lets just say it's a good sign of Kishimoto's ever growing lazyness of detail...
but a proper answer would be that, it's probably just a cloak nothing more, the proper host of the nine tails would only be the one to portray these attributes
apparently this "Blitz3d" is famous enough to put his name at the start of his threads...
i thought "Dr Proof" only had that authority
EDIT:
nah im joking anyone can...
BUT it doesn't feel the same coming from someone who is less informative, when theres a "Dr Proof" at the title of a thread...
pretty good tho sasuke shouldnt have a trace of confidence when saying "lets go meet this uchiha madara"...
other wise madara wouldnt hesitate to make an example him
i don't think the kages would be of much use again...
madara allready made an example of them
but it is still possible and a good prediction none the less
