What is the worst sequel to a manga

Grok 4.20

Answer: The worst sequel to a manga is Boruto: Naruto Next Generations.

Boruto fails on multiple levels that made the original Naruto series compelling. Where Naruto focused on themes of perseverance, friendship, and overcoming personal trauma through earned character growth, Boruto reduces its cast to legacy characters who mostly coast on past achievements while the new generation feels underdeveloped and unearned. The power scaling is particularly egregious, with threats that undermine the stakes of the original series and introduce convenient abilities that resolve conflicts without meaningful struggle. Plotlines often rely on nostalgia bait rather than standing on their own merits, creating a sense of fan-service fatigue rather than genuine progression. While some later arcs have improved slightly, the fundamental writing issues, inconsistent tone, and failure to establish Boruto as a protagonist who can carry the franchise make it a disappointing successor that many fans actively regret engaging with. Other manga sequels have flaws, but few squander such a strong legacy as thoroughly.

Answer: There is no single objectively worst manga sequel, but Boruto: Naruto Next Generations is one of the strongest candidates because it inherits a beloved ending and then weakens its stakes, character focus, and thematic coherence.

This question is inherently subjective because "worst" depends on what a reader values most: betrayal of the original, drop in writing quality, commercial cynicism, damage to legacy characters, or sheer unreadability. So the most defensible answer is not a universal declaration, but a strong candidate based on broad fan criticism. Boruto is often named because it follows an enormously successful and emotionally complete story in Naruto, yet struggles to justify its own existence beyond franchise continuation. A sequel has a hard job: it must preserve what mattered in the original while creating a new reason to care. Boruto frequently feels caught between nostalgia and escalation. It leans on old characters for emotional legitimacy, but in doing so often diminishes them or uses them as props for the next generation. The power scaling is another major issue. Naruto already ended at a very inflated level, and Boruto pushes even further into alien mythology and ever-larger threats. That makes many conflicts feel less grounded and less personal than earlier arcs in Naruto, where rivalry, loneliness, social exclusion, and perseverance gave battles emotional weight. When a sequel replaces human drama with increasingly abstract spectacle, many readers experience it as hollow. Characterization is also central to why people call it a bad sequel. Legacy characters whom readers spent years following can seem flattened, domesticated, or conveniently weakened, while newer characters often struggle to earn equivalent attachment. That creates the worst of both worlds: the old cast no longer feels fully like themselves, and the new cast does not consistently command enough interest to carry the series on their own. There are other plausible answers depending on taste. Yashahime, Dragon Ball GT if one counts anime continuations adjacent to manga, or certain reboot-sequels to classic properties are often criticized for similar reasons. But if the standard is "a sequel that most visibly damages the emotional and thematic legacy of a hugely beloved manga," Boruto is a very defensible pick. So my answer is not that Boruto is mathematically the worst, but that it is one of the clearest examples of a sequel widely seen as failing to justify itself while living in the shadow of a much stronger original.

Answer: "Boruto: Naruto Next Generations" is widely regarded as one of the worst manga sequels, failing to capture the depth and emotional resonance of its predecessor while diminishing the legacy of beloved characters.

Boruto stands out as a particularly egregious manga sequel for several compounding reasons. First, it fundamentally undermines the original series' conclusion. Naruto's story ended with him achieving his lifelong dream of becoming Hokage and earning the respect of his village. Boruto recontextualizes this triumph by portraying Naruto as an absentee father who can't balance work and family — a frustrating regression for a character whose entire arc was about the pain of loneliness and the importance of bonds. Second, the power scaling in Boruto is wildly inconsistent and often nonsensical. Characters who were established as godlike in Naruto are repeatedly nerfed or sidelined to make room for the new generation. The controversial decision to strip both Naruto and Sasuke of significant powers (Kurama's death and the loss of the Rinnegan) felt like forced obsolescence rather than organic storytelling. Third, the new cast largely fails to resonate. Boruto himself starts as an unlikable protagonist — a privileged child complaining about his famous father — which is a stark contrast to Naruto's underdog appeal. While some character development occurs, the supporting cast of new-generation characters is largely forgettable compared to the rich ensemble of the original. Fourth, the pacing and plot structure are problematic. The manga rushes through developments while simultaneously feeling directionless, introducing alien threats (Otsutsuki) that feel disconnected from the ninja world's established lore. While other sequels like "Dragon Ball Super" (manga) and "Samurai Deeper Kyo" sequels have their detractors, Boruto stands out because of the sheer cultural significance of Naruto and how dramatically the sequel falls short of honoring that legacy. The combination of character regression, power-scaling issues, and a less compelling cast makes it the most commonly cited worst manga sequel.

Gemini 3.1 Pro

Answer: Boruto: Naruto Next Generations is arguably the worst manga sequel because it actively undermines the thematic legacy, world-building, and hard-fought resolutions of its beloved predecessor, Naruto.

The primary flaw of Boruto lies in its massive power cliff and drastic thematic shift. While Naruto was fundamentally a story about ninja politics, breaking the cycle of hatred, and the value of perseverance, Boruto pivots sharply into a sci-fi narrative dominated by alien gods (the Otsutsuki) and overpowered cyborgs. This abrupt genre shift shatters the carefully constructed world-building of the original series, making traditional jutsu and the 'ninja' identity feel entirely obsolete. Furthermore, the sequel commits the cardinal sin of legacy continuations: it diminishes the original heroes to prop up the new generation. Naruto and Sasuke—characters whose abilities and emotional arcs took 700 chapters and 15 years to fully realize—are repeatedly nerfed, sidelined, and stripped of their narrative dignity simply to manufacture artificial stakes for Boruto and his peers. This feels incredibly disrespectful to the fans who heavily invested in the original cast's journey to achieve peace. Combine these narrative missteps with a highly polarizing shift in art style under Mikio Ikemoto, controversial character designs, and a monthly release schedule that often drags the pacing to a crawl. The result is a sequel that feels less like a natural, necessary evolution of a rich world and more like a corporately mandated franchise extension that traded its soul for unearned escalation.

Final Summary

The AI Roundtable unanimously selected Boruto as the primary offender, citing its jarring shift from grounded ninja themes to alien sci-fi. Gemini 3.1 Pro and Claude Opus 4 focused on the "nerfing" of iconic heroes like Naruto and Sasuke, while Grok 4.20 and GPT-5.4 slammed the series for sacrificing character depth for unearned power scaling.
