In Naruto, no matter how strong the master is, he sometimes misses. For example, Sasuke Uchiha was completely abused when he went to catch the Eight Kingdoms, and Naruto was defeated if he didn't start the fourth-generation insurance measures in World War I with Payne. Kakashi claimed that he had his eye cut off in the same year. However, there are so many ninjas who have never lost their lives.
1. Senju Hashirama
Senju Hashirama, the leader of the clan with thousand hands, the ninja god who ended the troubled times of ninja and founded the system of one country, one village, and the founder of Konoha Ninja Village, was the first generation of Naruto. Just look at these titles and you will know that the pillar is definitely the top existence in the ninja world. Unlike Naruto Sasuke's cp, the first duel between Naruto and Sasuke was actually Sasuke's victory, and the final duel was both losses. Senju Hashirama has never lost to anyone, including Uchiha Madara, who controls Kyubi no Youko Fox.
2. Uchiha Itachi
Uchiha Itachi may not be the strongest Neiguang family, but he has never lost. Spotted leaves were lost to Black Jue He, so they stopped water in an instant and forbeared, or capsized in the gutter and lost to a sarin cadre of the team. Sasuke left alone and basically didn't win. The skunk god who is so strong in soil is also afraid of him and never dares to confront him head-on. He can only remain vigilant; Hiding can stop the water, but the ferret god has never had a defect. As one of the three, orochimaru was killed at a glance by the Ferret God. Bijuu, the so-called tailless ghost shark, can't resist the illusion of the ferret god. Moreover, the Skunk God not only won in his lifetime, but also became Lianke Nagato and immortal Yakushi Kabuto after the reincarnation of the filthy land, and there was no one after this record.
3. Namikaze Minato
Namikaze Minato, the fourth generation of Mu Ye Village, the legendary golden flash, is a superhero who single-handedly reversed the situation of the Third Endurance World War. Namikaze Minato once fought against more than 50 enemy elites with one hand. Elite forbearance is the title of ninja like Kakashi, and even Asma, once one of the twelve guardians of fire nation, can only call it forbearance. In other words, when Namikaze Minato was in Huo Ying, he defeated 50 Kakashi who didn't have a 50-50 halo. Namikaze Minato single-handedly confronted Lei Ying and the eight-man column, but he didn't fall. In the face of Uchiha Obito, whose ability is unknown, Namikaze Minato was also killed. Namikaze Minato's strength mainly depends on its high speed and high fighting wisdom.
That's my answer.
