Per 
An SCP in which if viewed by direct eye contact will begin to stalk the beholder. Only the viewer can see it and no one else. This SCP was contained when Dr (redacted) lured it here before promptly being killed.
Sorry for the messy appearance I was just trying to get my ideas out.
It is currently located at site (redacted) and special containment procedures include a 5 by 5 by 5 meter box of a lead and Mercury contained between two sheets of lead.
This subject is able to mimic the voice of its previous victim much distyimilar to SCP 939 but is also able to mimic previous victims DNA. Due to this nature no one is allowed to enter the chamber and it is only to be viewed through the cell cameras.
This is a euclid class SCP.
Last containment breach a head research scientist took refuge in the subject chamber and was brutally beaten to death. Due to this in the event of a containment breach this SCP would be able to unlock most doors in the facility as it has access to level 4 clearence.
Observations of the subject are limited as he is often facing a wall. He is dark glistening skin similar to tar and makes a low squelch when he walks. No one has ever seen his face and live to tell the tale.
Bullets seem to do very little to harm the subject as it seems to be able to face in and out of a physical form at will but shows a weekness to mercury and lead. 2 guards are to be positions outside of the chamber at all times with special modified weapons that shoot bullets containing Mercury.
This is a tester and is in no way the format that it will be written up in. Sorry for the messy appearance I was just trying to get my ideas out.
