in your opinion who has the biggest killing streak in the series so far?I mean during their lifetime and with their own hands so with no manipulation or controling others.
I think orochimaru and kakuzu would be the ones with the most kills.
it is known that you need both the sharingan and the senju dna to develop the sharingan into the rinnegan,but when you get the rinnegan and for example transplant it to another person and you get yourself a new pair of sharingan eyes, can you develop them again into the rinnegan?
some people say that obito was under madara's genjutsu when kakashi killed rin,it is known that you need to kill a close person to you so you can unlock the ms but how did obito and kakashi unlock the ms if they haven't killed her?
