A step-by-step guide to assembling the GATTAI Da-Garn X rerelease from Good Smile Company. Learn key transformation steps and common pitfalls.

Quick Answer

To build the GATTAI Da-Garn X rerelease, start by carefully removing parts from the runners, then follow the manual's order for each of the five component vehicles before combining them into the robot mode. Pay close attention to joint alignment during transformation to avoid stress marks.

Why This Rerelease Needs Careful Assembly

The GATTAI Da-Garn X is a detailed collectible from Good Smile Company, not a snap-fit model kit. Parts are pre-painted and some joints are tight out of the box. Rushing the assembly or forcing connections can damage the finish or break pegs. Taking your time with each step ensures a solid combined mode and preserves the figure's value.

Tools You May Need (Not Included)

You do not need glue or paint for this rerelease. A pair of side cutters (nippers) helps clean nubs from the runners, and a small flathead screwdriver can gently pry apart tight joints if you need to separate parts later. Have a soft cloth or mat to protect painted surfaces during assembly.

Step-by-Step Assembly Guide

  1. Step 1: Organize and Inspect Parts: Lay out all runners and the instruction sheet. Check that every part matches the manual. Identify the five vehicle components: the main body, arms, legs, and accessories. Common mistake: skipping the inventory and later realizing a small piece is missing or broken. If a part is missing or damaged, contact the retailer before cutting anything from the runners.
  2. Step 2: Cut Parts Cleanly from Runners: Use side cutters to snip each part away from the runner, leaving a small nub. Then trim the nub flush with a second cut or a hobby knife. Do not twist parts off the runner — this can stress the plastic and leave white marks. Common mistake: cutting too close to the part on the first snip, which can gouge the surface. Sand or file any remaining nub gently with fine-grit sandpaper (1000+) to keep the finish smooth.
  3. Step 3: Assemble Each Vehicle Separately: Follow the manual to build the five individual vehicles: the main jet, the two arm units, and the two leg units. Each vehicle has its own transformation sequence. Do not force pegs — if a joint feels too tight, check for mold flash or misalignment. Common mistake: assembling vehicles in the wrong order, which can make later combination impossible without disassembly. Test each vehicle's transformation into its combined-mode position before moving on. If a joint binds, apply a tiny amount of silicone lubricant (not oil-based).
  4. Step 4: Combine into Robot Mode: Start with the main body, then attach the leg units, then the arm units. Follow the manual's combination sequence exactly. Lock each connection fully before moving to the next. Common mistake: partially inserting a peg and then trying to force the next connection, which can stress the entire structure. If a peg does not click into place, separate and realign — never hammer or push with excessive force.
  5. Step 5: Pose and Display: Once combined, gently move the joints to your desired pose. The figure is heavy in combined mode, so spread the legs for stability. Common mistake: overextending a joint beyond its designed range, which can pop the part loose or crack the plastic. For long-term display, use a clear acrylic stand to support the figure's weight and reduce stress on the hip joints.
