Special Containment Procedures:

SCP-5217 is to be kept within a standard containment unit at Site-57 and is to be accessible only to personnel with level 2 clearance or above. All instances of SCP-5217-1 through -3 are to be contained within a hermetically sealed container and are only to be opened during testing or use in Project REPLENISH. Additionally, the testing of art, photography, and sculpture in any form upon SCP-5217 is restricted unless required for Project REPLENISH. Any personnel found in possession of any of the aforementioned materials when entering SCP-5217’s containment cell without proper clearance are to be detained, reprimanded, and demoted accordingly.


SCP-5217 is a copying machine, resembling a standard Dell Xerox Color Copier, with an abnormally large scanning tray, with a rectangular opening in place of the paper dispenser, and a symbol of a stylized M where the company logo would typically be. The machine’s anomaly manifests when a piece of organic matter, fossil, or an image of a perceived organism is scanned. Upon doing so the machine’s menu will ask if the operator would like to “add” “alter” or “continue”. If "continue" is selected, the machine will begin to lightly shake before dispensing a tray with three, translucent, embryonic sacks composed of a currently unknown, highly fragile, bio-degradable plastic hereby referred to as SCP-5217-1, -2, and -3.

When “add“ is selected, the menu will inform the operator to place another item on the scanner. Once this is done the menu will ask again if the operator would like to "add", "alter", or "continue". This menu will always reappear until “continue” is selected. Once "continue" is selected, and after all additional items are scanned, the machine will shake gently and SCP-5217-1 through -3 will be dispensed. However, SCP-5217-1 will now contain a genetically stable blend of all scanned items. SCP-5217-2 and -3's embryos will follow a similar form of splicing, but with each of the scanned organism's food sources and predators/ competitors respectively.

If “alter” is selected at any time, the touchscreen will display a map of the scanned organisms' genetic code and will allow an operator to alter the scanned organism(s) genes in whatever way they see fit. However, changes to the code that might cause the immediate death of the organism upon birth are locked.

SCP-5217-1 through -3 is the aforementioned sacks each containing embryos pertaining to the item scanned, with a perfect one to one ratio of males to females (when applicable) and symbols resembling that of the stylized M found on the machine etched into their internal structures1, but with the following differences:

  • 5217-1 contains the embryos of the average number of offspring said scanned organism would produce.
  • 5217-2 contains the embryos of species of plants, animals, or materials the scanned organism would subsist upon, as well as their respective food sources.
  • 5217-3 contains the species that would prey upon or otherwise compete with SCP-5217-1.

It should be noted that if any instance of SCP-5217-1 through -3 be broken, the embryos inside will rapidly mature until they reach adulthood. All site personnel are thus encouraged to exercise caution while handling 5217-1 through -3 instances.


SCP-5217 was discovered at the University of Tasmania, on April 6th, 2019, when numerous reports of sightings of the long-extinct Thylacinus cynocephalus (Tasmanian Tiger), began to circulate. An investigation was launched and it was discovered that Dr. Hugh Sanderson, head paleontologist at the university, was behind the Thylacinid's reappearance via the use of SCP-5217. Upon the capture and subsequent interrogation of Dr. Sanderson, it was revealed that the doctor had acquired the item while shopping for a replacement copying machine online from an anonymous seller on Craigslist and discovered the machine's anomalous prosperities when he tried to copy an image of a Labrador Retriever puppy for his office. Dr. Sanderson was later administered Class-A amnestics and released back into the general populace, while an investigation into the identity of the seller was launched (see Addendum-2).

On July 12th, 2022, agents investigating Dr. Sanderson's personal computer reported having found no evidence of the doctor's claims of being sold SCP-5217 over Craigslist. Furthermore, it was discovered that the doctor had not even used the website for over five years. A local MTF was dispatched to apprehend the doctor but upon the team's arrival at his home in Tasmania, Australia, the doctor was found to have died via cardiac arrest. Dr. Sanderson's corpse was recovered from his living room surrounded by tools and printer parts. A note was also discovered, inscribed with several lethal cognitohazards, which was clutched within the doctor's hand, the contents of which are transcribed below:

Most valued Production Unit H-SAN-43,

We here at the community would like to thank you for your contribution to the production of Ecological-Printers. As you know, these machines have proven to be invaluable to furthering our cause and your dedication to their development has not gone unnoticed.

However, it has also come to our attention that you have recently come under the watch of another organization, one whose attention could prove detrimental to our efforts. Not only that, but we have also learned that one of your printers has since been confiscated by the said organization as well. This is unacceptable, we know you understand the dangers the printers posses when being handled without the proper materials more than twenty times. An organization with such little training in the use of these printers, like the one that captured you, could lead to any number of catastrophic ecological disasters the community simply cannot handle if we are to achieve our goal. It is with these incredible failures in mind that we, the community, have unfortunately decided to let you go9.

We once again thank you for your many years of service and pray that your transition is not a painful one.


An autopsy was later performed upon Dr. Sanderson's remains where it was discovered that multiple symbols were etched into the doctor's internal organs, all in the shape of a stylized M.
