Ok, recently rewatching certain science-fiction franchises, I can safely come to say that the (written!) sound effects for Dracon beams were inspired by
Independence Day lasers. Listen to it, and you'll SEE that they have a distinctly TSEEEW! TSEEEW! Dracon-like sound to them. Also, shredders sound like thus: TSSAPPP! TSSAPPP! which to me sounds like a phaser. So, ideas? Opinions? Anyone care to shoot my theory down? I believe this makes the most sense because Dracons were essentially modified shredders, with different mechanisms.
Of course, that's only just my opinion.
