1rd) Kabuto Yakushi: edo tensei + DSM + tactician + best healing ability's shown thus far in the manga + 2nd largest summoning in the series(manda II)
2nd) edo Madara: Rinnegan + Makuton/Senju DNA + edo + PS + pure boss
(some may be confused as to edo Madara's placing because he originally was apart of Kabuto's arsenal but once Kabuto's edo tensei was released he sealed himself, Meaning he is in fact his own edo.)
3rd.) Obito: Kumui + Rinnegan + 6 jins path's(7 bijuu) + Makuton/Senju DNA + Gedo Mazou
(I had such a hard time decided who should have been placed higher Obito or Madara hahaha)
4th.) Nagato: The most skilled user of the Rinnegan + Gedo Mazou
5th.) Hashirama: "fairytail" + Senju + Makuton + was known to be on = if not greater fighting terms then living Madara + healing capability's = to Tsunade
6th.) Naruto: variations with Rasengan + mastery of Shadow clone jutsu + SM + perfect Jinjuriki + many toad summons
-->Oh man 7 through 10...these ones are where I hesitate because it gets more difficult<--
7th.) Sasuke: variations of lightning bassed jutsu + Kenjutsu master + quick thinker + blaze release + EMS
(I know I am going to get allot of people getting pissy at me for Sasuke's placement being as low as it is. But untill we see more of his EMS this is where he is in my opinion.)
8th.) Sasori: the greatest puppet master shown thus far + kazakage puppet + being a puppet meaning he feel's no pain + his collection of about 298 puppets + all weapons ate dipped in poison + conquered a nation.
9th.) Ginkaku & Kinkaku: able to use up to 6tail's each + sage weapons + great tag team
10th.) Hanzo: able to defeat the Sannin with what seemed to be little difficulty if you look at his body he did not seem damaged or warn out in the least + poison weapon + Ibuse
(You could argue that the Sannin where younger/weaker when they fought Hanzo but I dought they was much of a difference)
