The verdict

I like this kit for exactly the reason some builders will dismiss it: it is not a new mobile suit so much as a smart remix of a suit that already had its engineering sorted out.

This is the Kehaar II escort configuration of the TR-6 line, and Bandai built it on the same core frame as the earlier HGUC TR-6 [Hazel II], adding freshly molded armor and thruster parts for the flight unit. That means the parts of this kit that matter most, the joints and the torso, were already proven before this box existed. What you get is a transforming recon unit with real presence and a gimmick that actually pays off on the shelf.

Best for: AOZ completionists and transformation-gimmick fans who don't mind hunting down a P-Bandai exclusive

The full review

What it is

This is the escort and reconnaissance variant of the RX-124 line from Advance of Zeta: The Flag of Titans, built to fly cover for the Inle mothership. It folds down from a humanoid mobile suit form through an intermediate half-folded stance into a disc-shaped mobile armor mode, and Bandai clearly designed the kit around that switch rather than tacking it on. The included display base is not filler, it is there because the kit wants you to actually pose the thing mid-transformation or airborne holding its composite shield booster. Building on the established TR-6 frame means the core assembly goes together with the confidence of a kit whose bones have already been tested in an earlier release.

The catch

This was a P-Bandai exclusive, first shipped in mid-2020 with a later batch in January 2021, so you are not finding it on a shelf. Expect to pay import or aftermarket prices well above its original yen tag, and expect a wait if you order through Premium Bandai's reissue windows. Because the core frame and much of the tooling comes from the Hazel II release, a chunk of what you are building is a remix rather than something wholly new, which will bother builders who want every kit to feel like a fresh sculpt. The transformation gimmick also means extra small connector and panel parts that need careful nub cleanup so the folded seams close up cleanly.

Who it's for

Grab this one if you are already following the TR-6 lineup or the Advance of Zeta side story and want the recon/escort variant to sit next to Hazel II and the rest of the family. The transformation gimmick and the display base make it a satisfying build for anyone who likes kits with a mechanical trick to show off, not just a static pose. Skip it if you only want mainline Universal Century Gundams, if P-Bandai pricing and availability are a dealbreaker, or if you specifically want a kit that isn't sharing its frame with something else on your shelf. As a value proposition for AOZ fans it earns its place; as a general-audience HG it is a harder sell.

What works

Transformation between mobile suit, intermediate, and mobile armor forms is a genuine build highlight, not a token gimmick
Inherits the sorted-out joint and torso engineering from the earlier HGUC TR-6 [Hazel II] release
Comes with a proper display base built around posing it holding the composite shield booster, so the accessory load actually gets used

Worth knowing

P-Bandai exclusive release means real hunting and import/aftermarket pricing rather than shelf availability
Shares a large part of its tooling with Hazel II, so a chunk of the kit is a remix rather than a fresh sculpt
Transformation-oriented parts add extra small connector pieces that need careful cleanup to keep folded seams tight

The build story

What the build is actually like, and the engineering worth knowing about.

Because this kit shares its core frame with the earlier HGUC TR-6 [Hazel II], the fundamental build experience, joint tolerances and torso assembly, comes from tooling Bandai had already worked out, so the frame goes together with more confidence than a from-scratch kit at this line's price point. The newly molded Kehaar armor and flight unit parts add the bulk of the extra assembly time, and that is where the fiddlier small-part cleanup shows up.

The standout here is the transformation itself: mobile suit to a half-folded intermediate stance to a full disc-shaped mobile armor, all without needing separate part swaps for each mode. The included display base is built specifically to let the kit hold that airborne, in-transition look, and the composite shield booster gives it a weapon loadout that actually matches its escort role in the fiction rather than a generic add-on gun.

Lore & trivia

01The Kehaar II is an escort and reconnaissance configuration built to protect the RX-124 Gundam TR-6 [Inle] mothership, and its EWAC-focused setup is also referred to as the Force Reconnaissance Form.
02It shares its base RX-124 Gundam TR-6 [Woundwort] frame with the earlier Hazel II configuration, both part of Bandai's Model Integration Plan lineage that succeeds atmospheric-use suits like the Asshimar, TR-3 Kehaar, and Byarlant.
03The kit first shipped as a Premium Bandai exclusive in June 2020, with a later production batch shipping in January 2021, and was also offered as a six-unit multi-pack for squadron builds.
04It comes from Advance of Zeta: The Flag of Titans, a Universal Century side story told through photo-novel format rather than an animated series.
