if you don't remember,I will remind you:Dont tell me you are one of those people who say TOBI=OBITO
Yet to see proof of if TOBI does that by ability of MS
Well till now putting out Amaterasu is shown as ability of Sasuke MS alone
besides there are numerous way of putting out Amaterasu.
tobi could cut his hand and regrow just like he did in case of Danzo's henchmen
Thats no reason even Sasuke was able to enter and meet 9TAILS in the first few chapters of shippuden that too without MS. its not necessary to control bijuu with MS. It requires feats to do that with Sharingan
1)talking with bizzu and controlling it are completely different levels...
2)sasuke said:"so that's the price you have to pay for taming kyuubi"he meant blindness due to MS.
3)bizzu are not something you can control with normal level genjutsu...they require very high class genjutsu...and kyuubi...most strangest of them...without MS,you are out of league...dude!
