Per 
My SCP idea
Throughout this text I will refer to my SCP as XXXX due to regulations
Item#: SCP-XXXX
Object Class: Euclid
Special Containment Procedures: SCP-XXXX must be kept in a standard size containment cell at Site-XX with no additional items inside. Only level 3 or higher personnel are allowed to enter, if any level 2 or under enter and interact with SCP-XXXX they must not be executed (See addendum XXXX for details). SCP-XXXX is allowed to walk around certain areas of the facility in the daytime and help personnel with daily activities.
Description: SCP-XXXX is a 6 ft tall human like creature made of a slime like substance with (5) colored "Eyes" that change with emotion. SCP-XXXX speaks in an unknown language consisting of gurgles and hums, entity has shown to socialize with any to all On-Site personnel. SCP-XXXX can "mold" itself into many shapes due to it's slime like body and does show to feel pain when doing so.
SCP-XXXX-2 is any personnel that have talked and become a "Friend" of SCP-XXXX, these persons are able to understand what SCP-XXXX is saying and sympathize for him. If any harm is done to SCP-XXXX-2, SCP-XXXX will enter a rage state (Red) and harm the inflictor with the same damage done to it's "Friend". No means of stopping this rage state have been found.
Whenever one of SCP-XXXX's "Friend"s are killed it will kill the inflictor and go into a saddened state (Blue) for 3 weeks before returning to normal. SCP-XXXX will enter a rage state if harmed (intentionally) by person and will carry out process of harm. If a "Friend" kills another "Friend" SCP-XXXX will immediately enter a saddened state and "Unfriend" person causing them to no longer be a case of SCP-XXXX-2.
SCP-XXXX was found in the bedroom of (Redacted)'s house next to the dead body of - - and - -. Subject was immediately taken into containment with no resistance, an interrogation was set but nobody could translate.
Addendum-XXXX (Audio file)
(D-XXXX enters SCP-XXXX's cell and stands at door for 4 minutes)
D-XXXX: (Clears throat) U-um, hello there.
(SCP-XXXX turns to look D-XXXX in the eye)
SCP-XXXX: (Incomprehensible gurgles)
D-XXXX: I-i don't think I understand what you're saying.
(SCP-XXXX sits quietly patting the floor next to it in a gesture to sit down)
D-XXXX: Um… ok (D-XXXX proceeds to sit next to SCP-XXXX)
(D-XXXX and SCP-XXXX sit quietly for 7 minutes)
D-XXXX: So why are you here?
SCP-XXXX: (Translated) I don't know, ask them (Points to security camera)
D-XXXX: Wait, did you just talk!?
SCP-XXXX: (Nods)
(They both site quietly again)
D-XXXX: (Shrugs) I don't know why i'm here either, first I was in a normal jail and now here.
SCP-XXXX: (Translated) Same except I was in a house with… (SCP-XXXX looks down, it's eyes turning blue)
D-XXXX: Hey, whats wrong buddy?
SCP-XXXX: (Translated) Just a rough past.
D-XXXX: Same here.
(They stay silent for a while then begin to have a conversation, the audio cut out halfway through so D-XXXX was retrieved and sent back to cell)
A few weeks later there was a breach in containment and due to regulations D-XXXX was executed, after this SCP-XXXX was shown breaching containment and killing the guard who shot D-XXXX.
SCP-XXXX is no longer allowed to interact with D-class personnel.
(Call me crazy, but we might be able to use this against other SCP's) Dr. --
