Take a look at 8 of the most iconic blue-haired anime characters, ranging from unforgettable side characters to diabolical villains.
Over the past few decades, anime has given us quite a literal rainbow of hair colors—with black surprisingly being the most uncommon. In fact, the hair color of most anime characters can be represented on a spectrum. Among them, blue-haired anime characters almost always stand out.
These characters may either be completely delusional air-heads or cold-hearted murderous villains. Some of them may have a major impact on the narrative, whereas some may be someone who simply looks good with blue hair. That being said, let us look at the 8 most iconic blue-haired anime characters, ranked in order of their popularity and overall impact on the anime community.
8 Most Iconic Blue-Haired Anime Characters
8) Shun Kaidou (The Disastrous Life of Saiki K.)
Shun Kaidou from The Disastrous Life of Saiki K. might not be the strongest or most popular anime character on this list. That said, he’s hands down the most delusional. He’s perhaps the best representation of characters who suffer from the Chuunibyou Syndrome. In simpler words, he’s a kid who takes his fantasy world way too seriously.
Kaidou is always rambling about his fake alter-ego – the “Jet-Black Wings”, and his inevitable fight against the “Evil Dark Reunion”—which is obviously a made-up legion of supervillains. Despite all this, Kaidou is weirdly lovable. The sheer confidence with which he rambles about his supernatural fantasies is always hilarious to watch. He certainly has heart – despite being weak, he refuses to give up. Moreover, he’s fiercely loyal to his friends and he could probably follow them to the ends of the Earth.
7) Nagisa Shiota (Assassination Classroom)
Nagisa Shiota from Assassination Classroom might look like a cinnamon roll – but don’t let his looks fool you. He’s a trained assassin who’s downright terrifying when he becomes serious and goes for the kill. He started the series as a quiet and gentle boy. By the end, he became one of the most dangerous students of Class 3-E, whose capabilities in combat rivaled even the naturally gifted Karma Akabane.
While Nagisa may not be the strongest fighter in Class 3-E, he possesses an uncanny ability to conceal his presence and take out enemies with surgical precision. Under Korosensei’s guidance, he grew from an insecure boy who doubted his capabilities to an expert assassin capable of eliminating his opponents in the blink of an eye. Furthermore, he has one of the most compelling character arcs in the series, making him one of the most memorable aspects of Assassination Classroom.
6) Esdeath (Akame Ga Kill!)
The big bad of Akame Ga Kill! – Esdeath, is one of the few anime characters who could make you feel both terrified and strangely captivated at the same time. She is unnaturally strong, whose very existence screamed danger for anyone – no matter how strong they were.
Unlike some anime villains who at least pretend to have a noble goal or a tragic backstory, Esdeath is evil simply for the sake of it. Moreover, she’s fully aware of how despicable and terrifying she is—and loves every second of it. It’s hard to deny that she stole the whole show, as she even became one of the most problematic yet captivating characters in anime.
Esdeath’s striking blue hair, ice-based powers, and overall sadistic personality made her an iconic and unforgettable part of Akame Ga Kill!. She’s incredibly powerful, ruthless, and completely unhinged when it comes to her twisted view of love. She’s certainly not someone you would want on your bad side. That said, having her on your good side wouldn’t be any better either – Tatsumi can probably vouch for that.
5) Rin Okumura (Blue Exorcist)
Rin Okumura from the Blue Exorcist anime is pretty much the definition of chaotic energy – he’s loud, reckless, and constantly gets into fights. He’s also the son of the literal Satan, due to which he starts the series feeling completely lost and conflicted. However, Rin does not run away from his demonic heritage. He also doesn’t embrace his heritage and become his father’s rightful successor—instead, he chooses to use his powers to fight back.
As for his personality, Rin is fiercely loyal, protective, and supportive of his friends. However, he can also be reckless, impulsive, and downright dense in certain situations. That said, being the son of Satan himself and still managing to be an endearing and lovable character is no small feat. Moreover, his dark blue hair, paired with matching blue flames, makes him one of the most visually striking and iconic anime protagonists to ever exist.
4) Grimmjow Jaegerjaquez (Bleach)
Grimmjow Jaegerjaquez from Bleach is everything a villain should be – arrogant, brash, rude, with excessive bloodlust and a love for battle. He’s the shining example of someone who fights just for the thrill of it and refuses to back down even when he’s on the losing end.
He hates to be looked down upon and is driven by an unhealthy obsession with being stronger than others. That said, he does have his morals when it comes to fighting others, as seen when he refused to fight an injured Ichigo and gave him a chance to recover, as he wanted to fight him at full strength. Grimmjow certainly made Bleach a lot more fun to watch, with his signature spiky blue hair further elevating the coolness of his character design.
3) Hinata Hyuga (Naruto)
Early in the series, most people viewed Hinata as the “shy girl who had a crush on Naruto”. However, by Naruto: Shippuden and even the latter half of the original series, she proved that she was much more than that. From standing up to Neji in the Chunin Exams arc to charging at Pain in Shippuden, Hinata became the symbol of resilience and unwavering determination—much like Naruto.
In both cases, Hinata knew she couldn’t possibly win against her opponent. Regardless, she refused to back down, even when faced with overwhelming odds. Undoubtedly, her character arc is one of the best-written in the series. Moreover, her love for Naruto wasn’t simply because of how much she admired him—it was about her finding inspiration from someone who refused to let the world break him, an aspect of her character that made her a fan-favorite.
2) Bulma (Dragon Ball)
Dragon Ball‘s Bulma is an original blue-haired icon of anime. Before Dragon Ball became recognized for hyped-up transformations and fights that broke the Internet, Bulma was one of the series’ most important characters. In fact, she’s one of the cornerstones of the series because Bulma was the one who introduced Goku to Dragon Balls.
Bulma is widely regarded as one of the most iconic characters to ever exist, and for good reason. While others were punching each other and destroying entire planets with their battles, she built time machines, spaceships, and other genius inventions that made her stand out as one of the smartest Dragon Ball characters of all time. However, her most significant feat by far was somehow managing to tame Vegeta, which is arguably more impressive than being able to destroy entire galaxies.
1) Rimuru Tempest (That Time I Got Reincarnated as a Slime)
Rimuru Tempest is a god – and that’s not even an exaggeration. At the beginning of That Time I Got Reincarnated as a Slime, Rimuru was just a blue blob of slime. That said, they quickly evolved into one of the most overpowered isekai anime characters.
Rimuru’s absorption ability is simply ridiculous – it allows them to absorb the abilities, skills, and the very essence of other beings. It’s also what made them evolve from a weak slime to a demon lord-level threat in record time.
Unlike most overpowered isekai protagonists Rimuru has a compelling personality and character arc. They’re not outrageously overpowered just for the sake of it – their journey to the top felt earned. They are kind and strategic, and they care about building a better world for everyone. However, they’re quick to ditch their usual calm and composed demeanor when genuinely angered.
Conclusion
Anime characters with blue hair are undoubtedly some of the most impactful characters. They always leave a certain impression on fans, no matter how major or minor their role may be in the story – with the characters of this list being the perfect example of that.
