Where did Danzo get the Sharingan?
Who’s not got surprised when Danzo revealed his Sharingan? Apparently, he’s been hiding it under the bandages and it seems like he has never used it before. He’s currently the declared 6th Hokage and he’s heading to the meeting.

Danzo
Now Tobi (Madara) always wears a mask and only shows one Sharingan, but he’s showing the right eye. So technically, we got 2 right sharingan eyes here, one on Danzo and another on Madara. However, Madara’s eye was damaged before, causing the transplant from his brother Izuna. It’s not very clear to me whether he damaged both eyes but one thing for sure is that there’s another possible source where Danzo got his sharingan from. Danzo’s sharingan is a damaged sharingan so I am very much positive that it’s Madara’s old eyes or Izuna’s. And it’s also possible that it’s the main reason why Sasuke is on he’s way to kill Danzo. Madara and Sasuke had a heart-to-heart talk before and I’m suspecting that Danzo’s sharingan was one of the topics.
But there’s more… Uchiha clan was murdered before and there were a lot of eyes Danzo can choose from. hmmm… but I highly doubt it too. During the murder, Sasuke is already a kid and again, judging the picture above, it looks like it’s very long time ago when Danzo was very young.
Guys, these are only opinions and yours are welcome too.

i think that danzo is madara because all of the facts r there the sharingan in the right eye both r very old and i have the solution that every one has been wondering why did kisame called madara the mizukage? it is because danzo aka madara used the sharingan on him and if u read the new manga it said that danzo got his sharinggan from uchiha shisui and it said that he had the power to get into peoples mind so i think that he probobly got into kisames mind and made him think that he was the mizukage so that kisame would relly on him more and besides and i think that there is no madara and he just made all that up so no one would suspect him and thats how he proboly controlled the fourth hokage with his sharingan making him believe he was madara but he was really danzo
tell me wat u think and if you want to add anything to it just right a comment
