For everyone saying out there "maybe tobi have nagato the sharingan and he awakened the rinnegan" no just no. If nagato first reciveded the sharingan he would have to get MS and EMS before he awakened the rinnegan so that is sooo flawed.
And If you are trying to say that he gave nagato EMS :sy: then he would be able to do some or at least 1 sharingan ability. Also he would be able to switch back and fourth between his EMS and rinnegan.
The only eye we have seen nagato with is the rinnegan, this supports it was implanted.
The only ablities we have seen nagato perform are rinnegan abilities, this supports it was implanted.
If you know that it is obvious tobi did not give nagato a sharingan :sy: don't post this thread is not for you. I have seen a few people saying this it needs to stop!
