dude you're getting me all wrong.
the fact tat naruto could control a tailed beast is fine by me, but to assume that naruto is now and all power godlike ninja just doesnt sit in too well. he needed kyuubi's chakra to become like daddy?
Now assuming that the kyuubi IS the most powerful tailed beast, controlling it still does not make naruto THE most powerful ninja, right? if size is all that matters in this manga, the whats the purpose of skill? with these, so called 'power ups', all we're gonna see is naruto going from SS1 -> SS2 -> SS3....
im not gonna make comparisons with sasuke her coz its not worth a dime at all. That guy is plot armored for bigger things i guess.
so since kyuubi is uchihas and senjus toy, it makes kyuubi the most powerful tailed beast? It appears that there are clans which can be as fearsome as the senjus and uchihas...(uzumakis & the bee's clan for eg).
lets not get carried away with history,just becoz the senjus and uchihas has the most decorated, blood stained history.
It also appears that there are ninjas, who are supposedly stronger than these beasts... what does these make em? sage of the 5 paths? if saskuke could pinch kyuubi's chakra like its worth nothing (before he got mangekyou), it does confirm the fact that he could easily control the kyuubi too...if he wished.
Naruto is not a one man army, and this manga has proved that in various occasions. He need his friends, wheres the fun in having and all conquering good natured ninja?
