Aether

The beginning of the move, in which Ike throws the sword upwards.

Aether is Ike's Up B attack in Brawl. He first throws his sword in the air. During this time, he can take damage, but cannot flinch. After the sword hits the apex of its trajectory, he jumps up, catches it, and comes hurtling towards the ground. It appears functionally similar to Kirby's Up B move, the Final Cutter. It is unknown whether the trajectory of the sword can be altered or not, ie. "DI".
