Flashbash

The flashbash is a projectile device used commonly by the Interplanetary Police Force and other units as a powerful but ultimately harmless projectile. Its intent is to stun targets, as well as blind them with a large flash of Honouran energy. This makes it an ideal method of crowd control. However, on direct contact, the Honouran explosion can posess great force, enough to hurl someone through the air or break down a locked door.

The Displacement of Nes Garrow
The Pillar Enterprises Attack Squadron uses a flashbash that they had on their hands previously to break through the door at Dargzenn's and get inside to confront Skye, Nes, and Will. Upon hearing Commander Canterwelt yelling for a flashbash, Skye reacts immediately, knowing of the power they possess.

Trivia

 * The effect of a flashbash is very similar to that of a Honouran Sphere when it is thrown onto the ground and broken open.
