Subject-SD

== Special Containment Procedures (Iteration 4 - Current iteration): ==
Subject-SD is to be contained within a reinforced humanoid containment chamber at Xiowa Facility-██ ██km █████ ██ ██ ███████ ████, Haide. The chamber is to be equipped with motion sensors, pressure plates, and electromagnetic field disruptors to detect and deter any attempted escape by Subject-SD. Surveillance cameras are to be installed within the chamber to monitor the entity's activities continuously.
Subject-SD is required to be fitted with a specialized containment suit composed of reinforced materials designed to inhibit its anomalous abilities. The suit incorporates electromagnetic field generators and energy-dampening technology to neutralize Subject-SD's phasing capabilities and limit its speed to manageable levels. The containment suit is to be maintained and inspected regularly for any signs of wear or malfunction.
Access to Subject-SD's containment chamber is restricted to personnel with clearance approved by both the Haidean President and the Commander-in-Chief of the AFHR. Any experimentation or interaction with Subject-SD must be approved by these two parties and conducted under controlled conditions with a maximum allowed time of 15 minutes.
In the event of a breach or attempted escape by Subject-SD, joint Haidean and Chemgotan contingent █████ ███████ ██████ are to be immediately deployed to recontain the entity using non-lethal force. Containment breach drills are to be conducted regularly to ensure personnel readiness and response effectiveness in the event of an emergency.
In the event of Subject-SD breaching containment and evading initial recontainment efforts, the Haidean Government will implement Contingency Plan Sigma-Delta: the Speed-Demon Incident Response Protocol. This protocol is designed to mobilize specialized containment teams and deploy advanced countermeasures to apprehend Subject-SD and mitigate the threat it poses to civilian populations.
# Immediate Notification: Facility personnel are to immediately notify both Haidean and Chemgotan governments, as well as █████ ███████ ██████ Command of Subject-SD's breach and provide relevant intelligence regarding the entity's last known location and potential targets.
# Activation of Specialized Containment Teams: █████ ███████ ██████ will be placed on high alert and deployed to the area of Subject-SD's last known whereabouts. Additionally, specialized containment teams equipped with advanced tracking equipment and anomalous detection technology will be mobilized to assist in locating and apprehending Subject-SD.
# Deployment of █████████ Countermeasures: If initial recontainment efforts fail, the AFHR will deploy countermeasures specifically designed to neutralize Subject-SD's abilities and facilitate its recapture. This may include the activation of █████████ ███████ ████████ ███ ██████████ ██ ███████████ ███████ ██ ███ ███ ██ ████████ ██████ ██████ to temporarily immobilize the entity.
# Coordination with Local Authorities: Dispatched operatives will coordinate with local law enforcement agencies and government authorities to establish containment perimeters and disseminate information regarding Subject-SD's anomalous nature and potential threat to public safety. Civilians will be evacuated from affected areas, and containment teams will be authorized to utilize non-lethal force as necessary to subdue Subject-SD. Note: After recontainment is succesful, all higher-ups of local authorities who are aware of Subject-SD's abilities are to be taken to Facility █████████ ███ and summarily ████████. ███ ██████ will be ██████ as to ████ ███ ████████.
# Containment and Neutralization: Once Subject-SD has been located, containment teams will utilize specialized containment equipment and █████████ ███████████████ to neutralize the entity and facilitate its recapture. This may involve the use of containment chambers equipped with ██████████ ███████████████ █████ ███████████ ████████████████ ██████████, and GPS tracking devices to immobilize and contain Subject-SD effectively.
# Debriefing and Analysis: Following the successful recontainment of Subject-SD, Foundation personnel will conduct debriefings and post-incident analysis to evaluate the effectiveness of Contingency Plan Contingency Plan Sigma-Delta and identify areas for improvement. Lessons learned from the incident will be incorporated into future containment protocols and response strategies to enhance readiness and mitigate the risk of similar incidents occurring in the future.
=== Previous Containment Procedures ===
Previous Containment Procedures (Iteration 1): 
Subject-SD is to be contained within a standard humanoid containment cell at Xiowa Facility-██. The cell is to be equipped with reinforced walls and a reinforced steel door secured by electronic locks. Surveillance cameras are to be installed within the cell to monitor Subject-SD's activities continuously.
During routine surveillance, Subject-SD was observed breaching containment by phasing through the reinforced walls of its containment cell. Security personnel attempted to apprehend the entity, but Subject-SD incapacitated them with blinding bursts of █████ before vanishing into the facility's ventilation system. As a result of this breach, ███ casualties were reported, including █ personnel and ██ civilian bystanders. Subject-SD remained at large for █ days, leaving behind cryptic messages etched onto the walls of its former containment cell before its eventual recapture.
Previous Containment Procedures (Iteration 2):
Subject-SD is to be contained within a specialized containment chamber outfitted with electromagnetic field disruptors and soundproofing measures at Xiowa Facility-██. The chamber is to be equipped with motion sensors and pressure plates to detect any unauthorized movement. Subject-SD is to be provided with a standard humanoid containment suit to mitigate its anomalous abilities.
Subject-SD exploited a flaw in the containment chamber's ███████████████ █████ ██████████, overriding their functions and disabling surveillance equipment within the chamber. With its anomalous abilities unhindered, Subject-SD incapacitated security personnel and breached containment, leaving behind only eerie whispers and unsettling symbols etched onto the walls. The entity then proceeded to vanish into the surrounding wilderness, where it remained undetected for █ weeks. During this time, reports of mysterious disappearances and unexplained phenomena surfaced in the nearby town, resulting in ██ casualties before Subject-SD was eventually located and recontained.
Previous Containment Procedures (Iteration 3):
Subject-SD is to be contained within a reinforced containment chamber outfitted with a Faraday cage and ███████████████ █████ ██████████ at Xiowa Facility-██. The chamber is to be sealed with reinforced blast doors and monitored by armed security personnel at all times. Subject-SD is to be provided with a specialized containment suit equipped with ████████████████ ██████████ and GPS tracking devices.
Subject-SD manipulated the ███████████████ █████ ██████████ within its containment chamber, causing a temporary power outage that disabled security systems and breached containment. Taking advantage of this blunder, Subject-SD incapacitated security personnel and fled the facility, leaving behind cryptic messages scrawled in blood on the walls of its chamber. The entity then embarked on a spree of predatory attacks, targeting unsuspecting homes in nearby urban areas. ██ casualties were reported as Subject-SD eluded capture for █ weeks, before being cornered and recaptured by Chemgotan operatives.

Subject-SD is the name given to a highly enigmatic and dangerous humanoid entity by the Haidean Republic, first documented in the late 21st century, then captured by the AFHR in 2107. This anomaly exhibits extraordinary speed and several other supernatural abilities that make it a subject of intense study and concern. Despite having a human appearance, Subject-SD's capabilities far exceed those of any known human or animal. Its sightings have been documented over most of Haide, Chemgota, Nokyta, Korea and China, often making people disappear in it's wake.
Standing at approximately 1.77 (5'8) meters in height, Subject-SD possesses a very lean and skinny build, with features reminiscent of an adult male with very low body fat. The anomaly looks to be that of a man in his late teens, with Indonesian ethnic traits. Its skin exhibits a pale luminescence, emitting a soft, ethereal glow that slightly illuminates its surroundings in darkness. This eerie glow is a hallmark of Subject-SD and serves as a visual indicator of its anomalous nature. However, Subject-SD typically masks it's glowing skin by wearing a set of civilian clothes, presumably to blend in with the crowd. It's main clothing includes a black beanie, grey Adidas jacket and a beige pair of cargo pants, though this can vary depending on the climate and region Subject-SD is in.
Beyond its appearance, Subject-SD possesses a myriad of anomalous abilities that set it apart from both humans and conventional technologies. The primary and most prominently displayed ability of Subject-SD is its extraordinary speed. Subject-SD has been observed moving at velocities far surpassing the capabilities of any known terrestrial organism, with recorded speeds exceeding Mach 3 (approximately 3,700 km/h) on average. Its movements are so rapid that they appear as little more than a blur to the naked eye, making visual tracking and apprehension exceedingly difficult. This incredible speed allows Subject-SD to traverse vast distances in mere moments, rendering traditional methods of containment and pursuit ineffective.
In addition to its unparalleled velocity, Subject-SD possesses the ability to phase through solid objects with apparent ease. This phasing ability extends to both organic and inorganic matter, allowing it to pass through obstacles and barriers without causing damage to itself or the objects it interacts with. Whether traversing through walls, vehicles, or even living organisms, Subject-SD demonstrates complete control over its molecular structure, granting it unparalleled freedom of movement. This ability not only facilitates it's evasion of capture but also enables it to navigate complex environments with ease, making Haidean containment efforts all the more challenging.
Furthermore, Subject-SD exhibits a range of other abilities that further enhance its capabilities. Among these is its heightened reflexes, which allows it to react to stimuli with inhuman speed and precision. Whether evading incoming threats or launching counterattacks, Subject-SD reflexes enable it to anticipate and neutralize it's targets with ease. Additionally, Subject-SD has demonstrated proficiency in energy manipulation, with the ability to control kinetic and potential energy within its vicinity. This manipulation extends to both offensive and defensive applications, allowing it to generate concussive blasts, create protective barriers, and enhance its physical capabilities in needed circumstances.
Moreover, Subject-SD displays rapid regenerative capabilities, enabling it to heal from injuries at an accelerated rate. Even wounds otherwise fatal that have been inflicted upon Subject-SD typically heal within moments, rendering all conventional methods of incapacitation ineffective. This remarkable regenerative ability not only prolongs Subject-SD survivability but also allows it to continue its activities mostly uninterrupted, posing a significant threat to World Governments and civilian populations alike. Additionally, Subject-SD can selectively render parts of its body intangible, granting it partial or complete immunity to physical harm. By phasing through solid matter or altering its molecular structure, Subject-SD can evade attacks and navigate hazardous environments with relative ease, further complicating re-containment efforts.
=== Primary activities ===
Subject-SD's activities predominantly center around home invasions and the subsequent disappearance of occupants. Subject-SD exhibits a particular preference for infiltrating residential dwellings under specific conditions, resulting in its appearance and subsequent anomalous activity within these homes over others. However Subject-SD has been shown to invade homes that do not meet these requirements, meaning it is able to conduct it's activities almost anywhere it pleases.
The conditions conducive to attracting Subject-SD to a particular residence are multifaceted and often involve anywhere from one to a combination of these factors. These conditions are as follows:
* Extreme Weather Conditions: Subject-SD is more likely to manifest during periods of extreme weather, such as blizzards, thunderstorms, or dense fog.
* Household Festivities: Subject-SD is known to target homes during periods of celebration or festivity, such as holidays or family gatherings.
* Family Conflict or Discontent: Homes characterized by ongoing family conflict, unresolved grievances, or discontent among occupants are more likely to attract the attention of Subject-SD.
* Presence of three or more Statues: Subject-SD exhibits a particular interest in homes inhabited by three or more statues, the reasoning is unclear.
* Historical Tragedy or Misfortune: Properties with a history of tragic events, such as accidents, suicides, or unresolved mysteries, are more prone to infiltration by SCP-XXXX. The residual emotional energy lingering within these homes serves as a beacon for the Velocity Wraith's manifestation, drawing it to these locations with greater frequency.
* Lack of Religious Iconography: The absence of any religious iconography or protective symbols within a home may also increase its susceptibility to Subject-SD's intrusion. Homes devoid of religious artifacts or spiritual protection are more vulnerable to the entity's influence, as they lack the supposed deterrent effect provided by such symbols.
=== Event ===
Subject-SD's actions upon infiltrating homes unfold in distinct phases, each contributing to its predatory modus operandi within the affected residence. These phases encompass a sequence of eerie events that gradually escalate in intensity, leaving the occupants vulnerable to it's intent:
# Phase One:
#* The initial phase begins with the Velocity Wraith's silent infiltration of the home, utilizing its phasing abilities to slip through walls or locked doors undetected.
#* Occupants may experience subtle disturbances in their surroundings, such as flickering lights, unexplained drafts, or inexplicable shadows flitting across the walls.
#* Subject-SD's presence is felt as a faint, eerie sensation in the air, inducing a sense of foreboding and unease among the occupants.
#* Subject-SD will move about the house at will when nobody is home or when everyone is asleep.
# Phase Two:
#* With the occupants sufficiently destabilized, Subject-SD launches sudden and ruthless attacks on its victims, utilizing its extraordinary speed and other abilities to strike with swift and brutal efficiency.
#* Victims may experience ████████████ ███████ ██ █████ and high-speed movements as Subject-SD closes in for the kill, leaving them incapacitated or paralyzed with fear.
#* Subject-SD seem to target the eldest member of the household first, killing them in a ritualistic fashion, in which it will █████ ███ █████ ████████ █████ ████ █ ████ ███████ ███ ██████ ████ ██████ ███ █████ ██ █ ███████.
# Phase Three
#* Following its the termination of it's first victim, Subject-SD will proceed to kill half the population of the household, in no particular order, and will abduct half of the remaining survivors from the home, typically the most athletic out of the remaining.
#* Victims of Subject-SD's abductions are often never seen or heard from again.
