SCP-XXXX
Object Class: Keter
Plauge
Special Containment Procedures: SCP-XXXX is to be kept in a 10m×15m×19 meter cell, made of reinforced steel cell, with copper and silver plating covering the walls. SCP-XXXX is to be heavily restrained at all times, locked in a reinforced silver and copper cage with cuffs on its arms and legs at all times. If SCP-XXXX tries to break free, 10,000 volts of electricity is to be sent to the copper of the cage to restrain it. If it breaches cage, electric grid of cell should be turned on immediately, with as much power as possible. No personeal are to be within 5 meters of SCP-XXXX at any times, in fear of a SCP-XXXX-1 outbreak
Any individuals infected with SCP-XXXX-1 is to be terminated on sight before they can spread infection. The bodies are to be incinerated after termination, by D-Class personeal with level 4 hazmat suits.
Should SCP-XXXX breach containment, it is to be met with extreme force by all personeal. Electrical weaponry has proven most effective on SCP-XXXX, however, SCP-XXXX can still produce SCP-XXXX-1 even while incompasitated, so extreme caution is to be used. SCP-XXXX has proven to adapt to many forms of fatal damage, even electric, and termination is considered impossible.
Description: SCP-XXXX is a human male, 21 years of age. Subject has pale skin, black hair, with green-grey eyes. Subject is 1.93 meters tall, and weighs 72.575 kg. SCP-XXXX has not aged with the 30 years of being in containment, but still remains appearing as 21 years of age.
SCP-XXXX is, for the simplest term, insane. Subject suffers from many mental disorders, the most prominent being psychosis and schizophrenia. SCP-XXXX seems to communicate with 3 beings on multiple occasions, with no sign of other life around it. SCP-XXXX's psychosis shows in how all beings, human or not, to it are under "her" leadership. It is unknown who or what SCP-XXXX is referring to, nor if it is just a construct of its madness. No treatments to help normal patients with the disorders have worked for SCP-XXXX.
SCP-XXXX is very hostile, and will attempt to kill anything it comes across. SCP-XXXX has very high strength, able to break through a steel door with no struggle. SCP-XXXX prefers to kill in the most brutal way it can, most commonly in removal of spines or the head. SCP-XXXX will speak while attacking, however, the speech seems to be directed to the three figures sees, or the unknown female. SCP-XXXX has a very powerful regenerative property, that allows it to recover from any wound. SCP-XXXX will also adapt to the form of damage dealt, soon making it useless on it.
If the area around SCP-XXXX is filled with multiple targets, it will begin to produce SCP-XXXX-1. SCP-XXXX-1 is cells of SCP-XXXX that have turned into a virus. The virus can travel through the air, and infect individuals within thirty seconds of exposure. SCP-XXXX-1 causes the infected to become as mad as SCP-XXXX, although they do not speak of the entities SCP-XXXX does. The infected become hostile immediately, and will quickly begin to kill all that is around them. Those infected are able to produce SCP-XXXX-1 as well, although it is a weaker strain, requiring more exposure for success. There is no cure for SCP-XXXX-1, as the virus is still present on the deceased. Burning the bodies has proven effective in eliminating the virus. If all individuals have been killed, SCP-XXXX will then kill the infected before wandering aimlessly to the next living thing in its sight.
While very regenerative, SCP-XXXX is unable to adapt to electric damage, which has proven to be highly effective against it and individuals infected with SCP-XXXX-1. When SCP-XXXX is incapacitated, SCP-XXXX-1 may be produced as a defensive trait. Caution is advised at this point.
Addendum-1: SCP-XXXX once breached containment after a short circuit caused the fail safe to malfunction. During this time, it encountered SCP-058. SCP-XXXX seemed to have been stopped in its place, staring down SCP-058. Before mobile task force used Tesla weapons on SCP-XXXX, they heard it speak to SCP-058. The speech was quiet, but recordings have made out what it said:
You… are… like… me… made… a monster…
The meaning of this is unknown. SCP-XXXX has not shown any thoughtful speech since
Incident-XXXX-7: SCP-XXXX breached containment, and spread SCP-XXXX-1 throughout Site-19. Afterword, 45 infected escaped the facility, and headed to the closest populated area. Mobile Task Forces were sent immediately to intercept the infected, and succeeded in preventing the spread. SCP-XXXX was missing for 5 days, with no trace of its actions on the media. Subject was found in Siberia, 250 meters away from SSCP-1440. SCP-XXXX looked in its general direction for 20 minutes, ignoring all agents around it. SCP-XXXX then spoke once more:
We… made… monsters… my… fault…
SCP-XXXX willingly shocked itself and was returned to the foundation. Research in a connection of SCP-1440 and SCP-XXXX is undergoing.
