Androids are artificial beings made to resemble humans. Though they contain organic parts, they are not considered to be cyborgs as androids normally lack free will as well as any memory of who they used to be (if anyone). It is customary for androids to have gray noses to distinguish them from actual humans, though not everyone follows this custom when making androids, especially if they want to fool others into believing the android is an actual human.
Androids tend to have better problem solving capacity than any but the most advanced robots, and they also have a modicum of their own personality. Despite this, most of an android's personality is controlled through their robotic half, and androids can be totally controlled through their programming. The ethics of this are mostly ignored by everyone who makes and uses androids, especially because the parts of the majority of androids are sourced from criminals sentenced to death, people who donate their bodies to science, or cloned.
Most people do not have the expertise to grant an android free will due to the complexity of their programming. Thus, androids with free will are extremely rare, and have no rights in Navroya or anywhere on Acetate because they are still considered property.
