Pathogenic Tardigradus are one of the rarest genus of Tardigradus.
These species are like their normal counterparts, but have an extraordinary difference; they are stronger, faster, more resistant (especially to venoms, poisons and toxins) and have venom that can kill a fully grown Crewmate.
they generally can survive in almost any sort of toxin unless it is produced by something that they cant survive in, for example sulfuric acid which can be survived by a few other species of tardigradi, cannot be survived by this sort of species as the source of it is derived from a certain type of acid in which they cannot dwell or survive.
they have better sight and are a bit smaller than other tardigradi.
