Just for fun, I detached the self-propelled nozzles and displayed them like fin funnels.
Of course, the self-propelled nozzles are just propulsion equipment in the original story, so they can't actually function like fin funnels.
If they had attacked like that in the source material, Hathaway probably would've died from PTSD shock..
(only those who've seen the original will get this)

ALYZEUS EQUIPMENT

To add the Alyzeus armor to the mass-production Nu Gundam, first swap out the beam saber mount on the backpack.

Orient the beam sabers forward in cannon configuration, fold the head antennae to the center, then

Open the chest mount and pull out the lower front skirt section to expose the attachment point.

Remove the legs, then open the cover to expose the mounting holes.

Insert the mass-production Nu Gundam's legs into the Alyzeus leg armor, then attach the leg armor.

Slot the legs into the Alyzeus-specific hip joint parts, then fit the upper body on top.

HGUC Alyzeus - Attach the Alyzeus front skirt. Due to the structure, this front skirt tends to pop off easily, which is a bit

Using separate joint parts, attach the self-propelled nozzles to the sides of the backpack and raise the shoulders upward.

Add joint parts to the sides of the shoulders, then attach the Alyzeus arms into the square slots on top.

At this point, make sure the Alyzeus arms are also double-locked into the holes on the backpack.

Once you attach the long chest armor, the Alyzeus equipment is fully installed.

FLIGHT FORM

Raise the nose, fold the large antenna, then lower the nose back down.

Detach the self-propelled nozzles and arms, then

Extend the stabilizers rearward and lift the rear skirt slightly.

Fold the rear skirt inward as shown.

Fold the feet as shown.

Rotate the inner knee armor as shown.

Fold the entire legs rearward, then add the auxiliary parts to the stand to secure the shin armor.

Rotate the missile containers at the hand positions as shown, then

Raise the shoulder armor upward in stages.

Then arrange the arm section into the configuration shown.

Straight build

The Alyzeus from "Mobile Suit Gundam: Hathaway's Flash — The Witch of Kyrke" has been released as an HGUC kit. Honestly, when I first saw the design sheets, I thought this was something they never intended to make into a plastic model — the shape is just that complex. But here it is, released alongside the 2026 film as an HGUC, and with the sculpt done really properly at that.

First off, it comes in a massive box on par with the HGUC Psycho Gundam Mk-II, packed full with no fewer than 39 runners. The build volume is on par with a high-end MG. On top of that, the mass-production Nu Gundam is included inside as per the lore, so it feels like two kits bundled into one. The build process is lengthy, but it has that satisfying Bandai feel to it, and there's a real joy in watching it come together like LEGO. That said, the design is as complex as it looks, and the panel lining points are record-breaking in number. In my case, panel lining alone took 4–5 hours — it's a lot of work, but the payoff once it's done is absolutely worth it.

The mass-production Nu Gundam inside appears to be on completely separate runners, so it'll probably get a standalone release down the line. Being an all-new tooling, it's cleanly executed with the latest technology. That said, while the shoulders and side skirts have excellent color separation, the chest, forearms, and beam rifle are handled with seals — and due to the seal material and design, they look really out of place, which has been drawing a lot of criticism since launch. It's somewhat fortunate that these areas are mostly hidden once the Alyzeus armor is on, but it's one of those occasional lapses in effort from Bandai.

Also, ten hands are included, but there are only two sets of hand armor, so you have to swap them around. I've seen cases where one or two hand armor pieces were missing, but this is the first time I've seen them just completely leave out a whole set. For the price of this kit, it's a really disappointing oversight. Setting aside those two annoyances, the mass-production Nu Gundam kit itself is actually quite good. It looks great, the articulation and joint strength are solid, and posing is easy. The backpack also supports three self-propelled nozzles, so you can give it a silhouette similar to the Nu Gundam, just like in the show.

The armor for Alyzeus — easily the most complex we've ever seen — turned out better than expected in terms of quality. The intricate design is brought to life with excellent three-dimensionality. Normally you'd worry about durability with something this complicated, but aside from the front skirt, everything locks together really solidly. The legs, torso, stabilizers, and all those thrusters hold their angles perfectly. The one issue, as mentioned above, is that the front skirt tends to pop off due to its structure — I think I reattached it about 30 times while taking review photos, but since everything else holds so well, it's somehow forgivable.

The transformation into Flight Form is far more complex than Penelope or Ξ Gundam, so you'll really need to follow the manual carefully step by step. That said, it's well reinforced with a number of joint parts, so the fit after transformation is solid. However, since the shape remains so complex even after transforming, the difference between the two modes somehow doesn't feel as dramatic as you'd expect. It's actually a very involved transformation, but I have a feeling someone watching might just say "wait, did you just fold the legs back?" Either way, even for me — someone who's built pretty much every Gunpla out there — this is the first time I've encountered a kit with a shape so complex that my brain genuinely struggles to register the change in form.

And as you can see from the review above, Alyzeus itself isn't a kit you should expect much articulation from. The limbs are basically decorative armor, and it's not really a shape that lends itself to dynamic poses. But honestly, this is a kit that shows off incredible sculptural beauty and presence just standing still, so the focus should be less on articulation and more on solid joints and stability. In particular, placing it on the included stand — which accommodates the rear stabilizer support — allows for a very stable display, and if you lower the stabilizers to use them as ground supports, it can stand upright just fine without the stand too. That said, even with sturdy hip joints, the legs are so heavy that holding a raised-leg pose is pretty difficult to pull off.

All in all, they've done a great job bringing this massive, incredibly complex design to life with excellent three-dimensionality and solid durability. Given the steep ¥12,000 price tag, the so-so color separation and the hand dorsal parts are a bit disappointing, but everything else was satisfying. Personally, I was genuinely in awe building it — it was a different kind of experience from any other Gunpla I've built. I wouldn't go so far as to call it a masterpiece, but I'd definitely call it an epic work. Either way, I honestly don't know if we'll ever see another kit that radiates this much presence and sheer force just by standing there. :-)

PS) It still ticks me off that the palm-sized box of the (flimsy) PGU Nu Gundam LED set cost more than this kit...
