Undying

>General Knowledge
Entity 16, scientifically referred to as “Undying,” is a unique entity with human-like features and appearance; there are no ways of "dispatching" these entities as of now, thus their name. They are incredibly dangerous, and any hostile encounters with them have always resulted in the death of the victim.
While seemingly intelligent, being capable of communicating in various human languages, they are seemingly always in an aggravated state, beating up anything it could possibly latch on. They have incredible speeds, and it should be noted that if the victim is ill-prepared, chances are that they will die or be severely injured.
They are occasionally spotted alone, roaming around different levels—often hunting or stalking its prey for food. While one may attempt to escape, and rightfully so, outrunning them is impossible; albeit, it is quite possible to outmaneuver them as it appears that they are unable to climb as well as swim. It is important to aim for their head, for instance, using a crowbar or metal pipe to cudgel their head. It's their weakest point, but they will only be immobilized for several minutes before being able to resume to their typical functionality.
>Appearance
As mentioned before, Entity 16 has human-like characteristics, on some occasions completely indistinguishable to a human. Though, their body parts are sometimes deformed, possessing rotten skin and half-developed, or even completely missing Their body parts can be easily broken off, but they are still very effective at causing serious injuries to those that happen to encounter one. Internally, many vital organs are replaced a singular, blackened organ named a "Parasite."
Further autopsy revealed that their brains are very similar to, functioning such as humans, and, in some cases, completely identical. They also possess the ability to seemingly "regrow" their body parts, though, this ability is rarely observed.
Their faces are disfigured, and most of the time, terrifying—as described by several survivors. Individuals who come into contact with Entity 16 often experience significant psychological distress, such as PTSD and other mental health concerns. Due to the severity of their experiences, many require long-term treatment to cope with the traumatic effects.
>Relationships & Abilities
Unlike other entities, Entity 16 sometimes holds a companionship with Entity 8; they often signal each other and coordinate their attacks to attack their prey. While Undyings are incredibly fast and agile, it is unable to attack for long periods of time; due to their constant desire for blood, they need to corporate with other entities—namely hounds to perform this task efficiently.
As previously mentioned, the entity can communicate using various human languages; more commonly English and Spanish. They will often blurt random words or unintelligible phrases out loud or attempt to say a sentence even though they are inaudible. It should be noted that they rarely perform this and one should not attempt to communicate, as this will simply do nothing if you are facing them head-on, or will alert them of your position.
At times, a female Entity 16 partakes in the act of mating with males to conceive an offspring, or "Undead," the scientifically recognized term for a juvenile Undying. The resultant progeny, specifically designated as Entity 16.1, is inclined to follow the parent of their respective gender. Unlike their fully grown counterpart, Entity 16.1 exhibits passivity and fragility, unable to secure food sources, and reliant on their progenitor for sustenance. Nevertheless, the male or female parent exerts protection against any perceived danger or menace to their offspring. Following a span of several months, Entity 16.1 develops into Entity 16, equipped and capable of voyaging independently.
