Toei Has Continued To Receive Criticism, With Many Fans Accusing Them Of Using AI

Toei Animation is once again under fire from fans, as online criticism continues to grow over allegations that the studio has been quietly using AI in recent One Piece episodes. What began as a handful of skeptical posts has turned into a full-blown discourse across X (formerly Twitter), Reddit, and anime forums, with viewers sharing screenshots and clips they claim look “AI-touched,” “off-model,” or “uncannily stiff” compared to Toei’s usual work.

For many, the anger isn’t just about technology — it’s about timing. These accusations are surfacing right as the anime is adapting one of the most anticipated storylines in One Piece history: the God Valley Incident. Fans who have waited years to see this legendary event animated feel that any hint of AI involvement risks cheapening what should be a once-in-a-generation milestone for the series.

### The God Valley Arc Has Taken Over the Fandom

The God Valley Incident has become one of the most captivating storylines in One Piece history, and many fans aren’t ready for it to end. Eiichiro Oda’s exploration of this long-mysterious event has brought together legendary figures like Rocks D. Xebec, Gol D. Roger, Monkey D. Garp, and even the enigmatic Imu — creating a flashback that feels more like a grand historical epic than a side story.

In the manga, the arc dives deep into the power struggles that shaped the modern world of One Piece, revealing long-hidden secrets about the Celestial Dragons and the early days of piracy. For many, it’s a rare glimpse into the “true history” of the world, something fans have been waiting for since the manga’s earliest chapters. That’s exactly why the anime adaptation is under such intense scrutiny: viewers want the animation to match the scale, drama, and emotion of the story itself.

### AI Accusations During a Crucial Moment

As new episodes drop, some fans have begun pointing to specific crowd shots, background animations, and even certain character frames that they claim look “too smoothed out” or “generated.” Threads compiling alleged examples have gone viral, with users arguing that the linework, shading, and motion in certain scenes lack the nuance and personality of traditional key animation.

Critics say that using AI — even partially — during such a historic arc feels disrespectful to both the source material and the animators who built One Piece’s legacy. Others worry about what this could mean for the industry at large, fearing a future where studios quietly replace human effort with algorithms whenever production schedules get tight. While there is no official confirmation that AI is being used in a meaningful way, the perception alone has already damaged trust for many long-time viewers.

### Fans Don’t Want to Return to the Straw Hats Yet — But They Want Quality

Interestingly, the criticism of Toei is happening alongside a wave of overwhelming praise for the God Valley storyline itself. Many readers and viewers say they don’t want to go back to the Straw Hat Pirates just yet. Social media is full of fans expressing that this arc feels like the most thrilling part of One Piece in years — with its dark tone, intense storytelling, and lore-heavy revelations.

While Luffy and his crew are the heart of the series, the God Valley storyline offers something entirely different: a look at the legends and events that shaped everything we know. One fan summed it up on X: “If we return to the Straw Hats now, it’ll feel like waking up from a dream.” That dreamlike feeling is exactly why the visual presentation matters so much right now. For supporters, this arc deserves the absolute best Toei can deliver — not shortcuts, not experiments, and certainly not anything that *looks* like AI took over.

### A Debate About Art, Labor, and Legacy

Beyond the frame-by-frame breakdowns, there’s a deeper conversation happening about what animation should be. Some fans argue that limited, heavily assisted, or AI-touched animation undermines the soul of the medium and disrespects the animators whose work carried One Piece through its most iconic eras. Others are more cautious, suggesting that certain scenes may simply be the result of time crunches, outsourcing, or stylistic choices rather than AI tools.

At the same time, concerns about job security are surfacing. If studios normalize using AI to fill in backgrounds, in-between frames, or crowd shots, many fear it could eventually replace opportunities for younger artists to learn, train, and grow within the industry.

### A Testament to Oda’s Storytelling — and a Test for Toei

The enthusiasm surrounding the God Valley flashback underscores Eiichiro Oda’s enduring genius as a storyteller. After more than two decades, he continues to surprise fans by revealing layers of history that connect generations of pirates, marines, and rulers. The arc’s pacing, emotion, and scope have reminded readers of One Piece’s golden era — a blend of mystery, world-building, and drama that few series can match.

But that’s exactly why Toei’s alleged embrace of AI has become such a flashpoint. Even as fans celebrate Oda’s writing, some feel the animation isn’t always rising to meet the moment. For them, this isn’t just about one episode or one scene — it’s about whether the studio is honoring the legacy of a story that defined their childhoods and continues to shape modern anime.

Whether Toei eventually addresses the AI accusations directly or not, one thing is clear: the God Valley saga has already cemented itself as one of the most powerful and defining chapters in One Piece history. How it’s remembered visually, however, may depend on how the studio responds to a fandom that is more vocal, more attentive, and more protective of this series than ever before.
