And Penny's lasers generally didn't pierce things, except when she combined literally all of them into one giant cannon, so lasers in the RWBYverse don't necessarily have to pierce straight through something in order to count as lasers. Penny's lasers........don't strike me as Dust though. Between the way they worked and their appearance, I'm more inclined to believe it's some "special weapon" of Penny's, or maybe some special Aura Technique of the same "Tree" as Blade Beams (Using Aura to create a projectile).

It might be something that would be too tiresome for a person to use normally, but since she's a Robot she doesn't have such limitation.

Also, since you say "except"....did Penny ever shoot lasers without using that "Giant Laser Cannon" (Which is not giant, nor a cannon)?
