This is going around in my head again and to me seems more likely than tobi being obito....Itachi says to sasuke you have to take your brothers eyes to get eternal sharingan...yes we have ''Madara's'' story of taking his brothers eyes. We also have the quote from the manga saying ''I have Uchiha Madara's power'' i think with the younger generation following in the past generations footsteps would it make sense for the younger brother to kill the older one?Izuna to kill Madara (as they were equals?),just like sasuke did itachi???Then Izuna pretending to be Madara?Just thought I'd see what you guys thought
