Great Aether is Ike's Final Smash in Super Smash Bros. Global Apocalypse. 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) seven times with his sword aflame, kicks them twice, slashes them four more times, and knocks them downward with a powerful finishing blow. The attack does 52%-62% damage. The attack is mostly for damage, rather than knockback.
