Naruto Anime Quietly Nerfed the 4th Great Ninja War’s Deadliest Jutsu — a Change That Doesn’t Exist in Kishimoto’s Manga

Anime-only changes in Naruto are nothing new, but there is one tweak that still sticks out to me: Studio Pierrot quietly nerfed Kabuto's Reanimation Jutsu during the Fourth Shinobi World War. It is a small scene with big consequences, and it runs against how the technique is supposed to work.

What the anime changed

In the show, there is a nighttime sequence where Kabuto simply withdraws his Edo Tensei soldiers from the battlefield. Picture him just taking pieces off the board and calling it a night. That is not how Edo Tensei is meant to function.

The whole point of Reanimation is that those bodies do not tire and have absurd stamina reserves. Pulling them back does not help Kabuto. It helps the Allied Shinobi Forces catch their breath. Dramatically, it plays like the anime handing the heroes an unearned breather.

Why that clashes with the manga

Masashi Kishimoto's manga does not do this. There is no mass recall at night. In print, the relentless pressure from the undead army is the point: the Allied side is supposed to be buried under an advantage they cannot outlast. By dialing that back, the anime changes the balance of the war and undercuts the very purpose of Edo Tensei.

Edo Tensei was the war's engine

Kabuto is a co-instigator of the Fourth Shinobi World War alongside Obito. Kabuto supplies the muscle by resurrecting a roster of past heavy hitters with Edo Tensei and keeps them under his control, while Obito issues the big-picture orders from the shadows.

Kabuto's picks are the stuff of nightmares for the Allied Shinobi Forces: the Seven Ninja Swordsmen of the Mist, and eventually Madara Uchiha himself, among others. Every reanimated fighter is a major problem, and that constant pressure rattles the Allied ranks.

And it is not a one-sided tool, either. Late in the war, the technique also brings back the four Hokage of the past — Hashirama, Tobirama, Hiruzen, and Minato — who then help the Allied forces. The war does not look like the war without reanimation in the mix. That is how central Edo Tensei is to the story.

So was the nerf worth it?

On paper, Edo Tensei is a never-sleep, never-stop weapon. The anime's choice to have Kabuto pull the plug for the night makes the Allied side's situation less dire and, honestly, less true to the concept. Maybe it was meant as pacing, maybe as a breather for the audience, but it definitely softens the edge Kishimoto gave the war.
