From a young age, Itachi was calm and insightful, showing noticeable maturity for his age and knowledge on how to deal with every situation. For all his accomplishments, talent, and fame, Itachi was a rather humble man. Never arrogant about his own abilities nor underestimating others, most things he said would be unbiased and accurate. If an opponent exceeded his expectations or posed a legitimate challenge to him or his allies, Itachi would freely admit it.
