Leaf Shuriken

Metal attacks the enemy, sending him flying with a strong kick, and then finishes him off in the air using Fūma Shuriken.

Trivia

 * In addition to his normal state, Metal also uses this attack while nervous, causing his leg to get stuck in the Fūma Shuriken, which continues to fly towards the opponent along with it, causing Metal to simply collide violently with his opponent.
