Fourth Hokage is the fastest out of all of them, base speed and all variations. Not only wasn't it a feat that a civilian ninja became a Hokage, But he could've taken out Bee and Ay at any point he wanted to, but he decided not to because he could tell Bee was a special guy.
Minato excelled at multiple things, including ninjutsu but speed was certainly his biggest asset. He was known to be the fastest ninja of his era and he was much faster than the likes of Ay, even in his natural speed.
All of Hashirama's Wood Release techniques wouldn't be much help if the Fourth Hokage can just teleport around them. Minato can also attain a powerful Sage Mode akin to Hashirama's, albeit even more intense. The Fourth Hokage's speed, maneuverability, and ninjutsu capabilities would almost certainly give him the win.
1 The Yellow Flash, Minato Namikaze
Like Tobirama, Minato also masters the Flying Thunder God Technique. Minato even possesses greater control over the technique, using it to earn the nickname The Yellow Flash. He is considered the fastest shinobi of all time and gained worldwide recognition for his abilities.
Minato, rasengan creator, hailed as the fastest shinobi of his time and a better FTG user than Tobirama, its creator.
Minato has the Kurama form but still he can't beat Kakashi with the Susanoo and kamui. Minato wins because due to Kakashi average chakra reserves he can't hokd out PS for too long. So he'll run out too quickly.
Madara was stronger than Tobirama when the two of them were alive. After the former was reanimated by Kabuto, there was simply no comparison between the two. Madara gained the Rinnegan and then he became the jinchuriki of the Ten-Tails.
Naruto Uzumaki has grown a lot since the series first began. Currently, he serves as the Seventh Hokage of the Hidden Leaf and holds the title of the "Strongest Ninja in the World." Naruto has access to Six Paths powers, which give him a significant boost against his opponents.
Undoubtedly the strongest shinobi of all time, Naruto Uzumaki was perhaps the biggest reason why the shinobi war was won. Like Sasuke, Naruto entered the war pretty late, mostly because the truth about the war was being kept hidden from him.
Kaguya Otsutsuki was the strongest known character in Naruto who was a master of all the arts, including genjutsu. Like Madara Uchiha, Kaguya had the power to cast the Infinite Tsukuyomi, a powerful genjutsu that trapped the entire populace into a world of illusions.
Minato possessed enough power to battle the Nine-Tails and Obito Uchiha in succession and still emerge victories. What's more, during the war, he gained access to the Yin half of Kurama, making him far stronger than Pain could ever be.
When Might Guy opened his Eight Gates, he became invincible and nearly defeated Madara Uchiha in his Ten-Tails Jinchuriki form. In this state, he can easily overshadow Minato's speed, and with his single kick, he can obliterate Minato's body.
While there is no doubt that the infamous Konoha's Yellow Flash, Minato Namikaze is the fastest shinobi in the world. However, Naruto's rigorous training and utilizing his immense chakra reserve to a greater extent enhanced his physical capabilities.
Hiruzen Sarutobi was the Third Hokage and picked up the role again after Minato's death. He was the longest-reigning Hokage and ran the village quite smoothly. He is the Hokage for the majority of Naruto and the first one that viewers are introduced to.
Madara can react based on his feats. We have seen him reacting to characters faster than him multiple times, like KCM Naruto who is faster than the Raikage who is faster than Madara. Tobirama was the fastest shinobi of his time but he had no chance in hell defeating EMS Madara .
Konoha's Yellow Flash, Minato Namikaze, was the fastest shinobi in his lifetime. He possesses natural speed and dominant skills that foreshadow the capabilities of his powerful opponents. Minato mastered the Flying Thunder God technique to such an extent that he surpassed its creator, Tobirama.
As an Otsutsuki member, Kaguya is the strongest character in the Narutoverse. However, after consuming the entire Chakra fruit for herself from the God tree, she attained godly feats, making her an unstoppable force in Naruto.
Who are the gods in Naruto? Jashin is a god whose presence has little to no origins. He was first introduced by Hidan in Naruto Shippuden, and was the source of his immortality. According to Hidan, Jashin's ideologies center around violence and blood sacrifice.
Jiraiya. Jiraiya was an exceptionally competent shinobi, and he was the only member of the Legendary Sannin who could actually beat Itachi. He was trained by the Third Hokage, and learned how to use Sage Mode while training with the toads of Mount Myoboku.
Black Zetsu was central to one of the biggest shocks in Naruto during the 4th Great Ninja War. It was he who stabbed Madara Uchiha in the back and struck him down when he was at the pinnacle of his powers. Zetsu was then revealed to be the perpetrator of the plan to bring Kaguya back.
In conclusion, Obito Uchiha would defeat Itachi Uchiha when comparing the two characters in their strongest forms. Obito has one of the strongest, if not the strongest, Sage Mode in the series and has enough chakra reserve to beat Itachi.
Like Obito, he became the 10 Tails Jinchūriki in the Fourth Great Ninja War. Madara was much stronger than Obito to begin with, and the fact that his version of the Ten-tails was perfect made him even stronger. When compared to Madara, Obito stands absolutely no chance.
