honestly i dont agree.Tailed beast aren't even being used and the alliance already seems screwed. They are so lucky Kabuto can't summon minato or sarutobi then it would have really been game over. nice chapter its strange how everyone seems to have some connection to the 9tails. I mean he lost half is chakra and is still the strongest tailed beast and now these brothers have some as well now thats what you call unlimited.
i dont think madara wants to risk losing any of the tailed beasts to the alliance.
if they managed to take more away from him, it would make what he is trying to accomplish even more difficult. I think you'll find him not using the beasts as weapons, its too dangerous. Not only that, I dont think any beast but the 9 tail can be controlled by the sharingan... thats whats been alluded to anyways. I havent seen any evidence of the sharingan controlling any other beast but the nine tail, kyuubi.
you might try to use the madara controlling mizukage - as an example, but he wasnt controlling a bijuu in that situation he was controlling a jinchuuriki...
if he simply released the beasts from the statue, what if they were to turn on him for capturing them? maybe they arent too happy with akatsuki for all we know...
the only thing I can imagine the beasts coming out for is if the former jinchuurikis are summoned by kabuto and then the tailed beasts are released into their possession for use. perhaps as their former containers, they would have some sort of control over them...
other than that, I dont see them making an appearance until the final climax of madara's plan.
as for the kyuubi's chakra... he didnt lose half of it.
only half was sealed within naruto... now that naruto has gone through the process he went through at the temple, naruto has captured the ENTIRE chakra of the fox....
and I doubt that the brothers have more than what sora had...
an excretion of the chakra of the kyuubi. they are dead anyways, so its not like they are still in possession of the actual chakra. if they were edo'd with it, then it is far more plausible that they were created with/from power absorbed from the kyuubi, much the same as sora from the fillers.
the fox is not that hardcore, even though he is admitedly a total friggin monster...keep in mind that naruto (with the help of his mother and bee, true) defeated the entirety of the fox and sealed kyuubi's chakra entirely away within himself..
i also dont agree that minato and sarutobi would have made it game over...
are you dense? do you really think 2 more individuals on top of the cacophony of dead shinobi that have been broght back would make a difference? i don't. granted they were awesome ninja... that I will not agrue. but 4 kages were just summoned, I dont think 2 more would make all that much difference in the face of things.... the alliance still has to deal with madara, he hasnt done a damn thing yet... and sasuke not to mention...
anyways, Im not trying to hate on you, I just disagreed with a lot of what you said in your short paragraph and wanted to explain my thoughts. hope theres no offense taken... well there goes my lunch break. LOL. xd
