geez..I quote my other post for another dude who thought that:
"lmao
No he isn't Izuna.
Firstly, Izuna died before Madara vs Hashirima. And everyone in Konoha knows Madara fought the 1st.
Secondly, Minato said "only one I recall who can use space-time ninjutsu on that level is uchiha madara"
Thirdly, tsuchikage has obviously heard madara's voice when he fought him in the past and he didn't say any objections when he heard "Madara"'s voice in the kage meeting.
Fourthly, Itachi believed him to be Madara so I guess him and Minato are pretty dumb?
Fifthly, no one else but Madara in the history of uchiha haven't been said to be able to control the kyuubi, like Tobi did, before he kidnapped Naruto. so again tobi = madara
Sixthly, Danzo called Tobi Madara
Lastly, WHY WOULD IZUNA POSE AS MADARA!?"
and it was stated that izuna died in battle without having his eyes..so anything else?
