Shuriken

Shuriken (手裏剣) literally meaning "Sword hidden in the hand", was Naruto's previous side special move prior to v0.8a version of the SSF2 Demo in Super Smash Flash 2, replaced with Shadow Clone Toss.

They are sharpened,four-pronged metal stars, useful for throwing. Although small, they can be used to distract, pin down enemy shinobi, or if accurate enough, can be deadly. They have an open circle in the centre, used for grabbing with a finger, to avoid cutting oneself, or to put thread through. The circle is also beneficial to the weapons overall aerodynamics, ensuring more accurate trajectories.

Naruto throws a Shuriken straight forward. The projectile's range extends to more than the entire length of Final Destination. The projectile deals decent damage (10% to be exact) and horizontal knockback but little vertical knockback, which can be used to lock a character at higher percentages, but has terrible priority. The only character that has shown how to dodge it with out pressing the shield button is Kirby. Kirby can just duck down and dodge it since his body is compact. As of v0.8, Shuriken became a part Naruto's back throw,in v0.9,the shuriken's color is black.
