That's impossible. Remember that not only does " tobi" know just about everything in history, but he possesses the eternal mangekyo sharingan! And he also uses time-space ninjutsu that surpasses yondaime hokage! And Minito himself said that it had to be Madara Uchiha. so there.
wow your wrong on so many levels.....tobi w/ems!? wtf where was i when tobi displayed his ems or hell even ms for that matter??
minato said "madara" was the only one he could think of capable of bla....bla....bla
fact is no one knows who tobi is....
he danm sure isn't tobirama and i would say there's about 33% chance he is madara's soul in madara's original body
32% he is madara's soul in obito's body
33% kishi surprise
1% konohamaru
oh yea and ijust thought of something else that sort of debunks the obi-tobi theory.......
recently we were shown young itachi careing for baby sasuke during fox attack....now at the same time we were shown young kakashi with headband drooping over sharingan......
and we know itachi was older when he took out shisui (when we were shown long haired madara in other non-spirally mask)
so obviously if madara is using obito's body.....he didn't have it then......i guess he could have kept it packed on ice or in chamber......
while restructuring obito's body incorperating hashirama senju's dna to the mix and building the ultimate container to house his soul......uwahhh ha ha ha ha(evil laugh)
ok i'm done babbling here and the last part was just random.....but if that were to become the truth in the future.......remember where u heard it
