Aether

Aether is Ike's up special move since his debut as a fighter in Super Smash Bros. Brawl. It originates as an obtainable skill from the Fire Emblem series.

Upon using Aether, 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 also gains super armor while throwing his sword, but it only lasts until he jumps, and can be interrupted if Ike gets grabbed. The move offers very little horizontal distance, which can be a hindrance to Ike if he's not below a ledge.

In Super Smash Bros. for Nintendo 3DS / Wii U, Aether's first custom variant is Aether Drive, where Ike throws his sword diagonally into the air, and slams back down. The move offers better horizontal distance, which helps Ike's recovery, but at the same time, the move's vertical distance is shorter than that of the default Aether. 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.
