Great Aether is Ike's Final Smash. It was described by the DOJO!! as a more powerful version of his Aether. Ike becomes invincible and swings his sword in front of him and anybody who he hits is sent upward. He then leaps into the air, slashes the character(s) fifteen times with his sword aflame, and knocks them downward with a powerful finishing blow, similar to Link's Triforce Slash. Upon impact with the ground, a large explosion knocks any character that happens to be too close.
