A recent creation by Elysian military science, the S17 represents the revisitation of advancement on genetic weapons. It is a weapon above all else - and due to a number of its standard features (not least of all being a hive mind) is probably unsuitable for use as a player character.
The S17 is significantly less humanoid in appearance than past Seraph models, maintaining only a vague semblance of such appearance. It is, much like its predecessor, liquid in form, able to absorb and regenerate vast amounts of physical damage while remaining operational. The liquid nature of its body also allows for another capability drawn from (and improved from) past models - the ability to shift its physical appearance to represent that of an individual for whom a DNA sample is available. They can also assume a state of utter transparency, and lack any scent - making them useful in stealth, though this is far more commonly used for ambush.
The S17 has psionic capabilities to rival those of the most advanced Nekovalkyrja, though the focus is on other areas. Specifically, the S17s are of exceptional talent in dominating the minds of other creatures. Due to the hive mind nature, the more S17s present on a scene, the more overbearing the mental dominance they can exude. Because they are mass-produced, this can make them an incredibly potent enemy. Beyond mind control, the S17 posesses respectable capacity for psychokinetics, and the thoughts and visions are constantly shared between all S17s within a 10km radius - resulting in coordination that is extremely difficult to keep up with. Telepathy can be projected to a range of 50 times that distance, should some need arise.
In the area of physical capability, the S17 is no stronger than an average Human - often weaker, in fact. They have no need for strength, and rarely if ever engage in physical combat. When forced into such engagements, the genetic build of their bodies can be altered to become highly corrosive. This is a last resort, and causes the S17 to destroy itself after a period of 2 Standard hours.
S17 Seraph appear as vaguely humanoid creatures of gelatinous composition. They look nearly transparent, though they are opaque when not in active stealth. The color of the 'flesh' is pale blue-grey in its natural state, but can assume virtually any pigment that a DNA sample is available for. They have no mouths, and no visible eyes or ears. Each 'hand' is four-fingered, lacking thumbs, prints, or any discernable unique pattern.
