The RX-93 ν Gundam Metal Structure Returns — Why Collectors Still Pay $3,000 for the 2019 Original

Welcome to one of the most detailed Gundam collectibles Bandai has ever made. One thing up front: the Metal Structure Kaitai-Shou-Ki is a pre-assembled, painted die-cast figure from Bandai's Tamashii Nations line, not a model kit you build. At P-Rex Hobby, a Bandai Recommended Store, we've been tracking this product across three release windows and three secondary-market price tiers — so when collectors ask us "is the Metal Structure Kaitai-Shou-Ki actually worth it?", we have data to back the answer.

After the 2019 original sold out within days, secondary-market prices for the Metal Structure Kaitai-Shou-Ki RX-93 ν Gundam have run far above the original retail price. Bandai reissued it in 2023. Now, for the third time, this 1/60-scale tribute to the Nu Gundam from "Mobile Suit Gundam: Char's Counterattack" is back. Pre-order closes May 21, 2026.

This guide breaks down what makes this kit different from any other Gundam product, why it commands four-figure secondary prices, and whether you should pre-order or wait.

What "Kaitai-Shou-Ki" Actually Means (and Why Bandai Built This Way)

The Japanese phrase 解体匠機 (Kaitai-Shou-Ki) literally translates to "deconstruction master craft" or "building by disassembling." It's Bandai's deliberate engineering philosophy for their Metal Structure line — and it's the opposite of how a normal Gunpla model kit works.

In a standard High Grade, Master Grade, or even Perfect Grade kit, the goal is clean exterior assembly — armor pieces snap onto an internal frame, hiding the engineering inside. With the Metal Structure line, Bandai inverts that approach. The armor is designed to open in stages, revealing the die-cast metal inner skeleton and mechanical detail underneath. The "completed" model isn't the one with all panels closed — it's the one where the engineering itself becomes the display.

That's why the Kaitai-Shou-Ki line is sold as a finished collectible rather than a model kit: it is an engineering exhibition piece. It's the closest thing to seeing how Bandai's industrial designers actually think about a mobile suit's interior, frozen at 1/60 scale.

The Nu Gundam's Place in "Char's Counterattack" Lore

For Universal Century fans, the RX-93 ν Gundam is the suit Amuro Ray pilots in the 1988 film "Mobile Suit Gundam: Char's Counterattack" — the closing chapter of the Amuro vs. Char rivalry that began with the original 1979 series. The film takes place in UC 0093, and the Nu Gundam represents the technological peak of Earth Federation mobile suit design at that point in the timeline.

Two things make the Nu Gundam iconic for collectors:

1. The Fin Funnels — psycho-frame remote weapons that float around the suit, controlled telepathically by Amuro's Newtype abilities. Visually, they're one of the most recognizable silhouettes in the entire Gundam franchise.
2. The psycho-frame finale — the Nu Gundam's psycho-frame resonates with the Sazabi's at the climax, generating enough force to push the Axis asteroid away from Earth. Whether you read it as miracle or mass psychic event, it's the emotional close of the original Universal Century arc.

Bandai has produced the Nu Gundam in nearly every grade — RG, MG, MG Ver.Ka, PG Unleashed, Robot Spirits — but the Metal Structure Kaitai-Shou-Ki is the only version that treats the suit as an engineering subject rather than a posable display.

1/60 Scale Die-Cast: How This Compares to PG, MG, and RG

Here's how the Metal Structure stacks up against other Nu Gundam kits available at P-Rex Hobby:

Kit	Scale	Parts	Inner frame	Build difficulty	Approx. CAD price
RG Nu Gundam	1/144	~280	Plastic Advanced MS Joint	Intermediate	$90
MG Ver.Ka Nu Gundam	1/100	~470	Full plastic frame	Advanced	$150
PG Unleashed Nu Gundam	1/60	~700	Plastic + LED ready	Expert	$400
Metal Structure Kaitai-Shou-Ki	1/60	Pre-assembled	Die-cast metal	None (finished figure)	See product page

A few things stand out:

• It arrives fully assembled and painted — unlike every other entry in this table, there is nothing to build.
• The inner frame is genuine die-cast metal, not engineering plastic. This adds physical heft, structural rigidity, and the visual weight that the Kaitai-Shou-Ki "engineering display" approach demands.
• The 370mm height is in the same range as a PG, but the box weight (and shipping cost) reflects the metal content.

This isn't an upgrade over a PG. It's a different category of object.

Three Releases (2019, 2023, 2026)

Bandai has released this exact figure three times:

2019 — Original release

• Released December 21, 2019 at about ¥93,000 JPY

2023 — First reissue

• Reissued in Japan in 2023

2026 — Third release (pre-order open)

• Japan price ¥132,000 (tax included), Japan release August 2026
• P-Rex Hobby: see the product page for current price and availability
• This is the only version available at MSRP right now. The 2019 and 2023 boxes are only obtainable through the secondary market, with no warranty and no reissue parts support.

For collectors who missed 2019 and 2023, this is genuinely the third — and likely final — chance to buy this model from a verified retailer at MSRP.

What's Included in the Box

The Metal Structure Kaitai-Shou-Ki RX-93 ν Gundam is a complete display package, not just the suit:

• Beam rifle, hyper bazooka, and twin beam sabers with effect parts
• Illuminated display base with built-in LED lighting
• Maintenance figures (the engineers, scaled to 1/60)
• Amuro Ray pilot figure in flight suit, also at 1/60 scale
• Full set of armor panels designed to open in stages
• Die-cast metal inner frame

One important caveat: The Fin Funnels are sold separately as a Bandai option set. This was true in 2019, 2023, and remains true for the 2026 release. Plan accordingly if you want the complete iconic silhouette.

Display Considerations Before You Pre-Order

This isn't a kit you can casually slot onto a typical Gunpla shelf. At 370 mm tall (≈14.6 inches) with the display base, the assembled Metal Structure occupies a significant footprint — comparable to a high-end Prime 1 Studio statue rather than a standard Master Grade kit.

Three things to plan for:

• Shelf depth: the diorama base is roughly 350 mm × 350 mm. Standard IKEA Detolf cabinets accommodate this; thinner display cases may not.
• Lighting: the included display base has built-in LED illumination, but the metal internals reward additional spot lighting. Many collectors pair this kit with an under-cabinet LED strip.
• Weight: the die-cast metal inner frame makes this kit substantially heavier than its plastic counterparts. Ensure your shelf or display surface is rated for the load — a fully assembled unit including base is in the 4–5 kg range.

For collectors building toward a dedicated Universal Century display shelf, this kit is a natural centerpiece — but it earns the spotlight rather than blends in.

Pre-Order Window and Release Date

P-Rex Hobby's pre-order is open until May 21, 2026. Bandai's general release is September 15, 2026, with our shipment expected to arrive in November 2026 based on standard transit from Japan. As a Bandai Recommended Store, we ship across Canada and the US, and pre-order positions at MSRP are first-come-first-served .

A few practical notes for first-time pre-order customers:

• No charge until ship date — your card is authorized but not charged at pre-order time
• Shipping calculated at checkout based on destination — Canada and US
• Cancellation policy: see our Pre-Order Policy for the full terms

Should You Pre-Order This — Or Hunt Secondary Market?

The math is unusually clean for this kit:

Path	Cost (CAD equiv.)	Risk	Warranty
Pre-order at P-Rex (2026)	See product page	Bandai delays possible	✅ Full retailer warranty
eBay 2023 reissue	Varies (above retail)	Box condition varies; auction sniping needed	❌ As-is
eBay 2019 original	Varies (above retail)	Most boxes opened/built; sealed mint extremely rare	❌ As-is

The verdict for most collectors: pre-order. The 2026 release is the only path that gets you a sealed, warranty-backed box at MSRP, with no auction stress. If you specifically want a 2019 or 2023 box for collector reasons, the secondary market is the only option — but expect to pay a premium for that distinction.

If you've ever looked at the Nu Gundam and wished there was a version that showed Bandai's industrial-design thinking instead of just the finished armor look, this is the one. It's not a casual purchase — it's an engineering exhibit at 1/60 scale, and at the price point of a high-end statue. That's why collectors keep paying well above retail for the 2019 box even when alternatives exist: there's no other product that does what this one does.
