Aether

Aether is Ike's up special move, based upon the skill obtainable in Fire Emblem: Path of Radiance, Fire Emblem: Radiant Dawn, and Fire Emblem Awakening. When used, Ike throws his sword up into the air, damaging any nearby enemies and knocking them into the air, then jumps up, flips and slams back toward the ground.

Ike's first custom special variant for this move in Super Smash Bros. for Nintendo 3DS / Wii U is Aether Drive, during which Ike throws his sword diagonally into the air and slams back down; the move gives more horizontal distance but not as much vertical distance. The second variant is Aether Wave, which creates a shockwave when landing that extends the range of the attack but does not deal as much damage.

Great Aether, Ike's Final Smash, is a more powerful version of this move.
