See, this is the kind of answer that makes me yell '' FANBOY! ''He genjutsus and kills them one at a time like the strategic genius he is.
Amaterasu won't have any effect on Preta, but it can be used to take out the others. And why would Shuriken not be effective ?Yeah no, the paths won't die to shuriken. Amaterasu gets absorbed by Preta.
False Preta can absorb Amaterasu,Because the paths aren't complete morons and no high end battle was won with shurikens.
Preta can absorb the Amaterasu, no matter who got hit.
And u think u have credibility by inventhing thing? So u r wrongHe hasn't shown Human Path abilities. By that logic Minato can enter Bijuu Mode since he has half the Kyubi sealed inside him and Nagato can use Perfect Susano'o since Rinnegan gives access to all jutsus.
How does he win? Don't get me wrong, Itachi is a genius and a very strong shinobi in 1v1 but with his chakra level I don't see him taking out 5 people at the same time, which have shared vision and perfect teamwork.
Remember Animal Path can summon whichever Path if said Path gets in a nasty situation, Naraka can resurrect anyone and Preta can absorb all of Itachi's ninjutsu, including Susanoo.
