Aerospark is a Rank 4 command ability used by Ixion, which deals non-elemental damage to one enemy and removes all beneficial statuses from that enemy. Aerospark is also used as an enemy ability by enemy Ixions in addition to Dark Ixion, which acts similarly to the player version although Dark Ixion's version also removes Auto-Life (which the normal Ixion ability does not do). In addition, it has a power of 22 (16 in the final battle of the game) when used by Ixions and a power of 40 when used by Dark Ixion.
