Now we all have heared rumors of tobi's identity being izuna, obito, or some other random dude.
Fact of the matter is though, tobi was doing a poop while itachi kiled the clan, when he was done he took a stroll cus it smelled pretty bad and everyone was dead. So he was like pretty pissed that his uchiha plumber died and couldnt fix his toilet after his massive poop, and was like skrew this shit i demand peace.
Clearly this is what really happened.
