Power and strength aren't skill. Skill is in technique and execution; Itachi went toe to toe with KCM Naruto and casually chatted with him whilst doing it, pertaining to the fact that his abilities were second nature and didn't require focus.
Gai has beaten Kisame with taijutsu alone on every occasion they fought, so no, he's not that impressive.
This post is such bullshit lmao, 30% kisame beat base gai, gai had to use gates. And every other time gai used gates and every person gai has ever beated lost with gai using only taijutsu. Itachi went toe to toe with kcm Naruto. Well umm are you implying 100% kisame cant? If that's the case you're a bit, umm, retarded as they would say.
Kisame would neg itachi.
Kisame knows of tsukyomi and would not look at itachis eyes. Samehada can disrupt kisames chakra negating finger genjutsu.
Both kisame and Samehada have shown to absorb ninjutsu so amaterasu isn't a factor.
Kisame can use water dome to drown Susanno. And totsuka isn't touching kisame underwater.
5 feeding sharks made gai use 6 gates so 1000 would be just fine for itachi with his low low stamina.
Any other attack itachi uses is just absorbed which kisame would use to heal himself.
Inb4 you say itachis fireball hurt Samehada so samehada cant absorb amaterasu, well that's bs as well, what's he going to do? Just let it burn him? It might hurt but he can still absorb it. Or Kisame could as he's already proven to be able to absorb chakra and heal without samehada.
7 gates gai would also neg itachi.
