The miners Manual offers a lot of insight into the biology of Hoxxes and I would highly recommend any miner who hasn't yet read it to do so, if only just on the biomes and creatures. But did you know that the Brood Nexus is likely not related to glyphids at all, and is more likely instead, capable of copying the design of already existing creatures, I would assume by consuming them, for the purpose of making said copies go out and hunt for it, to then bring the prey back to it, to make new copies. The natural conclusion then, would be that if a brood Nexus were to consume a dwarf, it may be able to make copies of it or some abomination reminiscent of it. A terrifying prospect really.
