5 Kage and Danzo. Mid high diff
A solos Hidan with one technique, then proceeds to keep punching Kakuzu till he runs out of lives.
Tsunade beats Konan, because she can tank pretty much any attack. Tsunade then beats Sasori because she has perfect counters to his techniques. Then Tsunade solos Zetsu for obvious reasons.
Mei beats Deidara, because her acid on her body instantly melts any bug or any made of explosion release. Mei then beats Itachi, with the help of A.
Danzo beats Nagato with help from Onoki. Onoki can also help Mei against Deidara or Tsunade against Konan.
