Dark Aura

Dark Aura is one of Riku's abilities. They come in two different ways. His first Dark Aura is teleporting around the battle field with his weapon in front of him and ending by landing on the ground with a hard slam that creates a shockwave. His second Dark Aura is shooting a ball of darkness at his opponents.

Trivia

 * The second Dark Aura was previously known as Dark Firaga.
