Deros

Deros (an abbreviation of Detrimental Robots) or abandonderos (portmanteau of abandoned + deros) is an appellation most often used to describe a relict population of Titans/Atlans that inhabit the ruins of abandoned underground cities, characterised by extensive physical deformity and mental disorders caused by chronic exposure to solar disintegrant energy. These being are described as highly belligerent, sadistic agents, responsible for a global conspiracy involving the routine abduction of human beings for use as livestock for sexual and experimental purposes and as a food source.

However, it is worth noting that the term "deros" may apply equally to human beings, as all living creatures on this planet are continuously exposed to disintegrant energy, leaving each of us with the potential to become detrimental robots over time; the abandoned Titans of the underground world have simply been longer and more routinely exposed, thanks to their utilisation of "apparatus full of dis particle accumulations," and show clearer manifestations from this exposure.
