Not much earlier, it was during or slightly prior that fight during Edo Jinchuriki, first sings Kurama shown at time Madara used Advent of a World of Flowering Trees, and at this time already rest of battle fields were dominated by Naruto and it was moments before jinchuriki fight.

Yes, there was some chakra exchange thing that I missed. I apologize.

But still, he did use Nine Tails' Chakra not his own chakra as you said. I re-read that chapter once again and Gyuki said to him that as he used NT chakra, his own chakra would get sucked in, but he didn't specify the amount of chakra Kurama sucked in exchange for the amount of chakra he got from Kurama. 'Cause if Kurama would take in the same amount of chakra that Naruto would take from him, then considering Naruto's chakra is 4 times larger than Kakashi's while Kurama's chakra is 100folds more, Naruto would have died pretty early.

I butchered the math but I hope my point got across to you.

Also, I re-read Chapter 567 too, and Gyuki again deduced that Kurama had stopped absorbing Naruto's chakra at some point. He didn't specify when. However, it is heavily hinted by Kurama's flashback that he stopped absorbing his chakra after Naruto told him that he'd come for his hate one day, more specifically in Chapter 539 AFTER Naruto and Killer Bee had yet to fight edo Itachi and Nagato. So yeah, the chakra absorption had stopped long ago. And Bee himself said that Naruto would have died if he made so much clones using the same amount of chakra as his.

Seriously dude, if you want to see Naruto's potential without Kurama's chakra, look no further than his fight with Pain. He had no assistance from Nine-Tails there yet he couldn't make more than one or two clones asides from the ones he left in Myoboku to collect Natural energy, before ruining their balance. Why didn't he have that problem during the Fourth War after taking Kurama's chakra in? He could make half a dozen/a dozen clones with the capabilities to take down Kage-level edos, and he could use SM and Wind Release without breaking their balance. He was nowhere near Hashirama's chakra feats.

You do realise that a kunai to Hashirama's head should be more than enough to end the fight?
When Hashirama and Naruto enter SM they use a fraction of their chakra to mix with nature energy not all of it where as Jiraiya's and Kabuto SM allows them to absorb NE and mix NE continuously. It's logically evident that both will have SM much longer than other sage mode user.
Since when did breaking Edo Tensei implied that he could break Genjutsu? Especially when Orochimaru didn't use the controlling Tags as well as he was using Hashirama's cells to bind them. So than according to you those who defied Edo tensei without the apparent advantages Hashirama had should be even stronger at breaking genjutsu? That doesn't even make sense.

@Namikazenaruto9

Not really. We know that the only damage that Hashirama's healing can't repair is lost limbs. There is no proof that he won't be able to shrug off a kunai to the brain. And when has a kunai defeated an important character anyway?

And I get what you're saying regarding Jiraiya and Kabuto, but in terms of the battle's length Hashirama can maintain Sage Mode just as long. We've already seen him activate it almost seamlessly when against Madara which implies he can accumulate NE pretty fast. And in Jiraiya's case, his Sage Mode fails the minute Fukasaku and Shima are knocked off his shoulders.

Edo Tensei exerts control over the brain. Genjutsu, no matter how it's taken, assaults the brain. Obviously, if you can break edo tensei, no matter how, then you can also break genjutsu. It makes sense really - how did Koto break Itachi out of Kabuto's control? And sure, while Orochimaru used Senju cells to control Hashirama, he was still surprised that he broke through it which means that was not supposed to happen. Plus, Tobirama's a Senju and if Naruto genetics have any semblance to real life, he should have broken through it too.

I don't think anyone who's broken Edo Tensei is stronger than Hashirama, no. Mainly because we knew as soon as Sasori was revived that Kabuto's Edo Tensei was fairly unreliable.

No amount of healing guarantees safety against Brain or Spinal injury. think about it. Plus we don't know how Hashi's healing actually works. I mean would it still heal if brain is damaged or so on?
You are making contradictory statement wrt Edo tensei.
You claim that Hashirama should be able to resist genjutsu because he could resist Edo tensei. Yet when other characters could resist it you said that they can't break genjutsu. I mean that doesn't make sense, it's clear their is common ground i.e. breaking Edo Tensei. the Event is escaping-breaking out of that jutsu. Now Hashirama had clear advantage over others(he was brought back in his clone body, his cells were used to control the jutsu, their is no controlling tag hindering him) and he breaks the jutsu.
Others break out of the jutsu despite not having ounce of that advantage, as far as I can see you are having a bias because Hashirama is strong. the feat is not noteworthy and it doesn't imply hashirama can break genjutsu simply because if that was the case Naruto would have broken through any genjutsu with sheer will power.
I am not sure but Hashirama can't fight with SM throughout the fight, Jiraiya and Kabuto can also might I add one of them still remaining implies that Jiraiya still in SM. And their sum of chakra could be comparable to Hashirama's chakra.

Hahahahaha!!!!! Ohhhh the irony. I'm sorry, but I just couldn't pass this up. You do bring up interesting points, though

@UltimaDude Eh, you do have a point. But I don't think a simple stab with that would have killed Hashirama. He was probably thinking of committing sudoku or something of the like.

@Namikazenaruto9 I am not favoring anyone. Most of my favorite characters are in the opposing team. I'm just trying to play this one fair. And I'm not making contradictory claims - but both of these Edo Tensei versions were activated differently. Kabuto siphoned chakra from Orochimaru's curse marks to exert control over the summoned shinobi, while Orochimaru used Senju cells. Another difference is that Kabuto summoned more than a dozen shinobi while Orochimaru summoned Four for a short period of time, which he then released from his control. Heck, one of them broke through his control before that, so that makes it three. So, I guess it's a matter of which is stronger - Senju chakra or a type of chakra harvested from Sage Transformation. Taking into account which one of those two was coveted more in the series, I'm gonna have to go with 'Senju's cells.

But okay, even if we assume that Jiraiya and Kabuto's sum of chakra is comparable to Hashirama's, they still don't have access to his enhanced version of SM or his multitude of devastating techniques. Heck, Jiraiya's SM was shown to lack the extraordinary sensory perception usually granted by this mode AND the enhanced strength. All he could really do was enhance his existing techniques.

Also, pretty sure Tsunade, with her slightly weaker replication of Hashi's healing managed to shrug off spinal injury when Madara's bigass sword went through her. She even managed to stay conscious for a while after she was cut in half and her healing failed. And if Hashirama's regeneration can constantly regenerate dying cells without any drawbacks, that must apply for brain cells too.

You are too biased to conclude anything. Naruto won't die because again we don't know how much he does waste on justu castion - this same problem with Hashirama you are concluded he has bigger than Naruto chakra because of size justu he casts - which is utterly fallacious because we don't know thing about their chakra usage. So spare everyone's time and do not bother with "maths" at all.

I won't even address your bs about chapter 539 - it shows how sore orator you are.

And lastly Naruto everywhere near Hashirama feats because he is same frikin reincarnation of Ashura with same bloodline and with Kurama chakra he by far tops Hashirama feats. For the future learn how to read manga stop making weak excuses when you are pointed to facts it is not matter of belief.

Oh? So, why didn't Sasuke have the same large levels of chakra as Madara then? If they are both Indra's incarnates then by that logic they all should have the same chakra levels, right?

And you telling me to read manga better when you started this argument because you misunderstood Hashirama's manga statement is quite rich. I'd also advise you to stop with the brute rhetoric. I admitted to making a mistakes in judgement in the duration of this debate and I apologized for it. You can take your condescending attitude elsewhere.

Hashirama takes this with high difficulty.

What is Madara "large levels" where did you find them? Marada's Sasuke's and Uchiha's chakra in general was called strong, evil, prominent, malicious - it was never was called large and never was, existence of Sunanoo itself proves that one does not need big reserves to have big jutsu.

Are arguing in pure statement which is literal Hashirama stated for one to share chakra with entire SA(several dozens of thousand people) one must have comparable to his chakra levels. Kurama explained that Naruto gave everyone his chakra(already fulfilling Hashirama's logical requirement) which worked as mediator.

I do not use brute rhetoric - and I advise you stop trying to act as mod here, you were give undeniable manga facts which you are still denying and that makes you biased. If you unable to follow normal conversation without moving goal posts then just stop.

Hashirama loses.
