What makes brand characters stick?
How to test your distinctive brand assets when they are not yet famous + a free test to see how well your mascot performs.
You already won (kind of)
If you have a mascot, you’re already 6-15x more memorable than brands relying on logos alone. Research from Ipsos backs this up - characters trigger memory structures that abstract symbols or typography simply can’t match.
So congratulations, you’re ahead if you’re even considering a mascot.
But here’s the question: how memorable is your mascot actually? And what if you’re considering designing one? How can you test before you invest?
We’re bombarded daily with amazing examples from characters like Duo and Ronald McDonald but how do we build these characters?
There’s a massive difference between “we have a character” and “we have a character that people can’t forget.” The gap between a generic dog render and the Geico gecko isn’t just creative execution - it’s memorability mechanics.
I was already using a bunch of ‘stress-tests’ in my mascot studio, but I decided to build (read: vibecode) a custom tool so you can test yours, for free. It’s based on 3 simple but crucial tests:
Blur: When you’re scrolling, or driving, brands are often out of focus, this test looks at the overal color layout and clarity of your character
Silhouette: Truly iconic characters have a strong shape, even when it’s dark.
Fragment: You don’t always see the full character, sometimes it’s just walking away, sometimes you’re driving by. Fragment looks at small parts of your mascot in isolation to see if it still holds up.
Most brands never find out until they’ve spent six figures on activation. I built a free testing app so you can know before you invest. It takes a few minutes. You’ll get a score 0-10 and know where you stand.
The honest truth: Marcel failed the test.
I ran Marcel through the BSF test myself. He got a 5.8 out of 10 😅.
Why? He’s a blue dog with accessories (hat, skull collar), but the proportions and shape still fit the “dog realm.” When blurred or in silhouette, he doesn’t scream “THAT’S MARCEL” - he screams “that’s... a blue dog?”
The 0-10 spectrum:
0 points: A generic render of a dog character. It could be anyone’s dog. Stock footage vibes. Zero distinctiveness.
5 points: Marcel (currently). Blue dog with accessories. Distinctive color, some personality, but hard to spot from afar. No strong color blocks or iconic shapes.
10 points: Totally unique character with impossible-to-confuse proportions, distinctive shape, and clear color blocking. Think early Mickey Mouse silhouette or the Michelin Man’s tire segments. Instantly recognizable even as a shadow.
Let’s fix Marcel
The test revealed the gaps. So I’m iterating based on data:
Adding stronger color blocks: black collar (added contrast) and beige mouth area to improve blur test, so it’s not just a blue furry beast.
Adding more distinct features (white gloves as a nod to the OG character Mickey mouse) and a more unique shape to improve silhouette and fragment score
Custom typeface on the hat that becomes part of his identity and improve fragment score
The result? 7.5! He’s now ranking among the greats.

Here’s the thing: 6+ is good enough
You don’t need a perfect 10 to build a great mascot. The Aflac duck, Geico gecko, and Aleksandr the meerkat aren’t silhouette superstars. They’re recognizable animals (okay, maybe not the Aflac duck) that look... like animals.
But they became iconic through:
Unique voice (Aflac’s quack, the gecko’s Cockney accent, Aleksandr’s Russian accent)
Quality creative (actually entertaining ads, not just brand messages with a character slapped on)
Consistent above-the-line spend (TV, billboards, sustained visibility over years)
Years of commitment (not launching and abandoning after 6 months when the CMO changes)
The BSF test tells you if you’re starting from 0 or 5 or 8. But it doesn’t tell you if you’ll win. The memorability mechanics get you in the game. The voice, creative execution, and media strategy determine if you dominate it.
A 6+ score means you have a solid foundation. Below 6? You should probably redesign before you pour media budget into activation. Between 6-10? Optimize the other layers.
Layer 2: Sonic distinctiveness
Visual shape gets you noticed. Voice & sound get you remembered.
Ask yourself:
Does your character have a unique voice (not “friendly corporate narrator #47”)?
Can people identify your brand from 3 seconds of that voice alone?
Is the voice consistent across every touchpoint (not different voice actors in different markets)?
Voice is a memory structure as powerful as visual shape. Maybe more powerful as the Aflac duck and Meerkats seem to prove.
The fame/uniqueness paradox
Jenni Romaniuk’s fame/uniqueness framework is gold for measuring existing distinctive assets. You survey your market: “How many people know this asset?” (fame) and “How many brands does it make you think of?” (uniqueness).
High fame + high uniqueness = powerful, distinctive asset. Low fame + high uniqueness = weird but unknown. High fame + low uniqueness = generic.
But this framework is terrible for developing new mascots. Why? Because you have no fame yet. People won’t recognize the asset so you’ll score low on all of these attributes.
The better approach when developing a brand asset over time
Test basic visual mechanics (BSF) - aim for 6+ before you activate
Test sonic distinctiveness - can the voice carry recognition alone?
Launch and iterate - does it make people feel something? (funny, cute, weird, annoying in a good way?) Are we getting traction with launch posts? Follow the comments to build a strong asset.
THEN build fame through consistent activation, high-quality creative, and media spend
THEN measure with fame/uniqueness framework 1-2 years after launch
That’s it. A small glimpse into what it takes to build a distinctive character. What do you think of Marcel 2.0? And of course, feel free to share the results of your test in the comments. I’m curious to see how your mascot ranked and if you have any questions.
