These nanites bond at a molecular level, often causing uncontrolled mutations that produce EVOs (Exponentially Variegated Organisms), ranging from destructive, monstrous threats that endanger civilization to sentient, intelligent beings capable of forming societies and pursuing their own agendas. The environmental fallout manifests in altered landscapes, with urban areas scarred by EVO attacks and rural zones harboring hidden mutant enclaves, creating a perpetual state of tension between and the chaotic integration of mutated life. Key locations anchor this lore, including the sprawling headquarters, a fortified, high-tech complex serving as the nerve center for global anti-EVO operations and symbolizing humanity's organized resistance.

Recurring extraterrestrial elements, such as enigmatic ships, introduce mobile, insectoid vessels that function as invading forces or exploratory hubs, expanding the setting beyond to interstellar threats tied to nanite origins. Thematically, Generator Rex delves into self-discovery through the lens of nanite manipulation, where characters navigate the psychological and physical implications of their powers, questioning what it means to reclaim or redefine one's humanity in a mutated existence. Central to this is the anti-hero embodied in Providence's dual policy of curing EVOs via nanite extraction—restoring normalcy—while authorizing lethal neutralization for incurable threats, which probes the of and the moral ambiguity of imposing "cures" on unwilling subjects. emerges as a counterbalance to in this unstable world, with bonds forged in underscoring loyalty's fragility against institutional and personal deceptions.

Rex's enlistment with briefly illustrates this dichotomy, positioning him as a bridge between human enforcers and EVO victims in the ongoing struggle.
