Curse of Hatred wrote: I think that the Rasenshuriken is different though. While the initial technique was created by Minato, Naruto made the Rasenshuriken so it's his jutsu. So regardless of its power or often it's used, I would consider the Rasenshuriken a signature technique because Naruto is the creator. True. there's Minato, Jiraiya, Kakashi, Naruto and Konohameru who can do Rasengan. But only Naruto can do Rasenshuriken.

Its somewhat similar for Kagebunshin. Others used the techniques, but nobody made it as fundamental to his strategy as Naruto.
