Aura Sphere

Aura Sphere is Lucario's standard special move in Super Smash Bros. Brawl. It is similar to Mewtwo's Shadow Ball attack used in Super Smash Bros. Melee, but differs slightly in effect and appearance. Lucario charges up a ball of energy when the attack button is pressed, and then releases it again if the attack button is pressed again. Lucario can also stop charging at any point by moving to the side, using this as a way of escaping attack while still keeping the Aura charge. Upon fire, the Aura Sphere ball moves straight forward along the stage at random speed. The damage done and the speed of the ball is affected by Lucario's damage percent. Aura Sphere is also used by Kirby after he copies Lucario's powers.
