Thats cool and all but im still waiting on someone to tell me what he will do against...
against Flower world? What can he do against Bringer of darkness but use death reaper seal and kill himself? How does he get through any of the raikage's lightning sheilds? How does he beat suasnoo or itachi genjutsu? How does he even touch minato, BM naruto or obito?what does he do against madara's suasnoo? What does he do against planetary devastation?What does he do against kakashi's mutiple elements and sharingan which give him to power to easily counter all hiruzen jutsu's, and counter him in taijutsu, or kamui? How does he get passed Gaara's defense and escape all his sand or catch him in the air? What does he do against dust release?
Cause known of the leaf's jutsu's we know of will beat these jutsu's, and if he had such great jutsu's he should have showed them by now. He's the only one shinobi who's suppose to be so strong but he's showed no great jutsu or genjutsu, he has like no feats in fights
We Havn't seen all of Hiruzens Jutsu Pools, Not even close to. We've seen None of his 1000 + Genjutsus, almost nothing of his Nin, So we cannot say he say Counter Jutsu's like Flower world. But he has knowledge on it and other jutsu's hashirama uses.
Also he was stated to be the strongest of the 5 current kages (in Part one), Even in his old age, If he is Kage level in his old age (when he was stated to be pathetic in his old age), His Prime is easily on the highest end of Kage level.
Hiruzen couldn't show his Best Jutsu's, Again if you would read what my post said, His chakra levels were low in his old age, He didn't have the chakra levels to use Large scale jutsu's, He barely used any jutsu's and tired very quickly.
As for what you said about Kakashi, Hiruzen Has a Larger jutsu pool than kakashi. Also Hiruzens Taijutsu/Genjutsu is superior to that of kakashi's.
Old Age hiruzen scores a 5 in Taijutsu, While kakashi only has 4.5, Hiruzen has 5 in Genjutsu, Kakashi has 4.
Kishi Stats Hiruzen has Mastered all the shinobi arts, So hiruzen has mastered Nin/Tai/Gen (a feat that no shinobi has ever done), he doesn't need feats to prove it when kishi says it himself.
Also all your questions, I can ask about Hashirama. Hashirama hasn't shown anything to be able to Touch minato/Bm naruto/obito or defend against planetary devastation.
