When asked to name iconic blue-haired cartoon characters, most people who aren’t huge cartoon fans will quickly throw out names like Sonic, Stitch, and Cookie Monster — and then draw a blank.
But once going further into the world of anime and cartoon series, you’ll find WAY more fictional characters rocking those blue locks than you’d expect! Keep scrolling to check out the 20 most famous ones on our list.
Top 20 Famous Blue-Haired Characters You Can’t Miss
1. Sonic (from Sonic the Hedgehog)
Sonic the Hedgehog, with his signature blue quills and crazy-fast speed, has become an iconic video game character over the years.
Blue reminds us of the open sky and flowing water – representing freedom and smooth movement, which fits Sonic perfectly. Those blue quills make him instantly recognizable and set him apart as the hero we all know and love.
2. Stitch (from Lilo and Stitch)
One of the two main characters in the titular series Lilo and Stitch, Stitch is part dog, part cat, part kangaroo, and part dragon.
His creator, Jumba, may have chosen blue to reflect Stitch’s mischievous and rebellious spirit. The blue fur could also be a nod to Stitch’s alien origins, suggesting his appearance is worlds apart from that of regular Earth creatures.
3. Joy (from Inside Out)
In Disney-Pixar’s Inside Out, Joy is one of the five core emotions running the show inside Riley Andersen’s mind. She’s meant to keep things upbeat— cheerful, optimistic, and energetic, always working to keep Riley happy.
That’s why the blue hair is a perfect visual for her character: blue often reminds us of happiness and calm, which fits Joy’s positive personality like a glove! Not to mention, blue also pops against the colors of other emotions, making it all the more clear that Joy has a special role in keeping Riley balanced.
4. Marge Simpson (from The Simpson)
Marge Simpson, the heart and soul of the Simpson family, is famous for her endless love and support, even when everything around her is pure chaos.
And, of course, you can’t miss her iconic blue hair! It’s practically a symbol of who she is. That towering blue sets her apart from the rest of the family with their brighter colors, further implying that Marge is the steady, reliable rock that holds them all together.
5. Coraline Jones (from Coraline)
The main star in Neil Gaiman’s novel (and its animated movie), Coraline, is a curious, independent female character who stumbles upon a parallel world eerily similar to her own — but with a creepy twist!
One thing that truly stands out about Coraline is her striking blue hair, which is likely a deliberate choice by the creators to emphasize her unique and adventurous nature.
6. Hades (from Hercules)
Hades, the god of the Underworld in Disney’s Hercules, is a powerful but often misunderstood character.
Given his fiery ambition and constant scheming to take down his brother, Zeus, he’s not your typical villain! His blue, flame-like hair seems to be a nod to his hidden desires for power (though some interpret it as a mere reflection of his unique role as the ruler of the Underworld).
7. Rick Sanchez (from Rick and Morty)
As the wild genius at the heart of Rick and Morty, Rick Sanchez is known for being a brilliant yet seriously flawed scientist. He’s always pulling his grandson, Morty, into crazy, often dangerous interdimensional escapades.
What’s interesting is the contrast between the blue color in Rick’s hair (which usually symbolizes intelligence and calm) and his chaotic, unpredictable nature. It seems the creators were trying to hint at the genius beneath all his madness!
8. Nefertari Vivi (from One Piece)
Nefertari Vivi brings great depth to the story as one of the most popular characters in the world of One Piece. This blue-haired anime girl is not only a princess (of the desert kingdom of Alabasta) but also a warrior with a strong sense of justice.
Her long, bright blue hair, set against the warm, sandy tones of her homeland, makes Vivi even more unforgettable. One can even say Vivi’s hair symbolizes her lifelong dream for a better, war-less, and more harmonious world.
9. Emily (from Corpse Bride)
Emily is a young woman from the afterlife who, thanks to a twist of fate, ends up marrying a living man named Victor.
What truly makes her stand out (besides being dead) is her striking blue hair, which contrasts well with the earthy, muted tones of the living world. It also feels like a reflection of her longing for love and connection – especially since blue often symbolizes loyalty and trust.
10. Cookie Monster (from Sesame Street)
Who doesn’t love this big, blue, cookie-obsessed guy? He’s got a friendly, lovable vibe and – of course – that signature craving for cookies that never seems to end!
His bright blue fur might be a fun metaphor for his limitless appetite (the bigger the fur, the bigger the cookie cravings). Or it could just be a perfect fit for the magical, anything-goes world of Sesame Street, where imagination rules and nothing is too “out there.”
11. Nagisa Shiota (from Assassination Classroom)
Nagisa Shiota might seem like a quiet, gentle student in Assassination Classroom. But don’t let that fool you; he’s a super-skilled assassin who aims to take down his not-so-average teacher, Koro-sensei.
One thing that stands out about Nagisa is his long, blue hair, which is styled more like a girl’s. The reason behind his look is pretty heartbreaking: his mother, who wanted a daughter, forced him to wear dresses and keep his hair long to fit her idea of the perfect child.
12. Sailor Mercury (from Sailor Moon)
One of the iconic Sailor Guardians from Sailor Moon, Ami Mizuno, really stands out with her smarts and analytical skills – not to mention her signature blue hair, which perfectly reflects her connection to the planet Mercury.
Plus, you could say blue is a metaphor for her vast knowledge; just like Mercury is the closest planet to the sun, Sailor Mercury is always the first and quickest to analyze any situation at hand.
13. Joi (from Blade Runner 2049 Animation)
Joi is a hologram and plays the role of K’s closest companion (K is a replicant whose job is to hunt down other replicants).
What makes Joi stand out is not just that she’s an AI with access to endless amounts of information and lightning-fast processing power but also how she looks. Her blue hair pops against the gritty, muted colors of the film’s dystopian world, which makes her feel both futuristic and almost unreal at the same time.
14. Rei Ayanami (from Neon Genesis Evangelion)
Another name on our list is Rei Ayanami, a mysterious, quiet girl who pilots the impressive Evangelion Unit 01.
The color blue often ties into nature (sky and water) and spiritual elements, all of which symbolize Rei’s aura quite well. Being a clone and a vessel for the Third Angel, she’s connected to the spiritual realm in a way that goes far beyond what’s human, another reason why so many audiences find her intriguing.
15. Princess Luna (from My Little Pony: Friendship Is Magic)
Princess Luna has a pretty huge job: she rules over the night and watches over everyone’s dreams, ensuring everything stays peaceful when the world goes to sleep.
Being the ruler of the night, Luna has a deep, almost mystical connection with nature and all the hidden forces that keep things in balance. Hence, her night-like, gorgeous blue hair is a cosmic reminder that she’s in tune with the universe, seeing far beyond what meets the eye.
16. Furrball (from Tiny Toon Adventure)
In Tiny Toon Adventures, Furrball always gets into some kind of mischief, but that’s part of what makes him so lovable. And let’s not forget his tight bond with the rest of the Tiny Toons crew, his second family.
The blue fur is a clever indicator of his feline heritage. Since cats see blue better than any other color, it seems the creators want to tell us that no matter how funny or goofy Furrball looks, he’s still a true cat at heart.
17. Juvia Lockser (from Fairy Tail)
This blue-haired anime girl has been widely recognized as a powerful water mage with the ability to manipulate water. Her blue hair, therefore, obviously represents her deep connection to water.
As a water mage, Juvia can also cleanse and bring new life wherever she goes. Hence, the color blue indicates she has the strength to give fresh starts and hope to friends and comrades around her – like a calming rain after a storm.
18. Ember McLain (from Danny Phantom)
There’s no denying Ember McLain is one of the most unforgettable characters from Danny Phantom. She’s a ghost with a serious attitude, fire-controlling ability, and a rebellious streak that just makes her twice as intense.
Ghosts are usually portrayed as mysterious beings out of this world, so her blue hair adds to this ethereal look. Plus, blue is often tied to the sky and water (fluid, untouchable elements), which, in a way, symbolizes her ability to phase through solid objects.
19. Bulma (from Dragon Ball)
We are talking about a genius female inventor with a knack for tech and a bold, adventurous streak that keeps things exciting! Bulma’s fiery personality makes her one of the most memorable characters around.
As briefly mentioned above, blue is linked to intelligence and loyalty — key traits that Bulma often shows through her strong relationships with friends and family. But what’s really interesting is how that cool, calm color contrasts significantly with her spontaneous and thrill-seeking nature, which makes her even more dynamic and unpredictable.
20. Milhouse Van Houten (from The Simpsons)
Milhouse Van Houten is the lovable, geeky kid from The Simpsons who always manages to stand out—mostly because he’s Bart Simpson’s best friend, but also because he’s just so… Milhouse. He’s the classic “nerdy” character, often clueless and socially awkward, finding himself in situations that seem way over his head.
As a result, his blue hair is not your usual Springfield hairstyle; while most characters rock more typical hair colors, Milhouse’s bright blue locks are visual cues that tell the audience, “Yeah, this guy’s different!”
