One Piece is pretty much considered the current monarch of the Shōnen adventure. Most of its mainstays, the Nakama Band, the Mysteries of the Forgotten World, and the Power Systems, are considered the pinnacle of their genres at this point, but what some fans may not know is that some classic series actually perfected these tropes.
These retro gems often delivered the same high-stakes emotional payoffs with significantly tighter pacing and narrative focus. Not having the luxury of a thousand episodes, these series needed to make every story beat count, leading to a sense of discovery that is concentrated in modern long-runners and can get lost in their pursuit of the story. These eight titles are the design that perfected the ensemble cast and enigmatic of ancient civilizations. From the harshness of space bounty hunters to the detailed political structures of other spaces, they provide the same sense of discovery as the Grand Line.
35 Best Anime on Crunchyroll Right Now (2026)
Crunchyroll's anime lineup is constantly growing. This guide highlights the best shows to watch right now in 2026.
Outlaw Star
It's a space western set in the future, where Gene Starwind and a motley crew are on a mission in the most high-tech ship in the galaxy, in search of the fabled “Galactic Leyline”. Similar to One Piece, it is based on the idea of a small crew hunting for a mythical treasure that will transform the world.
What it is more successful at is ship-to-ship combat and beauty. The grappler ships give battles a sense of emotion that the naval battles in One Piece tend to lack. The hunt for the Leyline is urgent and mysterious, and the ending is kept focused in a way that makes the treasure's distribution a reward and not held indefinitely.
Cowboy Bebop
Considered by many fans as the best anime of all time, this is a series about a group of bounty hunters struggling to survive in a colonized solar system. It reflects the found family element of the Straw Hats, with each member carrying a heavy burden in their past and trying to create a future together.
Cowboy Bebop approaches the dynamics of “Nakama” with much more emotional complexity and maturity. The relationships are demonstrated, not by shouting about the friendship, but by small gestures and by mutual silence. Its episodic quality allows one to immerse oneself in the character and make the inevitable resolution of their respective traumas feel deeply heartbreaking and irreversible.
35 Best Anime of the 90s, Ranked
The 1990s were a great time for anime, and several series from the era are still popular today. Here are the best anime from that decade.
Magic Knight Rayearth
Three girls are called to the world of Cefiro to become legendary magical knights and save the pillars of their world. The world building of this series rivals the Grand Line, where the sheer willpower of its inhabitants literally carves out the geography and power of their magical evolutions.
What it does a little better than One Piece are its thematic efforts and the turn of world history. Although Void Century is a slow burn, Rayearth makes a shocking revelation about the price of being a hero that recontextualizes the entire journey. A masterpiece of making a fantasy world appear beautiful, yet breathtakingly vulnerable.
Rurouni Kenshin
Set in the early Meiji period, it is the story of a former assassin trying to achieve redemption. It has the same interest in One Piece with the sins of the Father and how the past determines the militaristic struggles of the present, with Kenshin as the link between the two worlds.
The concept of a dark past for a main character is taken much more seriously in the series. The fact that Kenshin swore never to kill gives him tactical tension in battle that Luffy, with his proverbial hit harder strategy, doesn't often encounter. The political intrigue and “Kyoto arc” provide a formula of high-stakes Shōnen stories that has never been matched in its emotional resonance and historical grounding.

Nadia: The Secret of Blue Water
This maritime adventure is about a mysterious girl, a young inventor and a high-tech submarine in search of a lost civilization. This series has been openly described as a significant influence on One Pieceespecially in its treatment of ancient technology and its mysterious great treasure.
Nadia can afford to be more adventurous because the sense of danger is closer at hand. The secret behind “Blue Water” and its relationship to Atlantis is revealed in tight, suspenseful lines, without ten years of foreboding. It's a wonder to explore the ocean with a more nightmarish and leaner sci-fi approach that's truly epic.
Saint Seiya
This is a mythical series that tells the story of warriors who take power through their Cosmo to save the goddess Athena. It is the prototype for the modern power systems One Piecewhich revolves around the inner power and spiritual strength needed to beat seemingly unbeatable enemies.
What makes Saint Seiya stand out is the mythic scale and sacrifice. The battles resemble operas where the life and death of the entire universe hangs in the balance. The power system is more philosophically coherent than Haki, and the design of the armor gives it a visual progression so that every power-up is a significant story moment.
Tenchi Muyo! Ryo-Ohki
A young man accidentally frees a space pirate and learns that he belongs to an intergalactic royal family. It also features a disorganized “found family” of aliens and princesses, all living under one roof, and mixes space opera with domestic comedy in a way that feels very Straw Hat-esque.
The series treats the hidden lineage trope with greater elegance and timeliness. Not only does Tenchi find out about his past late in the series; it is something that has been a source of political conflict and character development. The scope of the Spacefaring Empires is more expansive and menacing than the World Government, offering true cosmic adventure and exploration.
The Twelve Kingdoms
A young girl is transported to a place inspired by Chinese mythology, where she must navigate the complex court politics and magical hierarchies to become a monarch. It can be seen as One Piece by Isekai due to its multi-layered world-building and tight internal logic.
It is incredibly competent in political world-building and geography. The way the kingdoms are organized, starting with the birth of the kings to how the provinces are governed, is like a real running society. The character development of Yoko, a coward who becomes a queen, is a deeper character transformation than most modern Shōnen, rooted in realism.
