|Tobi is Obito because in his mask there is a hole on da same side where he still has his eye. His name is just twisted around without 1 of the O's. And he has a something wrong with his body or something because like half of it is fake. And it was Orochimaru who revived him so he could get his Sharingan but he only had 1 so he left him alone. And he is da same age as Kakashi. And he has da same hairstyle 2. And da reason he is with da Akatsuki is because he dosent remember anything so dats Y he is a bad guy (For now)|
Okay I'm going to put up a couple of pictures...and then will you explain how somebody could get out of there.
First up we have Obito with a boulder on half of his body (including this eye that is some how still supposed to work)
And here we have an avalanche of boulders falling on what little bit of his body wasn't already crushed by the first boulder
So for Tobi to be Obito someone would have had to:
1. Known that Obito had awakened the sharingan which happened during the mission.
2. Known where the rock nins had buried him.
3. Known how to give him a replacement body (I'm sorry but nuts and bolts aren't going to cut it if someone's been buried under half a mountain).
4. Wanted to go through all the effort of steps 1-3 for a fairly crappy ninja.
