Kakashi Hatake (はたけ カカシ Hatake Kakashi) is a fictional character in the Naruto manga and anime series created by Masashi Kishimoto. Kishimoto originally planned to introduce Kakashi in the manga to the series' titular character, Naruto Uzumaki, early on, but pushed back this meeting so that Naruto's teammates could be better developed.
In the story, Kakashi is the and teacher of Team 7, consisting of the series' primary characters, Sasuke Uchiha, Sakura Haruno, and Naruto Uzumaki. He is initially portrayed as a detached and apathetic figure, but as the series progresses, his loyalty to his friends and students becomes increasingly apparent. Kakashi's past has been extensively explored in the series, resulting in a gaiden being devoted to his past experiences. Kakashi has appeared in several pieces of Naruto media, including six of the nine featured films in the series, all of the original video animations, and all of the video games.
