Akatsuki vs Five Kage

[Guardian of the Rain]

No restrictions
All out battle, everyone going apes***!
Akatsuki are alive and healthy

 

[Ultimate Beast]

Akatsuki easily

 

[Kettei]

Akatsuki easy

 

[9Bijuu]

Akatsuki with little difficulty at all. Even assuming they were all somehow killed, Hidan can never truly die so once he out lives the kages it's an Akatsuki win either way.

 

[Akatsuki wise guy]

akatsuki easily heck nagato can probably solo.

 

[Turson]

Akatsuki, isnt it obvious?

Pain - Kage level
Itachi - Kage level
Sasori - Kage level
Deidara - Kage level
Kakuzu - Kage level
Hidan - Jounin level
Kisame - Kage level
Konan - Jounin level

Zetsu is not a fighter, but these guys above would be far more than enough.
