My art teacher has asked what is the best naruto character other than naruto explain

Yamato

Explanation:

Yamato's abilities introduced a major question to the story of Naruto. He was first introduced after the time skip when he was chosen to act as the temporary leader of Team 7 while Kakashi recovered from his injuries.

Yamato was chosen due to his ability to suppress the chakra of the Nine-Tailed Fox, in case Naruto lost control again. It was never explained why he wasn't put in charge of Naruto from the start, considering the numerous circumstances under which Naruto could have lost control and set the Fox free.

Yamato's ability to suppress the chakra of the Fox, as well as regular chakra, makes him one of the few people who can contend with Naruto's powers after he finally made peace with Kurama and gained access to his abilities.

Yamato could therefore rob Naruto of his biggest trump card in combat.
