Mito Uzumaki
MY CASE
-We have seen Tobi use the chain that was used by Kushina to restrict the Kyubi on the Five-Tails-The only other person to possess a rinnengan in the Naruto aside from Nagato is Madara.We must therefore assume the eyes were transplanted from him to Nagato.Tobi was the one who gave those eyes.This seems obvious especially knowing Madara seems to know about Nagato's. Mito existed at the same time as Madara ,she therefore had access to the eyes and she and Nagato are from the same clan.
-She has access to the First Hokage's body which would allow her to use his cells for Izanagi and the creation of the White Zetsu.I am sorry don't have pictures for that.
