The Graxan Heavy is the Graxan Empire's meatshield on the battlefield. Only the largest, strongest and quite often dumbest of the Graxans are up to the task.

Graxans are fat, toad-like amphibians. They have a thick,sagging skin that is usually a shade of green or brown and is sometimes blotched or spotted with bright yellow, orange or red. Unlike toads, their eyes are proportionately tiny and are diagonally-slit. They do not have protruding noses, just two slits between their eyes. They more than make up for a lack of eyes or nose, with large mouths that open like drawbridges when they talk and contain many shark-like teeth. Oh, and they belch fire. Instinct: to scavenge

The grey goo is a floating mass of self-replicating nanobots. Its appearance is more like mercury than its namesake suggests and only appears as a goo-like substance to those without microscopic vision. Drawn forever towards the strongest gravitational pull, the nanobots move through space and consume all matter that they come into contact with. The grey goo only starts off small; it grows larger or more numerous the more matter it consumes. Instinct: to replicate
