strongest kage to have ever lived?

[Dęvîa Puęrî]

Naruto in the Future but as of now Hashirama and Minato comes second.

Minato alive would not beat Mu or 3rd raikage and tobirama is debatable as well

So yeah minato can take several seats

 

[KingHashirama]

First of all, we don't even know the strength of the badasses of the First and second generation Kages..


And out of the ones we do know Hashirama and Tobirama take the first and second.
