We Kaguya is the Juubi itself, and all Bijuu regenerate if they die or are destroyed, so Kaguya probably would.
Madara would not, however.
As the title says,for example,if they are hit with a senjutsu enhanced jinton,will they regenerate from nothing?
the perfect examples are characters like Buu in which case a wide ranged powerful attack will completely eradicate them. In madz and kaguya's case, big range attacks like juubidama or full size gudoudama will vaporize them beyond repair.
Can't really say anything with resoluteness about the regeneration factor, because that's a tricky question. No one can answer it straight. But something to note is that even a Senjutsu enhanced Jinton can be absorbed by Preta Path and Kaguya's absorption, so countering it isn't a problem. But in a situation where they get disintegrated by Jinton... it's a wild guess, but I think Kaguya will completely regenerate even then because she is the Juubi and it will undoubtedly form again, Madara is still a maybe, but he could be able to because he has the Juubi.
Exactly, Madara and kaguya cannot regenerate, 'cause they are not cell or buu. Even they cannot regenerate every time
Well, thats not true. buu or cell cannot regenerate from a strong wide range atack. In other words bijuu rasenshuriken or bijuu dama may destroy buu and cellokay dbz fanboy,so you trying to say only dbz characters can regenerate,try again
i just used the scenario not saying they can absorb it
I answered that as well however I could. This was just an additional point.
