I've seen on the internet before that Kishimoto has said himself Itachi would beat Madara in a fight. Obivously if this is true, then none. If it isn't true, however, then for me I'd probably still say none. Raikage and Tsuchikage would have the best chance imo, but for me, Itachi could end up beating all of them,
@bold, that was years ago, back when Tobi was known as "Madara". Meaning that Kishimoto has stated Itachi can beat MS Obito in a fight.
ot: Honestly, none of them would beat him. But the closest that would come to beating him would probably be Gaara, considering that he can rely on his long-distance techs the most. Though, in the end if Itachi were going on a 1v1 with any of them, they would lose.
-A fell for Madara's genjutsu. I honestly don't see it being any different for Itachi, especially considering that his arsenal revolves around genjutsu and Maddy was just using it for kicks.
-Tsunade, Mei, or Onoki can get hurt by genjutsu, amaterasu, susanno techs like Yasaka Magatama, etc. Itachi also has a faster base speed than all of these 3.
-Gaara shouldn't look at Itachi's eyes, finger, or crow summons'. Too bad he has no idea that Itachi can cast non-ocular genjutsu, neither do the other kage.
