Top 5 Gundam: IBO 1/100 Gunpla Kits for Building the Ultimate Post Disaster Collection

There is something different about building Iron-Blooded Orphans Gunpla kits in 1/100 scale, because the extra size makes the exposed frames, blunt weapons, long limbs, and raw mechanical shapes feel much more aggressive in person.

These are not mobile suits that need to look clean or heroic to be interesting, as they are at their best when they look like they have survived a bad fight and are already being sent into the next one.

That makes the IBO 1/100 lineup especially appealing, because both the older Full Mechanics kits and the newer Master Grade releases give these machines more room to show off the pistons, weapons, armor gaps, and physical combat focus that define the Post Disaster timeline.

The newer MG kits clearly offer the stronger building experience overall, but some of the Full Mechanics releases still matter because they cover important suits that have not yet had the same upgraded treatment.

Our top 5 Gundam IBO 1/100 Gunpla ranking focuses on kits that balance collection presence, build enjoyment, accessories, poseability, character, and how well each release captures the brutal close-range appeal of Iron-Blooded Orphans.

5. Full Mechanics 1/100 Gundam Bael

Gundam Bael earns a spot because it brings a very different kind of energy to an IBO 1/100 collection.

Piloted by McGillis Fareed, Bael is less about heavy equipment and more about status, history, and the weight of the Calamity War legend attached to Agnika Kaieru.

The Full Mechanics kit captures that feeling through its slim Gundam Frame build, wing binders, and twin Bael Swords, giving the finished model a cleaner and more ceremonial presence than most of the rougher Tekkadan machines.

That simplicity is both the kit’s biggest strength and its main limitation.

It does not have the weapon variety of Vidar, the monstrous proportions of Lupus Rex, or the polished engineering of the newer MG releases, but it still looks important the second it joins a collection.

The twin swords make posing easy to understand, while the wing binders give the suit enough visual movement to avoid looking too plain next to bulkier IBO kits.

Bael also matters because it represents one of the most important symbolic machines in the series, which gives it more value than a basic equipment list might suggest.

For builders who want an IBO 1/100 kit that feels legendary, focused, and tied directly to the political collapse running through the second season, Gundam Bael remains one of the stronger Full Mechanics picks.

4. Full Mechanics 1/100 Gundam Barbatos Lupus Rex

Gundam Barbatos Lupus Rex is the kind of kit that makes subtlety feel completely irrelevant.

This is Mikazuki Augus’s final Barbatos form, and everything about it feels more animalistic, more extreme, and more unsettling than the earlier versions of the suit.

The Full Mechanics kit benefits from the larger 1/100 scale because the long arms, clawed hands, tail blade, and super-large mace all need room to feel as intimidating as they do in the anime.

It is not as refined as the newer MG Barbatos kits, and builders who care most about inner-frame detail, plastic quality, and advanced articulation will notice that difference quickly.

Even so, Lupus Rex still earns its place because it captures the final form of Barbatos in a way that feels immediately powerful once assembled.

The huge mace is the main attraction, but the real appeal is how the whole model looks like it has moved beyond being a normal Gundam and turned into something much more feral.

That makes it an essential choice for IBO fans who want their collection to show the full path from Barbatos’s rough beginning to its most brutal final state.

For builders who value presence, character, and the raw final-battle feeling of Iron-Blooded Orphans, Full Mechanics Barbatos Lupus Rex is still hard to ignore.

3. MG 1/100 Gundam Barbatos

MG Gundam Barbatos is still one of the most important Iron-Blooded Orphans kits Bandai has released, because it proved the series could work beautifully in the Master Grade format.

This version focuses on Barbatos’s fourth form, the look most closely associated with the early identity of the series before Mikazuki’s machine becomes more extreme with each rebuild.

The MG kit stands out because the internal Gundam Frame is not just something hidden under armor, as it becomes a major part of the building experience and helps the finished model feel properly mechanical.

The exposed pistons, layered armor, mace, sword, smoothbore gun, and smaller detailing all give the kit a more satisfying physical presence than the older 1/100 Barbatos releases.

What makes MG Barbatos work so well is that it understands the original appeal of the suit without trying to turn it into a final-form monster.

It looks lean, adaptable, and dangerous in a way that fits the early Tekkadan story perfectly.

The build also feels like a strong entry point into IBO 1/100 kits, because it offers the modern MG experience while still keeping the mobile suit recognizable as the rough machine pulled back into battle by Mikazuki and Orga.

For builders who want one Barbatos kit that captures the start of the Iron-Blooded Orphans journey with the best overall engineering, MG Gundam Barbatos remains an easy recommendation.

2. MG 1/100 Gundam Vidar

MG Gundam Vidar is one of the strongest IBO 1/100 kits because it gives Gaelio Bauduin’s revenge suit the modern Master Grade treatment it always deserved.

Appearing in the second season of Iron-Blooded Orphans, Vidar carries a colder and more controlled presence than the Barbatos line, trading savage mace swings for sabers, handguns, a rifle, and hidden foot blades.

The MG kit makes that identity feel much sharper through the updated Gundam Frame, deployable Hunter’s Edge parts, handgun blowback gimmick, detachable rifle magazine, and Burst Saber parts.

Those details matter because Vidar is not supposed to feel like a bulky bruiser.

It should feel fast, precise, and quietly dangerous, and the MG version does a strong job of making that come through in both standing poses and action displays.

The blue armor, exposed frame sections, red thruster details, and blade-focused equipment help it stand apart from the more animalistic Barbatos kits without feeling any less important.

It also benefits from arriving after MG Barbatos, because the kit feels like Bandai had a better grasp on how to make the IBO Gundam Frame work in this format.

For builders who want a 1/100 Iron-Blooded Orphans kit with mystery, revenge, strong accessories, and a more polished modern build, MG Gundam Vidar comes extremely close to the top spot.

1. MG 1/100 Gundam Barbatos Lupus

MG Gundam Barbatos Lupus takes the number one spot because it feels like the best balance between the raw identity of Iron-Blooded Orphans and the upgraded build quality people expect from a modern Master Grade.

This is the version of Barbatos that shows Mikazuki’s machine becoming more aggressive without fully crossing into the beast-like extremity of Lupus Rex.

The MG kit makes that middle stage feel especially satisfying, using an updated Gundam Frame with improved shoulder movement and better waist motion to support the kind of wide, physical poses that Barbatos Lupus needs.

The Sword Mace, twin maces, forearm-mounted 200mm cannons, and sharper body proportions give the model a strong weapon-focused presence without making it feel overloaded.

What pushes it above the original MG Barbatos is that Lupus feels like the more complete expression of how Mikazuki fights by the second season.

It still has the lean Gundam Frame appeal of the earlier suit, but the longer limbs, heavier melee equipment, and more aggressive stance make it feel like Barbatos has evolved into something much more dangerous.

It also avoids some of the problems that can make the older Full Mechanics kits feel like compromises, because the MG treatment gives the suit stronger detail, better posing potential, and a more satisfying sense of structure during the build.

For fans who want one IBO 1/100 kit that feels current, character-driven, and powerful without going as extreme as Lupus Rex, MG Gundam Barbatos Lupus is the strongest choice.

It feels like the best all-around package in the current Iron-Blooded Orphans 1/100 range, combining Mikazuki’s most recognizable second-season machine with the kind of modern engineering that makes the build feel worth the larger scale.

An honorable mention should go to the Full Mechanics 1/100 Gundam Vidar for carrying the suit before the MG version existed.

The 1/100 Gundam Gusion/Gusion Rebake is also a strong option as it allows either mobile suit to be built using a shared frame.

The original 1/100 Gundam Barbatos 6th Form is worth considering too, especially for builders who like seeing the suit in one of its more armored first-season configurations.

In our view, MG Gundam Barbatos Lupus, MG Gundam Vidar, MG Gundam Barbatos, Full Mechanics Gundam Barbatos Lupus Rex, and Full Mechanics Gundam Bael represent the strongest overall 1/100 selection from Mobile Suit Gundam: Iron-Blooded Orphans.

Whether you are building around Tekkadan’s rough survival story, Gaelio’s revenge arc, McGillis’s obsession with legend, or the brutal close-range combat that makes IBO feel so different from other Gundam series, these five kits give you a 1/100 collection that feels varied, recognizable, and very easy to keep expanding.
