1, naruto Uzumaki.
Reason: Naruto has always been a "crane tail" in Ninja School. After graduation, he and Sasuke were assigned to the same class, led by Kakashi. They don't like each other, but Naruto can't beat Sasuke. Later, Naruto got rid of the title of Hewei through long-term efforts, and the villagers gradually recognized him, and his best friend Sasuke also recognized his path.
2. Maito Gai.
Reason: Maito Gai's ability was poor when he was young, and he failed in Ninja School. Fortunately, the three generations saw Kay's potential and made an exception to admit him. Later, Kay climbed to the top step by step with her own efforts.
3. Uchiha Obito.
