Those drones there aren’t the ones I’m talking about, but Felix has these flat drones with three panels on the front, used for ricocheting bullets off it, like this.

I think it’s important to mention none of their guns are energy guns, the colored trail is just for style, and if many people fire at once in a scene, you can tell who did what. Syfir can also charge his bullets with Umbral Aether, so there’s that.
