Chaos Wave(ケイオスウェイヴ, Keiosu Weivu?), also known as Chaos Wing or Chaotic Wave, is a recurring ability in the series. It is one of the trademark attacks of Maduin, which inflicts non-elemental damage to all enemies.
Chaotic Wave is the summon attack of the Maduin signet. It can only be used by Wrieg and costs 3 bars from the Summon Gauge to perform. The attack deals heavy light-elemental damage to all enemies.
Chaos Wave is the final HP Attack learned by Terra Branford, unlocking this ability at level 10. This ability unleashes a purple wave of energy around her, damaging opponents that it hits. Although Terra could never use the move herself in Final Fantasy VI or the original Dissidia games, this ability is a reference to her father, Maduin.
