Some of the most gripping anime out there are built around monsters: the creatures lurking just outside the walls, the demons that need slaying, the things that turn ordinary people into something else. Whether the monster is the enemy, the hero, or a little of both, these shows know how to keep you hooked.
Here are my picks for the best anime about monsters, leaning toward the monster-slaying side of the fantasy genre. Some are grim and bloody, others have real heart, and a few have both.
Monster-Slaying Anime Worth Watching
No strict ranking here, just shows I think do the monster thing especially well. A quick heads-up: a couple of these get very brutal, and I will flag those as we go.
Grimgar, Ashes and Illusions
Grimgar drops a group of young people into a dark, medieval world with no memory of how they got there or who they used to be. To eat, they have to join the Reserve Army and start killing the creepy creatures around their town.
- A group of amnesiac strangers fighting to survive in a fantasy world
- Low-level rookies taking on goblins, kobolds, and worse
- A grounded, melancholy take on the adventurer life
Noragami
Noragami follows Yato, a minor god who takes any odd job going while dreaming of his own shrine. When real trouble shows up, he fights the Ayakashi, ugly phantoms that feed on human fear and despair.
- A broke, self-styled “delivery god” who battles monsters on the side
- Ayakashi that prey on people’s darkest emotions
- Backed by his partners Hiyori, a half-phantom girl, and Yukine
- A great mix of comedy, action, and surprising heart
Goblin Slayer
Goblins might sit near the bottom of the monster pecking order, but Goblin Slayer makes them terrifying. Its grim, single-minded hero exists to do one thing: wipe out every goblin he can find.
- A stoic adventurer obsessed with exterminating goblins
- A dark backstory fueling his cold thirst for revenge
- A deliberately bleak spin on classic fantasy quests
Kabaneri of the Iron Fortress
Kabaneri imagines a steam-powered world overrun by the Kabane, zombie-like creatures with iron-armored hearts that turn anyone they bite into another monster. Survivors huddle behind walls and travel by armored train, which only delays the inevitable.
- A steam-era zombie apocalypse from the team behind Attack on Titan’s early seasons
- Kabane that spread their curse with a single bite
- Ikoma, a young engineer who builds a weapon to pierce their iron hearts
- He ends up a half-Kabane hybrid himself in the process
Claymore
Claymore is set in a world preyed on by Yoma, shape-shifting demons that pose as people and eat them. To fight back, a shadowy organization breeds half-human, half-Yoma warrior women, each of them wielding a huge claymore sword.
- Half-human warriors hunting flesh-eating shapeshifters
- Follows Clare, ranked the weakest of her generation at number 47
- Always at risk of losing herself and “Awakening” into a monster
- Heavy themes of identity, humanity, and sacrifice
Parasyte: The Maxim
Parasyte takes a different angle on monsters. High schooler Shinichi gets infected by an alien parasite, but instead of taking over his brain, it ends up stuck in his right hand. Now the two have to share one body and fend off the other parasites picking off humans.
- An alien invasion told through one very strange roommate situation
- Shinichi and his hand-bound parasite forced to cooperate
- Other parasites hiding inside ordinary people
- A smart, gory look at what really counts as a monster
Chainsaw Man
Chainsaw Man blends brutal action with pitch-black comedy. Denji is a broke teenager hunting Devils to pay off the debt his late father left with the yakuza, with only his little chainsaw-dog Devil, Pochita, for company.
- A down-on-his-luck kid killing Devils just to survive
- Pochita, a loyal dog-shaped Chainsaw Devil
- A yakuza betrayal that changes everything
- Denji reborn as a chainsaw-wielding human-devil hybrid
Dororo
Dororo tells the story of Hyakkimaru, a young ronin born without most of his body because his father struck a bargain with demons. He travels feudal Japan with a young thief named Dororo, hunting the creatures that hold his missing pieces.
- A swordsman reclaiming his stolen body one demon at a time
- Fitted with hidden blade prosthetics in place of his lost limbs
- A road-trip story of revenge and slowly regained humanity
- Based on a classic 1960s manga
Berserk
Berserk is one of the darkest, most violent stories anime has ever produced. It centers on Guts, a hardened mercenary with a horrific past, carving his way through a world crawling with demons and worse.
- A brutal dark-fantasy epic built around one scarred warrior
- Everything from trolls to nightmarish demonic apostles
- An unflinching, blood-soaked tone from start to finish
Attack on Titan
Attack on Titan opens with humanity penned behind enormous walls, hiding from the Titans, giant humanoid creatures that devour people for no clear reason. What starts as a survival story grows into something far bigger and stranger.
- Towering, man-eating Titans besieging the last of humanity
- Soldiers fighting back with gear that lets them fly between rooftops
- Intelligent Titans pulling strings behind the scenes
- A modern classic, divisive ending and all
Jujutsu Kaisen
Jujutsu Kaisen turns negative human emotion into literal monsters called Curses. Ordinary student Yuji Itadori gets pulled into this hidden world after swallowing a cursed relic to save his friends, binding a powerful Curse to his own body.
- A secret world of sorcerers fighting Curses born from fear and anger
- Yuji as the unwilling vessel for the King of Curses, Sukuna
- Training at a hidden school for Jujutsu sorcerers
- Slick, kinetic fights with a great cast
Demon Slayer
Demon Slayer follows Tanjiro Kamado after a demon slaughters his family and turns his little sister, Nezuko, into a demon herself. Refusing to give up on her, he joins the Demon Slayer Corps to find a way to make her human again.
- A kind-hearted boy hunting demons to save his sister
- Nezuko, a demon who fights to hold on to her humanity
- Gorgeous, intense sword-and-demon battles
- One of the most popular anime of the last decade
A Few Monster Anime Facts I Like
A handful of extras for the monster fans:
- A lot of these creatures come straight from Japanese folklore. The “ayakashi” spirits of Noragami and the “oni,” the ogre-like demons behind shows like Demon Slayer and Dororo, are ideas that go back centuries.
- Attack on Titan grew into a global phenomenon, with its manga selling well over 100 million copies worldwide.
- Berserk’s creator, Kentaro Miura, drew the series for more than three decades. He died in 2021 with the story unfinished, and a close friend has since continued it from his notes.
That is my pick of the best anime about monsters, whether you want grim and gory or something with a bit more heart. Which monster anime would you add to the list? Let me know in the comments.
