The 1990s were a notable decade for the manga industry, and shonen manga especially. Not only was manga in general starting to gain popularity in the West, but many of the tropes and conventions associated with the shonen demographic started in this decade, and many titles that originated in the 90s are still popular to this day.

Battle Shonen With Ghosts And Spirits

Running from 1998 to 2004, Shaman King is a classic battle shonen, complete with a tournament arc and non-stop action.

7 Rurouni Kenshin

A Hugely Influential Samurai Epic

It may be set in the Meiji era, but Rurouni Kenshin is a distinctly 90s series. The manga tells the story of Kenshin Himura, a wandering samurai trying to atone for his past. The series ran from 1994 to 1999 and soon became one of the best-selling manga of all time.

Rurouni Kenshin became the inspiration for other shonen series like Naruto and Gintama, and Kenshin even inspired Demon Slayer's protagonist. Additionally, it's an early example of a shonen series that also attracted a female audience due to its character designs and romantic elements.

6 Trigun

The Story Of A Famous Pacifist Gunman

While only the original series is considered a shonen, Trigun is still one of the most influential titles in the genre. Following the adventures of a mysterious man known as Vash the Stampede, Trigun is a surprisingly deep look at human morality and the philosophy of pacifism.

The manga received an anime adaptation in 1998, but it went in a different direction than the original series. Trigun proved to be so enduring as a series, however, that a remake called Trigun Stampede was released in 2023, with a completely different look and feel.

One Of The Most Renowned Isekai

Inuyasha serves as an early example of an extremely popular anime/manga/light novel genre - isekai.

There, she takes it upon herself to collect pieces of a magical jewel she accidentally shattered with the help of a half-demon named Inuyasha.

Inuyasha is one of those classic series that's loved to this very day, inspiring many anime adaptations (including a sequel series in 2020), video games, drama CDs, stage plays, and a light novel.

Teenage Detectives, Martial Arts, And Angst

A classic manga with an anime adaptation that was a part of many fans' childhoods, YuYu Hakusho follows Yusuke Urameshi, a teenager who becomes a Spirit Detective after saving a child's life from an oncoming car. Blending supernatural elements, martial arts, and a dash of teenage angst, the series quickly became one of Shonen Jump's bestselling manga.

The Dark Tournament arc is perhaps the most famous arc in shonen history, and the series' staying power is further enforced by the 2023 live-action Netflix series.

3 Hunter x Hunter

Hunting Rare Beasts With A Private School Twist

Lightning struck twice for manga artist Yoshihiro Togashi, with both YuYu Hakusho and Hunter x Hunter being hugely successful shonen series. Gon Freecss, a young boy abandoned by his father, wishes to become a Hunter, an elite human capable of hunting rare beasts, locating treasures, and exploring mysterious locales. To reach his goal, however, he must pass the extremely high-stakes Hunter Exam.

2 One Piece

The Best-Selling Manga Of All Time

Considered one of the Big Three of classic battle shonen along with Naruto and Bleach, One Piece is the best-selling manga of all time, and even though its first chapter came out in 1997, its popularity hasn't faded in the slightest. The well-received live-action adaptation by Netflix in 2023 proves that.

1 Slam Dunk

Kicked Off Japan's Basketball Craze

The influence Slam Dunk has had over the years transcends anime and manga. It led to the increased popularity of basketball among Japanese youth in the 90s and Japanese-American basketball player J. R Sakuragi named himself after the series' protagonist. While the manga initially failed to break out of the Japanese market, it would soon go on to be the 6th highest-rated manga on MyAnimeList.

The incredibly realistic portrayal of basketball, an inspiring underdog story, and heaps of character development led to Slam Dunk being considered the greatest sports manga of all time.
