Item #: SCP-5219
Object Class: Euclid
Special Containment Procedures: SCP-5219 Is to be held inside of a 5m x 5m x 5m concrete holding cell, 700 meters below sea level. It is to be kept inside of an airtight glass casing. If SCP-5219 were to be removed from containment for unsanctioned reasons, all windows are to be locked and blacked out. All lights in a 1km radius of last approximate location of the item are to be switched off, and all nearby personnel in that same 1km radius are to close their eyes. There is required to be 2 on-site janitorial positioned workers coupled with no less than 2 armed guards, suited with an AR-15.
If another subject unrelated to SCP-5219 were to exit containment, all possible entrances and exits regarding SCP-5219 or its containment are to be sealed airtight, and all responses to these protocols by SCP-5219 are to be ignored unless there are valuable site personnel inside of SCP-5219's containment.
In the situation regarding the birth of a new SCP-5219, all personnel in a 2m radius of the birth of SCP-5219-2 are to shoot the newborn subject as soon as it is visible. If any personnel hesitate, they are to be removed from SCP-5219's containment and shot on sight once outside of the cell.
Description: SCP-5219 resembles an unopened Pepsi soda can with 2 holes on parallel sides of the can, about an inch in diameter. If observed for long enough, two slender white arms, with one sharp claw on the end of each arm, will emerge from the holes.
SCP-5219 is a typically cognito-hazardous subject. If observed without proper gear, the observer will develop a headache, nausea, then fall into a coma within 3.2s of observation. Reports detail that an observer cannot lose the effects of SCP-5219's observation by looking away and looking back, as the effects will remain until the observer falls into a coma induced by SCP-5219. If left without observation for extended amounts of time, SCP-5219 will react erratically, sending large crystalized spikes, constructed of unknown material, towards all organic entities within a 1K radius.
Addendum: On the 32 recorded situations in which SCP-5219 escaped containment, only 2 included a situation in which SCP-5219 made a noise that was not created by the soda can "containing" SCP-5219. The first recorded noise was discovered in 1988, where the subject radiated a hypersonic screech, shattering all windows within a 2km radius, flooding the facility, and forcing the unauthorized relocation of SCP-5219.
4 on-site officers recall seeing 3 different forms of SCP-5219, however the 4 officers have since died due to undisclosed reasons.
