ABC logic wont work in Naruto ......top ten list is made depending upon how the charecter can defend himself as wel as defeat the ppl below his rank in top list.........
my top 15 are
AM excluding EDO since it is wise to put thire own battle strength while comparing individuals
1.Juubito
2.Madara/Hashirama

it is wise to say Madara >Hashi but Hashi had knwledge on rinnegan which make's rinnegan almost useless)
3.EDO Minato

What he lags to be on par with Hashi and Madara is chakra now he had a lot of Chakra so it is acceptable)
4.BM Naruto/Nagato/DSM Kabuto/Alive Minato
5.EMS Sasuke/EDO Itachi
6.Alive Itachi/Jiraya
7.Tobirama
8.Orochimaru
9.3rd rikage/Bee
10.Muu/2nd Mizukage
11.4th Rikage
12.Onoki/3rd Hokage
13.Kakashi/
14.Tsunade/Mei
15.Gai/Darui/Most of Akatsuki members
Sorry if I forgot some one.........
