Talking with the eight tales plus one of the land of lightning guys telling him about the scar is what gave naruto the idea of using raikage's attacks against him. Without those, naruto wouldn't have beaten him. He hit the raikage with a rasenshuriken and literally it did nothing to the raikage. Even naruto stated it. This is especially impressive considering that wind naturally counters lightning and yet rasenshuriken did nothing to the raikage but to remove his lightning armor.

Okay now on to itachi. Itachi using amaterasu wouldn't do anything but to maybe burn the battlefield since the fourth raikage was able to easily dodge sasuke's amaterasu and proceeded to nearly blitz sasuke. The third raikage is stated to be faster and stronger than the fourth so I don't see amaterasu hitting him. Itachi's intelligence and ability to find a weakness to every jutsu is dangerous for most opponents, but not for the third raikage considering his most powerful technique literally has not weakness except to pull out a jutsu powerful enough to break through his perfect shield; something that itachi doesn't have since he hasn't really shown any strong wind techniques. Totsuka blade is iffy at best since it's a big sword that can be easily dodged given you have the speed to do so. To further upon this, itachi had to capitalize on nagato being momentarily dazed by chibaku tensei's destruction to be able to hit him with the blade.

The yata mirror is the most OP thing in the anime and manga but it is also not omnidirectional. Itachi's susanoo also hinders his movements making him a slow and big target. If he can turn the mirror fast enough, then he can hold off the raikage but given the raikage's speed, he could just go around the back of itachi's susanoo and hit him from there with his strongest spear technique which can definitely pierce the susanoo.

I just don't see itachi having anything other than the totsuka blade to combat the raikage and that is considering he can even hit the raikage.

edit: also forgot to point out that tsukuyomi and genjutsu would only work if the opponent directly looks at itachi's eyes, which the raikage would most certainly not do. And with his speed, I doubt itachi would be able to force the raikage to look at him. To further upon this, madara had to stop the fourth raikage with his susanoo so he could put him under genjutsu. I don't see itachi's susanoo doing that to a faster and stronger third raikage.

Look I'm not taking away anything from naruto but the info literally given to him is not an inherent part of himself, it's an outside factor. If he had fought the raikage without gyuki there to tell him the story of how he fought the raikage or that lightning ninja to tell him about the scar, then he would have at best been in a stalemate with the raikage where he would keep launching rasenshurikens until he either runs out of chakra or is forced to retreat. It would have been another thing if Naruto were able to put together the pieces by himself (which would be impossible) which is why the lightning ninja and gyuki had to be there to tell him about it.

Itachi is by no means the fastest character in the series. Arguably, shisui is faster than him and so is minato. Now, true that Ay does have to get close to him to attack but it doesn't really matter if he can close the gap between him and itachi in literally less than a second. During the fight between the fourth raikage and sasuke, sasuke was struggling to keep track of the raikage even with his eternal mangekyou sharingan; something that itachi did not have. If sasuke had trouble with the fourth raikage, then I don't see itachi faring any better against the stronger third raikage. Also to mention is that itachi has never shown the ability to control amaterasu the way sasuke does to cover his susanoo like a flame armor.

And as I've already said earlier, the tsukuyomi is a non-factor given itachi wouldn't really be able to force raikage to look him in the eyes for him to use it. The raikage's speed is faster than the sharingan can see.

What, no. But before I explain, let me point out that sasuke DID NOT have eternal mangekyou at the five kage summit that was a mistake. But that said, sasuke obtained a substantial powerup that rivaled itachi's during the summit arc. I'm not saying he could win against itachi, but the only thing stopping sasuke from surpassing him is the totsuka blade and yata mirror. I bring up the raikage vs sasuke part because it's a good way to scale off itachi and the third raikage. Sasuke at that point was comparable to itachi, with itachi being slightly more powerful. The third is more powerful than the fourth and if sasuke is comparable to itachi, then it's safe to say that the third is a bit too much for itachi to handle. Also, the condition to use izanami is to replicate the sensation you and your opponent feel during a clash of attacks (like when itachi blocked kabuto's weird claw hands with his sword) Now, if you can concretely say that itachi can do that block with the raikage's full powered thrust then I concede that izanami would be a closing factor.

Where did you get that itachi is far far stronger than naruto at kcm? Naruto was holding back against him during their fight to tell him about sasuke. If he had gone full speed, itachi would have gotten overwhelmed. And the fourth and third use practically the same lightning armor jutsu, just that the third is far more superior to the fourth. This was stated.

I use it to compare because itachi and sasuke have the same level of visual prowess (both using mangekyou) and the specific point I was bringing up is the speed blitz that sasuke had to endure before he caught the raikage in his blaze release susanoo armor. I specifically pointed out that sasuke couldn't keep track of the fourth's speed. Ergo, the third who is even faster would be too much for itachi to keep track of. Now, if you're going to argue that itachi's visual prowess is greater than sasuke's then please name a scenario where that was stated or shown. Because as it was shown in the mange and anime, pretty much every sharingan provides the same boost in visual capabilities. It's just a matter of by how much it boosts the person's base.

edit: sasuke and itachi's style are not that far off. Itachi literally passed his powers on to sasuke. The only outlier is the totsuka and yata mirror which he kept for himself.

edit edit: and like I already mentioned as well, the rasenshuriken did nothing. It didn't damage the raikage. That's the point I'm trying to make here. If one of the strongest wind techniques coming from a KCM amped naruto didn't damage the raikage, I don't see itachi dishing out a technique that can damage the raikage either (since he has never shown a technqiue with the same level of destructive power as the rasenshuriken. Except maybe for yasaka magatama)

What are you talking about. Itachi didn't have the option to "hold back" in the fight because he was being controlled by kabuto. He didn't want to fight naruto but had no choice because kabuto wanted him to. When kabuto gave the order to attack, the best that itachi could do was to shout warnings at naruto about what he was going to use to attack next. And we're talking about speed here. I'm saying itachi has neither the capability nor ability to dodge a full speed assault from the third raikage.

And you're saying the only version of naruto that can beat itachi is six paths mode? Are you forgetting about kcm2 cloak naruto? kcm 1 is already on par if not superior to itachi going by feats alone. Naruto, when using the full speed of his kcm, was faster than the 3rd raikage but even he admits that it's pointless since his attacks can't damage the raikage.

my god, you just literaly rephrased what I just said. That. Is. My. Point. Itachi didn't want to win. He wanted naruto to win. And although you could argue he was holding back, it isn't really by much since he still has no control over his movements. If he did, he would have just stopped moving to let naruto hit him.

I am trying to say that the raikage can move around fast enough to get behind the susanoo and pierce it from thereeeeeeeee. The raikage would hit the mirror once and realize it's impenetrable and would just adjust his strategy to move behind itachi and strike.

Lol the original poster thought the raikage could just get behind itachi and pierce his susanoo and kill him. While Itachi is not doing anything. Even so, at best it could only crack the susanoo, or his finger going inside the susanoo a little bit, not enough to reach itachi.

TBH Kirin is a stronger jutsu than raikage's finger.

Edo tensei ninja are not weaker than when they were alive. When Madara came from the death he was stronger than when he was alive because Kabuto enhanced the jutsu and the body of Madara. When Tobirama came back, he said that this time Orochimaru brought him back with his full power unlike the time Hiruzen defeated both the first and the second Hokage alone. Also, Minato is not fast, he teleports. It's completely different. Minato's reaction time is not as fast as Ay or any fast ninja, his body doesn't move so fast either.

Well, depends what Minato you're talking about. In Kurama form he was faster obviously but the normal version relied too much on Kunais for "speed".

I will leave this here for the edo tensei debate.

Also, I insist there is a difference between being fast and being able to teleport. Ay moves faster than a kunai thrown by Minato.
