Alien Grunt
Footsoldier of the invading army, this alien myrmidon relies on telepathy for coordination with its troops, but is no less dangerous when encountered in isolation. Like many inhabitants of the Portal Dimension, it appears to be a colonial creature, harboring several varieties of organic parasites which complement its destructive nature. Most dangerous are swarms of "thornets," heat-seeking autonomous "insects" which breed in their host's paracoelomic cavity and are only too happy to attack and consume the first thing they see upon release. The gleaming partial body armor at first appeared to be the product of an advanced weapons technology; but closer examination of the occasional moribund specimen has shown it to be a biologically extruded exoskeleton, synthesized from a diet rich in certain xenotic minerals. This suggests that long separation from the Portal Dimension, and a diet deficient in alien ores, might lead to the eventual weakening and demise of the alien troops. It is not, however, recommended that Earth rely on poor nutrition to repel the invaders.
