Comparison of RPC-005 depictions throughout the years. Left to right: 1773, 1907.

Containment Protocols:

RPC-005 is currently at large in an unknown location; most likely to be in constant motion. The entity was last seen entering the waters along the coast of Faria Beach, California USA, following its containment breach on 03/12/1963.

RPC-005 is speculated to be roaming the surrounding areas of the city of Yogyakarta, Indonesia. Search parties assigned to the city should exercise utmost discretion, and to never mention the entity by name.

Recontainment personnel should utilize plasmatic accelerators to encourage quantum decoherence in RPC-005 and to prevent it from attaining entanglement. Do not attempt entity recontainment around bodies of water. Do not attempt lone recontainment.

In the case of a successful recontainment, RPC-005 is to be transported inside a standard Bell-State Disentanglement Chamber, and permanently kept in the specialized containment chamber located in Site-002-A. If possible, the entity should be sedated and maintained in an artificially induced comatose state prior to transportation.

In the case of an encounter by non-essential personnel: Maintain distance, discard any clothing articles in aqua green1 (if any), and immediately report the last known location of the entity to Colonel Johan McKiernan, or to the desk of MST Lima-09 "Edgerunners."


RPC-005 is a humanoid entity, appearing as an adolescent female human measuring 165 cm in height with a slim build and an approximate weight of 55 kg. Phylogenetics study suggests that RPC-005 descended from a southeastern Asian ancestor, specifically from the Indonesian island of Java.

Histology studies of its tissue samples suggest that RPC-005 does not age. This is evident in the telomeres2 at the end of its chromosomes not showing degradation typically exhibited in common human species. Furthermore, the length of its telomeres was considered to be far longer than that of any known human being on Earth, giving RPC-005 an increased resistance to genetic defects caused by chromosomal nondisjunction.3


Proton Density weighted MRI imaging of RPC-005's larynx.

EEG scanning of the brain indicates heightened activity on the cerebrum, which may correlate to the anomalous abilities exhibited by RPC-005. One such case was that RPC-005 was observed to exhibit the ability to manipulate its larynx to produce sounds in frequencies generally not possible for a human being to reliably produce without damage.

This is due to the thyroid cartilage of RPC-005 exhibiting an abnormal amount of chondrocytes,4 with the vestibular cord and the skeletal structure of its true vocal cords showing similar thickening of muscle mass. This, in theory, allows RPC-005 to produce specific sounds with minimal damage to its larynx.

Furthermore, in a tomography scan of RPC-005's skull, it was found that a small flap of soft tissue inside the ear canal can be moved at will by the entity that completely covers its eardrums. This means that the entity's hearing is completely immune to its own bouts of high-frequency screeches.

An example of the application of this increased pitch control is the ability of RPC-005 to produce a low-frequency sound that resonates with various substances. In this case, RPC-005 showed a preference to produce a continuous 19Hz sound that resonates perfectly with human eyes. This allows RPC-005 to disable an observer's visual acquisition of itself.

In another case, RPC-005 has been observed to generate a continuous 24Hz sine wave to manipulate the fluidic properties and dynamics of liquid matter. With precise pitch control, RPC-005 can extend this ability to deflect the movement of water and even imbibe a fluid source with non-Newtonian properties.5

One extreme case showed that RPC-005 possesses the ability to break down the covalent/ionic bonds between molecules, as shown in an experiment where RPC-005 separated a body of distilled water into its fundamental elements of hydrogen and oxygen gasses. However, the full scope of this ability is limited in both knowledge and documentation.

Temporary Descriptor [DEFERRED]

RPC-005 exhibited the ability to utilize its sound wave generation to manipulate electrical impulses in a subject's brain, effectively rendering them compliant to the entity's command. Research into this ability is currently underway.

However, researchers were not able to correlate its heightened brain activity with the control of its abilities. Some theories suggest that this was an indication of higher intelligence, which may be demonstrated by RPC-005's fluency and mastery of various languages.6 Research into determining the intelligence range of RPC-005 has proven to be troublesome, as the entity often refuses to cooperate, citing reasons that such activity was deemed "childlike."


During the height of the United States' anti-communist sentiments, the CIA was keen on overthrowing the Indonesian government for their alignment with the Soviet Union. In September 1957, the CIA set up bases in the Philippines and began funding rebels with weapons in the Sumatra and Sulawesi areas.

However, Soviet counterintelligence learned of the plan almost immediately and notified the Indonesian government accordingly. Soon after, the CIA received reports of a singular operative terminating said rebels and sabotaging vessels in the Phillippines base. This was later confirmed to be the act of RPC-005, working in tandem with the top generals of the Indonesian Army.9

On 21/02/1958, the Indonesian military managed to bomb CIA-funded rebel radio masts in Sumatera and established a naval blockade along the coast in the hopes of regaining intelligence advantage. However, the CIA soon learned that RPC-005 was seen to be among the elements of the naval blockade, which prompted them to throw in a last-ditch effort in eliminating the entity.


April 19th bombing.

On 19/04/1958, CIA attack aircraft began bombing various outlying islands which resulted in the deaths of both civilian and military lives. The CIA officially requested Authority assistance not too long after and on 24/04/1958, a joint effort between the CIA and the Authority was established, resulting in Operation Kingfisher.

As with the complete failure of the CIA in hiding their involvement in the coup effort, Authority commanders advised the CIA to conduct covert ops instead. Approximately 16 intelligence agents were embedded in various Sumatran settlements, with almost 70 natives acting as informants.

After about 20 days of intelligence gathering, the CIA learned that RPC-005 was stationed temporarily in the Hinako Islands, west of Nias. To prevent further knowledge of their involvement in Indonesia, the CIA agreed to relinquish all containment efforts to the Authority's hands.

On the night of 26/05/1958, elements of Authority's 3rd Pacific Fleet moved into the waters south of the Hinako Islands. The containment effort took 3 hours to complete and resulted in the deaths of 1357 Authority agents,10 the destruction of 1 cruiser, 3 destroyers, and the complete obliteration of Hamutala Island.

RPC-005 was then transported by air in an artificially induced comatose state to a temporary containment site on the outskirts of Site-002. The construction for Site-002-A began 4 months after the initial containment on 29/11/1958.
