A complete step-by-step guide to assembling the HGUC MS-06S Zaku II Char's Custom (Ver.A), including tools, nub removal, panel lining, and decaling tips.

The HGUC MS-06S Zaku II Char's Custom (Ver.A) is a timeless kit that every Gunpla builder should experience. Despite its age, this kit offers a faithful recreation of Char Aznable's iconic red mobile suit, with excellent articulation and detail for its scale. Whether you're a beginner looking for your first build or a veteran wanting to revisit a classic, this step-by-step guide will help you assemble your Zaku II with confidence.

In this guide, we'll cover everything from the tools you'll need to the final decal application. We'll also share tips on how to achieve a clean build, avoid common mistakes, and add extra detail to make your Zaku stand out. By the end, you'll have a display-ready Char's Zaku II that looks like it just stepped out of the One Year War.

Tools and Preparation

Before you start cutting runners, it's essential to gather the right tools. At minimum, you'll need a pair of nippers, a hobby knife, and some sandpaper or a glass file. For a cleaner finish, consider using a cutting mat and a parts separator. If you plan to panel line, have a fine-tip Gundam marker or panel line accent color on hand.

Additionally, having a good set of decals can elevate your build. The Delpi Decal RG Shining Gundam is a popular choice for adding sharp, detailed markings, but for your Zaku II, you might want to explore waterslides that match the Zeon aesthetic. Remember to prepare a small container of water for waterslide decals if you choose to use them.

  • Use single-bladed nippers to cut parts from the runner, leaving a small nub.
  • Sand nubs with 400 to 800 grit sandpaper for a smooth finish.
  • Always cut away from yourself and use a hobby knife for precision.

Step 1: Assembling the Torso and Core Block

Start with the torso, as it forms the central hub for the rest of the kit. The HGUC Zaku II (Ver.A) has a simple yet sturdy core block that connects the chest, waist, and backpack. Assemble the chest piece, ensuring the vents are cleanly cut and the monoeye camera is in place. If you want to add extra detail, you can paint the inner frame with a metallic color before closing it up.

For Char's custom, the red torso is iconic. To achieve a deeper, more vibrant red, consider using a candy coat technique. The Kustom Service Candy Orange 30ml is an excellent choice for a clear orange overlay that adds depth to the red plastic. Apply a gloss black base, then a metallic silver, and finish with the candy orange for a striking effect.

  • Test fit parts before applying glue or paint to ensure a proper fit.
  • Use a toothpick to apply small amounts of cement for a secure bond.

Step 2: Building the Arms and Weapons

The arms of the Zaku II are straightforward, but they include the iconic shield and the 120mm machine gun. Assemble the shoulder armor, upper arm, forearm, and hands. The hands are articulated, allowing you to hold the machine gun or the heat hawk. For a more dynamic pose, you can swap hands easily.

When building the machine gun, pay attention to the barrel and magazine. You can add a photo-etched detail to the thruster nozzles on the backpack or the shield for a more realistic look. The AW-009A Photo Etch Thruster Nozzles are perfect for this, providing a metal finish that contrasts nicely with the plastic.

  • Apply a small amount of matte topcoat to the hands to improve grip.
  • For the shield, consider adding a subtle weathering effect using dry brushing.

Step 3: Legs and Skirt Armor

The legs are the most complex part of the Zaku II, with multiple segments that allow for a wide range of motion. Assemble the upper thigh, knee, lower leg, and feet. The knee joint is particularly important for dynamic poses, so make sure it's tight but not too stiff. The skirt armor attaches to the waist and can be moved out of the way for better leg articulation.

For a more realistic look, you can add panel lines to the legs using a fine-tip marker. The Gundam Color UG12 MS Sazabi Red 10ml is a great paint for touch-ups or for painting the small details on the legs, such as the pipes on the ankles. If you're using the 30MS SIS-A00 Tiasha (Color B) as a base for customizing, you can mix and match parts for a unique Zaku variant.

  • Use a parts separator to avoid stress marks when disassembling.
  • Apply panel line accent to the grooves and wipe off the excess with a cotton swab.

Step 4: Panel Lining and Detailing

Panel lining is what brings out the details of the kit. Use a black or gray panel line marker to trace the lines on the armor. For Char's Zaku, a black panel line on the red parts creates a strong contrast. You can also use a fine-tip pen for tighter lines. If you make a mistake, use a rubber eraser or a cotton swab dipped in alcohol to clean up.

For an extra level of detail, consider adding waterslide decals. The Delpi Decal HG Penelope (GRAY + RED) includes a variety of markings that can be adapted for the Zaku, but you might also want to look for Zeon-specific decals. Apply them with a soft brush and a decal setter for a smooth finish. Remember to topcoat after decaling to protect them.

  • Use a gloss topcoat before panel lining to make the ink flow easier.
  • For a more realistic look, apply a dark gray wash to the panel lines instead of black.

Step 5: Final Assembly and Display

Once all parts are assembled and detailed, it's time to put everything together. Attach the arms, legs, and backpack to the torso. The monoeye camera can be rotated for a menacing look. If you have the Gundam Wing Logo Display, you can use it as a backdrop for a dramatic display. Alternatively, you can create a simple action base using a clear stand.

For the final touch, apply a matte topcoat to seal everything and reduce shine. This gives the kit a more realistic, military appearance. If you prefer a glossy look, use a gloss topcoat instead. Once dry, your HGUC Zaku II Char's Custom (Ver.A) is ready for action!

  • Pose the Zaku in a dynamic stance, such as holding the machine gun with one hand and the heat hawk in the other.
  • Use a photo booth or a simple white background for a professional-looking photo.

Building the HGUC MS-06S Zaku II Char's Custom (Ver.A) is a rewarding experience that any Gunpla enthusiast will enjoy. With the right tools and a bit of patience, you can create a stunning display piece that pays homage to the Red Comet. If you're looking to add extra detail, consider picking up the AW-009A Photo Etch Thruster Nozzles to enhance the backpack, or the Delpi Decal RG Shining Gundam for a unique decal set. Happy building!
