Since the late 1990s, the global anime and manga industry has operated under the long shadow cast by Eiichiro Oda’s One Piece. Its unprecedented blend of epic world-building, charismatic characters, and enduring narrative has established a benchmark for success that many have chased but none have matched. Over the decades, numerous shonen series have been positioned, either by editorial push or fan expectation, as potential successors to the throne. While many found their own success and dedicated fanbases, the quest to become “the next One Piece” has proven a near-impossible challenge.
The Unattainable Benchmark: What Defines a One Piece-Level Phenomenon
The ambition to replicate the success of One Piece is understandable. It represents the pinnacle of serialized storytelling in the shonen genre: a series that has maintained consistent quality, fan engagement, and cultural relevance for over two decades. However, this phenomenon is not merely a product of a single winning formula. It is a confluence of intricate world-building that rewards long-term investment, a vast and beloved cast of characters, a unique tonal balance between high-stakes drama and absurdist comedy, and a thematic core of freedom and friendship that resonates globally. Attempting to capture this alchemy often leads to imitations that, while competent, lack the singular vision and depth that make Oda’s work enduring.
Toriko: The Heavyweight Contender That Couldn’t Sustain the Hype
In the early 2010s, Toriko was marketed aggressively as part of a “new big three” alongside One Piece and Dragon Ball in crossover specials. Its creative world, based on gourmet ingredients and superhuman food hunters, held significant promise. The initial editorial push from Shueisha was substantial, aiming to cement the muscular protagonist as a new pillar of Weekly Shonen Jump. For a time, it worked, generating solid sales and anime adaptation.
However, Toriko ultimately failed to break into the global mainstream with the same force. The story was rushed toward a conclusion, leaving a sense of unexplored potential. It serves as a prime example that massive marketing campaigns and publisher favor cannot manufacture the organic, long-term connection with a global audience that One Piece cultivated over years. The audience, not the boardroom, crowns the king.
Fairy Tail: Commercial Juggernaut, Narrative Shortfall
Hiro Mashima’s Fairy Tail, with art style reminiscent of Oda’s and a focus on a guild family of wizards, quickly captured a massive audience. Its commercial success was undeniable, selling millions of volumes and sustaining a lengthy anime run. For many, it became a gateway into the shonen genre, celebrated for its emphasis on friendship and explosive, emotional battles.
Yet, as the story progressed, criticisms mounted regarding its narrative consistency and power scaling. The balance between its lighthearted tone and the serious stakes of its conflicts often tipped, leading to resolutions that felt unearned to some critics. While it secured a legacy as a beloved and successful series in its own right, it could not achieve the narrative complexity and meticulously planned foreshadowing required to be considered a true successor to One Piece‘s epic throne.
The Challenge of Sustaining a Grand Narrative Vision
One of the most difficult aspects of One Piece to replicate is its long-form narrative cohesion. Oda planted seeds hundreds of chapters in advance, creating a living, breathing world that feels vast yet interconnected. Many series that start with grand ambitions struggle to maintain that level of detail and planning, often collapsing under their own weight or simplifying their lore.
MÄR: A Pioneering Isekai That Lacked Lasting Depth
MÄR arrived before the isekai genre became oversaturated, transporting a boy to a fairy-tale world where magical weapons called ÄRMs dictated power. It featured a classic underdog protagonist and a creative combat system, earning a central spot in Shonen Sunday. Initially, it held promise as a contender.
Today, it is rarely discussed among genre pillars. The story lacked a strong, underlying mythology to sustain interest beyond its initial run. Unlike One Piece, where re-reads reveal new layers, MÄR relied on a straightforward narrative that quickly exhausted its premise. An interesting power system alone could not carry a story that lacked deeper thematic substance.
Nanatsu no Taizai: The Meteoric Rise and Precipitous Fall
The Seven Deadly Sins (Nanatsu no Taizai) experienced a phenomenal ascent, even surpassing One Piece in weekly sales in Japan at its peak. Its Arthurian-inspired world and group of legendary knights with dark pasts offered a fresh take on fantasy. The charisma of Meliodas and his companions was potent, and the mysteries surrounding them drove intense engagement.
However, the narrative later became mired in convoluted plot twists and an overemphasis on melodramatic romantic subplots that diluted its core appeal. The decline in animation quality for later anime seasons further damaged its reputation. It demonstrated that a position at the top is precarious; without rigorous maintenance of both narrative and visual quality, even giants can falter, leaving behind a mixed legacy rather than an enduring one.
Series That Carved Their Own Path Instead
Some series burdened with the “next One Piece” label ultimately found greater success by diverging from that path and establishing a unique identity. Their struggles highlight that direct comparison can be a disservice to a work’s individual merits.
Black Clover: From Derivative Underdog to Respected Survivor
Black Clover‘s debut was met with intense skepticism due to its perceived reliance on tropes from Naruto and One Piece, compounded by an anime adaptation criticized for its protagonist’s shrill voice. Many predicted a short-lived run.
Through sheer persistence and gradual refinement of its story and characters, Black Clover earned a respected place in the shonen landscape. It evolved into a solid, dependable series with a passionate fanbase. Yet, it remains a “great shonen” rather than a global “phenomenon.” Factors like inconsistent animation and genre fatigue have prevented it from reaching the absolute zenith, proving that arriving later in a saturated market presents its own unique hurdles.
World Trigger: The Tactical Masterpiece That Prioritized Strategy Over Hype
World Trigger is often hailed as one of the most intellectually rigorous series in Shonen Jump, featuring a combat system where strategy, teamwork, and resource management trump sheer willpower. Its premise of defending against alien invaders through tactical warfare presented a bold, cerebral alternative to typical shonen battles.
Paradoxically, its greatest strength became its commercial limitation. The intense focus on tactical detail resulted in a deliberately slow narrative pace, with lengthy training arcs and a large ensemble cast. This density, while rewarding for dedicated fans, created a barrier to the explosive, broad-based popularity required to reach One Piece-level status. It is a masterpiece of game design in narrative form, but not a universal adventure.
Radiant: The International Heir to the Adventurous Spirit
As a French “manfra” adapted into anime by a Japanese studio, Radiant stands apart. Creator Tony Valente openly cites One Piece as a major inspiration, evident in its floating island world and its tackling of heavy social themes like racism within a vibrant adventure framework. It was heralded as a potential international successor to the shonen adventure spirit.
While the manga is critically acclaimed for capturing Oda’s spirit of adventure and thematic depth, its status as a non-Japanese production with a different publication rhythm places it outside the direct competitive sphere of Jump’s flagship titles. Radiant powerfully demonstrates the universal appeal of One Piece‘s core ideals, while also highlighting the significant challenges in translating that success across different cultural and industry contexts.
Beelzebub: The Absurdist Comedy That Lost Its Edge
Beelzebub brilliantly fused delinquent school life with the supernatural, following a tough guy forced to raise the Demon King’s son. Its comedy was sharp, absurd, and highly effective, carving out a unique niche in Jump. The premise allowed for both hilarious gags and intense battles, suggesting vast potential.
Its premature cancellation, however, left numerous plot threads dangling. The rushed ending fostered a sense that the series was a victim of an editorial system seeking to force stories into a predefined mold of success. Beelzebub proved that attempting to become the next big hit by focusing on generic shonen battles, rather than nurturing its unique comedic voice, can be the fastest way to lose what makes a series special.
The journey of these eight series reveals less about their individual failures and more about the unique, unrepeatable phenomenon that is One Piece. The pursuit of a successor often overlooks a crucial truth: lasting impact in storytelling rarely comes from imitation. It springs from a singular vision executed with consistency over time. While the shadow of the Straw Hat pirates is long, it has also inspired a generation of creators to build their own worlds, tell their own stories, and find their own audiences. In doing so, they enrich the anime landscape, not by replacing a king, but by expanding the kingdom.
