Kyūbi Naruto

Kyūbi Naruto is Naruto's Final Smash in Super Smash Flash 2. The transformation begins with a powerful burst of chakra revolving around Naruto. Afterwards, you will control Naruto using the Kyūbi no Yōko (九尾の妖狐, Nine-Tailed Demon Fox) chakra. All the physical traits of Naruto are altered, including the black rings that surround the more berserk-looking eyes. In this form, Naruto could use his elongated, sharpened claws instead of his fists, and run at greater speeds on all fours, making him more like a beast. Very few of his attacks remain the same, such as the Rasengan, while the others become powerful slashes and explosions. Kyūbi Naruto is one of the many Final Forms in the game, which means he is a completely different character who can wander around with more powerful attacks and that is completely playable on the Final Form Brawl.

Trivia
