One on One you say??? Itachi himself said that he couldn't beat him WITH Kisame's help. Did you just start reading the manga?? Blaze Release isn't the author/writer/creator so HELL YEAH I'd argue with him. And please don't start that Kishi was just boosting Jmans' prowess of him being a Sannin....if a story character tells another story character that he could only at BEST, HOPE to tied with him.....It's probably for a VERY DAMN GOOD REASON!!
3 Techniques....Chapters 147 & 148 clearly shows that he used only 2....get your facts straight before you start spewing your BS. You're a Uchiha Sac-Sucker just like all the other Fanboys who think the Uchiha's are some sort of diety....like they can't be fukkin beat.....Well then, why isn't an Uchiha a Legendary Sannin??? I'm an idiot....I post facts based on the manga...you're the ass-clown that's just spewin off at the mouth like the idiot just to say something without cause.....who's looking the fool now??
..........dude.... just STFU. You're sitting there trying to cover up and justify what his intention MAY have been, BUT the CREATOR is showing you otherwise. DON'T MISINTURPRET what is actually happening just to try to prove yourself right....Don't fight against the creator because you're gonna lose. In doing so, you're just lost ALL credability to post here....you are a Trolling on the manga to befit what's actually there...Itachi would lose to Jman....he may kill Tsunade (guessing), but he definitely would kill Oro because Oro even said he was stronger than him.....Oro has been caught in one of Itachi's genjutsu.....but to take on all three at the same time....he loses.
