All ninja referred to as Hokage, ranked

[The Messiah]

But he was able to use ET when they first fought and he did and lost so you need something better then he can use ET .. that was a sasuke who just passed out minutes ago and besides that I can't see him beating any of the people under him definitely not jman or tsunade and I'm not even a fan of hers but like I said before everyone got their own opinions

Orochimaru beat Hiruzen.

Sasuke fought Danzo after being healed by Karin in the kamui dimension. Danzo beats all the people below him with izanagi and paralysis seal.

Tsunade(11)
Konohamaru (14)
Danzo(7)(maybe 10-11 w/o sharingan)
Kiba (13)(maybe 11-12)


All known, self proclaimed, aspiring, referred or predicted to be Hokage strongest to weakest

Disclaimer:
Kakashi is post war.
Obito is one sharingan eye and Hashi half.
Danzo I'm not counting his countless sharingan.
I'm estimating Sarada's likely power in her prime.
Konohamaru despite his lack of badassery in Boruto thus far I'm giving him the benefit of the doubt.
