Sharingan, rinnegan, Byakugan
Well I was wondering. Madara has a mask with 3 tomoe. The 2 lowest are cut in for madara's eyes.
I was looking for some evidence, but on none of the pictures of madaras mask you could see if the 3rd tomoe is also cut in.
But I was wondering, if it was, it would high-likely be that madara will get the byakugan, and implant it on his forehead. Thus making him the owner of the 3 doujutsu, which could give him some heavy aizen-like powerup
what you guys think!?
