Kyūbi Naruto, also romanized as Kyuubi Naruto, is Naruto's Final Smash in Super Smash Flash 2. Naruto's Final Smash is to, almost unwillingly, go into his Kyūbi Form. In this state, he can use the powers of the dreaded Kyūbi no Yōko (九尾の妖狐, Nine-Tailed Demon Fox), Kurama, a terrible beast with unheard of power. All of Naruto's techniques are severely overpowered in this form.
