Last night, I saw an old episode of Naruto, and it was Kakashi's battle with Zabuza. There it was emphasized that Kakashi is known for being a copy ninja. Can you clarify my thoughts on this? What techniques did he copy? Does he still copy jutsus? Why isn't he copying any jutsu now? Do all Sharingan users have this[JUTSU][/JUTSU] ability?
Kakashi Hatake (はたけカカシ, Hatake Kakashi) is one of the main characters of the series, a jōnin-level shinobi from Konohagakure and the leader of Team 7. He is known worldwide for his use of the Sharingan, earning him the moniker Copy Ninja Kakashi (コピー忍者のカカシ, Kopī Ninja no Kakashi) and Kakashi of the Sharingan (写輪眼のカカシ, Sharingan no Kakashi).
