Foundation Files: SCP-2599 is a 14-year-old female of Korean descent, formerly known as Zena Cho. SCP-2599’s anomalous effect has two components.

SCP-2599’s primary anomalous effect is a mental compulsion that causes it to be unable to disobey any direct commands. This effect is contingent on SCP-2599’s perception that it has received a command; should it not believe that it is receiving a command, it will not be compelled to follow it.

This effect currently has no known limits, and SCP-2599 has followed orders including self-harm, violence towards others, and other undesirable actions. SCP-2599 possesses a 0 on the Psychic Resistance Scale, currently the lowest recorded score on file.

SCP-2599’s secondary anomalous effect is its inability to fully carry out any given command. This effect causes SCP-2599 to fulfill most aspects of any command directed towards it, but it is unable to complete all requested components of the command, or does not complete the command satisfactorily.

Rigorous testing has concluded that this effect is involuntary, and is not motivated out of any desire for rebellion or dissatisfaction with commands that it has been given. SCP-2599 has been unable to complete commands even when it has wished to do so, due to its secondary effect. Once SCP-2599 is ordered to perform a certain action, it is no longer capable of successfully completing that action in the future, even if it was previously capable of doing so. This effect can be overridden with a successive command.

SCP-2599’s secondary effect allows SCP-2599 to perform other anomalous effects as well, though only under the direct wording of a command. The outcome of this testing is included in Document 2599-Alpha.

Document 2599-Alpha: The following is a testing log concerning SCP-2599. Personnel conducting tests with SCP-2599 should consult Dr. Wensley before appending this log. Use of SCP-894 by personnel and D-class has been approved to prevent unwanted activation of SCP-2599's effect. Testing of SCP-2599 with additional anomalies is approved on a case by case basis.
