I have to disagree with some of these simply from what has already happen.
Naruto has already defeated Nagato and that was before he gained KM and BM, the three Sannin were defeated by Hanzo, Mifune defeated Sannin, Sasuke has always had luck on his side in his fights everyone was sick or holding back, Itachi he has proven himself over and over being able to handle many situations without and difficulty but there was a reason he never took on Tobi, Madara from what we are seeing with mukoton is EDO so i don't count them. Here is my list
1. Sage of six paths (jubi, rinnegan, pure power)
2. Madara ( ems, rinnegan, kurama)
3. Naruto (kurama, sage mode, BM, Toad Summon, Rasenshuriken)
4. Nagato (rinnegan, six paths)
5. Hashirama (mokuton, outdid ems Madara)
6. Minato(speed, outdid no rinnegan tobi+Kurama)
7. Itachi (ms, izanagi, summons crows)
8. B (eight tails + Kenjutsu)
9. Kabuto (sage mode, edo tensei)
10. Sasuke (ems, hawks,)
11. Mei Terumī (Boil, lava, and mastered 5 different nature types) (melted Susanoo)
12. Jiraiya (sage mode, toads)
13. Tsunade (slugs, super human strength, seal on forehead, medical ninjutsu)
14. Hiruzen (monkeys, powerful)
15. Orochimaru (edo tensei, 8 branches technique, snakes)
Itachi > Minato. Mid difficulty
Sasuke > Minato. Mid difficulty
3rd Raikage > Minato. Low difficulty
Mu > Minato. Mid difficulty
This is wrong
Minato =/> Itachi (Hard to say be a high level fight but Itachi would be blind)
Minato >>>> Sasuke low difficulty (What has Sasuke really done?)
Minato > 3rd Raikage (3rd Raikage couldn't catch Minato)
Minato > Mu High Difficulty (Simply because if he gets marked there is no stopping Minato on him even if he was to fly)
