1.Kakashi-stern and seriousKakashi has a rather solitary, and matter-of-fact attitude. His calm and detached demeanour has been called "cool, hip, and trendy" many times by Might Guy. Despite his increasingly growing reputation and prowess as a ninja, Kakashi has shown no signs of arrogance,His naturally calm attitude is used to his advantage in battle, as it becomes easier for him to maintain his composure and stay focused on the situation at hand, and notice everything around him. As a result, he can quickly adjust to any situation to make keen and thought-out decisions, allowing him to stay steps ahead of his opponents.Kishimoto said that if he were to make an extra story from the manga with a different character, such character would be Kakashi.Thread/
2.ItachiEver since his first appearance, Itachi had always been inscrutable. Unlike the vast majority of his clan, Itachi was not interested in personal gain, caring more for his village as a whole. Flashbacks showed that he used to be a compassionate brother
Itachi was shown to be highly intelligent, something even Tobi acknowledged. From a young age, Itachi was very astute with a great respect for the past and his personal history. From this, by the age of seven, his wisdom and understanding of the world was on par with the Hokage, as noted by Hiruzen Sarutobi. He was quick-witted, observant, and intuitive; rarely being caught off guard or deceived.
