I genuinely believe Hiruzen can beat Kakashi without the sharingan and Tsunade. But feel free to prove me wrong bro
Hiruzen did teach Tsunade and she has more skill than her along with all the other Hokages that ever existed but my thing is that Tsunade is of senju lineage, a clan gifted with longevity and physical energy of the Sage. She's so persistent that she was split in half by wood style yet she still reattached herself together.
I don't know where Kakashi genuinely stands because he just lost his mangekyo powers, however Tsunade on the other hand I don't see Hiruzen beating her because he doesn't have any jutsu to permanently put her away.
Between Hashirama, Tobirama, and Minato which ones do you see Hiruzen beating in a fight? I can you also explain on why too?
