Who's leg could it be??? Karin has no idea who it is so kabuto is off the list... It can't be anyone we have seen in the war, so who is it??? Well, here's my opinion... The man is sasuke's father.... Think about it. Itachi thought he killed his father but didn't because his father used izanagi... Itachi didn't know about izanagi at the time so it is a very good possibility.. If you are wondering why his father didn't show up earlier, it's because he was a rogue ninja and didn't want to appear until he knew the time was right.. I don't know how he will be able to bring sasuke back to life.... Any opinions????
