Item #: SCP-4071
Object Class: Euclid
Special Containment Procedures: SCP-4071 is to be contained at Site-██ in a 20 ft x 20 ft x 20 ft cell made entirely of graphine and silicon carbide, two of the strongest substances known to exist. In case of a containment breach, the Heavy Containment Zone shall go on lockdown, and an MTF squad shall be assigned for recontainment. SCP-4071 shall be contained by doing the following: The assigned MTF squad shall stay fifteen (15) feet away from SCP-4071 until SCP-4071-2 emerges, and then play religious music to lure it to its chamber. In the case that SCP-4071 emerges while luring SCP-4071-2, the assigned MTF squad shall distance themselves fifteen (15) feet away once more until SCP-4071-2 re-emerges.
Description: SCP-4071 is a humanoid entity about five (5) feet eight (8) inches in height and one hundred fifty (150) pounds in weight. It has the same body shape of a typical fifteen (15) year old male, with the exception of its arm. Its arm is a ten (10) foot long whip that resembles a squid tentacle. Test subjects report it to be a ruthless, cruel person who seems to hate all forms of humanoid life. It seems to ignore animals when exposed to them.
SCP-4071 constantly makes attempts to breach containment. Its whip arm can destroy multiple layers of solid steel in one hit. Three attempts have been successful, but each time it was recontained within one (1) hour or less.
Test subjects have reported SCP-4071 to approach them the instant they enter the containment chamber. It has been observed that SCP-4071 tends to pursue its targets until: The target leaves its line of sight for sixty (60) seconds, or SCP-4071-2 emerges.
SCP-4071-2 is a humanoid entity about five and a half (5 1/2) inches tall that weighs one hundred (100) pounds. It has the same body shape of a thirteen 13 year old girl. Unlike SCP-4071, SCP-4071-2 does not hate most humanoid life forms, but it does not seem to follow people’s instructions. The one life form it despises is SCP-4071. It has a large insterest in its religion, and it enjoys religious music as well as religious books.
At any time, SCP-4071-2 can emerge from SCP-4071 and vice versa. When this happens, the starting entity’s features seem to melt into the emerging entity. This occurs over thirty seconds. During this period, screaming can be heard from both SCP-4071 and SCP-4071-2.
SCP-4071 and SCP-4071-2 have a hateful relationship with each other, and both have been reported to talk about ways to destroy each other.
Addendum: Test A - ████/7/13
Subject: D-████
Procedure: D-████ was placed in SCP-4071’s containment chamber. D-████ was asked to try to converse with SCP-4071 until SCP-4071-2 emerged.
Results: SCP-4071 immediately pursued the subject, ignoring any attempts to converse with the subject. About thirty (30) minutes later, SCP-4071-2 emerged, who then tried to make friends with the subject. Afterwards, Doctor █████ removed D-████ from the containment chamber.
Analysis: SCP-4071 will not wait to attack its target, no matter how the target tries to interact with it.
