Summary
Item #: SCP-4455

Object Class: Keter

Special Containment Procedures: SCP-4455 is to be contained within a reinforced, airtight, and electromagnetically shielded chamber measuring 20m x 20m x 20m at Site-██. The containment chamber must be equipped with redundant fail-safe mechanisms and a secondary containment area. Access to SCP-4455's chamber is restricted to Level 4 personnel with authorization from the Site Director.

The chamber housing SCP-4455 must be equipped with a Faraday cage, capable of neutralizing all electromagnetic emissions from SCP-4455. The Faraday cage's integrity must be checked regularly, and any breaches must be repaired immediately. No electronic devices are allowed within a 10-meter radius of SCP-4455.

SCP-4455's containment chamber must be under constant surveillance via closed-circuit cameras to monitor any changes in its behaviour or anomalous activity. In the event of a containment breach or any sudden increase in electromagnetic activity, Site security personnel must activate the Faraday cage's fail-safe protocols and implement MTF Kappa-7 ("Grim Wardens") to re-contain SCP-4455.

Under no circumstances should SCP-4455 be activated or tested without prior approval from the Site Director and Ethics Committee review.

Description: SCP-4455, also known as the "Grimace Shake," is an enigmatic, ancient artifact resembling a handheld milkshake mixer with an unsettling design. Its outer shell is composed of an unknown black material that defies analysis, exhibiting properties that resist all attempts at damage or replication.

When SCP-4455 is activated, it emits a combination of an infrasound wave and electromagnetic pulses. The infrasound wave has a range of approximately 50 meters and can pass through most solid barriers. The infrasound emitted by SCP-4455 causes intense feelings of fear, anxiety, and paranoia in individuals exposed to it.

The electromagnetic pulses emitted by SCP-4455 affect all electronic devices within a 100-meter radius, causing them to malfunction and ultimately leading to permanent damage. This includes power outages, data corruption, and the disruption of communication networks.

SCP-4455's most dangerous effect is its ability to influence human minds within its range of effects. When individuals are exposed to SCP-4455's infrasound and electromagnetic waves, they experience a heightened state of emotional distress and agitation. This effect increases with proximity to SCP-4455, leading to cognitive impairment, irrational behaviour, and eventually loss of self-control.

Personnel exposed to SCP-4455 have reported vivid and horrifying hallucinations, commonly described as "nightmarish visions." These hallucinations often involve grotesque and surreal imagery, reflecting the individual's deepest fears and anxieties. Continued exposure to SCP-4455 intensifies these effects, leading to a state of extreme mental and emotional instability.

Additionally, subjects exposed to SCP-4455 become fixated on the object, developing an obsessive desire to protect and defend it. This fixation appears to be involuntary and has been observed even in individuals with no prior knowledge of SCP-4455's anomalous properties.

Prolonged exposure to SCP-4455 results in irreversible psychological damage, with affected individuals succumbing to a state of catatonia or psychosis. In some cases, subjects have displayed self-destructive tendencies and attempted suicide while under the influence of SCP-4455.

Addendum 1: Incident Log 224554-01 On ██/██/████, a containment breach occurred in SCP-4455's chamber when a Level 3 researcher, Dr. ██████, mistakenly activated the object during an unauthorized experiment. The ensuing exposure to SCP-4455's effects resulted in widespread panic and chaos within Site-██.

Dr. ██████ became fixated on SCP-4455 and exhibited increasingly erratic behaviour. He single-handedly disabled security measures, neutralized on-site MTF teams, and released several other SCP objects from containment, all while evading capture.

The incident culminated in a catastrophic power outage, which further exacerbated the containment breach. Dr. ██████ was eventually apprehended, but not before causing the death of ██ personnel and the escape of ████ anomalies.

Addendum 2: Recovery Log 224554-01 SCP-4455 was discovered On ██/██/████ in an abandoned mansion located in [REDACTED], Germany, following reports of anomalous activity in the area. Foundation agents were dispatched to investigate, and SCP-4455 was recovered along with various notes and documents suggesting that the object had been intentionally hidden away.

Several of the recovered documents contained references to a "Grimace Cult," an ancient group believed to have worshipped SCP-4455 as a deity of fear and chaos. The documents hinted at rituals involving the object and its use to induce terror in their enemies.

The true origin of SCP-4455 and the Grimace Cult remains unknown, and research into the object's past and potential connections to other anomalous entities is ongoing.

Note: SCP-4455 poses a significant threat to both personnel and global security due to its capacity to induce widespread panic and cognitive impairment. Containment measures must be maintained with the utmost vigilance to prevent further breaches and the potential escalation of their effects.
