Straight build.

Back in 2004, when the HGUC Psycho Gundamcame out, a lot of us old-school fans — myself included — were absolutely thrilled. The legendary giant Gundam was finally getting a proper HG release!! And then the Mk-II, which seemed like it would follow right away, took a whopping 21 years to actually show up. But it arrived as a kit that's been upgraded by just as many years as that long wait. (The price has been upgraded too, mind you — from ¥5,000 to ¥10,000, a clean 2x increase..)

Actually, back in 2023 when the Build Metaverse HG series HG Typhoeus Gundam Chimerawas released, this kit was already teased — it included a runner labeled "Psycho Gundam Mk-II." The arm section had nearly the same structure as the Psycho Gundam Mk-II, so that runner was actually used before this kit even came out.

First off, the Mk-II had a far more complex design than the original Psycho Gundam to begin with. The biggest highlight of this kit is probably its "perfect" color separation. Being a large kit, all of its flashy coloring has been fully broken down into separate parts. In particular, all the yellow verniers and red accent pieces are achieved purely through parts separation — no stickers needed. Thanks to that, the parts are nice and chunky, the color combinations look great, and there's a real satisfying feel to snapping all those colorful pieces together. The build quality also has that smooth, crisp click you'd expect from a modern HGUC kit.

Second, given the size of this kit, joint stability was a concern going in — but overall stability has been tuned to "perfection" as well. Large kits can sometimes have major joints pop out due to their size and weight, but this kit uses locking pin connections at five key points: the head, waist, shoulders, hip joints, and shield mount. As you can see in the early photos in the review above, you rotate the pin 90 or 180 degrees to insert it, then rotate it back to lock it in place. Thanks to this, the joints absolutely will not come apart no matter what pose you put it in — aerial poses included.

On top of that, the basic joint strength itself is solid, so despite the big frame there's no looseness whatsoever. And yet for a polycap-less kit, the movement feels surprisingly smooth — in short, both articulation feel and stability issues have been fully resolved. That said, as expected, the transformation gimmick means articulation is below average, so dynamic poses are pretty much out of the question. The ankles in particular are very restrictive, so don't get your hopes up for any leg-based poses.

The transformation gimmick is also well-designed and lives up to expectations. Above all, you can clearly see a lot of care went into the stability, and it holds together solidly even after transforming into Mobile Armor mode. The transformation process is a bit complex and tough to figure out without the manual, but that just goes to show how carefully it's been tuned. The HGUC Psycho Gundam's transformation gimmick wasn't bad either, but the Mk-II — coming 21 years later — is a significant step up.

For weapons, you get a large shield, reflector bits, and beam parts. The reflector bits come in both stored and deployed versions, 10 of each, and the stored versions can actually be stowed in the backpack. The 12 beam parts can be used as beam sword and beam cannon effect parts, and together with wire leads they can be used to recreate the wire-guided psycommu beam swords and beam cannons. As a bonus, a clear Action Base 4 and small stands are included, which can be used with the main unit and the bit weapons. That said, Action Base 4 is a bit too flimsy to support this massive kit — it can hold both MS and MA modes, but it wobbles around and feels pretty unstable.

So after all the waiting from longtime fans, the Psycho Gundam Mk-II has finally gotten the HGUC treatment. It's come out as a high-quality large kit with excellent color separation, solid stability, a well-executed transformation gimmick, and an impressively big frame. Articulation is something you shouldn't expect much from, though — understandable given the intricate transformation gimmick. Either way, it's sure to be a great gift for the longtime fans who've been waiting for this kit, and it's also a big, beautiful kit I'd happily recommend to newer fans who dig the style. :-)
