Naruto Thread (Spoilers For Sure)

Look at you post, now back to Rayquazas'. That is the post you wish your post could look like.

So if Tobi doesn't have a rinnegan (that was his own that he didn't implant), does he not know that Sharingan can become Rinnegan? O_o

My best guess would be that you are unable to use some of the Sharingan techniques with having the Rinnegan one, so its like having a dual charge.
