Multiple instances of RPC-430

Registered Phenomena Code: 430

Object Class: Gamma-Red

Hazard Types: Sapient Hazard, Organic Hazard, Grouped Hazard

Containment Protocols: Any discovered RPC-430 instances are to be acquired for study and promptly terminated. Should safe acquisition not be possible, termination on location is permitted. Outbreaks of RPC-430 are to be quarantined and the site of the incident subsequently sterilized. Should this not be possible, the site and surrounding area is to be acquired by the Authority and any unauthorized organisms attempting to enter or exit the area are to be terminated. This is to continue until sterilization becomes possible.

Description: RPC-430 is the designation given to a multitude of entities resembling sea cucumbers, though they show a number of differences. RPC-430 is actually a species of slug, possessing an internal "shell" protecting the instance's internal organs. RPC-430 is also a terrestrial organism, living its entire life cycle either on land or [REDACTED].

RPC-430's most unique property is its unique life cycle and feeding habits. Adult instances of RPC-430 are parasitic in nature, absorbing the blood of other organisms for sustenance. It does this by means of what is presumed to be the equivalent of a mouth, however, no means of feeding are apparent, as the structure lacks any structure capable of tearing or piercing even weak structures. Should RPC-430 come into contact with any vertebrate, it will extend its feeding structure and attach to the host, at which point it will begin extracting blood. RPC-430 will remain attached to the host until either the host expires from blood loss, RPC-430 is forcefully removed or RPC-430 begins its secondary stage.

Should a fertilized instance of RPC-430 come into contact with a warm-blooded organism, the instance will attach and after feeding for some time, begin to burrow into the host. Hosts have reported that this process does not cause pain. It is unknown how RPC-430 manages to accomplish this without any method of piercing or tearing. Upon reaching a sufficient depth within the subject, RPC-430 will begin expelling eggs, which may number in the thousands, into the organs of its host, after which RPC-430 will expire.

After a short period of time, RPC-430 eggs will hatch. In the larval stage, RPC-430 possesses a mouth structure, not unlike that of fly larvae. RPC-430 larvae begin to feed off the host organism, growing as they consume mass. Notably, the larvae will not consume the skin or any anatomical structure exposed to the surface. The larvae will compete for resources, with larger larvae consuming smaller larvae. This process lasts until either the host expires or all larvae reach their adult size, at which points they will enter the pupal stage, usually appearing as large translucent cysts within the host's body. Upon the completion of this stage, which lasts from 15 minutes to 3 hours, an adult RPC-430 instance will emerge from the pupal stage. This entire process last an average of 5 hours, after which RPC-430 instances will shift into one of two stages:

  1. Should a sufficient number of RPC-430 instances be present such that they fill the host subject's skin, the instances will begin to move collectively such as to animate the former host's skin. These subjects are from this point on referred to RPC-430-A. RPC-430-A appear capable of vocalization in the former's hosts voice, despite not possessing any structure to produce these vocalizations. RPC-430-A also appears to be able to access the memories of the former host and may attempt to impersonate them to convince unaffected humans to come close to it. Should another human get within a suitable range, an instance of RPC-430 will emerge and latch to the subject, beginning the cycle again. An interview log with an instance of RPC-430-A is documented under Document-430-A12.
  2. Should the number of RPC-430 instance present not be sufficient to fill the host subject's skin, RPC-430 will not exit the larval stage. Instead, the larvae will continue consuming the host's flesh, now including the skin, as well as one another until only one instance remains. This instance, from this point on referred to as RPC-430-B, will then enter the pupal stage, though at a significantly larger size. Upon emergence, RPC-430-B will retain its feeding appendages, in addition to sprouting 6 "legs" which resemble a mix between human arms and legs. RPC-430-B show highly aggressive behavior, however, will usually not kill warm-blooded prey items unless in need of sustenance. RPC-430-B will restrain their victims until an instance of RPC-430 or RPC-430-A arrives and infects the subjects.

Document-430-A12: The following is a transcript of an interview conducted with an RPC-430-A instance, designated RPC-430-A2, and Researcher L█████.

Interviewed: RPC-430-A2

Interviewer: Researcher R█████

<Begin Log>

Researcher R█████: Before we begin, you understand you will be referred to RPC-430-A2 for this interview, correct?

RPC-430-A2: For the love of God, just call me ███████. We were friends, ████, and now you treat me like some kind of monster? I am your friend!

Researcher R█████: (inhales sharply) Okay, cut the [EXPLETIVE REDACTED], A2. I know what you are. My friend is gone because of th-those things inside of you. Or rather, those things that are you. I'm not falling for this crap.

RPC-430-A2: Is this how you treat all your friends, ████? Treating me like I'm some kind of animal instead of trying to help me? I'm aware I have a problem but you could do better.

Researcher R█████ looks at the floor before regaining his composure

Researcher R█████: Alright. You're not going to talk, we're not going to talk. I think we're through here.

RPC-430-A2: You can't just walk away from me, ████. I'm not an animal. I'm not a monster. A monster doesn't know [REDACTED], ████. I do. I'm still me.

Researcher R█████ begins to shut the door

RPC-430-A2: I'm still me.
