Bandai 1/100 MG Barbatos 4th Form

Mikazuki's ace in its 4th Form, the definitive 1/100 treatment

The Bandai 1/100 MG Gundam Barbatos 4th Form is the Master Grade kit of the ASW-G-08 Gundam Barbatos as it appears in its fourth configuration in Mobile Suit Gundam Iron-Blooded Orphans, piloted by Mikazuki Augus. This is the definitive 1/100 scale treatment of the Barbatos, built around a fully articulated inner frame with silver-plated cylinders, a spinning Ahab Reactor gimmick, and hip joints engineered specifically to recreate Barbatos's signature downward-looking combat pose. If you want the most detailed and poseable version of the Barbatos available, this is the kit to build.

Build difficulty

The MG Barbatos 4th Form is a snap-fit kit with a complete inner frame and interlocking armour attachment, and is better suited to builders who've completed at least one MG kit already. The silver-plated cylinder parts should be handled with care to avoid scratching the plating, and the inner frame assembly takes more patience than a standard HG. Independent builder feedback is genuinely mixed on how beginner-friendly the build is, covered honestly further down this page.

Technical highlights

The armour panels interlock directly with the inner frame rather than sitting over it, giving the Barbatos its characteristic layered mechanical look and full poseability without armour parts popping off mid-pose. The mace includes a sliding handle, the smoothbore gun has a slide-and-fold action, and three pairs of interchangeable hand parts let you set up a range of display configurations. Colour separation is strong straight off the runners; panel lining is worth doing to bring out the inner frame detail, but paint isn't required for a good result.

What makes this kit special

  • Silver-Plated Inner Frame Cylinders: the Gundam Frame includes silver-plated cylinder parts, a premium detail with more mechanical depth than the Full Mechanics or HG versions.
  • Spinning Ahab Reactor Gimmick: the chest Ahab Reactors rotate for the first time on an MG Barbatos, faithfully recreating the anime's signature reveal.
  • Dynamic Hip Joint Engineering: hip joint movement is specifically engineered to recreate Barbatos's famous downward-looking combat pose from the anime.
  • Interlocking Armour System: armour panels attach directly to and interlock with the inner frame, enabling full poseability while staying secure during display.
  • Full Three-Weapon Loadout: the mace with a sliding handle, the smoothbore gun with a slide-and-fold action, and the long sword all ship in the box.
  • Three Pairs of Interchangeable Hands: multiple hand configurations for weapon-holding, open and relaxed display poses.
  • 4th Form Configuration: specifically the Barbatos in its fourth form colours and loadout, distinct from the standard and Lupus variants.

Compatible accessories

The MG Barbatos 4th Form is a 1/100 MG scale kit. No display base is included with the kit. For dynamic mace and sword poses, pair the Barbatos 4th Form with the Bandai Action Base 4 - Display Stand for 1/100 Scale Gunpla, the standard 1/100 display stand.

Most of the IBO lineup is between restocks right now. The one exception is the Bandai SDBB Gundam Barbatos Lupus DX, a chibi-style take on Barbatos in its Lupus form (a different form to this 4th Form kit), if you want a fun-size add-on for the shelf while more Post Disaster stock lands.

Perfect for

Intermediate to advanced builders who've completed at least one MG kit and want to tackle the silver-plated inner frame and interlocking armour system. Iron-Blooded Orphans fans who want the most detailed and poseable 1/100 scale version of the Barbatos available. Builders who want genuine engineering gimmicks, the spinning Ahab Reactor and sliding mace handle set this apart from the Full Mechanics versions. Anyone who wants to recreate Barbatos's signature downward-looking combat pose with the engineered hip joint system. Not recommended as a first MG kit given the inner frame complexity and plated-parts handling.

Fast Australian shipping

Dispatched same day from Brisbane if ordered before 2pm AEST on weekdays. Free shipping Australia-wide on orders over $199. Packed securely in a sturdy outer box with water-soluble cornstarch void fill that dissolves cleanly in the sink.

What to watch for

A general web search plus a targeted Reddit and YouTube sweep found two genuine build blogs (kimithebuilderblog and madjesh.blogspot.com) with real, independently written build accounts, and they don't always agree, so both sides are worth knowing before you start. One reviewer found nub cleanup on some parts tough going, the other found the gates thin and easy to cut cleanly, so treat gate cleanup as something that varies by part rather than a fixed pattern. On beginner-friendliness the two reviewers land in different places too, one recommends other MG kits first and describes the upper body as fragile mid-pose, the other calls the manual's part markings clear enough for a confident beginner. Both independently note the kit stays stable on its feet despite the weight of its weapons, which is a genuine point in its favour once built. One reviewer also flagged the head piece as having no locking pegs, so a solid bump has a real chance of popping it loose, worth knowing before you hand it to a shelf full of curious housemates.

Build notes

Snap-fit, no glue required. Panel lining is recommended to bring out the inner frame detail. Silver-plated parts should be handled with care to avoid scratching. Action Base sold separately.

Assembly Guide

SKILL LEVEL REQUIRED
Skill Level.3. Basic modeling skills are essential. These kits are not recommended for beginners or children due to the high level of complexity of assembly and the sheer volume of parts. Experience in building more complex Gunpla models is recommended. Parental supervision is essential. A full set of hobby tools is recommended that includes, nippers, hobby knives, sandpaper, sanding sticks, files, buffing files, glues, tweezers, and decal adhesive/softener. Parts will need to be removed by using a pair of nippers and cutting the part away from the runner. Parts may require clean-up where they were removed from the runner.
No Cement Required

Gunpla (plastic model kits) are a snap together assembly and do not need plastic cement to complete. We always recommend having some plastic cement handy as a part of your modeler's tool kit. If you prefer to fix your model in a particular pose then plastic cement will work. Plastic cement is also perfect to use if a joint is loose. Apply plastic cement in a single thin layer and allow it to dry completely before test fitting. Re-apply more cement if necessary.

No Painting Required

Gunpla (plastic model kits) are designed to be built and displayed without the need for painting. Kits are molded in different colours replicating the colours of the actual mecha from the Mecha series. A technique called colour separation, where multiple parts of the model are molded in different colours on the same sprue is also used. Mecha kits often include stickers or water-slide decals that can be applied to the model to enhance its appearance. Some Gunpla kits come with pre-painted parts or parts with pre-applied details, such as metallic or translucent finishes.

Many modelers still choose to paint their kits to customize and add further detail. Painting allows for more creativity and personalization, enabling modelers to achieve unique effects, weathering, and colour schemes that may not be available out of the box. However, the kits are designed to be enjoyable and visually appealing even without painting, making them accessible to a wide range of hobbyists.

Frequently Asked Questions

How is the 4th Form different from the standard MG Barbatos or Barbatos Lupus?

The 4th Form is a distinct configuration from Iron-Blooded Orphans with its own colour scheme and weapon loadout (mace, long sword and smoothbore gun). It's a different silhouette to Barbatos Lupus or Lupus Rex, so if you're after this specific look, check the form name on the box before buying.

Is this a good first Master Grade kit?

It's better suited to builders who've completed at least one MG kit already. The silver-plated inner frame parts need careful handling to avoid scratching, and the full inner frame assembly takes more patience than a standard HG. Independent builder reviews are mixed on this exact point, some found the manual's part markings made it manageable for a confident beginner, others recommend starting with an easier MG first.

Does it need glue or paint?

It's a snap-fit kit, no glue required for the standard build. Panel lining is worth doing to bring out the inner frame detail once assembled, but paint isn't necessary to get a good result straight off the runners.

What weapons come in the box?

You get all three of Barbatos's signature weapons: the mace with a sliding handle gimmick, the smoothbore gun with a slide-and-fold action, and the long sword. Three pairs of interchangeable hands let you set up different grips for each.

Is a display stand included?

No stand ships in the box. The Bandai Action Base 4 (built for 1/100 scale) is the standard pairing if you want the mace or sword raised in a dynamic pose.

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.

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!
