The last greatest human coalition's most elite military unit comprises a stock of biomechanical radioactive psi-mutant God Warriors. These warriors are incredibly dangerous without a handler, and can only be controlled by a close bond with another biological being (who the warrior must recognize as a mate). Mortality rates among human handlers are high, on account of the extreme danger of being in close proximity to God Warriors in combat, their radioactive emissions, and their volatile mental influence on organic minds. So bioroids fulfill this duty in the humans' stead, acting as replaceable proxies between the orders of the human commanders and the alien minds of the warriors themselves. In addition, the peculiarities of a warrior's psionic quirks are impossible to reproduce via direct cloning, exterior wombs, or artificial insemination. So specially-tailored bioroids (often a warrior's own handler) must carry the children of warriors to term.
