The verdict

This is a P-Bandai exclusive that earns its exclusivity tax through real engineering, not just a new color scheme.

Bandai took the Advanced Hazel frame, swapped in TR-6 Haze'n-thley II hardware, and gave the legs revised joints that finally let this lineage stand in a proper wide stance. The new Psycho Blade head unit is a genuinely new mold, not a reused part with a sticker. I like this kit more than I expected to going in.

Best for: AOZ completionists and Titans-era fans who already own the earlier Hazel kits and want the frame problems fixed

The full review

What it is

The Haze'n-thley is the final development stage of the Hazel test-type line from Advance of Zeta, and the kit reads like Bandai's own patch notes for that lineage. It reuses a lot of the Advanced Hazel mold but the leg parts are revised specifically for articulation, and the D-runner is molded in KPS plastic instead of ABS for extra joint flex. The shoulder-mounted beam cannons and the deployable chest High Mega Particle Cannon are both present and they look mean in person. The Psycho Blade antenna unit on the head is a new mold built just for this release, and it changes the silhouette enough that this doesn't feel like a repaint of a kit you already built.

The catch

This was Premium Bandai only, so you're paying import/reseller markup on top of an already HG-scaled part count, and that math will bother value-focused builders. It's still an HG, so panel lines are shallow and some color separation on the torso and backpack leans on stickers rather than molded plastic. A few reviewers flagged fiddly small joint parts around the drum frame and boost pod assembly on the back, the kind of pieces that are easy to lose or misalign if you rush. This is also a niche-within-a-niche suit, so resale and aftermarket decal support are thin if you want to customize further.

Who it's for

Buy this if you've built the earlier Hazel or TR-6 kits and want the version where the legs actually pose wide without looking like they're about to tip over, or if the AOZ manga aesthetic just does it for you. Skip it if you're new to Gunpla and want maximum value per dollar, an HGUC RX-78-2 or a current-mold HG will get you further for less money and less hunting through secondary markets. This is a kit for people who already know they like this specific corner of Titans test-type lore.

The build story

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

The build itself is a familiar HG snap-fit experience with the usual nub cleanup, but the back assembly around the drum frame and boost pod unit is where you slow down. Parts here are small and the fit is tight enough that test-fitting before final snap saves you from stress marks. The KPS D-runner plastic on the legs is noticeably more flexible than the ABS elsewhere, which is the whole point since that's where the articulation fix lives.

Where this kit earns its keep is the frame. The wide-stance leg revision actually works, the suit holds a battle pose without the ankles rolling out, and the PC-123 Plus polycaps mean joints stay tight after repeated posing rather than loosening after a few sessions. The chest High Mega Particle Cannon deploys cleanly and the shoulder beam cannons rotate enough to actually aim, so the gimmicks aren't just static show pieces. For an HG the accessory loadout (twin beam cannons, deployable chest cannon, new head unit) is generous, it just comes at Premium Bandai prices.
