Minato

Prime Hiruzen

Hokage Kakashi

Onoki

War Arc Tsunade

Maybe Mei

Mei would have a lot of trouble against pain tho

Definitely not kakashi, tsunade, or mei. They got nothing to survive some of his rinnegan abilities like imagine if pain summoned a meteor

There’s no way Mei is beating Pain, and if Sage Jiraiya couldn’t do it, neither could Tsunade. Just sayin’

DMS Kakashi definitely stands a chance.

DMS wipes the floor with Pain, mid diff at the very highest.

Kage kakashi doesn’t have sharingan

I already adressed that issue earlier.

But the question is Kage at their prime or at the time they were Kage? That's not necesseraliy the same thing.

Pain can't summon meteors

Hokage:

Harishama (Duh yes)

Tobirama (Very High diff but he could get a teeny chance of winning)

Hiruzen (Prime Yes Old no)

Minato (yes but Mid diff)

Tsunade (No even though she can beat jiraiya she cannot beat Pain)

Kakashi (DMS Yes Hokage High diff but he could win)

Naruto (Not gonna say anything)

Kazekage:

(None of them)

Mizukage

(None of them)

Tsuchikage

1st (No)

2nd (Maybe?)

3rd Maybe?)

4th (No)

Raikage

1st (No)

2nd (No)

3rd (Mid diff but he wins)

4th (High diff but could possibly win)

5th (Very High diff but again could possibly win)

That’s my Opinion
