Professor Utonium from The Powerpuff Girls: A Lab Coat, a Heart of Gold, and a Whole Lot of Sugar

Behind every superhero trio is one iconic lab-dad with an earnest voice, excellent posture, and a heart full of love—and that’s Professor Utonium. The ever-doting father of Blossom, Bubbles, and Buttercup, Professor Utonium’s look is clean, classic, and surprisingly easy to pull off with the right styling. Whether you're pairing up with Powerpuff Girl cosplayers or stepping into cosplay solo, this guide will help you become the professor we all secretly wish raised us.

From his trademark lab coat to subtle styling details like contact lenses and nails, here’s how to perfect a look that’s 50% science, 50% sweetness, and 100% cosplay charm.

The Outfit: A Lab-Coated Icon

Professor Utonium’s outfit is minimal, practical, and totally recognizable. His uniform consists of a long white lab coat worn over a crisp white button-down shirt, paired with black slacks and a black tie. It’s the kind of look that says “I accidentally created life while making a science smoothie” and we love that for him.

Make sure your lab coat is well-fitted—not too baggy—so the overall silhouette stays sleek and cartoon-faithful. Press your shirt, polish your shoes, and let the simplicity shine. Add a name tag or a small beaker prop for fun, and you’re ready to educate, protect, and parent your way through any convention.

Hair and Grooming: Smooth, Sharp, and Scholarly

Professor Utonium has that classic 1950s cartoon scientist vibe: jet-black hair, neatly combed, with a slight volume at the front. Use a side part and a matte pomade or gel to style your hair with a slight swoop, keeping everything smooth and structured. If you don’t have dark hair, a short, black cosplay wig works perfectly—just be sure it’s tidy.

A clean shave or neatly groomed facial hair keeps the look polished. You’re a professor, after all.

Eyes with Intellect: Colored Contact Lens Tips

In the show, Professor Utonium’s eyes are just black dots—but we’re elevating the look for real-world cosplay. Using colored contact lenses is a great way to give the professor a bit more personality and dimension while staying true to the aesthetic.

Go for warm brown or charcoal gray lenses to add depth without distracting from the minimal outfit. If you want to lean into his gentle, fatherly charm, a soft hazel or amber lens can warm up your features. Lenses with a subtle enhancement ring will give you a more animated, expressive gaze without going full cartoon.

Think of it as bringing a stylized, live-action version of Professor Utonium to life—clean, polished, and eye contact that radiates “I care about my daughters and also accidentally invented them.”

Nails: Subtle or Super Sweet

Professor Utonium might not rock flashy manicures in the lab, but that doesn’t mean your cosplay can’t have a fun detail that nods to the girls he adores.

For a classic look, keep nails short, filed, and clean. A sheer matte topcoat or buffed natural nail is perfect for a minimalist, clean finish.

Want to add a playful twist? Use EyeCandys Gel Nail Stickers in pastel shades to pay tribute to Blossom (pink), Bubbles (blue), and Buttercup (green). You could even do one nail for each daughter—or go all out with a skittle mani in their signature colors. It’s an easy, removable way to personalize the look and add that sweet sugar-and-spice flavor without clashing with the professor’s formal outfit.

Personality and Posing: Dad Energy, But Make It Heroic

Professor Utonium is calm, curious, nurturing, and just a little bit awkward in the most endearing way. Channel that energy in your poses:

Stand tall, hands confidently behind your back or folded in front. Tilt your head slightly when “lecturing” or looking thoughtful. For group shots with Powerpuff Girl cosplayers, pose protectively or proudly—hands on their shoulders, arms crossed with a smile, or holding a clipboard while keeping an eye on their antics.

Facial expressions should lean thoughtful, kind, or gently concerned—classic cartoon dad who’s just trying his best with three super-powered daughters and a very chaotic city.

Final Touches and Add-Ons

If you’re accessorizing, consider a beaker or test tube prop, a clipboard with “Chemical X” written at the top, or even a plush Mojo Jojo to carry as a subtle nod to your arch-nemesis. Add a flower pin on your coat to match Blossom’s hair bow, or wear socks in the Powerpuff Girls’ colors for a hidden layer of extra love.
