12 Anime About Monsters

The biggest monster-slaying anime of the modern era. Tanjiro Kamado’s journey to save his sister Nezuko from being a demon, while joining the Demon Slayer Corps, became a global phenomenon. Mugen Train became the highest-grossing Japanese film ever made. The fight animation by Ufotable redefined what was possible in 2020s anime production.

The franchise size: Demon Slayer has fundamentally shaped how monster anime gets made now. The success of the show pushed every major studio to invest more heavily in animation quality for action sequences. The Hashira Training arc and Infinity Castle arc are still rolling out as of 2026.

The titans are some of the most disturbing monster designs in all of anime — massive, naked, smiling humanoids that exist to eat people. Eren Jaeger’s journey from terrified kid to Survey Corps soldier to something much darker carried one of the most ambitious storylines in modern anime. The final season ended in 2023 with one of the most-debated finales in anime history.

If you haven’t watched Attack on Titan, the answer is yes, even with the divisive ending. Yes.

Yuji Itadori swallows a cursed finger belonging to the ancient demon Ryomen Sukuna and ends up sharing his body with one of the strongest monsters in existence. Then he goes to monster-fighting school. Jujutsu Kaisen took the Demon Slayer-shaped hole in the late 2010s and 2020s and made it its own with sharper writing, denser worldbuilding, and the Gojo cult phenomenon.

The 2024-2025 sensation: Solo Leveling is the Korean manhwa-adapted anime that became one of the biggest hits of the post-Demon Slayer era. The story: gates open across the world, monsters pour out, “hunters” with magical abilities fight them. Sung Jinwoo, the world’s weakest E-rank hunter, gets a system that lets him level up like an RPG character. He becomes very, very, very strong. The action animation by A-1 Pictures is consistently top-tier.

If you want monster-hunting anime with explicit video game / dungeon mechanics, Solo Leveling is essential.

Tatsuki Fujimoto’s Chainsaw Man is the most unhinged modern shōnen, in the best way. Denji is a teenage devil hunter drowning in yakuza debt. His pet devil Pochita merges with him, turning him into a human-devil hybrid with literal chainsaws sprouting from his body. Then the actual plot starts, and it’s even weirder.

MAPPA’s 2022 anime adaptation was contentious among manga fans, but it’s gorgeously animated and worth watching. The Chainsaw Man movie (in production as of 2026) is highly anticipated.

The grandfather of dark fantasy monster anime. Guts, the “Black Swordsman,” wields a sword the size of a car and slaughters demons across a brutal medieval world. The 1997 anime adaptation is foundational. The manga (by the late Kentaro Miura) influenced everything from Dark Souls to Demon Slayer to half of contemporary shōnen.

Where to start with Berserk: The 1997 anime covers the Golden Age arc and is the best entry point. Skip the 2016 CGI adaptation entirely. The manga continues to be published in some form following Miura’s 2021 death, with his close collaborator Kouji Mori overseeing the continuation.

One of the smartest monster anime of the 2010s. Aliens called Parasites invade Earth and take over human hosts by replacing their heads. Shinichi’s invading Parasite, Migi, gets stuck in his right hand instead of his head, and the two have to coexist. The show asks genuinely hard questions about ethics, survival, and which species deserves to live.

Also: Netflix made a Korean live-action spinoff called Parasyte: The Grey in 2024, which is also excellent if you’ve finished the anime.

Content warning: Goblin Slayer is genuinely brutal. The opening of episode one is one of the most disturbing scenes in modern anime, depicting graphic violence including sexual assault. The show uses this to establish stakes and motivation, but it earned the series significant controversy on debut. If you’re sensitive to that content, this isn’t your anime.

If you’re fine with the tone, the actual show is a fascinating subversion of the fantasy adventurer trope. Goblins are usually low-level “tutorial” enemies in fantasy stories. Goblin Slayer treats them as the real threat they would actually be: organized, vicious, ruthless. The protagonist is the only adventurer who takes them seriously.

The OVA series that adapted Kouta Hirano’s manga more faithfully than the original 2001 anime. Alucard, the most powerful vampire in existence, works for the Hellsing Organization to hunt OTHER monsters — vampires, ghouls, and eventually, the literal SS-themed villains of Millennium. The Hellsing Ultimate animation is stylized to extreme levels, and Alucard is one of the most charismatic monster-hunter protagonists ever.

Yato is a minor god who runs a “delivery god” service for 5 yen per job. He hunts Ayakashi (spirits that feed on negative human emotions) with his teen sidekick Yukine and his human partner Hiyori. The show balances comedic god-of-fortune antics with surprisingly dark mythological action. Underrated and overdue for a third season.

Masaaki Yuasa’s 2018 Netflix anime adaptation of Go Nagai’s foundational 1972 manga. Akira Fudo merges with a demon and becomes Devilman, fighting other demons that are invading Earth. The show is brutally explicit, emotionally devastating, and one of the best-animated anime on any streaming platform. The 10-episode run barely lets up.

Devilman Crybaby ranks among the best Netflix original anime ever produced. If you want monster anime with serious artistic ambition, this is essential.

The 2019 reboot of Osamu Tezuka’s 1969 classic. Hyakkimaru’s father traded away 48 of his unborn son’s body parts to demons in exchange for power. Hyakkimaru, now grown and equipped with prosthetic blades, must hunt down each demon to reclaim what was stolen from him. Every demon slain restores another piece of his humanity.

The reboot’s animation, voice work, and pacing are all excellent. One of the best fantasy anime of the late 2010s.

Half-human, half-Yoma warrior women hunt shape-shifting demons across a medieval fantasy world. The Claymores are slowly transforming into the monsters they hunt, making every battle a balance of using just enough demonic power to win without losing themselves. Clare’s journey is one of the most underrated monster-hunter arcs in anime.

The 2007 anime didn’t get the manga’s full ending, but the existing 26 episodes are solid.

Made by the same team behind Attack on Titan and often called “AOT with zombies in steampunk Japan.” That description undersells it. The Kabane are a fast, intelligent zombie variant, and the protagonist Ikoma becomes a “Kabaneri” — a half-human hybrid who can fight them on equal terms. Beautiful action choreography from Wit Studio.

The slice-of-life monster anime. A group of strangers wake up in a fantasy world with only their names. They have to learn how to be adventurers from scratch — which means learning how to kill goblins for the first time, with all the trauma that involves. Grimgar treats monster-hunting not as adventure but as labor: dangerous, traumatic, and morally complicated.
