And why he would?Because he is the hokage,the good guy that saves the village?Sorry man,but Itachi killed his own clan,sacrificed everything in order to protect the village from civil war.He made himself an wanted criminal,disposed from his own village and everyone is thinking he is the culprit.But guess what?The third couldn't stop the elders and so that shit happened.Another point I have is this. From Kishi's mind, if he wrote a Itachi vs Minato story. Do you really doubt Minato wouldn't come out the victor?
That's pure BS.As far as I know the Susanoo is far the best jutsu Itachi developed.May say Susanoo was his ultimate .(just like death-god sealing jutsu).Itachi hasn't even scratched the surface of developing his own jutsu much less a jutsu on the level of FTG,
Another BS.The First defeated healthy Madara with EMS,but Minato couldn't beat a regular sharingan Tobi.And Minato is certainly stronger than the First!
I think rasengan is an A-class jutsu.Not badass jutsu.MS jutsus are all S rank classed and badass.
