Viper uses AirForce.
|Description||Make huge blades of thin air and hurl them at foes.|
With his weapon, Viper slashes at the air and forms arcs of yellow energy in a bird- or aviation vehicle-pattern. Then, he directs the construct at an enemy, where it collides painfully.
AirForce seems to be a pun of the fact that Viper controls air and uses it as a force or weapon. Additionally, the Air force is a military branch which specialized in aviation warfare and training. Since Viper, himself, is an Acacia Dragoon, this name lends purpose to that as well.
