Android

Androids were initially designed on planetoid Ceres in the 2200s by Ceres Corp. Although their influence was limited to Ceres for more than half of the timeline of Android population spread; they have spread to every center of human population by 2390. Some suspect that nearly every human leader is an android. After The Secret War, androids began to be mass-produced by human and android investors, and soon became omnipresent throughout The Solar System.

Physiology
Androids, on the surface, are identical to a human, down to the extent of having sweat pores and precise facial muscle movements of regular humans. When internally examined, they also have red blood and what appears to be a set of human internal organs. Only on closer analysis of the insides of these organs (or the skeletal structure) will reveal its base mechanical and electrical components.

Androids operate on a sophisticated level under an Artificial Intelligence Controller Network, or AICN. The AICN can cross-communicate information between androids, and will continually update them with new information as necessary. The AICN cannot directly control the actions of any android connected to it, but may devote more processing power towards androids with set objectives that require a higher amount of focus than normally required. AICNs mostly serve as behavioral regulators, under which an android can behave like a normal person. When not connected to an AICN, androids go "rogue". This results in the overwhelming majority of androids connected to the controller network to enter a "hibernation-state" that is broken whenever a perceived "threat" enters the general area, in which case they will attack on sight. When androids are in this state, they display low intelligence; and due to the lack of a network, do not have a basis for applying knowledge.

When a controller network is shut-off, it will "fracture itself", and give self-sustaining information and behavioral support data to whichever androids were demanding the most resources at the time of the termination of the network. These select few androids are generally ones which are pre-programmed with skills required to program a new AICN, but may have other objectives. These information packets will expire after certain points of time; which will result in the android going rogue suddenly. Some androids enter a limbo-state before going rogue in which they appear to malfunction and exhibit unpredictable and generally violent behavior, while still retaining their consciousness.

Androids differ from their creators in that, while having far less durability and structural support; can exert far more force than a normal human can. (It is often said androids can hit five times harder than an average person, but can be killed five times easier; but these claims haven't been officially substantiated through science yet.) They also cannot process and apply newly learned information that expires past its short-term memory bank (which is smaller than a human's). The only exception to this is when their AI Controller Network deems information necessary, and updates the new information to all androids connected to it.

Methods of Detection
According to the Android Apprehension Society (AAS); there are a few major ways to determine is someone is an android.

Memory Tests
This can either be done in the form of memory games or bringing up a piece of seemingly irrelevant information that was previously exposed to the target. If they are an android and have not identified the information as particularly important beforehand, they will have no ability to recall said information to any capacity.

X-Ray Scans
X-Ray Scans will show a brightly lit and out of focus human form, instead of a normal X-Ray scan of a human; which displays a skeleton with a faint outline.

DNA Records Comparison
As they are not biological; swabbing for saliva, testing dead skin cells, hair, or blood will yield no match to any records of DNA.

Localized EMP
Although the technology is experimental, using an extremely small-scale one-time-use EMP device on a subject will disable them entirely if they are an android.

Stress Testing
Androids will have a harder time supporting weight with their frame. Stress Testing is sometimes done, albeit inhumanely, through the form of beating. Androids will display visible damage much quicker than a human undergoing beatings normally would.
