Lo.l literally got on NB to see if a theory would be up about this and it's the newest thread. I didn't read yet but I think there is some connection too. Has to be some reason madara's staff looked like that and that he has 1 horn and Obito had 2 and a different staff but less tailed beast chakra? Still confused as to how obito has yin yang release
His horns are not the same though. One is on his forehead, the other is further back.Madara has 2 horns...
It is his Staff that is incomplete...
