[@Thecrash20][@Lmpkio] Sounds better. Though I'm slightly curious if the Bio-Blaster "ammo" could be used to eat tiny holes in the hull of a ship, given they can eat through metal. Kind of wondering how it eats through metal given that different metals have stronger or weaker molecular bonds. I would assume it is through chemical reactions to weaken said bonds that the parasites then are able to break by eating. 

Given their tiny size it would require a fairly regular stream to eat away at things like metal armor because each would not be able to carry that much caustic chemicals to quickly eat a hole though. I see this working sort of like an acid gun except instead of firing a liquid it fires the parasites as payloads for the chemicals. Obviously softer materials would be quicker and easier to get through. If this is a fair representation of the Bio-Blaster then I am okay with this.

[@6slyboy6] To be fair, Harriet has a kind of natural armor that can grow back as part of her biology and she can adapt to some extent. Theoretically she would be the embodiment of a bio-being you describe. But she has no range as far as that's concerned. :P For that she relies on your more traditional sci-fi weaponry.
