HGAC 1/144 OZ-19MASX Gundam Griepe – Gunpla Model

HGAC OZ-19MASX Gundam Griepe is a Premium Bandai-exclusive High Grade After Colony kit slated for February 2026, reviving G-Unit’s transformable OZ-19MASX platform with modular frames and Assault Mode conversion parts for the first time in the HGAC line.¹

Overview

Bandai Spirits is positioning the Gundam Griepe as the capstone to its modern G-Unit push: the kit introduces entirely new tooling to depict the AEUG-engineered assault machine and to future-proof the “G-Unit composite” gimmick across the Geminass, L.O. Booster, and Aesculapius kits.¹ Premium Bandai’s launch has been timed to follow the early-2020s reprints of the Geminass siblings, ensuring collectors have a clear upgrade path when building the combined G-Unit loadout. Pricing is set at ¥4,510 before tax, reflecting both the sizeable weapons runner and the multiple frame assemblies bundled into the box.¹

Features

Triple-frame modularity: The package includes MA and dual G-Unit frame sets so builders can configure the Griepe in Mobile Armour, Assault, or standard mobile suit silhouettes without third-party parts.¹
Cross-kit compatibility: Select armour and weapon segments can be shared with the HGAC Geminass platform and the Assault Booster/High Mobility add-ons, enabling accurate recreations of key manga loadouts.¹
Heavy beam arsenal: The Hyper Mega Particle Launcher, Beam Lancer, and Buster Mega Particle Cannon nosecone are all supplied, with swappable manipulators to support each pose.¹
Display-ready promo styling: Bandai’s official sample photography emphasises the kit’s matte finish and sharply printed caution markings, giving repainters a clear surface roadmap.¹

Build experience

The layout follows recent HGAC engineering principles: colour separation is handled with layered armour shells rather than foil stickers, while the inner frame relies on a mix of PS and PE for flexibility in transformation joints. Expect partsforming across the MA and Assault Mode conversions—the kit spreads the load across separate frame assemblies to avoid over-stressing swing joints. While Premium Bandai tooling typically arrives with precise gate placement, dry-fitting is advisable around the shoulder pylons and the massive launcher barrel to keep seams aligned prior to topcoating.¹

Comparisons & reissues

This Premium Bandai edition is a brand-new mold rather than a recolour, standing apart from the 2000-era non-grade release that most collectors previously relied on. The engineering philosophy mirrors the HGAC Gundam Aesculapius and L.O. Booster projects, meaning the Griepe should share tolerances—and colour plastic—across the combined G-Unit ensemble. Expect further kit-bash potential once Bandai completes the assault team reissues.¹
