*HUGE SPOILERS IF YOU HAVE READ THE RECENT NARUTO MANGA*
The second I saw him pull out the Sharingan I thought "No, he can't be Obito. Surely not"
But if you look at the picture in the attachment then you can see the similarities. If you have read the Kakashi chronicals then you'll know that he gave his left Sharingan eye to Kakashi and you'll know that most of his body was crushed on the right side. Which would explain the one sharingan and the fact that he is covered in bandages.
Also, they never did find his body.
Does anyone else think that Danzo could be Obito, looking for a bit of revenge?
