Future Boy Conan
Directed by Hayao Miyazaki in his Early Years
Before achieving worldwide fame, Hayao Miyazaki proved his directing skills with popular television series. One notable example is Future Boy Conan, which aired in 1978 and was later shown in several countries around the world.
Though short with just 26 episodes, this anime tells a powerfully memorable story. Set in a future Earth devastated by disaster, it follows a young boy born after the apocalypse as he seeks his purpose. His life is turned upside down when he meets a girl, after believing he only had his grandfather. The story, much like a classic Hayao Miyazaki film, depicts a world struggling to rebuild and offers a surprisingly thoughtful and engaging plot.
Yu-Gi-Oh!
The Most Famous Card Game in a Legendary Anime Adaptation
RetroCrush is helping keep the classic anime Yu-Gi-Oh! popular by streaming it for free and showing it on its FAST channel. First airing in 1998, this show is a beloved example of the monster-summoning battle genre.
Yugi Mutou’s life turned upside down when he solved the Millennium Puzzle and unleashed the Shadow Games. Not only did this bring forth the spirit of Yami Yugi, but it also led to Yugi finding a loyal group of friends. Once a target of bullies, Yugi now embarks on incredible adventures – and this is only the start of his story.
Magic Knight Rayearth
Clamp’s Magical Warriors Saving a Fantasy World
We’ve discussed Magic Knight Rayearth before, and it remains a landmark magical girl series from the 90s, especially for its use of the ‘isekai’ (another world) concept. The creators, Clamp – also known for manga like X and Cardcaptor Sakura – showed that magical girl stories didn’t have to follow typical formulas.
The story starts when three high school students – Hikaru, Umi, and Fuu – find themselves in a magical world after a visit to Tokyo Tower. This seemingly ordinary trip, a common experience for many Japanese students, unexpectedly launches them into an incredible adventure. Despite being strangers from different schools, they quickly become close friends and work together to fight for what’s right.
All Purpose Cultural Cat Girl Nuku Nuku
An Android with the Appearance of a Schoolgirl Receives a Cat’s Brain
I’ve been following Yuzo Takada’s work for a while now – he’s the creator of manga like 3×3 Eyes and Blue Seed, both of which were adapted into anime. But I recently discovered another anime based on his work that really stood out: All Purpose Cultural Cat Girl Nuku Nuku. It puts a really unique spin on the idea of creating an android, and it’s definitely worth checking out.
This anime features Nuku Nuku, an android cat girl created by scientist Kyusaku Natsume. The story blends comedy and action as Natsume clashes with the company that built Nuku Nuku’s body. While not a standout in its genre, it’s enjoyable thanks to its charming characters and humor, and with only 14 episodes, it’s a quick watch. It’s different from classics like Dr. Slump and Astro Boy, but offers its own unique appeal.
Boogiepop Phantom
The Perfect Anime for a Binge-Watching Session with a Quality Psychological Thriller
I remember watching Boogiepop Phantom back in the early 2000s and being struck by how different it was from other anime at the time. It really felt like a turning point, showing that Japanese animation was ready to tackle more complex and thoughtful stories. It was based on Kouhei Kadono’s novels and just offered something truly unique.
This anime stands out with its mature, often grim storylines and a visual style that’s a stark departure from typical 90s animation. Each episode tells a different part of the larger story, offering multiple perspectives on seemingly unconnected events. While it was challenging to follow the plot with weekly releases, binge-watching all 12 episodes makes the narrative much clearer. The anime centers around a series of unsettling incidents – murders and disappearances – potentially linked to a mysterious figure associated with death, delivering a truly thrilling experience.
Key the Metal Idol
A Robot Girl Who Wants to Become Human by Becoming an Idol
Though it inspired shows like Serial Experiments Lain, Key the Metal Idol is a bit of a complicated anime. Its 15 episodes build a complex mystery and storyline that could rival even some popular live-action TV shows.
The anime centers around Tokiko Mima, a robotic girl whose scientist father continually upgrades her as she ages. Tokiko believes she needs to make 30,000 friends to become truly human, and she hopes to achieve this by becoming a popular idol. While the story begins with this simple goal, it quickly evolves into a complex mystery that challenges initial assumptions. The anime’s conclusion proved controversial and sparked a lot of discussion among viewers.
Beelzebub
An Anime From Shonen Jump, Full of Action and Comedy
The anime Beelzebub first aired on TV in 2011. It was produced by Pierrot+ and based on a manga by Ryuhei Tamura. While it didn’t quite reach the level of other popular action series of that era, it was an enjoyable show with a total of 60 episodes.
Tatsumi Oga is a troublemaking student who suddenly has a very unusual job: babysitting the son of the Demon King! It’s a crazy situation that quickly leads to lots of exciting battles and fights. Though he’s not happy about it at first, Tatsumi is soon forced to take on the responsibility of caring for the child.
Hajime no Ippo
A Perfect Boxing Anime Even for Those Who Don’t Like Boxing
Hajime no Ippo, also called Fighting Spirit, is a boxing anime series inspired by the classic Ashita no Joe. However, it offers a fresh take on the genre with updated visuals and a protagonist who’s quite different from its predecessor.
Widely considered a landmark manga, and with its anime reaching legendary status, this is a story everyone should experience. It follows Ippo Makunouchi, who turns to boxing after being bullied. What follows is an inspiring tale of personal growth and thrilling matches. This series offers a uniquely uplifting take on the world of boxing and is best enjoyed from start to finish.
Saint Tail
A Thief Who Acts as a Magical Girl and Has a Strong Code of Honor
Megumi Tachikawa became well-known by cleverly blending the magical girl genre with stories about thieves. Her manga, Saint Tail, was particularly successful and was later turned into a 43-episode anime series, now available on RetroCrush.
Meimi Haneoka is a student with a secret: she’s a nighttime hero inspired by her parents – a thief and a magician. Instead of stealing, she recovers stolen goods and returns them to their rightful owners. But she’s not operating without a challenge; a young detective is determined to unmask her, so Saint Tail must be extra cautious as she continues her missions.
Nadia: The Secret of Blue Water
Great Adventures in One of the Best Anime of the 90s
Nadia is a special anime created by a fantastic team. It brings together the talents of Hideaki Anno, the creator of Neon Genesis Evangelion, Hayao Miyazaki, who developed the core concept, and the inspiring stories of Jules Verne. The combination is truly wonderful, and it’s a great show to watch on RetroCrush if you get the chance.
This anime series originally aired in Japan from 1990 to 1991. It became available in the United States through VHS tapes, and was broadcast on television in several European countries. The story centers around Jean, a young inventor, and his friendship with the enigmatic Nadia. Together, they experience thrilling and perilous adventures inspired by the works of Jules Verne. With 39 episodes, it’s considered a classic anime from the early 1990s.
