Manga is an influential form of art that combines intricate illustrations with captivating, often incredibly unique stories. When a manga becomes a hit, readers naturally wonder how the scenes will play out in animation, and that's how the idea of a TV series usually takes shape.
But here’s an interesting twist, some of the most successful anime aren’t based on manga at all! Instead, they are original creations first seen in anime format. If you're curious to find out which anime made a huge impact without being based on manga, keep reading to discover these amazing titles.
Code Geass
Code Geass: Lelouch of the Rebellion, an original anime created by Sunrise, is set in a futuristic Japan controlled by the Holy Britannian Empire. Lelouch Lamperouge, a prince of the empire, is exiled to Japan—a big mistake for his enemies, as he gets fueled by hate and gains the power to command anyone with a single glance from the mysterious C.C.
Written by Ichiro Okouchi and directed by Gorou Taniguchi, the series is beloved by fans who enjoy genius protagonists always two steps ahead. Its popularity led to several manga adaptations, including alternative versions and expanded content.
Puella Magi Madoka Magica
Puella Magi Madoka Magica is a dark fantasy series by Studio Shaft that redefined the magical girl genre in the most impactful way. A story about cute magical girls saving the world from witches shouldn’t have such a lasting effect, yet it continues to influence fans to this day.
Since its debut, the series has inspired numerous anime that blend adorable visuals with dark, often sinister stories. Even without a manga to draw from, Puella Magi Madoka Magica continues to produce new content, including the upcoming film Puella Magi Madoka Magica: Walpurgisnacht: Rising, set to release in 2025.
Fooly Cooly (FLCL)
FLCL is an original anime that follows the surreal life of Naota Nandaba and his chaotic journey of self-discovery, which takes a wild turn when he meets an eccentric woman on a Vespa. Known for its energetic pacing and unforgettable soundtrack, the series began as a six-episode OVA but has since expanded into an anthology with five seasons, along with a light novel and manga adaptation.
Though it’s often described as a "pure acid trip" with scenes that are hard to fully understand at first, the show ultimately tells a coming-of-age story rich in symbolism, capturing the messy, confusing, and transformative experience of growing up.
Tengen Toppa Gurren Lagann
Tengen Toppa Gurren Lagann, an original mecha anime from studio Gainax, ran for just 27 episodes, but each one takes viewers on an unforgettable adventure. It's hard to believe that the series wasn’t based on a manga.
In a world where humans are forced to live underground, oppressed by the Beastmen who rule the surface, Simon and Kamina struggle to find hope. Things change drastically when Simon discovers Lagann, a one-of-a-kind mecha with drills strong enough to tear through enemy machines. This discovery starts a rebellion that sets Simon and Kamina on a path to challenge the Beastmen and fight for a future beyond the surface.
Psycho-Pass
Psycho-Pass, created by the writer behind Puella Magi Madoka Magica, follows the story of Akane Tsunemori, an idealistic young woman who joins a police force that tracks down individuals with criminal intent before they can act. This is made possible by the Sybil System, a technology that scans people's mental states.
Set in a cyberpunk world, the series explores mature themes that captivated viewers, but it’s the show’s sharp storytelling, examining the complex balance between morality and justice, that made it an instant favorite. Its success quickly led to a manga adaptation, further proving the show's popularity.
Ano Hi Mita Hana no Namae wo Bokutachi wa Mada Shiranai (Ano Hana)
It began as a concept by screenwriter Mari Okada, brought to life through the direction of Tatsuyuki Nagai. Ano Hana has rightfully earned the title of “one of the saddest anime series,” but fans also remember it for its beautiful art, complex characters, and melodramatic music that tugs at their hearts, especially after completing the series.
The story follows the "Super Peace Busters," a group of childhood friends who grew apart after the tragic death of Menma. Five years later, Menma's spirit appears, seeking their help to fulfill her final wish. The series also inspired a film adaptation that serves as an epilogue, though it was not as well-received as the original series.
Kill La Kill
Studio Trigger’s first original anime series, Kill La Kill, follows Ryuko Matoi on her relentless quest to uncover the truth behind her father’s murder. Her journey takes her to Honnouji Academy, a school dominated by a student council wielding powerful uniforms known as Goku Uniforms.
Released in 2013, it quickly stood out as the wild and out-there anime of the year. While some thought it was way too raunchy for TV, it still managed to gather a loyal fanbase and is remembered fondly for its insane energy, sharp humor, and eye-popping visuals.
Paranoia Agent
Paranoia Agent is a psychological series by the legendary Satoshi Kon, who is known for his mind-bending storytelling. If you’ve seen his other works, you know you’re in for a thrilling ride. The story focuses on various Tokyo residents and their encounters with a mysterious juvenile figure known as Shounen Bat.
Each episode focuses on a different character, gradually unraveling the mystery of Shounen Bat while exploring deeper themes of mass paranoia and societal pressure. Satoshi Kon's other original masterpieces, such as Perfect Blue, regarded as a spiritual sibling to Paranoia Agent, and the visually stunning film Paprika, showcase his unmatched ability to blur the lines between reality and illusion, leaving a lasting impression on anyone who watches them.
Cowboy Bebop
One thing many original anime have in common is their short runs, and Cowboy Bebop is no exception. Fans have mixed feelings about director Shinichiro Watanabe’s decision to craft an ending too complex for a sequel. Still, Cowboy Bebop stands out as an experimental gem, with every carefully written episode offering glimpses of the story's final outcome.
The series combines elements of sci-fi, noir, and Western genres, delivering gripping action sequences, intriguing characters, and a jazzy soundtrack that ties it all together. While a Netflix live-action adaptation was produced, it received poor ratings and was ultimately discontinued.
Neon Genesis Evangelion
This classic mecha anime redefined the genre when it debuted as a TV series from the now-inactive Studio Gainax. Instead of following traditional mecha storylines, Neon Genesis Evangelion surprised viewers with its focus on deeply flawed teenage pilots and psychological themes.
Though its groundbreaking narrative earned widespread recognition, some scenes stirred controversy. Despite this, the series, originally not based on a manga, remains one of the most significant mecha anime of all time.
