excellent articulation and the ability to dock with Earthree Armor, Marsfour Armor, Veetwo Armor, Jupitive Armor, and Mercuone Armor. Each Planet configuration transforms the Core Gundam into a specialized combat unit with unique weapons and capabilities, from close combat to long-range support.

Popular HGBD:R releases include the Core Gundam with various Planet armor sets, allowing builders to create multiple configurations from a single base unit. These kits are perfect for builders who enjoy customization and the creative freedom of the Build Divers series.
