The Dronox are a species of bioengineered life forms created by the Grox for combat purposes. Since the Grox themselves are extremely frail and can not survive on a planet with an atmosphere, the Grox create these soldiers to do their fighting. Underneath their armor they resemble a cross between an ape and an amphibian.
They are members of the Conqrix, serving as its troops. The Conqrix castes are as follows, in this order:
- DynaMites (also known simply as Mites), the lowest and much like Unggoy suiciders
- Dronox, the middle caste
- Insectrox Commanders (also known simply as Insectrox), a caste slightly above Dronox
- Dronox Commander, a formidable opponent and highest ranking.
