There is only one logical conclusion, Tobi power and Kakashi power in their eyes work on the same principal,how? We know Kakashi got His Sharigan from Obito, so could Tobi be related to Obito if not Obito it self?I have never ben an Obito is Tobi proponent at all, I have railed against such theories in the past, But with Tobi and Kakashi Sharigan powers working on the same principle, I can't help but wonder?
