Bandai 1/144 Option Parts Set Gunpla 10 (Galaxy Booster)

The Galaxy Booster is the backpack support unit from the Build Strike Galaxy Cosmos, sold separately as a Gunpla option parts set. Twelve wings, each independently articulated, so you can shape the silhouette from a tight display profile to a full wingspan action pose.

Snap-fit, no cement and no paint needed. A dedicated display pedestal is included so the booster can stand on its own as a support-unit display piece.

What's in the box

  • Galaxy Booster unit with 12 articulated wings
  • Joint parts, one set

Compatible kits

Officially the backpack unit of the HGBF Build Strike Galaxy Cosmos. The joint parts use the standard HG 1/144 connection points, so the booster also attaches to a range of other HG-series Gundam kits for a custom loadout.

Build Fighters Series

Frequently Asked Questions

What is the central theme of the "Build Fighters" series?

"Gundam Build Fighters" is set in a world where Gunpla battling has become a globally celebrated sport. Unlike traditional Gundam series focused on war and politics, "Build Fighters" centers on friendly competitions, creativity in Gunpla design, and the bond between builders and their creations.

Who are the main protagonists in "Build Fighters"?

The series follows Sei Iori, a skilled Gunpla builder, and Reiji, a mysterious ally. Together, they participate in the World Tournament with Sei's custom-built Gunpla, aiming for the title of world champion while forging bonds with fellow competitors.

How do Gunpla battles function in this timeline?

In the "Build Fighters" world, participants use a Plavsky Particle System to animate their Gunpla, enabling them to engage in combat. The battles test both the quality of the model's construction and the builder's strategy, reflecting real-world model-building precision and imaginative play.

Are there any notable mobile suits from "Build Fighters"?

While many suits are reimagined versions of iconic models from various Gundam series, there are standout originals like the Build Strike Gundam (Sei's primary Gunpla) and the Star Build Strike Gundam, recognized for their unique modifications and combat capabilities.

How does "Build Fighters" enrich the broader Gundam narrative?

"Build Fighters" brings a refreshing spin, spotlighting the fandom's love for Gunpla building. It emphasizes camaraderie, creativity, and the joy of sharing a hobby, making it a heartwarming addition to the Gundam franchise, especially for model enthusiasts.

Amazing Build, my Grandson loved it!

Awesome kit, great extras. Only criticism is that the kit comes with a base so you don't need the second one. The kit also doesn't have the ability to take the blue LED bonus so if you don't have another use for it it is wasted. Luckily, I'm a Gundam tragic so will always have uses for extra bases and lighting kits.

Excellent service and fast delivery

I purchased on 6 Jan and my order arrived on 13 Jan. It was very well packed, with both boxes in excellent condition. Cam even provided a small free gift in the box! Overall purchasing experience was smooth and hassle-free. I haven’t had the chance to build the kit yet, but based on the service and care taken with shipping, I would happily purchase from this store if there are other Space Battleship Yamato models available.

Very rare with fair price

If you were one of the lucky ones that were able to travel to Sydney Gundam Base pop-up in 2025 and queued extremely early (like the first 40 or so) on the first day, probably you were able to grab one of these. Otherwise, the only alternative I would know of is traveling to Japan and being uber lucky of having it still being sold at Gundam bases. Otherwise, it's a second-hand market, and prices will go up. That said, the price was fair, I think it would be similar price as using a dropship service from Japan, with the exception that it's much faster and way more guaranteed you will get proper merchandise. So, Mecha Express, Cam, thank you so much for your store!
