Special Containment Procedures: SCP-4820 is to be kept in a standard humanoid containment module at Site-17 Armed Bio-Containment Area-14.1 Up to 5 liters of blood may be withdrawn from SCP-4820 in any given 24-hour period. Withdrawal of larger amounts, or the harvesting of any of SCP-4820's organs, must be approved by at least one Level 4 Personnel.
SCP-4820 need not be supplied with food, and refuses any offered to it. SCP-4820 has requested access to cooking implements, various spices, and a selection of sauces. These requests have been granted on a probationary basis, and may be revoked as a disciplinary measure if the need arises. Consumption of food prepared by SCP-4820 is discouraged.
Description: SCP-4820 is an adult Filipino man, apparently 40-50 years of age. The object is able to rapidly regenerate damaged or destroyed tissue. These capabilities possess no known limit; SCP-4820 can even regrow appendages that have been completely severed2. Regeneration time increases with the severity of the injury in question and the extent of the damage; minor incisions heal almost instantaneously, but extracted internal organs take several hours to regenerate. SCP-4820 does not appear to feel pain, and often fails to notice when it is injured.
It is currently unknown how SCP-4820 fuels this rapid regeneration; it requires no more food or water than a standard human.

Outcome
Additional Notes

Test #1
Pain Response
A 21 gauge syringe was used to withdraw 10ml of blood from SCP-4820's right arm. Subject questioned whether this caused him any pain or discomfort.
SCP-4820 reported no pain, as expected.
Extracted blood did not exhibit regenerative properties or other anomalous qualities.

Test #2
Epidermal Regeneration
A 5 cm square was removed from SCP-4820's left forearm.
Injury healed in < 5 seconds.
Removed epidermal tissue did not exhibit regenerative properties or other anomalous qualities.

Test #3
Burn Regeneration
The end of a small copper rod was heated to 70 degrees Celsius and held to the epidermis of the subject (right forearm) until a first degree burn manifested.
Injury healed in < 5 seconds.

Test #4
Bone Realignment
Left index finger dislocated.
Bone realigned almost immediately.

In keeping with Ethics Committee Mandate #9173, further tests required Ethics Committee Approval. Researcher Lee Roy Carlson submitted proposals for eight additional tests, six of which were approved. Proposed tests and their results, or reasons for denial of testing, are reproduced below.

Test #5
Limb Regeneration
Left index finger severed at the first knuckle.
Finger regrew from the stump. Simpler tissues regenerated first; first skin, then bone, then connective tissue, then muscles, and finally nerves.
New digit did not initially possess a fingernail; one later grew at the normal speed for a human.

Test #6
Limb Reattachment
Left ring finger severed at the first knuckle. SCP-4820 was instructed to attempt to reattach the severed member.
SCP-4820 attempted to reattach the severed finger by holding it to the stump. Reattachment did not occur; new tissue had already begun developing, and would not reassimilate the severed finger.
Regenerated finger lacked a fingernail, as expected.

Test #7
Surgical Limb Reattachment
Left pinky finger severed, then sewn back on.
Finger did not reattach. New tissue developed behind the sewn-on digit, forcibly tearing the old digit from the stitches as it grew.
Regenerated finger lacked a fingernail, as expected.

Test #8
Blood Regeneration
Extraction of blood via a standard IV apparatus until early symptoms of low blood pressure or blood loss. The extracted blood is then to be reinserted.
SCP-4820 exhibited no symptoms of blood loss. Testing halted following the extraction of 100 liters of blood, which were not reinserted for obvious reasons.
Extensive testing, including transfusion into D-Class test subjects, has shown no residual anomalies in extracted blood. Long-term storage of large amounts of SCP-4820's blood in multiple on-Site blood banks has been approved, although transfusion of the blood to essential personnel is recommended only in case of emergencies.

Test #9
Organ Regeneration
Right kidney removed.
Subject regenerated a replacement kidney within 4 hours.
The removed kidney was successfully transplanted into D-11424, whose kidney was previously lost during exploration of SCP-3379. Extensive testing showed no residual anomalies in D-11424. Usage of SCP-4820 as an emergency organ donor has been approved.

Test #10
Receptivity to Organ Transplantation
Left kidney removed, then replaced with a compatible kidney from a D-Class test subject.
DENIED
Proposed test poses too great a risk of unanticipated response to organic foreign bodies.

Test #11
Response to Inorganic Foreign Bodies
Stainless steel nail, .5 cm in diameter, driven through palm of left hand.
Wound did not heal until the nail was removed.
SCP-4820 was distressed by this result.

Test #12
Response to Critical Injuries
Stainless steel spike, 1 cm in diameter, driven through the heart.
DENIED
Proposed test poses too great a risk of death, permanent brain damage, or other unnecessary suffering to SCP-4820.

Addendum 4820-2: Transcript of an interview between Researcher Carlson and SCP-4820, shortly after its initial containment.

<begin log>
Researcher Carlson: Good afternoon, SCP-4820.Researcher Carlson: Yes. It's just the protocol, nothing personal.Researcher Carlson: I'm afraid not.Researcher Carlson: It was certainly a hostile environment. But you still survived on it for almost twelve years. Care to explain how?Researcher Carlson: What changed?Researcher Carlson: So what did you do?Researcher Carlson: And that's when you developed your anomalous properties?Researcher Carlson: What did you do when you realized this?Researcher Carlson: Then what did you do?

Addendum 4820-3: List of materials recovered from ████████ with SCP-4820.

1 metal survival knife, rusted and dulled to the point of uselessness
2 knives carved from a human tibia
2 shirts and 2 pairs of pants, consisting of human skin sewn together with sinew and hair
1 needle, carved from an unidentified human bone
1 set of chess pieces; the "white" side is carved from various fingerbones, while the "black" side is carved from toes
A crude shelter constructed of human skin and a single large piece of driftwood
Approximately 4,000 human teeth, piled neatly outside a cave entrance.

Addendum 4820-4: Transcript of a second interview conducted with SCP-4820, the day following its recovery.

<begin log>
Researcher Carlson: Good morning, SCP-4820.Researcher Carlson: I'm here to ask you some questions about the time you spent on the island.Researcher Carlson: We've recovered the materials you, ah, made. How did you do that?Researcher Carlson: Right.Researcher Carlson: We didn't find a net on the island.Researcher Carlson: Why not?Researcher Carlson: There was an entity in the cave?Researcher Carlson: But you did leave a pile of teeth outside it.Researcher Carlson: But why did you decide to pile them outside the cave?

The island where SCP-4820 was stranded.

Addendum 4820-5: Exploration of island and cave.
The unnamed island has a land area of slightly less than one square kilometer at low tide, and only a few hundred square meters at high tide. It is not inhabited by any animals or edible plants. Its only notable terrain feature is an irregular cave entrance approximately 1 meter high and 1.5 meters wide, located near the highest point of the terrain and opening to the south. The entrance allows passage into an elliptical cave, roughly 2 meters wide at its widest point, 2.3 meters high at its highest, and 3 meters deep. Thorough inspection of the cave revealed no anomalous qualities, although personnel did report a “funny feeling”.
Addendum 4820-6: Portion of the third interview with SCP-4820, conducted 2 weeks after initial containment.

<begin log>
Researcher Carlson: Hello again, SCP-4820.Researcher Carlson: I can file a request for some if you like.Researcher Carlson: Yes, well, that's actually why I'm here. To discuss your refusal to accept rations.Researcher Carlson: Well, we expected that you'd be eager to, uh, inject some more variety into your diet.Researcher Carlson: But why do you still insist on consuming your, uh, self?<end log>

Footnotes
1. Relocated by request of ABCA-14 Director Thomas MacLean, due to its usefulness in medical research and treatment.
2. SCP-4820 claims that it once recovered from complete decapitation, although this has not been tested.
3. Testing has not identified any genetic abnormalities that would explain SCP-4820's loose teeth.
