5069182 - Bandai 1/144 Option Parts Set Gunpla 18 (Build Booster Set)

The Bandai 5069182 – 1/144 Option Parts Set Gunpla 18 (Build Booster Set) is a High Grade Build Custom accessory kit designed to expand customization options for 1/144 scale Gunpla, especially from the Gundam Build Fighters / Build Divers series.

This set focuses on the iconic Build Booster and Build Booster Mk-II, two transformable support units originally used with the Build Strike Gundam. Each unit can switch between a flight mode and backpack/support mode, allowing you to change your Gunpla’s silhouette and mobility depending on your build style.

Built using Bandai’s snap-fit system, the parts are molded for easy assembly with no glue required. The included 3mm joint compatibility system means the boosters can attach to a wide variety of HG kits beyond their original pairing, making them extremely flexible for kitbash projects.

Key features include:

• Two support units: Build Booster + Build Booster Mk-II
• Transformation between fighter and backpack modes
• Detachable parts that can be used as handheld weapons
• Universal 1/144 HG compatibility via joint adapters

The Build Booster Mk-II adds a slightly upgraded design with improved detailing and a more modern mechanical aesthetic compared to the original version, while still maintaining the same modular concept. Both units can be displayed separately, combined with other kits, or used purely as weapon/prop modules.

This set is especially popular among builders who enjoy custom loadouts, flight-capable Gundams, and Build Fighters-style creativity, since it lets you dramatically change a kit’s silhouette without permanent modification.

Overall, the Bandai HG Option Parts Set Gunpla 18 (Build Booster Set) is a versatile customization pack that enhances display value, adds dynamic flight gimmicks, and gives builders more freedom to create unique 1/144 scale configurations.
