1. Pain
2. Itachi
3. Tobi
4 Konan
5. Kisame
6. Deidara
7. Hidan
8 Kakuzu
9. zetsu
10, Sasori
Reasoning for pain
tobi was shocked naruto could defeat him and called invincible
Reasoning for itachi, tobi thought the uchiha would beat him
reasoning for tobi, he causally dodged attacks from kakashi and the konoha 11 at once while keeping up the goofy holding back persona
reasoning for konan, momentary kept up with jiraya and fought tobi to a stand still
She also was nagato's gf and narratively was a head of the akatsuki, so by portrayal should be strong (same reason stands for tobi aswell)
reason for kisame, he was said as somewhat relative to itachi by aoba and could keep up with gates gai even in a 30 percent clone
reason for deidara, He fought off tenten,gai,lee and neji with no arms and had a high jonin level battle with kakashi and naruto prior to that.
reason for hidan, beat yugito in her bjuu state and killed elite jonin like asuma
later fighting kakasi evenly aswell
reason for kakuzu
He struggled with the chuunin dudes accompanying asuma and co, Kotetsu and forget the other dude's name
reason for zetsu, he fought off dozens of chunnin and chojuro for a bit
Reason for sasori. struggled with kankuro,sakura and sai
literal fodder not even sure why he was even in the akatsuki
