Nope. Also in the sense that the negation applied to Ninjutsu/chakra-based attacks that struck his body. The analysisor explanation of said analysis, I guess would be more appropriatewas what he said immediately after the Senjutsu Rasengan struck Obito's back:Yes, my bad.
Tobirama's analysis came after the Gudōdama got rid of the Amaterasu flames though so he didn't infer that, not really. If you're referring to the negation taking effect outside of the Gudōdama in the sense that Minato couldn't regrow his arm, then I'll agree with you.
"Even though Ninjutsu doesn't work... Senjutsu attacks do!!... The Senjutsu of the frog from Myōbokuzan... That he couldn't erase it was proof!"
Be it Onmyōton, or the fact that the Jūbi is a huge mass of natural energy(though I doubt this, as the Jubi itself could still be harmed by Naruto and Sasuke's prior, inferior combination attack), the body of it's Jinchūriki was also impervious to normal, charka-based attacks.
I'm afraid I'm not seeing holes, but Obito altering the Gudōdama to the semi-multi-disk-like shapes that he was using before the Jūbi's subjugation; shaking and pushing the sticky substance off:Whatever it did, it caused holes to form in Obito's shield. Check it out in chapter 642.
The point made by Tobirama wasn't that the Mizuame Teppō was eradicating the Gudōdama, but that the Gudōdama were not eradicating the Mizuame Teppō.
Just as he said that Naruto inherited Rikudō's Yang power, but we know he had Rikudō Senjutsu on top of that. Sasuke spoke in terms of what was necessary to use the Fūinjutsu Hagoromo prepared for them.Sasuke said he inherited Hagoromo's Yin power, so whatever that Chidori was, it was probably the same as Madara's Yin based lightning attack and thus capable of damaging him.
Moreover, it has yet to be established that Hagoromo's power of Inton or Yōton are capable of damaging those like himJūbi Jinchūriki. We have only been told that Senjutsu-based chakra attacks are able to do so.
That's fine, as long as my point got across. I'm not denying that Ninjutsu negation was tied to the Gudōdama, but that it was also present on the Jūbi Jinchūriki's body; it was the fact that Gamakichi's Mizuame Teppō couldn't be "erased" that lead them to suspect that Senjutsu would be capable of successfully inflicting damage upon Obito's body as well.I think that the manga is pretty clear on negation being tied to Gudōdama but I also believe this argument has run its course as we're just regurgitating points we made earlier at this point.
