Item #: SCP-XXXX

Object Class: Keter

Special Containment Procedures: Samples of SCP-XXXX are to be stored at biological research site-104. In case of a cross-species transmission of SCP-XXXX between a rodent and non-rodent species, SCP-XXXX is to be treated as a potential biohazard and is not to be handled without appropriate precautions. SCP-XXXX is to be closely studied in order to identify any potential mutations. Incineration measures are to be deployed in a breach of containment of SCP-XXXX.

SCP-XXXX-1 are to be contained in modified Small Fauna Containment chambers equipped with ventilation ducts and are to be fed an appropriate amount of food and water for their respective species daily. Only SCP-XXXX-1 instances of a single sex are to be contained with one another in order to prevent breeding. SCP-XXXX-1 are to be monitored under 24-hour surveillance.

For the purposes of experimentation, SCP-XXXX-1 instances are to be impregnated via invitro fertilization, and the gestation of SCP-XXXX-2 is to be closely monitored. When an instance of SCP-XXXX-1 gives birth, nitrous oxide is to be pumped through the ventilation ducts into the containment chamber, and all SCP-XXXX-2 instances are to be transferred from containment and deployed inside the testing zone. SCP-XXXX-2 are to be injected with nanite explosives that are to be triggered when testing is complete, or in the event of a containment breach.

Description: SCP-XXXX is a species of protozoa capable of infecting any rodent and altering their biological functions. Animals infected by SCP-XXXX (hereby referred to as SCP-XXXX-1) display numerous differences from non-anomalous counterparts. Young SCP-XXXX-1 instances will fully mature within the span of an hour. Mature SCP-XXXX-1 instances will attempt to produce offspring (hereby referred to as SCP-XXXX-2). SCP-XXXX-2 display similar patterns of aging to SCP-XXXX-1 when born.

The teeth of SCP-XXXX-2 are comprised of an unknown metallic substance that varies in its appearance. 72% of SCP-XXXX-2 instances observed possess teeth that are reddish brown, resembling iron oxide, 25% possess teeth that are blue, resembling scorched steel, and 3% possess bluish green teeth resembling verdigris. The tissue of SCP-XXXX-2 are interlaced with polyurethane and several compounds that have yet to be identified. Testing has revealed the tissue of SCP-XXXX-2 serves as an excellent electrical insulator, aiding SCP-XXXX-2 in their primary goal.

SCP-XXXX-2 will seek out certain kinds of infrastructure and attempt to destroy them using their teeth. The preference of infrastructure depends on the species of the SCP-XXXX-2 instance. For example, smaller instances such as mice, rats and squirrels will attempt to chew through drywall and sever electrical wiring, burrowing animals such as groundhogs and mole rats will attempt to destroy underground structures such as fiberoptic cables, plumbing, and subway wires, and larger instances such as beavers, porcupines and capybaras have been observed attempting to destroy telecommunications towers, power grids, railway tracks, bridges and, although rare, the drive shafts of vehicles. When the preferred type of infrastructure is not available, SCP-XXXX-2 will target the nearest available alternative.

SCP-XXXX-2 are non-hostile to humans unless an individual attacks a nearby instance of SCP-XXXX-1 or SCP-XXXX-2 or attempts to separate SCP-XXXX-2 from their target. SCP-XXXX-1 instances have not displayed any hostile behavior beyond that which is considered normal for their species. SCP-XXXX-2 display atrophy of sexual organs and have not been observed attempting to find a mate or breed. In addition, SCP-XXXX-2 do not require sleep or sustenance beyond oxygen.

SCP-XXXX was brought to the attention of the SCP Foundation in 19██, when reports of a colony of beavers attempting to destroy a transformer surfaced during a blackout in ██████████, USA. Instances of SCP-XXXX-2 involved were terminated, and cover story involving a geomagnetic storm was circulated by the Foundation following administration of Class A amnestics to all witnesses of SCP-XXXX-2.
