SCP-003

**Item #:** SCP-003

**Object Class:** Euclid

**Special Containment Procedures:** SCP-003 is to be
maintained at a constant temperature of no less than 35°C and ideally
kept above 100°C. No living multicellular organisms of Category IV or
higher complexity may be allowed to come into contact with SCP-003.

In event of total power failure, if SCP-003-1 begins to increase its
mass, assigned personnel must engage in skin contact with SCP-003-1.
Ideally, personnel may use their body heat to return SCP-003-1 to above
the critical temperature; however, skin contact must be maintained even
in event of SCP-003 reaching activation temperature, lasting at minimum
until SCP-003-1 advances fully to its second growth stage.

Personnel who enter SCP-003's containment area must first be examined
 for body parasites of Category IV or higher complexity, and sterilized
if such organisms are present. All personnel who have come in physical
contact with SCP-003-1 are to immediately report for sterilization
afterwards.

SCP-003-1 must not be removed from SCP-003-2 except in case of
emergency procedures detailed above. Any significant change in
SCP-003-2's rune activity (including pattern, frequency, or color)
should be reported within three (3) hours of occurrence. Cessation of
rune activity must be reported immediately. SCP-003-2 must be supplied
with power via the source designated Generator 003-IX at all times.

**Description:** SCP-003 consists of two related components of separate origin, referred to as SCP-003-1 and SCP-003-2.

SCP-003-1 appears to be composed of chitin, hair, and nails of
unknown biology similar to SCP-████ and SCP-████, arranged in a
configuration similar to that of a computer motherboard. Testing reveals
 SCP-003-1 to predate earliest known circuit boards by a factor of
thousands of years. SCP-003-1 is considered sentient but not actively
dangerous except under certain conditions.

SCP-003-1 was found on a stone tablet, SCP-003-2, on which it
currently resides. The runes on SCP-003-2 are not part of any known
language, and emit pale, flickering light patterns.

SCP-003-2 is controlled by a (non-biological) internal computer, the
contents of which are mostly inaccessible without risk of damaging
SCP-003-2. SCP-003-2 is capable of controlled emissions of radiation,
including heat, light, and anomalous radiation types. SCP-003-2 contains
 an internal power source of an anomalous nature, which appears to have
been losing power since several centuries before discovery.

It is considered probable that SCP-003-2 was created for the purpose
of containing SCP-003-1. Partially interpreted data recovered from
SCP-003-2 may refer to a past and/or potential future LK-class
restructuring event caused by SCP-003-1.

SCP-003 was located by remote viewing team SRV-04 Beta. It appears
possible that SRV-04 Beta was deliberately contacted by SCP-003-2. Other
 organizations have also been alerted to SCP-003's existence, possibly
by similar means. Despite this activity, SCP-003-2 does not appear to be
 sentient, based on its lack of reaction to M03-Gloria analysis and
procedures.

When SCP-003 drops below the temperature of 35°C, both components react.

First, SCP-003-1 enters a growth state characterized by an
exponential increase in mass. This growth state consists of two stages.
In both stages, SCP-003-1 partially fuels its growth by converting
matter around it, starting with any surrounding inorganic material,
including atmospheric elements, then nonliving organic material,
including cells of dead skin, hair, chitin, enamel, keratin, and other
biological materials.

The first stage is always the same. SCP-003-1 will first increase its
 mass, then take a form similar in shape to an ophiuroid (brittle star)
of fifteen meters in diameter (including what appears to be a central
processor of three meters in diameter). It will form sensory organs that
 appear to scan its surrounding environment, and will partially convert
the area around it to an unidentified anomalous substance (SCP-003-2
seems immune from conversion).

The second stage describes a growth alteration which occurs when
SCP-003 comes into contact with living organic material; SCP-003 appears
 to "template" itself off of the organic material, and will attempt
communication with organisms that match its initial "template" or
"templates".

In its second stage, SCP-003-1 may pause, slow or change its growth,
and will also convert inorganic and nonliving organic elements into
functionally similar structures while anomalously altering their
physical makeup.

While growth is consistent in the first stage, in the second stage
SCP-003-1's growth rate is diminished by 20-90% so long as SCP-003-1
remains in contact with living organic material. The percentage is
determined by the complexity of the organism(s) in contact with
SCP-003-1; SCP-003-1 appears to devote a large amount of processing
power to analysis of living organic material.

During each of SCP-003-1's growth stages, SCP-003-2 releases bursts
of radiation that temporarily inhibit SCP-003-1's growth, or reverse
this growth when the temperature of SCP-003-1 rises above 100°C. Similar
 radiation emissions have been replicated or recorded via other
anomalous means.

**Addendum 003-01**: Acting on information gathered from
 linguistic analysis of SCP-003-2's runes and comparative data analysis,
 Research Team M03-Gloria has managed to establish a link between
SCP-003 and [DATA EXPUNGED] for analysis of functions. SCP-003-1 must
now be considered sentient, and is to be kept a minimum of 1 km from
[DATA EXPUNGED] and the resulting "by-product" at all times.

**Addendum 003-02**: SCP-003-2's power loss has been
exacerbated by the procedures performed by M03-Gloria. On orders of
O5-10, M03-Gloria will continue procedures.

**Addendum 003-03** During M03-Gloria procedures,
SCP-003-1 doubled its mass and began rapid structural growth.
Temperature was immediately returned to 100°C. Growth and mass increase
of SCP-003-1 continued for 9 minutes and 6 seconds, at which time a
sustained radiation spike was produced by SCP-003-2. In response,
SCP-003-1 returned to its normal state in 3 minutes and 39 seconds. New
growth dissolved into a dusty residue which was collected for analysis.
Both SCP-003-1 and SCP-003-2 ceased all detectable activity. SCP-003-2
did not resume activity until connected to external power source.
SCP-003-2's runes glowed uniformly gray and did not resume normal
activity for three (3) hours. SCP-003-2 no longer appears to be able to
maintain containment area at a temperature above 35°C without external
power supplied by Generators 003-III through IX.

**Addendum 003-04**: The procedure detailed in Addendum
003-03 was repeated, and SCP-003-1 again entered a growth state. After
10 minutes and 13 seconds, SCP-003-2 once again produced a sustained
radiation spike. SCP-003-1's growth stopped for 36 seconds, then resumed
 at its previous pace.

On quadrupling its mass, SCP-003-1 formed a coherent outer shell and
body. After appearing to scan its environment and partially converting
its environment, SCP-003-1 then breached containment, entering the
observation gallery where nine members of M03-Gloria were present. On
physical contact with team members, SCP-003-1 encompassed them in
rapidly-grown appendages and stopped growth for 15 minutes. SCP-003-1
then resumed growth, and rearranged the component parts of the center of
 its form to the shape of a three-meter-tall female humanoid, with
peripheral "tentacles" shifting to extrude primarily from SCP-003-1's
newly formed "hair" and spine. SCP-003-1 then produced rudimentary
vocalizations in an apparent initial attempt to communicate with
researchers. [DATA EXPUNGED]

An unknown individual approached the compromised containment area in
company of a full squad of agents. The individual claimed to be acting
on orders of O5-10 and attempted communication with SCP-003-1. [DATA
EXPUNGED]

Following this incident, Agent Jackson of M03-Gloria successfully
restored power to SCP-003-2 and activated backup generators to return
the temperature to 100°C. SCP-003-1 returned to its normal state in 21
minutes and 7 seconds, and was successfully re-contained without
incident.

All nine members of M03-Gloria affected by SCP-003-1 were afterwards
found to be physically unharmed, with no residual effects besides
psychological trauma. The converted materials of SCP-003's former
containment area did not dissolve and are now under analysis.

**Addendum 003-05**: In light of the previous incident,
O5-10 was removed from the O5 Council by joint decision of O5-██, O5-██,
 and O5-██. M03-Gloria procedures have been indefinitely suspended.
