41,800 yen, with reservations opening August 3

The Tamashii Web product page lists it at a manufacturer’s suggested retail price of 41,800 yen, tax included. The reservation period is shown as starting August 3, 2026, with release scheduled for March 2027.

The official available sales regions shown include Japan, Asia, USA, EMEA, and LATAM. Depending on where readers order, local distributor preorders, overseas shop shipping costs, exchange rates, and cancellation terms may vary, so it is worth checking the final total and retailer conditions before payment.

Beginner-friendly points are the brother robot set and transformations

As the product name suggests, this is a 50th anniversary set that includes both Daitetsujin 17 and One Eight. The official description says it can recreate both brother showdown scenes and joint battle scenes.

Daitetsujin 17 can transform into fortress mode and flight mode, while One Eight can be put into flight mode by swapping the unit on its back. Rather than a simple standing figure, it feels closer to a finished robot toy built around transformation and scene changes.

The Gravition Unit handles the sound and light gimmicks

The official page explains that when the Gravition Unit is attached to the abdomen, voice and light-up features become available. It says combinations of abdominal buttons change the eye lighting, and the special-move Gravition voice is also recreated.

The set also includes Saburocker, Sigcon Jet, and Sigcon Tank. Each robot stands about 180 mm tall, and the materials are listed as ABS, die-cast, and PVC, making this a set where collectors should also consider display case space and battery preparation.

Why we picked it as tonight’s main candidate

Around 21:10 KST, we also checked figures related to Blue Archive’s Saori and Noa, PLAMATEA Al Azif, FGO Moon Cancer/Octo, and lines connected to NIKKE and Azur Lane. But for GX-101S, the official product page confirmed the price, reservation start date, release month, included parts, gimmicks, and available sales regions all in one place.

The image set also flows from the main hero cut to the brother robot display, fortress mode, flight mode, Gravition Unit, and One Eight components, making it a strong evening robot toy topic that helps beginners understand the appeal of this line within a single article.
