Certainly. Sasuke can see through his clones, now that he has EMS, and Madara doesn't appear to have used Amaterasu as well. It may possibly be true that he did not face Amaterasu, otherwise, it seems kind of odd that he survived it at such a young age against it. No matter how strong he was, this is just ridiculous.
Perhaps he did so when he was older, but we do not know that for sure. Mokuton growth does appear to be quite fast though, as shown by Danzo when he made an entire tree sprout before the arrow hit him. Now if Danzo can manage it; I can only imagine how fast Hashirama's Mokuton techs must be. But are they faster than an eye's perception?
If he senses it - which again seems far-fetched - then he will stop it in its tracks for sure. Again, this is theorizing but I believe he used to do so because of Tobirama's aid, or maybe he could sense it himself. Once sensed, he would definitely manage to block it with Mokuton. But that's only wasting chakra, as Amaterasu's stray flames burned an entire forest down. Just imagined what a focused Amaterasu would do.
His Mokuton techniques would definitely be rendered useless against it. Unlike Madara's slashes that crush or cut, Amaterasu is fire that burns and eats through everything and continues to do so until stopped by the user himself. Sasuke would be the worst possible match for him, including Obito. As both of them have great counters for his Mokuton techs.
The databook also states that Ama burns hotter than the sun
Yet we've seen no sun feats from Ama
Your argument is invalid
You really are a garden variety and a rather unimpressive troll, aren't you? I remember you clinging for your dear life to that 'Petra Path' absorbing every damn ninjutsu, which would include seals, Kage-Bushin, Body-Flicker etc and god knows what else. People - including me - endeavoured to reason with you, how the words of Databook are not law and are largely hyperbolic in nature to emphasize on a point.
But NOW it's all convenient, because Sasuke is involved and back then it wasn't because you believed so? No one should take you seriously after this. You have got to be one of the worst posters here. And I am flabbergasted that despite reporting Sasuke's trolls, none are ever banned by the moderators. This shows this administrations' lopsided attitude. Deplorable.
