this is what i was going to say. if itachi could have. he would have.That depends on weather itachi was in his prime or not because if he could have i think he would have done it when he had the chance back in the akatski
Itachi doesn't have that jutsu, Only shisui...Tobi but if itachi would be allowed to use kotoamatsumaki then there is still chance for him to win.
ThisIf it's current Tobi then he takes it with low difficulty. If it's 3T Tobi then Itachi stands a decent chance, but I think Tobi would still win.
Pain also said "if Jiraya knew my secret, we couldn't have win". Do you believe this?sorry to say but its fact that tobi said "if itachi knew about me then Im finish" Image id itachi know tobi and figt one on one, itachi will win if he know tobi's secret. But for now itachi still don't know much about tobi then tobi win.
sike only edo madara becuz of skill and experience wit ems and itachi wen this itachi is smarter then thatIf it's current Tobi then he takes it with low difficulty. If it's 3T Tobi then Itachi stands a decent chance, but I think Tobi would still win.
