Item #: SCP-5219
Object Class: Keter
Special Containment Procedures: SCP-5219 is to be held in a room not smaller than 20m x 20m x 20 m in Site-███. SCP-5219’s cell is to be watched with security surveillance at all times. At least 5 Security Guards are to remain stand-by near to SCP-5219’s cell.
Description: SCP-5219 is a humanoid anomaly with height approximately 6 foot tall and weight of 50-70 kilograms and appears to be a muscular male. SCP-5219 wears a ripped cloth wrapped around his neck, predicted as a scarf of some sorts. Other than that, SCP-5219 wears a gray uniform, similar to Prisoner jumpsuits. SCP-5219 carries around a long sword made out of human bone. Hanging from his shoulder, there is a leather bag, presumably to store syringes that he uses to his subjects.
Attempts of harm done to SCP-5219 will result in small scratches that appear to do no damage whatsoever to SCP-5219. When a person is exposed to SCP-5219’s cell, SCP-5219 will begin to slash the subject’s neck with his bone sword, and will start to get closer to the subject to make sure the subject is not dead. Once done, it will then produce a syringe out of his bag and start to stick the nozzle into the dying subject’s bone, taking out the liquid inside the bone and putting it in his long sword.
Once SCP-5219 slashes his sword, no known material can stop the damage of the sword, but copper can withstand the bone sword the most.
Addendum [SCP-5219-A] : Discovery and background history
No background history is known from SCP-5219, except that he was found in ██████, Australia after a mass murder in which the victim shows no signs of having any skeletal feature and/or bone whatsoever.

[Begin Log]
Dr.C███: (*murmuring in the distance*)Is this thing on?
SCP-5219: (*In Australian accent*)Yes. I can quite hear you.
Dr.C███: Ah, good. Now let’s get straight to this. How about an introduction?
SCP-5219: How about you start?
Dr.C███: We do not tolerate that attitude in here. But uh, okay. I’ll start.
Dr.C███: I am Dr.C███, I am a Senior Researcher at The Foundation. Now you start.
SCP-5219: My name is ████████.
Dr.C███: (*Looking at his sword*)Is that sword of yours made out of bone?
SCP-5219: Exactly.
Dr.C███: I heard you used it to murder a bunch of people back in Australia.
SCP-5219: I… I… I freed them. I added them to this (*shows his sword*)
Dr.C███: NO YOU DID NOT. YOU JUST MURDERED BUNCH OF PEOPLE WHO HAD FAMILIES AND CHILDREN TO FEED.
SCP-5219: (*extremely agitated*) I… I clearly freed them… but it’s hard to deal with that logic… but the sword… it needs soul.
Dr.C███: What do you mean?
SCP-5219: I know you, from my young human days. The SCP Foundation.
SCP-5219: Is this steel? Or Iron?
Dr.C███: Huh? It’s steel.
SCP-5219: I can breach out of here easily.
Dr.C███: I consider that a threat. Security Personnel will escort you to your cell.
SCP-5219: (*In an angry sound*) I… am not a threat… I will pose no threat… I only free you… That’s my only goal… Free… Soul… Free… Soul… Free… Soul… Soul… Breach…
