Hiten mitsurugi, despite Naruto's potential, I would still consider Itachi to be the strongest fighter right now. I think they all had an equal chance of being skilled, and I don't think Itachi's family environment was really that much of an advantage to him, considering he killed them all. Kyubi is actually a huge help to Naruto as well, even though it made him an outcast, and took him a while to get used to and mix it in with his own chakra. I think it's a fair comparison and you do not, let's end it at that. Itachi_, what are you thinking? You've already been "banned" once, you should probably try to keep a low profile and not annoy people
