Space Survival: The colossus wasp does not require any type of gas to remain alive, and can withstand the pressures of zero gravity.
Scale: Starfighter
Background
These enormous insects from the planet Ithull measure more than a kilometer long, with wingspans reaching several hundred meters. They feed on stellar radiation, raw proto-materials, and various creatures that survive in vacuum, especially space slugs. Their carapace can withstand incredible pressures, leading bio-engineers to design starships using dead wasp exoskeletons as foundational structures.
