For many fans of Mobile Suit Gundam Wing, the OZ-07AMS Aries represents one of the most iconic grunt suits of the After Colony era. Its unique, bird-like silhouette and transforming capabilities make it a standout design among the mobile suits used by the Organization of the Zodiac (OZ). However, if you are currently scouring hobby shops or online retailers for an "HG Aries" or "Master Grade Aries" to build, you have likely encountered a frustrating reality.

Currently, Bandai has never released a standard, mass-produced plastic model kit (Gunpla) for the Aries.

Despite the recent expansion of the High Grade After Colony (HGAC) line, which has finally brought suits like the Leo, Maganac, and Deathscythe to modern standards, the Aries remains absent. This article explores why this kit is so elusive, how to avoid the common "Arios" confusion, and what alternatives exist for collectors who need this suit on their shelves.

The Common Mistake: Aries vs. Arios Gundam

When searching for a "Gundam Aries model kit," the search engines often prioritize results for the "Arios Gundam." It is crucial to understand that these are two entirely different machines from different timelines.

The Arios Gundam (GN-007) is a transformable mobile suit from Mobile Suit Gundam 00. It is a high-performance Gundam piloted by Allelujah Haptism. Because the names are phonetically similar, many beginner builders accidentally purchase the High Grade (HG) 1/144 Arios Gundam kit, only to realize it looks nothing like the airborne grunts from Gundam Wing.

The Aries (OZ-07AMS) is the aerial combat suit from Gundam Wing. It is a mass-produced unit characterized by its cylindrical legs, flight wings, and lack of a traditional Gundam face. If you are looking for the latter, do not buy any kit labeled "Gundam 00" or "Arios."

Why Isn't There a Standard Gunpla Aries?

It seems baffling that such a prominent suit from a popular series doesn't have a modern kit. To understand this, we have to look at the history of Bandai’s production and the engineering challenges of the Aries design.

The 1995 Non-Grade Era

During the original run of Gundam Wing in the mid-90s, Bandai produced a series of 1/144 "Non-Grade" kits. While they covered the main Gundams and some grunt units like the Leo and the Tallgeese (which were often 1/100 scale), the Aries was skipped entirely in favor of more "heroic" designs. At that time, grunt suits were not considered as marketable as they are today.

Engineering Complexity

The Aries features a highly specialized transformation. Unlike the Leo, which is a sturdy, bipedal suit, the Aries has legs that collapse and retract into the torso for flight mode. Translating this into a 1/144 scale plastic model kit requires either:

  1. Parts Swapping: Providing two sets of legs.
  2. Complex Articulation: Engineering thin, spindly joints that are strong enough to hold a pose but small enough to fit inside the armor.

For a budget-friendly High Grade kit, these engineering hurdles often make Bandai hesitant, especially when compared to the Leo, which is far simpler to manufacture and shares parts with many other variants.

The Grunt Suit Priority List

In the modern HGAC line, Bandai has focused on "standard" frames. The HGAC Leo was a massive success because it utilized a simple, effective joint system that allowed for easy assembly and army building. The Aries, being a flight-type unit with very few shared parts with the Leo, requires a completely new mold from the ground up, making it a more expensive investment for the manufacturer.

The Best Official Alternative: Robot Spirits Aries

Since there is no buildable kit, the "Robot Spirits" (Side MS) Aries is the gold standard for collectors. Released under Bandai's finished action figure line, this is not a kit—it comes pre-assembled and painted.

Features of the Robot Spirits Version

The Robot Spirits Aries was released in two versions: the standard black/olive drab version and the white Noin custom version.

  • Articulation: This figure handles the transformation perfectly. The legs collapse as they do in the anime, and the wings are fully articulated.
  • Accessories: It typically includes the Chain Rifle, the Missile Pods, and interchangeable hands.
  • Scale: While not explicitly labeled as 1/144, it scales very well with modern HGAC model kits, standing at roughly the same height as an HGAC Leo.

The Downside

Because this is a discontinued collector's item, it is no longer available at retail prices. You will likely have to search secondary markets. Prices for a mint-in-box Robot Spirits Aries have climbed significantly over the years, often costing three to four times the price of a standard HG kit.

How to Get an Aries Through Custom Building

For hobbyists who refuse to buy a pre-made figure and insist on the experience of building, there are several "pro" routes to obtaining an Aries.

1. Resin Garage Kits

In the late 90s and early 2000s, companies like B-Club (a subsidiary of Bandai) released resin garage kits for the Aries.

  • Difficulty: These are for expert modelers. Resin requires cleaning, sanding with a respirator, and using super glue (cyanoacrylate) rather than plastic cement.
  • Availability: These are extremely rare and usually found only on Japanese auction sites.

2. 3D Printed Conversion Kits

With the rise of high-resolution resin 3D printing, the Gunpla community has taken matters into its own hands. Several independent designers have created "Aries Conversion Kits."

  • How it works: You usually buy an HGAC Leo as a "base frame." You then discard the Leo's outer armor and replace it with 3D-printed Aries parts (head, torso, wings, and legs).
  • The Experience: This is currently the most popular way to get a modern-looking Aries. It allows you to use the excellent articulation of the modern Leo frame while achieving the Aries aesthetic.

3. Scratch Building and Kitbashing

Some master-level builders choose to scratch-build an Aries using plasticard (styrene sheets) and parts from other kits. Common "donor" kits for an Aries kitbash include:

  • HGBC Sky High Wings: For the flight pack.
  • HGUC Asshimar: For some of the rounded structural components.
  • HGAC Leo: For the internal frame and arm joints.

Does the HGAC Leo Success Mean an Aries Is Coming?

There is a strong reason for optimism in the Gunpla community. When Bandai released the HGAC Leo in 2018, it utilized the "Fine Build" system, which prioritized ease of assembly. This kit sold incredibly well, leading to the release of the HGAC Maganac (another grunt suit) and the P-Bandai exclusive Leo variants.

Bandai has shown a renewed interest in the Gundam Wing "After Colony" timeline. With the recent releases of the HGAC Vayeate and Mercurius, it is clear that they are willing to produce more niche OZ mobile suits. The Aries is consistently near the top of fan polls for "Most Wanted HG Kits."

However, if it does happen, it is highly likely to be a Premium Bandai (P-Bandai) release. Because the Aries is a grunt suit with a complex mold, Bandai may prefer a limited production run to ensure they meet the specific demand of hardcore fans without overstocking general retail shelves.

What to Look for When Buying a Used Aries

If you decide to hunt for an old resin kit or a Robot Spirits figure, keep these tips in mind to ensure you aren't getting a bootleg or a broken product:

  • Check the Logo: Genuine Bandai products will have the blue or red Bandai "Spirits" logo. Be wary of listings that use generic terms like "Robot Fighter" or "Aries Style."
  • Joint Integrity: The Robot Spirits Aries is known for having somewhat thin joints in the leg-collapsing mechanism. If buying used, ask the seller if the joints can still hold the weight of the suit in flight mode.
  • Scale Accuracy: If a listing claims to be an "1/100 Aries," it is almost certainly a custom-built or 3D-printed item, as no official 1/100 version exists.

How to Prepare for an Aries Build

If you are planning to go the 3D-printed conversion route, you should prepare your toolkit accordingly.

  • Resin Safety: If your parts are 3D-printed resin, ensure you wash them in isopropyl alcohol and cure them under UV light if the seller hasn't already.
  • Primer is Key: Resin parts and plastic parts have different textures. To make the kit look uniform, a high-quality primer (like Mr. Surfacer 1000) is essential before painting.
  • Color Matching: The classic Aries olive drab can be replicated using Tamiya AS-6 (Olive Drab) or Mr. Color 304. For the Noin custom, a pure semi-gloss white is standard.

Summary for Collectors

The search for a Gundam Aries model kit is a journey of managing expectations. While the "Arios" from Gundam 00 is easy to find, the true OZ-07AMS Aries from Gundam Wing requires a bit more effort to acquire.

  • For the builder: Look for 3D-printed conversion kits that utilize the HGAC Leo frame.
  • For the collector: Save up for the Robot Spirits (Side MS) Aries action figure.
  • For the hopeful: Keep an eye on P-Bandai announcements, as the success of the HGAC line makes an official release more possible than ever before.

FAQ: Frequently Asked Questions about the Aries Kit

Is there an Master Grade (MG) Aries?

No, there is no official Master Grade Aries. The only 1/100 scale Aries units in existence are high-end custom scratch-builds or very rare vintage resin kits.

Can I use the HGAC Leo parts to make an Aries?

Yes, the HGAC Leo serves as an excellent "inner frame" donor for custom Aries projects. The arm and thigh joints are particularly useful, though the outer armor and the unique "bird" legs must be sourced elsewhere or custom-made.

Why do I see "Bandai Aries" on sites like AliExpress?

Be extremely cautious. These are often either mislabeled Arios kits or "third-party" (bootleg) 3D prints of questionable quality. Official Bandai plastic model kits are almost always sold through reputable hobby retailers like HobbyLink Japan, P-Bandai, or local authorized dealers.

What is the difference between the Green and White Aries?

In the Gundam Wing anime, the green (olive drab) units are standard mass-production models used by OZ soldiers. The white units are typically associated with Lucrezia Noin and her special task forces. Mechanically, they are identical, though collectors often prefer the white version for its cleaner aesthetic.

Will Bandai ever release an HGAC Aries?

While not officially confirmed, the Aries is a prime candidate for a future HGAC release. The community demand is high, and Bandai has been systematically filling the gaps in the Gundam Wing roster. However, expect it to be a P-Bandai exclusive due to the unique tooling required.

Conclusion

The absence of an official Gundam Aries model kit remains one of the great mysteries of the Gunpla world. As a staple of the Gundam Wing series, it deserves a modern HGAC treatment. Until Bandai decides to engineers those complex folding legs for a mass-market release, fans must rely on the excellent Robot Spirits figure or the creative world of 3D printing and kitbashing. By understanding the difference between the Aries and the Arios and knowing where to look for high-quality alternatives, you can still add this classic flight suit to your After Colony collection.
