A. Danzo - The acting Hokage right now. The leader of the root division of Anbu. Sai's master. One of the corrupt Konoha elder who ordered Itachi to kill the whole Uchiha clan. B. Kakashi - Officially nominated. A respected Jounin and the son of the Konoha's white fang. Student of Naruto's father, the great fourth Hokage, Minato Namikaze. C. Naruto - The town hero. Student of Kakashi the one who defeated Pain and an apprentice of Jiraaiya. The son of the Yondaime (The Fourth) also known as the Yellow Flash of Konoha, the one who sealed the 9 tailed fox in Naruto's body. And the reason why Konoha is victorious in the past war. My choice is Naruto, I think he is stronger than Kakashi and Danzo now, he defeated the six paths of pain using the sage mode and with the help of the sage frogs, even Kakashi died in the battle by the hands of the 2 realm that Nagato controls. Even though he's too young he's strong, even stronger than Gaara the Kazekage. And in the manga series at the episode 455 page 9 the girl from the Kumogakure said that he must be the Hokage.
