I am making this post to tell everyone who is interested Naruto's forbidden jutsu, because when I was searching on the internet not many seemed to know what Naruto's forbidden jutsu was. Naruto's forbidden jutsu is called, "Fuuton - Rasen Shuriken."

Fuuton - Rasen Shuriken: Its a jutsu that Naruto creates. Its classed as an S-ranked forbidden jutsu because of the damage it does to Naruto's arm. Still, it's damage is far greater than any other jutsu since it rips the opponent to shreds. Naruto overcomes the side effects of the attack after mastering Sage Mode.
