Let’s face it: in anime, demons are what bring on the mayhem, the complexity, the feels. There’s something about horned, fanged, hell-born characters that’s compelling—these characters are complicated, strong, emotionally exposed, and often a great deal more interesting than the supposed heroes. Whether they’re battling internal demons (literally), breaking down walls between dimensions, or just struggling to live in a world that finds them to be monsters, these characters flipped the script on what it means to be a demon.

10. Ariel – So I’m a Spider, So What?

Ariel is not your typical demon overlord. She’s strategic, heartbreaking, and wrapped up in the sort of moral gray areas that make your head ache. As the Demon Lord navigating a complex terrain of political intrigue and survival threats, she’s a testament that demons can do more than simply destroy the world—they can be cruelly strategic, emotionally wracked, and jarringly human. Her story is as layered as can be, and that’s what makes her stand out.

9. Rias Gremory – High School DxD

Rias trumps the chivalrous demon and makes it all tackily human. She’s poised, powerful, and as at home summoning circles of magic as she is dealing with a supernatural school club. But it’s her dedication and complexity that truly make her stand out. Sandwiched between the ancient family soap opera and the everyday high school chaos, Rias shows us that being a demon doesn’t have to come at the expense of your heart—or your wardrobe.

8. Sadao Maou – The Devil Is a Part-Timer!

What does one do when the Demon King loses his mojo and becomes a burger flipper in Tokyo? Pure genius. Sadao Maou’s descent from terror ruler to fast food worker is both laughable and strangely poignant. His fight to pay rent, use coupons, and rise through the corporate ranks while keeping his former life together makes him one of the most lovable demon characters around. Who knew world domination and customer support were so similar?

7. Ryomen Sukuna – Jujutsu Kaisen

Sukuna is terrifying in the best possible way. He’s not just a demon—he’s a curse who radiates menace, cruelty, and older-than-time energy. Living inside the main character, Yuji Itadori, Sukuna is a constant reminder of the danger that lurks just below the surface. Their tense coexistence has you on edge, because when Sukuna shows up, you know things are gonna get very dark, very fast.

6. Meliodas – The Seven Deadly Sins

Meliodas may appear to be your run-of-the-mill cheeky anime hero, but beneath his mischievous grin lies the tormented heart of a demon prince. Conflict between love, loyalty, and his tainted past makes his tale full of emotional complexity. Meliodas is a tale about his attempt to shatter the course of his fate and the expectations of his demon heritage. He’s a heartbreaker—and not due to his sword.

5. Rin Okumura – Blue Exorcist

Being the devil’s son isn’t so much a stroll in the park, and Rin Okumura finds out the hard way. With his signature blue flames and attitude, Rin’s struggle is one of forging his oath in a world that’s afraid of what he represents. He’s hot-headed (literally), passionate, and always attempting to show the world that there’s more to him than the circumstances of his birth. It’s ugly, it’s painful—and that’s what makes it gorgeous.

4. Hiei & Kurama – Yu Yu Hakusho

Yu Yu Hakusho provided not only one, but two of the most iconic demon characters ever that shaped an age. Hiei is the troubled bad boy with his intimidating stare and kill-or-be-killed demeanor, and Kurama is the quiet tactician with a sinister, fox-demon background. Combined, they add depth and charisma to a demon realm full of politics, power plays, and philosophical overtones. These two? Ageless.

3. Sesshomaru & Inuyasha – Inuyasha

Few fights are more emotionally charged than that of half-demon Inuyasha and his frosty full-demon brother Sesshomaru. Their endless push and pull is more than mere swords clashing—it’s a rich exploration of identity, pride, and familial scars that never fully close. Sesshomaru’s gradual character development from merciless loner to guardian is one of anime’s greatest, while Inuyasha’s battle with acceptance has us rooting for him every step of the way.

2. Akira Fudo – Devilman Crybaby

Akira Fudo’s evolution into Devilman is heartbreaking, gruesome, and utterly unforgettable. As a human host to a mighty demon, Akira is the ultimate hybrid—battling to save humans and demons alike from a world tearing itself apart. His tale is a naked, heartfelt gut check that poses tough questions regarding humanity, morality, and love. Few characters internalize conflict the way Akira does, and his journey is a freight train to the emotions.

1. Nezuko Kamado – Demon Slayer: Kimetsu no Yaiba

Nezuko is not only a fan favorite—she’s the soul of contemporary demon anime. Forced to be turned into a demon, Nezuko’s struggle to hold on to her humanity is nothing short of uplifting. Her relationship with Tanjiro is the heart of Demon Slayer, and her reserved strength, compassion, and fiercest loyalty redefine what it is to be a “monster.” No matter whether she’s battling demons or snuggled up in her traveling box, Nezuko is unforgettable. Hands down, a genre-bending icon.
