Customizing action figures—specifically focusing on the vibrant, high-stakes aesthetic of the Invincible universe—is a rewarding journey that transforms mass-produced toys into one-of-a-kind art pieces. Whether you want to recreate Mark Grayson’s iconic blue-and-yellow suit, the brutal battle damage from a Viltrumite encounter, or a custom Omni-Man variant, this guide will walk you through the process.
This project is rated at an Intermediate Skill Level. While a beginner can certainly achieve great results, the process requires patience, steady hands, and a basic understanding of color theory and paint adhesion. You don’t need to be a professional sculptor, but you do need to be comfortable working with small, delicate components.
Tools List:
* Hobby knife (X-Acto) with #11 blades
* Needle-nose pliers and tweezers
* Fine-point paintbrushes (000, 0, and 2 sizes)
* Micro-spatulas for sculpting
* Dremel rotary tool (optional but recommended)
* Painter’s tape (fine-line tape)
Materials Needed:
* Base action figure (6-inch or 7-inch scale)
* Acrylic model paints (high-pigment brands like Vallejo or Citadel)
* Epoxy putty (Aves Apoxie Sculpt is the industry standard)
* Plastic primer (spray or brush-on)
* Matte and gloss clear coat sealers
* Rubbing alcohol (for surface prep)
Estimated Time and Cost:
For a standard custom repaint and minor sculpting, expect to spend between 12 to 20 hours spread over a week to allow for proper drying times. The cost is relatively low, typically ranging from $40 to $80 if you are buying supplies for the first time, though the cost per figure drops significantly as you build your collection of paints and tools.
Preparation and Planning
Before you touch a single brush to plastic, you must prepare. Customizing is 80% preparation and 20% execution. Start by selecting your base figure. For Invincible customs, look for figures with articulation points that match the character’s build—a muscular, heroic frame is essential for Viltrumites.
Safety Precautions:
Safety is non-negotiable. Always work in a well-ventilated area, especially when using spray primers or clear coats, as these contain VOCs. Wear a dust mask when sanding plastic or epoxy putty to prevent inhaling micro-particles. Keep your hobby knife sharp; a dull blade is more dangerous because it requires more force and is prone to slipping.
Workspace Setup:
Set up a dedicated station with excellent overhead lighting. A magnifying lamp is a game-changer for detail work on faces or emblems. Cover your workspace with a self-healing cutting mat or a sheet of glass to keep your surface clean. Organize your paints in a rack or tray so you aren’t fumbling for colors while paint is wet on your brush.
Planning Tips:
Don’t dive in blindly. Sketch your design on a printed photo of the base figure. This helps you map out where the paint transitions should occur. If you are aiming for a show-accurate look, have high-resolution reference images open on a screen nearby. Consider the “joint rub” factor: identify where the limbs move and plan to sand down those areas slightly. If you don’t remove plastic from the joints, the paint will scrape off the moment you pose the figure. This foresight is what separates a amateur toy modification from a professional-grade display piece. Finally, ensure your figure is clean; use a toothbrush and dish soap to remove factory oils, then wipe down with rubbing alcohol. A clean surface is the foundation of a paint job that won’t chip or peel.
Step 1: Disassembly and Surface Preparation
The first major step is preparing the canvas. You cannot paint directly onto a factory-finished figure; the paint will bead up or peel.
Step-by-Step Instructions:
1. Boil and Pop: To prevent breakage, submerge the figure in near-boiling water for 60 seconds. This softens the plastic, allowing you to “pop” the limbs and head off the joints without snapping the pegs.
2. Sanding: Use fine-grit sandpaper (400-600 grit) to scuff the entire surface of the figure. This creates “tooth” for the primer to grip. Pay special attention to the joints. Use your Dremel or sandpaper to shave off a thin layer of plastic from the inner ball-joints and hinges to create clearance for your future paint layers.
3. Priming: Apply a thin, even coat of plastic-compatible primer. I recommend a grey primer, as it allows you to see surface imperfections easily. If you are using a spray can, hold it 8-10 inches away and use quick, sweeping motions. Do not over-spray, or you will lose the sculpted detail.
Tips and Tricks:
Keep your primer coat thin. If you lose detail, you’ve applied too much. If you see bubbles, stop immediately and let it dry before sanding them down.
Common Mistakes:
A common error is skipping the boil-and-pop method. Forcing a joint to move while it’s cold is the fastest way to break a peg. Another mistake is failing to sand the joints; if you don’t create clearance, the figure will look great on the shelf but will chip the moment you try to put it in a “flying” pose.
Visual Description:
Your figure should look uniform and dull after priming. There should be no shiny factory paint visible. If the surface looks “fuzzy,” you are sanding too aggressively; if it looks splotchy, your primer coat is uneven.
Checkpoint:
Ensure all limbs move freely without grinding against the torso. If you feel resistance, sand more. Your surface should be matte, clean, and ready for color.
Step 2: Sculpting and Customizing Details
Now that the base is ready, it’s time to add the specific features that make it an Invincible character. This might include adding the iconic chest emblem or sculpting battle damage.
Step-by-Step Instructions:
1. Mix the Putty: Take equal parts of your Aves Apoxie Sculpt (Part A and Part B) and knead them together until the color is uniform. You have about 1-2 hours of working time.
2. Application: Use your micro-spatula to apply the putty to the figure. To create the chest emblem, apply a thin pancake of putty and use the tip of your hobby knife to cut the shape into it while it’s soft.
3. Smoothing: Dip your finger or a clay shaper tool in a tiny bit of water to smooth the surface of the putty. This eliminates fingerprints and ensures a professional finish.
4. Curing: Let the putty cure for at least 24 hours. It will become hard as rock. Once cured, you can sand it further to get perfectly crisp edges on your sculpted details.
Tips and Tricks:
If you are sculpting battle damage, use a dremel with a small burr bit to carve “gashes” into the plastic before applying a tiny bit of putty to create the torn edges of the skin or suit. This adds depth and realism.
Common Mistakes:
Using too much putty is a frequent pitfall. It’s better to apply two thin layers than one thick, heavy glob that ruins the figure’s proportions. Also, avoid working in a humid environment, as this can affect how the epoxy cures.
Visual Description:
The figure should now have the desired structural changes. The sculpted details should look integrated, not like they are “sitting on top” of the plastic.
Checkpoint:
Check that the putty is fully cured by pressing a fingernail into an inconspicuous area. If it leaves a mark, wait longer. Once hardened, sand the edges so the transition between the plastic and the putty is seamless.
Step 3: Painting and Detailing
This is where the character comes to life. Painting requires steady hands and patience with layering.
Step-by-Step Instructions:
1. Base Coating: Start with your darkest colors first. Apply two thin coats of acrylic paint rather than one thick one. This prevents brush strokes and ensures the paint stays smooth.
2. Layering: Move to your lighter colors. For Invincible’s blue-and-yellow suit, apply the blue base, then carefully paint the yellow sections. If you make a mistake, let it dry and touch it up with a small brush.
3. Washing: To add depth, use a “wash” (a heavily thinned down dark brown or black paint). Apply it to the crevices and muscle definition, then quickly wipe the excess off the raised areas with a paper towel. This creates instant shadows.
4. Highlighting: Use a lighter shade of your base color to dry-brush the raised areas, making the muscle definition pop.
Tips and Tricks:
Use a “wet palette” to keep your acrylics from drying out while you work. A simple DIY wet palette is just a damp paper towel inside a plastic container with parchment paper on top.
Common Mistakes:
Painting directly from the bottle is a major mistake; always thin your paints with a drop of water so they have the consistency of skim milk. Thick paint obscures detail and looks messy.
Visual Description:
The figure should have distinct, clean color blocks. The wash should have settled into the cracks, giving the muscles a three-dimensional, “comic-book” look.
Checkpoint:
Hold the figure at arm’s length. Do the colors look vibrant? Are the lines between the blue and yellow clean? If you see any “bleeding” of colors, use a fine-point brush to clean up the edges.
Troubleshooting Common Issues
Even the best customizers run into problems. Here is how to navigate the most frequent hurdles.
Problem 1: Paint Cracking or Peeling.
This usually happens because the surface wasn’t cleaned properly or the primer didn’t cure. If it’s a small spot, carefully sand it down, re-prime that tiny area, and repaint. If it’s widespread, you may need to strip the paint with a gentle solvent (test on a hidden area first) and start the base coating over.
Problem 2: The “Sticky” Figure.
If your figure remains tacky even after hours of drying, it’s likely because the paint was applied too thick or the humidity in your room is too high. Place the figure in a dry area with a fan blowing on it. Do not apply a clear coat over tacky paint, or it will never dry.
Problem 3: Paint Rub on Joints.
Despite your best efforts, joints are high-friction areas. If you notice paint rubbing off after posing, you have two choices: leave the joint unpainted (a common practice among professionals) or apply a layer of clear matte varnish to the joint area to act as a protective “shield” for the pigment.
When to Seek Help:
If you have accidentally glued a joint shut or snapped a peg, don’t panic. Search for “action figure repair” forums or YouTube channels. There are specialized techniques for drilling out broken pegs and replacing them with metal pins that are very effective. If the damage is purely aesthetic, don’t be afraid to embrace the “battle damage” look—sometimes a mistake is just an opportunity for a new creative direction.
Final Touches and Maintenance
You are in the home stretch. The final steps are what protect your hard work and make it look like a retail-quality product.
Finishing Steps:
Once the paint is completely dry (wait at least 24 hours), apply a clear coat. Use a matte finish for the suit fabric and a gloss finish for the eyes or any “energy” effects. This protects the paint from dust, UV light, and handling. Spray in short, light bursts. Too much spray will create a cloudy, white residue that ruins your paint job.
Quality Check:
Inspect the figure under bright light. Look for stray brush hairs, dust particles trapped in the paint, or uneven edges. Use a sharp toothpick to gently scrape away any paint that has bled onto the joints. Test the articulation one last time to ensure everything moves smoothly.
Maintenance Tips:
Action figures are meant to be displayed, but they are susceptible to dust and heat. Keep your figure away from direct sunlight, which can fade the colors over time, and avoid high-heat areas like windowsills. To clean your figure, use a soft, dry makeup brush to gently dust the crevices.
Care Instructions:
If you need to move the figure, do so by holding it by the torso or the center of the limbs, not by the small accessories or heads. If you find that the joints are getting loose over time, a tiny drop of “Kiki Fix Loose Joints” (a popular hobby product) inside the joint will restore the tension.
Enhancement Suggestions:
Want to take your Invincible display to the next level? Consider creating a custom base. Use a piece of foam board to create a “rubble” effect, or paint a display stand to look like the cratered surface of a planet. You can even add custom accessories, like a miniature “Viltrumite cape” made from thin fabric rather than plastic, which will allow for more natural posing.
Customizing is a lifelong hobby. Every figure you finish teaches you something new about technique, patience, and the joy of creation. Your Invincible figure is now a unique piece of art that reflects your passion for the character and your dedication to the craft. Enjoy displaying your creation!
