So after all, is this option is right
Option 1
A) Oro is back in some kinda alive state, spare between the masked man and the snake part within Kabuto !!! check
B) we learn that rinnegan is the advanced state of sharrigan eyes, cool.
C) oro wasn't plannning to ovecome sasuke's body + overwhelming power of uchia madara !!! **** that bastard will overcome everybody if he got the chance to get sasuke.
option 2 --
Or somebody else is tobi and manage to take over the world and oro is only the snake within kabuto.
but if that so, explain me what's below ..
What's is coming in mind is closely possible that is was Orochimaru who gave the rinnegan to Nagato during the great 3 war, as an experiment or something...still tobi has told us it was him who gave the rinnegan to nagato... That would make option 1 valuable !!!???
KISHI your use of the word " his" makes it really confusing loll
