When was the first time Kishi ignored facts about the sharingan. I completely forgot about the going blind thing, but now that i heard it, im 100% sold that it's NOT obito. I wish i see ur reaction when u finally realize it isn't Obito. You would really need to stfu.
Tobi wears a mask to hide his identity obviously. People didn't know he had a sharingan because of the mask, and that mask helped him in his fight with Konan, she thought he only had 1 sharingan, but he used that 2nd sharingan that no1 knew about to save his life with Izanagi.
What other Uchiha actually needs Eyes? Either some1 going blind for over using their mangekyou, or some1 who lost both their eyes. Hmmmm, i wonder who that might be.
