For mecha enthusiasts and Gunpla builders, the term “Perfect Grade” (PG) has always represented the gold standard of detail and engineering. However, the PG Unleashed (PGU) RX-78-2 Gundam doesn’t just meet that standard—it completely redefines it. Released to commemorate the 40th anniversary of Gunpla, this kit is often described as the “ultimate building experience.”

🛠️ The “Unleashed” Evolution: 5 Phases of Construction
The genius of the PGU lies in its Phase-led assembly system, which mimics the actual construction of a mobile suit:
- Phase 1: The Core Frame. Utilizing the largest “Insert Frame” in Gunpla history, you can snap together the entire inner skeleton in record time.
- Phase 2: Mechanical Detail. Layering intricate, multi-layered internal frames that add weight and mechanical realism.
- Phase 3: The Truss Frame. Adding “Truss” structures that create a sense of depth and complexity rarely seen in 1/60 scale models.
- Phase 4: Multi-Material Armor. This is where the kit shines. It uses a mix of matte, chrome, and silver plating, along with metal parts and etching stickers for a high-end look.
- Phase 5: The Final Form. Attaching the exterior armor with a focus on the “Open Hatch” gimmick, allowing you to reveal the mechanical marvel underneath.

✨ Why It Stands Out
- Extreme Articulation: With over 90 points of articulation, including sliding armor panels that move when you flex the joints, the PGU is the most posable Gundam ever made at this scale.
- No Paint Required: Thanks to the “Multi-Material” approach, the kit looks like a professional custom build right out of the box. The contrast between the metallic parts and the classic tricolor scheme is stunning.
- The Open Hatch Gimmick: Over 53 hatch-opening points allow you to display the Gundam in “maintenance mode,” showing off the three-layered internal frame.
📝 Final Verdict
The PG Unleashed RX-78-2 is more than just a model kit; it’s a celebration of Bandai’s 40 years of engineering prowess. Whether you are a veteran builder or someone looking for a definitive centerpiece for your collection, this kit offers an unmatched sense of satisfaction.
Builder’s Tip: Make sure to have a high-quality pair of nippers and a steady hand for the etching stickers. The LED unit requires LR41 batteries (usually sold separately), so grab a pack before you start!
