The most popular anime in the world are almost exclusively adaptations of manga and other material. Adaptations will always have built-in fanbases to help them take off, and in the case of manga, people can pick them up right from where their anime end, meaning they can stay engaged with the stories no matter how long it takes for their anime to come back, if they even do.

Anime adaptations have an undeniable appeal, but they’re hardly the only way to go. Every year, anime studios release just as many original anime as they do anime adaptations, if not more, and sure enough, there are plenty of incredible original anime that everyone needs to watch, even if there’s no source material to go along with them. A few original anime like that especially stand out, and whether they’re enduring classics or more modern hits, each one is plenty worth a try.

10 Zombie Land Saga

Anime Series By MAPPA; Directed By Munehisa Sakai

MAPPA’s Zombie Land Saga stars Sakura Minamoto, a girl who, after getting run over by a truck, awakens 10 years later as a zombie courtesy of the mysterious and eccentric Kotaro Tatsumi. To Sakura’s surprise, Tatsumi has revived her and six other girls to become an idol group popular enough to revitalize the dying Saga prefecture, and their quest to do so is filled with plenty of complications, even without the issue of them being zombies.

Zombie Land Saga is famous for keeping everything about its story a secret until its premiere, and because of that Zombie Land Saga’s marketing was the perfect way to draw people into a hilarious comedy with great music and engaging character drama. It’s one of the best MAPPA anime, by far, and with the movie set to premiere in 2025, there’s plenty more in store for fans old and new.

9 Paranoia Agent

Anime Series By Madhouse; Directed By Satoshi Kon

In Madhouse’s Paranoia Agent, an overworked character designer is suddenly assaulted while struggling to come up with a new character, and she tells the police that a rollerblading boy with a baseball bat attacked her. While the police initially assume she’s lying, more victims of the same boy, now dubbed “Li’l Slugger”, start cropping up, and what follows is an increasingly surreal exploration into the mystery behind Li’l Slugger’s actions.

Between its creative animation and direction and a story that’s as engaging as it is absurd, Paranoia Agent is a great short anime for how well its visuals complement a surreal story that rewards fans for paying attention to the smallest detail. Paranoia Agent was the only TV show made by legendary director Satoshi Kon, and for anyone who’s even so much as heard of his work, it’s an anime that can’t be ed up.

8 Code Geass

Anime Series By Sunrise; Directed By Goro Taniguchi

Between its engaging mystery and political storylines and how it boasts some of the best mecha-based action of any anime, Code Geass is a mecha anime that delivers on all fronts and is probably Sunrise’s best mecha anime after the Gundam franchise. The original anime is still iconic after almost 20 years, and with the franchise finally coming back with new content in recent years, now’s the best time to get into it.

Five years later, one of those friends, Jinta, suddenly finds himself encountering Menma’s ghost, and to help her properly on to the afterlife, he and everyone else will have no choice but to confront their various traumas and make peace with each other and themselves.

Not only does Anohana boast incredible art and animation, but with its emotional and thoughtful writing, Anohana: The Flower We Saw That Day has some of the most heartwrenching and emotionally fulfilling writing of any anime, with its final big scene especially standing out as one of the best scenes in anime.

6 Puella Magi Madoka Magica

Anime Series By Shaft; Created By Gen Urobuchi

In Shaft’s Puella Magi Madoka Magica, after a chance encounter with a monster called a Witch, Madoka Kaname learns of the existence of magic and, of course, magical girls. Kyubey, the creature who oversees the magical girls, offers Madoka a chance to become one, herself, and help protect her home from Witches, and as Madoka ponders over the decision, she quickly discovers that being a magical girl is nowhere near as good as Kyubey first made it out to be.

Not only are the visuals some of the best in all of anime, but Puella Magi Madoka Magica’s dark and deconstructive take on the magical girl genre makes for deep and poignant writing from start to finish. It’s one of the best magical girl anime someone can watch, and that’s unlikely to change anytime soon.

While not as well-known as Shinichiro Watanabe’s other anime, especially not Cowboy Bebop, is an underrated masterpiece thanks to its incredible soundtrack and how well it succeeds at telling an emotional and all-around fun story from start to finish. Watanabe’s latest project, Lazarus, premieres soon, and anyone excited about it would be remiss not to watch Carole & Tuesday, as well.

4 Neon Genesis Evangelion

Neon Genesis Evangelion is one of the most iconic and influential anime of all time, and sure enough, Neon Genesis Evangelion’s great visuals and dark storytelling make for a wonderfully deconstructive anime that more than earns its stellar reputation. Whether it’s the original anime or the Rebuild of Evangelion tetralogy, there are few anime better to watch than Evangelion, and it’s just as great to watch now as it was 30 years ago.

3 Mobile Fighter G Gundam

Anime Series By Sunrise; Directed By Yasuhiro Imagawa

For the 13th Gundam Fight, Domon Kasshu enters as the representative of Neo-Japan not just to win the tournament, but to get revenge against his traitorous brother Kyoji and uncover the truth behind the mysterious and dangerous Dark Gundam.

While the hammy, wuxia-inspired story puts G Gundam firmly in the super robot genre, a stark contrast to how Gundam usually sticks to the real robot genre it helped pioneer, the sincerity in Mobile Fighter G Gundam’s writing makes all of its goofiness work perfectly from start to finish. Despite all odds, G Gundam has one of the best stories of any Gundam project, and any fan of the franchise should certainly give it a try.

Between its gorgeous visuals and animation and how well the writing balances comedy and drama, Cowboy Bebop is one of the best anime to watch on both a visual and narrative level, a fact that’s as true now as it was almost 30 years ago. Cowboy Bebop is often regarded as one of the best anime of all time, if not the best, and overall, it’s easy to see why.
