The Cackler

Class: Keter

Special Containment Procedures:

REVISION 1-A

No interaction with [The Cackler] is allowed at any time. All interactions with [The Cackler] must be approved by at least a 3/4s majority vote from O5-Command, and should only extend to test situations. All staff (Research, Security, Class D, etc.) are required to undergo a psychological evaluation before entering within [The Cackler]’s range of influence so as to reduce the chances of all Class (1-3)A Events by [The Cackler]. All test situations must be conducted through the use of at least two Class D subjects, with one of the subjects meeting at least one of the psychological factors indicated by Dr. [DATA EXPUNGED]’s research into [The Cackler]’s preferred subject-pool. During test situations, all non-Class D staff are to remain approximately 5 meters outside [The Cackler]’s range of influence until testing is completed.

[The Cackler] is kept within a sealed containment cell with the interior of [The Cackler]'s cell padded with aluminum plating approximately 32 in. thick. [The Cackler] should be continuously monitored for any signs of agitation or behavior leading up to a Stage (1-3)A Event induced by [The Cackler]. Any movement or non-normal activity by [The Cackler] should be reported to Dr. [DATA EXPUNGED] immediately and full site lock-down initiated. Lock-down shall be maintained until a “situation clear” dispatch is issued by Site Command. Any “Bleed Effects” following a Stage 3A Event are to be reported to Site Security immediately, with cleanup and repairs to the affected areas implemented and completed before a “situation normal” dispatch is issued. All reported “Bleed Effects” are to be destroyed within 2-8 hours after their discovery. Any objects, items, and/or personnel lost to [The Cackler] are to be deemed missing/KIA, with any survivors of an attack by [The Cackler] interviewed and anesthetized.

Note: As exhibited during Incident 44A, [The Cackler] doesn’t have a “preferred subject pool” indicated by the late Dr. [DATA EXPUNGED], any observed “docile states” and/or increased compliance by [The Cackler] is to be deemed a manipulation tactic proceeding an aggressive action and containment breach attempt, and should be treated as such.

NOTE: PROCEDURE AND TESTS DISCONTINUED DUE TO INCIDENT 44A.

REVISION 2-A

No interaction with [The Cackler] is allowed at any time. All interactions with [The Cackler] must be approved by at least a 3/4s majority vote from O5-Command, and should only extend to induced communication with [The Cackler]. Any such interactions must be undertaken in AR-II maximum security sites, after a general non-essential staff evacuation. The amount of time spent within [The Cackler]’s range of influence should not exceed more than approximately 13 hours, which applies to all staff (Research, Security, Class D, etc.). Any staff caught extending the maximum allotted time will be forcefully removed and their security clearance revoked for approximately 4 weeks. [The Cackler] should be continuously monitored for any signs of agitation or beginning symptoms of a Stage (1-3)A Event. Any behavior deviating from [The Cackler]’s normal behavior and movement is to be reported to site command immediately and possible evacuation alert given to all staff. Any observed “docile states” and/or increased compliance by [The Cackler] is to be deemed a manipulation tactic preceding an aggressive action and containment breach attempt, and should be treated as such. Any individuals experiencing or having experienced a Stage 1A Event are to report it to site head immediately followed by an extensive psychological examination, and are to be transferred from Site [REDECTED].
[The Cackler] is kept within a sealed containment cell with concrete walls measuring approximately 3 meters thick, and padded with Aluminum plating approximately 32 in. thick. Cell interior and exterior are to be coated in approximately 8% [Data Expunged] solution in order to reduce possible damage in the event of a Stage 3A Event.

In the event of a Stage 2 or 3A Event, full site lock-down initiated effective immediately, with Task Force Nine-Tailed Fox on standby in the event of [The Cackler] breaching the premises. Site lock-down is to be maintained until visual confirmation of Stage 1A Event’s conclusion followed by [The Cackler]’s return to normal behavior. Once visual confirmation is confirmed and a “situation clear” issued by Site Command, Task Force Nine-Tailed Fox is to be dispatched to re-contain [The Cackler]. Any “Bleed Effects” observed by staff after a Stage 3A Event is to be reported to Site Security immediately, with cleanup and repairs to the affected areas implemented and completed before a “situation normal” dispatch is issued. All reported “Bleed Effects” are to be destroyed within 2-8 hours after their discovery. Any objects, items, and/or personnel lost to [The Cackler] are to be deemed missing/KIA, with any survivors of an attack by [The Cackler] interviewed and anesthetized. All items reported missing from a previous Stage 3A Event, or cataloged items are to be cataloged in the event that they are discovered in the aftermath of any future Stage3A Events, at which point the items should be documented then destroyed. Any unidentifiable items discovered after a Stage3A Event should also be documented and then destroyed.

Description: [The Cackler] is a pale humanoid entity standing approximately 2.4 meters in height. [The Cackler] appears to be covered in a large, dark trench coat, and detailed examination of its material has revealed that the trench coat is composed of a variety of fabrics of different centuries dating back to the early 16th century. Microscopic examination of the material revealed the fabric to contain small organic particles similar to [REDACTED]. Preliminary examination during its initial capture has revealed [The Cackler] to be nearly devoid of any facial features with the only discernable facial features being long white hair and a relatively large mouth with the teeth exposed in a permanent smile. In spite of being eyeless, The Cackler is capable of maneuvering around in its environment via unknown means. Preliminary examination of [The Cackler] also revealed that its extremities to be approximately 5-9% longer in comparison to human proportions.

[The Cackler] is extremely dangerous and unpredictable, responsible for multiple successful and unsuccessful containment breaches, resulting in the deaths of [REDACTED] personnel including former site head Dr. [REDACTED]. [The Cackler]’s first containment breach attempts involved extended physical assault upon its cell walls which resulted in several successful containment breaches and forced staff to upgrade [The Cackler]’s containment chambers. During these successful and unsuccessful containment breaches, [The Cackler] has exhibited strength, endurance, and agility that greatly exceeds that of a normal human being. [The Cackler] is also shown to be capable of scaling any vertical surface, hanging upside down for hours at a time.
The most dangerous ability of [The Cackler] is its ability to manipulate and warp reality within a 10-meter radius of itself designated as [The Cackler]'s "Range of Influence", the severity of such reality warping are classified under Stage 1A to Stage 3A Events, with Stage 3A Events being the most severe cases. All stages occur once a subject is within [The Cackler]'s range of influence. Each Stage 1A-3A Events are categorized and described under the following conditions:

• Stage 1A Event: The least severe case of reality warping by [The Cackler], Stage 1A Events involve manipulation/warping of reality in the appearance of hallucinations. The appearance and nature of these hallucinogenic apparitions varies greatly with each individual affected by the event, however all Stage 1A Events induced by [The Cackler] are primarily used as a means to psychologically manipulate the individual, either by warping its appearance in order to resemble someone close to the affected individual, or warping the appearance of objects near the targeted individual. During [The Cackler]’s escape from Site [REDACTED], which lasted for a period of 2 weeks, [The Cackler] was later captured after it was discovered after a Stage 1A Event in which it attempted to take on the appearance of an individual trusted by its potential victim. Stage 1A Events are not known to induce any "Bleed Effects".

• Stage 2A Event:

• Stage 3A Event:

Discovery and Containment: [The Cackler]’s existence and activity were first detected in 1935 during a preliminary homicide investigation in [REDACTED], Maryland closely resembling activity first reported occurring at an alternate location in 1921. All incoming information gathered by local authorities and resulting media coverage of [The Cackler]’s activities were subsequently falsified as SCP staff continued to monitor [The Cackler] up to its subsequent capture and containment. Observations of by SCP staff noted [The Cackler]’s activity interspersed between the two different locations until its subsequent capture in 1942. In 1938, [The Cackler]’s secondary location began displaying signs of worsening condition due to various unchecked “Bleed Effects” characteristic of multiple Stage 3A Events were discovered at various points within the location. As a result, SCP staff was forced to destroy the location in an effort to neutralize the exhibited “Bleed Effects” which was effectively falsified to all media outlets. At the same time, all case files relating to [The Cackler] were confiscated by SCP operatives. [The Cackler] would kill one more individual at the secondary location after its destruction before it began hunting exclusively at the site of its eventual capture. SCP staff would continue to monitor [The Cackler]’s activity from 1939 to its capture in 1942 (See Addendum [The Cackler]-01).
At the start of 1941, [The Cackler]’s activities grew increasingly violent and difficult to suppress, as a result, SCP staff came to the decision that [The Cackler] should be permanently contained within Site [REDACTED] for further observation and research. The decision to secure [The Cackler] was headed by the late Dr. [REDACTED] who would oversee all observation and research of [The Cackler] until his death during Stage 3A Event-07 (See Addendum [The Cackler]-03 for more details) .
