A topic that gets sometimes thrown around, that causes confusion, but also an important question when trying to determine the durability of TSBs, since they were used to guard the Juubi Jin against four Juubidama:
So, did the TSBs actually tank the Juubidamas or did they simply nullify them? I'm gonna try answering this.
Let's first start with the basics, namely a Juubi jinchuriki's and the TSB's inability to nullify Senjutsu-based attacks:
As we can plainly see above, Gamakichi's attack (Senjutsu-based) wasn't nullified. In fact, we have confirmation that when TSBs don't erase attacks, they simply tank them (duh):
Notice how the TSB cracked, and Naruto even commented on the thing being solid, hard, which is proof there was resistance.
We have confirmation from Kurama that the Juubi is simply a mass of natural energy:
As you may know, Senjutsu is natural energy+chakra.
In fact, we were also given a direct comparison between Gamakichi's Senjutsu attack and the Juubi:
This is proof that the Juubi's attacks are all Senjutsu-based, and thus can't be nullified by TSBs.
We also know that Juubi jinchurikis use Senjutsu-based attacks aswell, which confirms they use natural energy:
In conclusion, based on everything above, the Juubi's Juubidamas are Senjutsu-based, and thus the TSBs can't nullify them. So in the Obito scan I gave, the TSBs tanked the attack, not nullify. Therefore, the TSBs when formed as a shield, have the power to tank the equivalent of four concentrated Juubidama explosions.
Let me know what you think.
