Tobirama was the most intelligent Hokage ever to rule the Leaf. A ninjutsu genius, he created powerful forbidden techniques such as the Edo Tensei and shadow clone jutsu.
2) Kakashi
He is arguably one of the smartest Hokage the village has ever had since he was pivotal in restoring the village after the Fourth Great Ninja War. He was also responsible for laying the foundations of the technological era.
8) Naruto Uzumaki - Seventh Hokage
He is the reason behind the peace in the Shinobi world, an accomplishment even the God of Shinobi, Hashirama Senju couldn't manage to acquire. Naruto is by far the kindest character in the series.
Naruto Uzumaki, the Seventh Hokage of the Hidden Leaf Village, is without a doubt the most powerful shinobi to hold the title.
With Naruto Uzumaki, the Seventh Hokage, being considered the strongest of all time, it is quite clear that the weakest of all Hokage is one of Kakashi Hatake and Tsunade Senju.
When discussing the worst Hokage in the series, the ones that should be taken into consideration are Hiruzen Sarutobi, Tobirama Senju, and potentially, Tsunade Senju. While the general consensus is that Tsunade has been the worst Hokage to ever appear in Naruto, that is far from the truth.
Minato Namikaze is the fourth Hokage of the leaf village. He was also known as the yellow flash of the leaf. Minato was a very humble and collected man.
Natures. Hiruzen Sarutobi was the Third Hokage of Konoha and the longest serving Hokage. He was the husband of Biwako Sarutobi, father of Asuma Sarutobi and grandfather of Konohamaru Sarutobi and Mirai Sarutobi.
1) Itachi Uchiha
This child prodigy became the Anbu Squad leader at the tender age of thirteen and carried out one of Konohagakure's most secretive operations. As portrayed in his fight with Sasuke, he is also shown to be an astute and competent planner, foreseeing and assessing everything before entering combat.
Based on the universe he's in and the standards set within it, I'd estimate between 130–160. He's a genius but he's also emotionally stunted. He catches on to concepts and observations pretty instantly and can formulate proper responses and apply solutions on a short whim.
4) superior intelligence: yes Tobirama is smart, but Itachi is much smarter.
Senku Ishigami is believed to possess an IQ of 180 to 200, making him a highly gifted being. He holds a profound knowledge of chemistry, mathematics, physics, biology, and all other subjects. Using his wide sense of knowledge, Senku has proved himself to be the savior of humanity multiple times.
In the databook Sakura has an IQ of 175. That's higher than most anime characters.
Neji is supposed to be a genius and characters like Asuma and Jiraya score a 4.5. While characters like Itachi, Hiruzen, Minato, Shikamaru, etc score a 5. Hidan himself score a 3 higher than Lee, Choji, and probably a few others. Neji the genius scored a 2.5 in original Naruto and a 3 in Naruto.
3 WEAKEST: Onoki (Third Tsuchikage)
Onoki is a character that is easily underestimated and overlooked. His age and looks are not the reason why he made it on the list of weaker Kages. But rather, his temperament and his willingness to let it control him.
With his signature technique, Flying Thunder God, Tobirama Senju was the fastest character in Naruto. But a few have now been able to beat the Hokage. Tobirama Senju is one of the most popular characters in Naruto. He succeeded his brother as the Hokage of the Hidden Leaf.
Jonin Commander (上忍班長Jōnin Hanchō?) is the title given to the highest-ranking jonin of Konoha. This shinobi is capable of representing all other regular shinobi of the village, for instance when a new Hokage needs to be chosen.
Hashirama, Tobirama, Minato, Kakashi and Naruto. These are the Hokage that can beat Pain individually.
To further illustrate this point, the First Hokage had a brief rematch against Madara during the Fourth Great Shinobi War, and he was easily beaten by Madara. By contrast, Naruto could at least put up a fight against Madara, and Naruto would almost certainly put down the First Hokage with ease.
Tobirama Senju was not fond of the Uchiha right from the Warring States Era. While his hatred for his enemies was justified at the time, when he became the Hokage, he should've been able to look at them differently.
Kakashi is a very fast, and shrewd shinobi, so for him to let Tsunade hit him in the head is preposterous. Furthermore, Kakashi's offensive powers, such as Kamui, far surpass that of Tsunade's. If the two ever fight, Kakashi would emerge as the victor.
There is no doubt that Kakashi is quite strong despite the loss of Sharingan. He is by no means weak and can hold his ground against tough opponents. Whether it be his ninjutsu, taijutsu, or shuriken jutsu, Kakashi has mastered them all.
