A particle beam that leaves only dust in its wake.
—Menu description of the Cloud of Darkness's EX Burst, Dissidia 012 Final Fantasy
Wave Cannon(波動砲 or はどうほう, Hadōhō?), also known as Surge Beam, Surge Cannon, Beam Cannon, Particle Beam, CannonWave Artillery, and FlareWave, is a recurring enemy ability in the series. It typically deals large amounts of damage to the entire party. It is most often associated with the Cloud of Darkness and Omega as their signature attacks.
VWave Cannon, previously known as Beam Cannon, first appears in this game as an attack used by Soul Cannon, which deals damage to the entire party equal to half of each individual character's maximum HP as well as inflicting Sap. The superboss Omega has access to this attack as well, as does Omega Mk.II in the Game Boy Advance remake.
The Cloud of Darkness uses many versions of her Particle Beam attacks during the raid fight against her. Some other powerful Voidsent such as Calofisteri, Scathach, and Diabolos Hollow also possess certain forms of Particle Beam.
The primal Zurvan uses Wave Cannon as one of his attacks, which he fires from outside the edge of the arena in a straight-line.
During a cinematic cutscene at the end of 3.55 The Far Edge of Fate, Omega uses Wave Cannon in a beam struggle against Shinryu'sProtostar attack.
One of the Cloud of Darkness's cards can use Ultra Particle Beam. For the discard of another Cloud of Darkness card and the payment of any amount of Water CP the player chooses, the ability decreases the power of all the opponent's Forwards by 1000 times the amount of CP paid, until the end of the turn. The same card also has a less powerful ability similar to Ultra Particle Beam, Dulling the Cloud of Darkness and paying any amount of CP to decrease the power of a single forward by 1000 times the CP paid.
In Final Fantasy VIII, Trauma uses an attack known as Mega Pulse Cannon, while the Dromas uses an attack known as Mini Pulse Cannon. Both in the Japanese versions are known as Surge Cannons, linking them to the Wave Cannon ability.
