The ONLY way Tobi is Obito log logically.

[Megatolium]

I've had this thought long enough (even before Kishi revealed Tobi's face)

What if Tobi used Living Corpse Reincarnation?

A jutsu where the user transfers his soul to a victim's body, and slowly becomes himself while at it, physically too.

Orochimaru is forced to steal body every 3 years, if he doesnt the body starts rejecting him and loads of drawbacks happen.

What if the same thing with Tobi? Since he is from the 1st Generation along with Madara, shown by Madara and Tobi's "knowing each other".

Orochimaru needs to switch bodies every 3 years, what if Tobi can do this every 5+ years thanks to the Hashirama/Zetsu Cells he cultivated in his own body.

Orochimaru while switching bodies he is shown to wear bandages on his face during the process, is this the same reason why Tobi wears the mask?

 

[fati]

maybe

how did Obito grow that tall and get that good to fight the 4th... also Tobi acted like it was the first time he met the 4th...

The only way is Living Corpse Reincarnation.

 

[Uzawak]

Tobi using a Reincarnation Jutsu would just kill it. We've already seen it with Orochimaru, no need for someone else to rip Oro off.

 

[karol the don]

perhaps bra

 

[StaticAge]

That maybe be what happened.

Orochimaru wanting to become like the Rikodou Sennin, knows everything about the Sharingan

Who told him this? He didnt just wake up wanting to be like So6p.

Oh God I hope not, Orochimaru already has it, if Tobi does it will be complete BS.

Well to the first point, living corpse reanimation causes you to take on the physical features of the host body. This is why Orochimaru is shorter in part 2 than he was in part 1 (172 cm in part two as opposed to 179.4 in part one). And he really wasn't all that great against Minato. It only took a little bit of time for Minato to figure out his S/T ninjutsu and exploit its weakness, and then place a seal to remove the kyuubi from his control. In fact the most Tobi managed to do was wrap Minato in some chains, which he used FTG to escape.

However, Tobi using this technique isn't likely. And would severely piss me off if he could. It's supposed to be a technique unique to Orochimaru.
