A lot of people in the thread I was debating in had confusion on both sides over the subject. He hit Naruto, and Naruto tanked it.
Actually he can. It is the same concept as Kaguya's S/T. He was able to dodge it efficiently, but when Kaguya sent one attack from behind, she simulatenously sent an attack from in-front. Ultimately killing the Naruto clone.
Same concept here. Sasuke used a fireball jutsu to distract Naruto, in turn after he blocked it, not a second later Sasuke teleported behind him to strike him with Chidori. Even with that limited time for the distraction, he was able to at least perform some type of dodge or block. Meaning that Naruto can react to the attack incoming, but obviously he cannot react to the teleportation.
Nope. Chidori was shown to be more effective than Chidori Katana when Sasuke tried to slash Ay and failed, but ended up piercing him. So he wouldn't have cut through Naruto.
That's mainly because both Naruto and Juubi Jins in general have different forms of tanking prowess. Kaguya and JJ Madara can actually get hurt, but regenerate over the period of time. Naruto, much like in his KCM/BM/RSM forms, when he gets damaged, nothing really affects his body. Detailing that you would need a much stronger attack to eradicate him all together. A chidori, or a chidori variant is not providing enough strength to cut a RSM Naruto down. If you think so, I would advise to read back to the War Arc and look at the earliest of KCM tanking feats Lol
This had already happened before when Naruto was fighting Kaguya.
He reacted to her Amenominaka easily, but when she decided to distract him with more than one technique, it became the downfall of him completely. The same is applied here. If Sasuke's attack incoming after Amenotejikara was fast enough to strike Naruto directly, Kishimoto would not have had drawn the distraction in the first place. The fact that Sasuke needed to use the Great Fireball jutsu setup to then play a part in the Blitz itself, put's Naruto's reaction time at an even better advantage. If it happened like this: Amenotejikara > Naruto senses > Chidori creation > Naruto dodges similar to how Madara did with FTG > Naruto counters, stalemating the attack or continues to pressure Sasuke.
Naruto did not use the TSB to tank against the technique. Sasuke hit him.
