SCP-XXXX – The Reptilian Parasite
Item #: SCP-XXXX
Object Class: Euclid
Special Containment Procedures:
SCP-XXXX-a is to be kept in a 5 m by 6 m by 3 m (16 ft by 20 ft by 10 ft) containment chamber at all times. Walls are to be constructed of 0.3 m (3 ft) of concrete. SCP-XXXX-b is to be kept in a 10 m (33 ft) diameter tank, with a depth of 10 m (33 ft). SCP-XXXX-b’s tank is to be made with 30 centimetres (12 inches) of reinforced glass and a 7.5 centimetre (3 inches) thick steel frame. SCP-XXXX-b's tank is to be filled with salt water and is to be well filtered and kept at a constant temperature of -34 C (-30 F). SCP-XXXX-c is to be kept in a similar tank to SCP-XXXX-b, only the tank is to be kept at a constant temperature of 18 C (64 F). All living SCP-XXXX-d subjects are to be kept in 5 m by 6 m by 2 m human containment cells. No less than one (1) guard is to be stationed outside of each cell during SCP-XXXX’s waking hours.
All instances of SCP-XXXX are to be fed appropriate meals for the lower organism and fed three (3) fawns each day, one at 6:00 am CTZ, one at 12:00 pm CTZ, and one at 6:00 pm CTZ. The human lower counterpart of SCP-XXXX is to be granted permission to a blindfold and sound cancelling headphones while SCP-XXXX feeds to avoid psychological damage and discomfort. Maintenance is to be conducted during the eight (8) hours that all instances of SCP-XXXX are asleep; between 8:00 pm CTZ and 4:00 am CTZ. All instances of SCP-XXXX are to be audio and visually recorded at all times. In case of an escape attempt, the current holding facility is to go into an immediate Category Delta lockdown. In the case of SCP-XXXX breaching containment and escaping the foundation, MTF Epsilon-9 (aka. Fire Eaters) must be deployed, all samples of SCP-XXXX outside of the foundation must be incinerated. Due to how the cells of SCP-XXXX react without a host, flamethrowers are to be used to permanently dispose of all traces of SCP-XXXX. To date, all instances of SCP-XXXX have collectively been responsible for the death of at least twenty-one (21) Class-D personnel and two (2) research staff at its current containment site of Site 66 Site 104 Area 12.
All equipment used to research samples of SCP-XXXX is to be sterilised. All personnel who have come into direct contact with samples of SCP-XXXX are to be contained and help for observation.
Description: SCP-XXXX is a parasitic organism which has, so far, never been found without a host. SCP-XXXX seems to only affect organisms of the Phylum Chordata. SCP-XXXX is classified as the top half of all the organisms that have been infected so far. Samples taken from SCP-XXXX become nothing but a ball of stem cells within hours of leaving the body it was originally part of, but are able to last for years in this state. This is theorized as to be how SCP-XXXX spreads itself.
Through x-rays, SCP-XXXX has been shown to have a crude, avian skull, excluding the alligator-like skull. SCP-XXXX has an attenuated body with an average width of 18 cm (7 inches). Its beak has a similar structure to that of an alligator, only thinner and toothless. SCP-XXXX has two (2) arms, both with a length of 1 m (3 ft). SCP-XXXX lacks eyes, ears, and a nose, and thus uses those of its host. SCP-XXXX has shown to have some level of sentience, using the peripherals of their host to react to their surroundings and, when infecting a human host. Its hands are around 8 centimetres (3 inches) in width, with fingers around 6 centimetres (2 inches) in length, all webbed and with three (3) joints in each finger instead of the human two (2). SCP-XXXX’s ‘body and head’ are lime green, with darker ‘seaweed’ green stripes, around 30 centimetres (12 inches) in length, and each is about 2.5 centimetres (1 inch) apart. When feeding, SCP-XXXX uses three (3) thin tongues to wrap around whatever it is able to reach with its tongues and unable to reach with its hands. On average, SCP-XXXX stands at a height of 1 m (3 ft) with a weight of 15 kg (33 lbs).
SCP-XXXX has yet to be found naturally alone. SCP-XXXX has been naturally found inhabiting three (3) different animals.
SCP-XXXX-a’s lower half is an organism that closely resembles a Giant golden-crowned flying fox. SCP-XXXX-a is capable of flight, but only to an average height of 1.8 m (6 ft) and for an average time of thirty (30) seconds. SCP-XXXX-a’s lower counterpart is around thirty centimetres (12 inches) in height, with a weight of 1 kg (2.2 lbs), and a wingspan of 1.7 m (5.6 ft).
SCP-XXXX-b’s lower half is a small Beluga whale, which was presumably a calf when ‘infection’ occurred. SCP-XXXX-b's lower counterpart is 1.5 m (5 ft) long and with a weight of 60 kg (132 lbs) including the top counterpart.
SCP-XXXX-c’s lower half is a Great White Shark, which is presumably at sexual maturity and male. SCP-XXXX-c has a length of 5 m (16 ft) and has a weight of 800 kg (1764 lbs).
SCP-XXXX-d-47’s lower half is a 43-year-old Caucasian male, Class-D Personnel; D-98464. SCP-XXXX-d-47 stands at a height of 1.9 m (6.2 ft), with a weight of 73 kg (161 lbs), excluding the height of SCP-XXXX. SCP-XXXX-d-47 is currently the 47th Human that has been ‘infected’ with SCP-XXXX. All 46 other subjects, bar SCP-XXXX-d-48 (See Addendum 2) have died, either due to SCP-XXXX causing too much damage to the subject or they have committed suicide whilst unsupervised, most commonly through pounding their head against the wall of their cell, or intentionally aggravating SCP-XXXX.
When flamethrowers, symptoms take around three (3) days to show. Symptoms include discolouring of the back, feelings of dizziness, increased appetite, increased tiredness, and an eventual growth beginning at the top of the Thoracic Vertebrae. Over a period of anywhere from five (5) to seven (7) weeks, the growth develops into a fully formed SCP-XXXX.
Once SCP-XXXX is fully formed, the lower counterpart will experience intense migraines, headaches and stomach aches over a period of two (2) days. Afterwards, the subject will begin to lose control over minor movements while the subject is distracted, or asleep. Sleepwalking begins to become more common in the subject, especially during the set sixteen (16) hours of the day when SCP-XXXX is awake. Over a period of four (4) weeks, this will progress and develop as SCP-XXXX presumably ‘gets used to the host’. Eventually, SCP-XXXX will be able to completely take physical control of the host for up to one (1) hour. Mental control is currently something that SCP-XXXX seems to be incapable of. SCP-XXXX doesn't enhance the durability of the subject in any way, shape, or form. Subjects have still shown the same speed and strength they had before they were infected. However, attributes such as reaction time depend on SCP-XXXX as opposed to the infected.
The general behaviour of organisms while infected with SCP-XXXX does not change, except when the organism is human. It is believed that SCP-XXXX prefers to infect animals, as humans have a more complex and more emotional than most other animals. SCP-XXXX appears to become more aggressive whilst infecting a human. This has most likely been the cause of many of the suicides among the SCP-XXXX-d subjects, as either the parasite SCP-XXXX attacks the Human itself of the human commits suicide from the constant screaming or attacks from SCP-XXXX.
Observation has shown that SCP-XXXX has set times for waking up (4:00 am) and falling asleep (8:00 pm). When SCP-XXXX falls asleep, so does the infected subject. However, when SCP-XXXX wakes, that does not necessarily mean that the infected subject does as well. In many cases, in the few moments that SCP-XXXX has the infected subject to itself, it will attempt to use the subject to break out of the cell. Fortunately, due to the subject being asleep, it is rarely successful. Subjects infected with SCP-XXXX are unable to fall asleep once awoken will SCP-XXXX is also awake, no matter how many hours the subject has been awake beforehand. SCP-XXXX is also able to negate the effects of anaesthesia through unknown means.
Attempts to interrupt the sleep schedule have proved successful but have undesired consequences. SCP-XXXX seems to react violently to even the slightest of pain, even when asleep. After dispelling the immediate threat, SCP-XXXX will fall back asleep and proceed to wake up again at 4:00 am, or earlier if it is again threatened. During its waking hours, if the previous night was interrupted, its aggression will appear increased. Attacks on the infected become more frequent and violent.
Due to its hypersensitivity to pain, and ability to negate the effects of anaesthesia, surgery or removal of SCP-XXXX has proved unsuccessful as of current methods.
Additional: SCP-XXXX-a was found in a southern forest in The Philippines on ██/██/18██.
SCP-XXXX-b was found ██ off the northern coast of Greenland on ██/██/19██.
SCP-XXXX-c was found ██ off the eastern coast of Dyer Island, South Africa on ██/██/19██.
SCP-XXXX-d-47 was created on ██/██/20██.

Addendum XXXX-01: Due to the many suicide attempts of SCP-XXXX-d, its cell has been padded, and a psychological evaluation is to be given once a month.
Addendum XXXX-02: Due to recent events, more specifically a recent containment breach due to SCP ███, SCP-XXXX-d-48 was accidentally created through samples of SCP-XXXX entering Researcher A████ Hatton, a female researcher who was assigned to studying SCP-XXXX.
The following dialogue comes from three different interviews with Researcher Hatton. The first (1st) being shortly after infection was noted by Hatton; shortly after patches of green skin were appearing on her back. The second is taken from the second (2nd) week of living with SCP-XXXX.
Interview 3220-I-0048.1
Interviewed: SCP-3220-d-48, Researcher Hatton
Interviewer: Researcher Field
Foreword: The following interview was conducted on ██/██/20██, the first (1st) of the two (2).
<Begin Log>
Field: How are feeling today d-48?
SCP-3220-d-48: Please, do you have to refer to me as that?
Field: It’s just for the interview Hatton.
[An audible sigh is heard from d-48.]
SCP-3220-d-48: Fine. Well, if you must know, I feel like hell. I feel like if I stand up my legs will break and the floor will swallow me whole. I feel like I'm gonna pass out at any second. I feel like I gotta eat constantly, and I gotta sleep constantly, or everything is just gonna shut down.
Field: I see. Do you feel anything unusual?
SCP-3220-d-48: What?
Field: Some subjects, but not all of them, have commented on feeling crawling sensations along there back.
SCP-3220-d-48: No I, I can’t say I’ve felt anything like that.
Field: Okay, anything been hurting recently?
SCP-3220-d-48: Ha, you ask that like you already know the answer.
Field: We just want to make sure everything lines up with what we’re expecting to happen.
SCP-3220-d-48: Well like hell it wouldn’t be! If what you’re referring to is the fact that my back should be killing me then yes, you should feel really relieved to know that my back is indeed killing me!
Field: Hatton please, calm down.
SCP-3220-d-48: Calm down? Why should I calm down? Everything I’ve done up until now is now going right down the drain, and I’m joining these, things, in this strange, unique and undiscriminating hell!
[4 Second pause.]
SCP-3220-d-48: I’m sorry. I just needed to vent that out.
Field: It’s quite alright. I understand.
SCP-3220-d-48: You don’t but, that’s okay. Thanks.

Interview 3220-I-0048.2
Interviewed: SCP-3220-d-48, Researcher Hatton
Interviewer: Researcher Field
Foreword: The following dialogue was taken from the second interview between Researcher Field and Researcher Hatton on ██/██/20██.
<Begin Log>
Field: Good morning, d-48. How are feeling?
[An audible screech from the SCP-3220-d-48’s upper counterpart is heard.]
SCP-3220-d-48: Take a wild guess!
Field: Hatton, please. I understand that you’re probably in a sizable amount of pain.
SCP-3220-d-48: You definitely do not understand C██████! There is no way in hell you could understand the ‘sizable amount of pain’ I’m feeling!
Field: Look, we’re doing everything we can to fix this, alright?
[Another audible screech is heard from the SCP-3220-d-48 upper counterpart.]
SCP-3220-d-48: Well you better hurry up before either I kill myself, or this thing does it for me!
[A sigh is heard from Researcher Field.]
Field: “We’re doing our best Hatton. I promise.”
