A certain anticipation builds when a foundational figure in a collection hints at its true, unbridled potential. The upcoming METAL BUILD Gundam Barbatos, a piece many of us have keenly awaited, now shows its complete vision. This is it.
This product is the METAL BUILD Gundam Barbatos Expansion Weapon Set. BANDAI SPIRITS, through its TAMASHII NATIONS division, will release it in August 2026 for 16,500 Japanese Yen (appx. $106 USD). It provides additional armaments. They enhance the separately sold METAL BUILD Gundam Barbatos.
The Art of Evolution: Washio’s Vision in Three Dimensions
Naochiro Washio’s reinterpretation of Barbatos for METAL BUILD already impressed on the main figure, setting a new standard for mechanical fidelity and dynamic presence. This expansion diligently continues that design ethos, bringing an an even higher density of intricate detail and pushing the form further into new, unseen iterations. It’s a profound study in how a mobile suit can evolve. This is Washio’s vision. The fluent interplay between sharp angles, robust armor plating, and newly sculpted elements truly showcases a 2D concept brought to life with undeniable sculptural authority.

The Original Masterpiece: 460mm Rifled Cannon
The undeniable centerpiece here is Naochiro Washio’s original 460mm Rifled Cannon, a colossal piece of hardware that screams aggressive, high-performance engineering. This massive armament extends a full 28 centimeters (appx. 11 inches), anchoring securely to Barbatos’s rear waist via an integrated fuel tank and a pair of substantial mechanical arms. Its impressive scale is matched by its intricate detail. Every curve matters. From the giant, precision-crafted barrel to the defensive shield and large thrusters nestled at its aft end, it’s all there. Crucially, the thoughtful alloy construction within its pivot points ensures stable, dynamic posing, allowing Barbatos to wield this formidable payload in dramatic, high-speed thrust stances without ever feeling precarious.


Echoes of “Interlude”: Modified Thrusters and Melee
Beyond the colossal cannon, this set faithfully recreates crucial components from the ‘Modified Gundam Barbatos,’ a powerful form glimpsed in the captivating ten-year anniversary short ‘Interlude.’ We’re getting revamped waist thrusters, carefully styled to match the distinctive METAL BUILD aesthetic and reflecting the suit’s unique retro-thrust capabilities for truly dynamic combat maneuvers. Additionally, the Divaz-supplied tachi and kotachi blades round out a suite of elegant yet brutal melee options. These are vital. This inclusion is a direct nod to the mobile suit’s savage close-quarters combat style and its continuous, almost organic, adaptation throughout its brutal, resource-driven history.

Completing the Barbatos Saga
This expansion isn’t just a collection of parts; it’s the culmination of Barbatos’s evolving combat profile within the METAL BUILD framework. It offers collectors the unique opportunity to configure the Gundam Barbatos in multiple definitive forms, from its most iconic to its most obscure. The synergy between anime director Tatsuyuki Nagai’s narrative insights and Naochiro Washio’s mechanical genius shines through, making this set an indispensable piece for enthusiasts who value narrative depth alongside premium craftsmanship. This set is indispensable. It truly broadens the potential for display and storytelling in one’s collection.
The Collector’s Survival Guide: How to Justify This
The Collector Math: This expansion adds nearly half a foot of original Naochiro Washio design to the METAL BUILD Barbatos. That’s significant. Considering the sheer volume and alloy componentry in the 460mm Rifled Cannon, 16,500 JPY is a justifiable premium for future display presence.
How to tell your wife: Honey, remember how the METAL BUILD Barbatos already came with new weapons? This 460mm Rifled Cannon completes it, adding a totally unique design from the original artist, so it won’t even look like anything else. It’s art, really.
How to tell your parents: This isn’t just a toy; it’s a piece of industrial design, overseen by the original mechanical designer Naochiro Washio himself. It shows incredible craft. You’re essentially acquiring a physical concept piece that showcases a mobile suit’s potential evolution, right down to the tiny alloy joints in the cannon.
How to tell your kids: Listen, this big new cannon, the 460mm Rifled Cannon, makes Barbatos fly super fast and hit super hard. It’s super powerful. You can look at the sharp swords, but you absolutely cannot touch them.
This METAL BUILD expansion isn’t merely more accessories; it’s an extension of Barbatos’s narrative and mechanical lore, rendered with the series’ characteristic robust design. It feels complete. For those who already appreciate the raw energy of the Barbatos figure, this set offers the satisfaction of witnessing its full, brutal potential realized.
