The Unbreakable shield is the Susano. And alright I just meant he had more chakra then the original Fox aura Naryto not Tailed Naruto. (When he fights Haku) What Neji said was at 30% as well if he used all of it he would probably be stronger then most of the Akatsuki (Minus Pein, Itachi, and Tobi)
EDIT: Revised list since I've seen more.
STRONGEST:
1)Tobi/Madara
2)Itachi
3)Pein-Numbers 2 and 3 could change around.
4)Kisame
5)Kakuzu-He is very smart and deadly. Kakashi almost dies to him which is why he goes lower then Pein since he did kill Kakashi...
6)Sasori-Deidara did say Sasori was stronger then he was.
7)Konan
8)Hidan
9)Deidara
10)Zetsu-I know we haven't seen him fight but his skills seem as though he is only really good at spying. This could change once we see him fight but for now that is where I put him.
FAVORITES:
1)Kakuzu
2)Itachi
3)Kisame
4)Hidan
5)Sasori
6)Tobi/Madara
7)Pein
8)Zetsu
9)Konan-She doesn't fight
10) Deidara
