Item #: SCP-5000
Object Class: Euclid
Special Containment Procedures: Its behavior towards an employee is determined by how they were treated by said employee in the past. SCP-5000 needs to be put in a room that's around 21 cm³.

Description: SCP-5000 is a sentient humanoid being, they have the ability to recognize human speech however they can't speak it their self. Every once in a while SCP-5000 will hit the wall of its containment chamber to let any employee nearby know that it either needs food, water, or to let then know that they are "bleeding". Their blood is a thick black substance, it is unknown as to what the substance is exactly. The substance is currently known to burn through any objects which are made up of plastic, wood, and paper, it however doesn't burn through skin.

Addendum 1:
To find out more about the "blood" of SCP-5000, We got a sample of the substance with the help of SCP-294 Here are some of the important logs from the testing

Log 1:

Date Recorded: [DATA EXPUNGED]
Today Agent ██████ spilled the cup of the thick black substance, and some of it got on his hands.
We were initially worried, Agent ██████ seemed perfectly fine.

End of Log

Log 2:

During the testing of The Black Substance, we discovered some more information about it
Here are the notes:
* anyone who is in possession of the substance will act calm, even if they normally aren't.
 * this includes some SCPs, but only if they are Class Safe or Class Euclid, if they are normally not calm this effect will only last 5 minutes. this explains SCP-5000's calm behavior.
* this substance can not be destroyed normally, however after a while, if not fully enclosed, after an hour it will evaporate.

Log 3 (Log 1 Update):

After all of the testing, Agent ██████, seemed to have forgotten what happened, here is an audio log of this:

Agent ██████: Hey Guys... When are we doing the testing?

Dr. [Redacted]: We already did the testing... remember?

Agent ██████: Oh... I don't remember it... how long ago did we do it?

Dr. [Redacted]: 15 minutes ago, and it ended 5 minutes ago.

Agent ██████: Do you know what might have caused me to forget?

Dr. [Redacted]: Maybe the Black Substance, before we began the test, you accidentally spilled it on your hands, it didn't affect your skin though.
