i got no problem with uchiha fanboys
im itachi fanboy
but some sasuke fanboys take their love for sasuke too far
Uchicha Macho is too far up sasuke's ass he's lost
EMS is weilded by madara, it alone does not make madara the strongest of kabuto's edos. Just because madara > nagato, doesn't mean EMS > Rinnegan. A lot of people here still think that MS itachi > EMS sasuke.
And if you think about it, the rinnnegan was used by the sage of six paths and he most likely > madara, so by your logic rinnegan is still stronger.
actually as I remembered Kakashi did state it was "rumored" that the sharingan somehow derived or is related to the Byakugan. It even says it in the naruto wiki. but of course this was most likely before kishi even decided to plot in the rinnegan or S6op I think.
