1. Itachi can be defeated by lots of ninja
2. Amatarsu can be evaded
3. susanoo is very slow and not impenetrable
4. So6P owns anybody
5. Jinchiriki who are good will own him Tailed beasts bombs until he has to force quite the susanoo and you can dodge a huge ass sworn no problem
6. Itachi vs. Nagato ....Nagato wins (remember that kabuto was controlling nagato and doesn't even know how to use the rinnengan at all plus he got help from two of the strongest characters in the series where he would have been captured without their help
7.Tobi would own Itachi and so would Madara One of them trained him and helped with the massacre (look it up)
8.Itachi could be beat by alot of people stop trolling

1. Then why have those ninjas not defeated him? Clearly you are going on imaginative reasoning.
2. Thank you Captain Obvious! So is alot of ninjutsu in the Narutoverse! This helps how? It doesn't make you any less powerful if you've mastered it.
3. See above.
4. Where is he? Oh, once again you're going on "what if's".
5. Again this is purely in your imaginitive bubble that this would happen, but I'll bite; Itachi > Deidara but yet Deidara > Gaara (Jinchuuriki).
6. You're ignorant if you believe Nagato wasn't working at full power -- even Naruto mentioned this Nagato was stronger. Saying Kabuto was holding him back in any way is speculated ignorance. Also if I remember correctly, two of the strongest characters were about to get owned
until Itachi stepped in. Besides help destroy CB (which by the way Itachi figured out the weakness) what did they do? Nothing. Just like Oro, Nagato was caught off gaurd by Itachi's sealing sword.
7. Being trained by someone doesn't mean you can't defeat them. Do you even
watch Naruto?
8. See #1
9. Fanboys defend without reason. I have debuted all your imaginative references with reasoning. No fanboys here..
