Can the Tailed Beasts' relative power levels be compared? A Tailed Beast's power seems to be greater the more tails it has. For example:


Power of 3-Tailed Beast = Power of 2-Tails + 1-Tails.
Power of 9-Tailed Beast = Power of 8-Tails + 7-Tails + ... + 1-Tails.


This is clear. But is it possible to compare the power level of the 1-Tails and 2-Tails with this equation? Does the power of the 2-Tailed Beast = the power of the 1-Tailed one? Or is it greater?

Badranious's answer in this thread.
Actually, it's never explicitly said that every Bijuu is stronger than all of the Bijuu with lesser tail number combined.

The practical power probably is determined by tail number (even though the Eight Tails told the Nine Tails that it isn't, much like 'friendship' is more valued than 'power').

It is stated that the Nine Tails is stronger than all of the rest combined, because Itachi said that if it were to be sealed anytime but last, the Gedo Mazo won't be able to withstand the imbalance, and will break apart.



There isn't a clear power distribution and balance, nothing is explicitly stated, so most of what you'll hear is speculation.

As for the specific question, I'd say that the Two Tails is "just stronger" than the One Tail.
