If you believe jinton beats yata, then this goes to team Kage.
It probably doesn't but Tsunade's fist should.
:| keep is cute,Of course, how silly of me to forget.
Tsunade could probably destroy planets with her fist, she can just knock Itachi in to space if nothing else.
sarcasm game too strong
:| keep is cute,
He fist > Susanoo.
Itachi Susanoo < MAdara's
Itachi one shots them both with amaterasu.
Itachi wins. He's more skilled than Tsunade close-combat and his Jutsus would obliterate her, although he'd save up the problem of having to fight her, for he'd just put her in a Genjutsu since the beginning.
Onoki would be taken out with Yasaka Magatama since he's a flying user - a power which evidently rivals Rasenshuriken (when it comes to damage and raw power, not the level of destruction).
Supposing that was not enough to take him out or wouldn't even touch him, Itachi would outlast Onoki, an old man with back problems, with his infinite stamina.
So Edo Itachi wins mid/high diff.
Itachi wins this mid diff
--Both tsunade and onoki are not evading amaterasu, the jutsus continous burning effect renders byakugou useless, and tsunade gets turned into a flaming fire ball consuming all the oxygen around her and making her unable to fight
--Jinton gets intercepted by either YM or amaterasu, and onoki resorting to use any of his dotons would lead him into getting cleaved in half by susanoo
I have good reason to believe ama dosen't burn /consume oxygen.tsunade would shrug off ama like ay did.
it dosen't ignite from wind though. Or should I say it burns through wind chakra the same way it would burn through fire chakra, or burn through ice. As far as scans go the burn rate is constant despite the burning material in question. Hence why I don't believe it would burn oxygen unless the target is oxygen, in the same vain as how it burned ice and only ice despite noodles being in Los, or how it burned through sasuke's katon and grew bigger.its just like any other fire, only stronger
no reason to believe why it wont consume oxygen, when it ignites from wind just like any other flame
bold is an inconclusive assumption.not to mention that itachi would aim it right at tsunades face, she isnt amputating that off unless she wants to die a quicker death
