Isobu

To be perfectly honest.

Among the nine Tailed Beasts.

The only ones that could truly be called peerless in strength.

Are Nine-Tails—Kurama and Eight-Tails—Gyuki.

The remaining Tailed Beasts are simply not on the same level as these two.

Especially Nine-Tails!

Heaven knows if the Sage of Six Paths—Otsutsuki Hagoromo—had taken the wrong medicine back then.

I seriously suspect he divided half of the Ten-Tails' chakra into Nine-Tails. This resulted in the nine Tailed Beasts having highly unbalanced combat values. At best, only Eight-Tails Gyuki could barely contend with Nine-Tails; the remaining seven Tailed Beasts are truly the definition of "little brothers" compared to Nine-Tails. Even so, a Tailed Beast is still a Tailed Beast.

Even weak existences like One-Tail or Isobu.

Are not entities that an average Ninja can confront.

If they were to truly unleash their full firepower.

Only Ninjas with strength infinitely approaching the Kage level would be qualified to face them head-on.

Take Might Guy for example.

It would take Might Guy opening the Five Gates, or perhaps the Six Gates, to truly handle a fully manifested Tailed Beast.

Of course, this is not a very accurate statement.

Because such a matchup never appeared in the original story.

The most important point is.

The Eight Inner Gates are a bit too broken!

Furthermore, the gap between the Eighth Gate and the preceding seven is as vast as heaven and earth.

If opening the first seven gates only fluctuates one's strength between a super Jonin and a top-tier Kage, the Eighth Gate represents a sudden leap to the level of Madara in his Six Paths form.

You can imagine just how massive that gap is.

Therefore, don't be fooled by the fact that there is only one gate difference between the seventh and eighth; that is the difference
