1. Agreed.
2.Don't agree. It doesn't say that they have nine-tails level chakra, That would be insane, they are just tinted with its chakra, which means they some of its chakra, but they're far from the nine-tails' full chakra,
3.Itachi + Madara destroyed an entire uchiha clan and my guess is some of them were really strong if they were planning to attack Konoha. Madara also feared Itachi and Madara is stronger than the KinGin.
4. Ms is not much of a secret, agreed.
Also I didn't say that Itachi wins against anybody (people like minato, hashimara, tobirama and so on can beat itachi) but also be aware that Itachi has something very powerful on his possesion, which is the MS. He's most likely the strongest genjutsu user and combined with his intelligence it means that he can put anyone in the naruto universe at risk. Take minato for example. Minato has a high chance of defeating Itachi and I would say Minato would win if there was a vs. But also, you have to agree that if somehow Itachi manages to trap minato in a genjutsu, then it's all over. As unlikely as it may be, it is a possibility and people sometimes choose to disregard it.
Yes the KinGin are impressive, but, like everyone, they must have weaknesses. And as I said, Darui would have killed one of the bros it if wasn't for Edo Tensei, and it was simply because he was fast. So do you think Darui is that much faster than Itachi? You are a good debater and I agree with your points, but by now I think it's obvious that I can back my choices. I'm not making stuff up or declaring Itachi a winner "just cause".
2. let me reprase.. they have extreme amount of chakra that is tainted with 9tails... when Ao sensed them he shit bricks.. they have beast level chakra.. not exactly the same amount as the 9tails but they absorbed more chakra from the 9tails which is humanly unpossible.. its safe to assume they have ALOT of chakra and thus could have way more stamina than Itachi..
3. Itachi is a Uchiha prodigy and Madara was the best Uchiha known.. its kinda a given they'd be able to massacre the clan but Itachi knew by himself he could not massacre the clan. and its not Itachi and Madara vs KinGin its just Itachi.. also i would not say Madara wasnt afraid of Itachi but he was cautios of him. just like he's cautious of Kabuto.. Itachi knew alot about Madara. Kabuto evidently knows alot about Madara. they're threats to him.. doesnt neccessarily mean Madara is afraid of anybody..
i didnt say you said Itachi wins agaisnt everybody or say you make the "itachi at full power" arguement either.. just saying thats the #1 statement made most of the time when it comes to matches involving Itachi..
agreed Itachi is awesome with genjutsu but genjutsus are not unstoppable. theirs characters that are immune to genjutsus attack making them even immune to Itachis Tsukiyomi. Bee because of his Hachibi. Deidara trained his left eye. Sasuke even beat Itachi's genjutsu (whether Itachi used a weak gen or wateva Sasuke beat it.) not everyone can fall victim to gen..
i never said KinGin was unstopable, of course they have weaknesses but its still about match up.. Darui didnt show much speed in cutting an arm and cutting an arm isnt a fatal attack. we've seen many characters have arms cut off but still were dangerous and able to fight (Madara/Tobi [like 3 times], Jiraiya, Raikage. and besides like we said Naruto is about match ups. just because Darui proved he can cut an arm doesnt mean comparing Darui to Itachi would mean Itachi would do alot better. Darui is powerful, being Raikage's gaurd, general in the 4th war, and feeling confident to challenge the Kin Gin bros.. we dont know how Darui stacks up agaisnt Itachi but Daruis no push over..
also speed isnt everything.. and Itachi is fast but hes not the fastest.. in fact Itachi wasnt even a fighter he was more of a genjutsu speciallist. Sasuke was more of a fighter and ninjutsu specialist and i would even argue Sasuke was faster than Itachi even in Itachi full health..only clue we have to know Itachis full speed was when he couldnt dodge the shadow shuriken tossed by Sasuke. in his healthy state Itachi would have dodge it according to Zetsu and thats as fast as we know for sure Itachi could get.
other people faster than Itachi i would argue: Kakashi (hes gotten better since last time facing Itachi.), Raikage, Bee, Guy, Lee,.. but yea thats another arguement for another thread...
btw like i said your not those that use the "just cause" arguements.. your good debator too..
