Item #: SCP-5133
Object Class: Keter
Special Containment Procedures: SCP-5025 is to be contained in a 6 m x 6 m x 6 m humanoid containment cell at all times. They shall be provided proper accommodations such as a bed, table, ect. and any requested accommodations approved by the Foundation. Personnel of level 3 clearance or higher are allowed to enter SCP-5133's containment with appointed guards. Personnel are not allowed to interact with SCP-5133 unless it is for testing purposes or given direct permission to by the Foundation.
There are no containment procedures for SCP-5133-2 as it seems to be able to materialize and dematerialize at the will of SCP-5133.
Description: SCP-5133 is a white male in their early thirty's, around 1.92 meters tall. They have blue eyes, dirty-blonde hair and a somewhat slim but fit build. They also have extensive military training and know most forms of martial arts and speak English along with another language that is currently unknown consisting mainly of hand gestures similar to sign language. They tend to suggest to others to refer to them as "Shadow".
From the initial tests, SCP-5133 did not seem to have anomalous properties, but upon further testing they showed a variety of abilities. Starting with the most prominent, SCP-5133 demonstrated the ability of advanced metamorphosis or "shape-shifting", being able to turn into a large variety of forms, the most common being a winged reptilian humanoid of various kinds each with unique abilities.
Along with the ability to transform into a wide variety of things they also showed to have abilities such as super-speed, super-strength, the ability to summon barriers made of pure energy that deflect all incoming projectiles and can absorb blasts from explosives, inhuman reflexes, and enhanced regenerative capabilities. Perhaps the most worrisome being their regenerative capabilities, this ability is similar if not faster than SCP-682's regeneration, recovering in a matter of seconds from more minors wounds such as stab wounds, cuts, lacerations, ect. while taking at least an hour or so to recover from gunshot wounds and explosive damage.
SCP-5133 is generally kind and cooperative with Foundation staff, often trying to make light conversation, making jokes, and has displayed incredible intellect. They can also be rather serious and cold often making remarks about their military experience. They have been observed on occasion to become rather hostile in the presence of certain staff members and most D-class personnel and has killed three D-class while making remarks about the crimes they have committed and about how they will be punished for their sins.
SCP-5133 has been observed on many occasions with what they often call a "skeletal dragon" which will be labeled as SCP-5133-2. Most of the time SCP-5133-2 is seen lying next to or nearby SCP-5133, and occasionally SCP-5133 will interact with SCP-5133-2 as if they were a common house pet. SCP-5133-2 has demonstrated sentience but is incapable of communication with anyone other than SCP-5133 itself. SCP-5133-2 seems to not need any form of food but occasionally eats, how the food is digested and processed is still unknown.
SCP-5133-2 seems to be defensive of SCP-5133 when in the presence of danger and will attack with its claws, teeth, and with a form of energy beam, capable of ripping through organic matter and causing major damage to armor, fired from the mouth. When questioned about SCP-5133-2 and what it is, SCP-5133 says that it is an extension of its own soul saying that's why it is capable of being sentient. They also made a remark on how "she" is generally friendly and won't attack as long as you don't give good reason to.
Addendum 5133-A-1: Initial interview after capture.
Interviewed: SCP-5133
Interviewer: Dr.██████
Foreword: SCP-5025 is currently in the form of what appears to be a winged reptilian humanoid with color-changing scales.
<Begin Log>
Dr.██████: (Flipping through notes)
SCP-5133: So shall I introduce myself or is that not gonna be necessary?
Dr.██████: Yes, that would be preferable.
SCP-5133: Ok, names Canaan but you can call me Shadow.
Dr.██████: And I am Dr.██████. Are you aware of where you are currently?
SCP-5133: Very, we are currently in one of the interview rooms of Site-19.
Dr.██████: (shocked silence)
SCP-5133: What you expected those tranquilizers to work? Sorry to break it to ya but they don't, was just playin along to make life easier.
Dr.██████: (clearing throat) Well then moving on, do you know how you got here?
SCP-5133: That… not really all I know was it was through the means of an inter-dimensional rift between universes. Now how that rift formed I have no clue!
Dr.██████: Interesting, one final question before the end of this interview would you mind telling us of your past?
SCP-5133: (grows silent)
Dr.██████: Please tell us, this is just for the sake of documentation.
SCP-5133: NO
Dr.██████: No? Why is that?
SCP-5133: My past is not something I am willing to discuss with people like you! (Scales shift to red most likely symbolizing anger)
Dr.██████: Then I think that's enough for today.
SCP-5133: Agreed.
<End Log>
Interviewer's Note: SCP-5133 or as it prefers to be called "Shadow" seems to be rather sensitive about discussing its past, making me feel as if either discussing it would bring back past trauma or would reveal other sensitive information. Other than that they seem rather compliant and possibly has knowledge of things that would be of great use to the foundation.
A side note, their form during the interview didn't seem to have any other anomalous properties but we must be wary of anything that may immerge suddenly.
Addendum 5133-A-2: Observation Log
After having been in containment for approximately a week, staff have noticed the appearance of a skeletal creature in SCP-5025's containment cell. SCP-5025 seemed to be interacting with it, petting its head and talking to it. About an hour after this discovery we sent a team in to retrieve this entity for study.
Upon entering the cell, the entity took immediate notice and seemed to become wary. Seconds after, SCP-5133 spoke saying that and quote "Doin this is a bad idea, she don't like strangers tryin to grab her and haul her off so you best stop or things might get real messy." The team did not respond and proceeded where SCP-5025 spoke again saying "Well I warned ya, don't get mad at me when she decides to attack ya'll."
Proceeding forward, the team closed on the entity where it soon got hostile when one of the soldiers tried to grab it and proceeded to bite their arm going clean through the armor while also clawing at his chest. It did not take long for the entity to kill the soldier, and after the entire team opened fire on it where it soon began attacking all of them, biting, clawing ad even firing what seemed to be an energy based beam from its mouth that ripped clean through the armor, vaporizing everything it touched except the cell itself. Soon the entire team was killed and the entity calmed down, where it then walked over to SCP-5133 and lied down next to it. From now on all attempts to capture what will be labelled as SCP-5133-2 are not to be permitted as it seems at the time this is not possible.
Addendum 5133-G: Interaction Observation with SCP-682
SCP-5133:(Enters containment)
SCP-682: (notices and stands up)
SCP-5133: Well if it isn't the legendary lizard himself, this ought to be real fun. (Containment door closes)
SCP-682: This shall be fun as I rip you to bits and devour you! (charges SCP-5133 who engages in combat)
*intense fighting can be heard throughout the facility for 15-20 minutes*
SCP-5133: (Proceeds to slam SCP-682 into the ground with a sword it produced from its back to its neck) Now now that wasn't a good way to greet someone new so how about we calm down and have a "Proper" introduction.
SCP-682: (growls) Why should I?
SCP-5133: Well for starters if you don't I'll cut your head clean from your body, and that wouldn't be fun for you would it?
SCP-682: (glares at SCP-5133 and quietly growls)
SCP-5133: Better (proceeds to sheath the sword and step back, letting SCP-682 up) Now then names Canaan but I prefer to be called Shadow.
*After about 5-10 minutes of undeterminable talking a team is sent in to recover SCP-5133 and return them to containment*
<End Log>
Observation notes: It seems SCP-5133 is capable of subduing SCP-682 in a fight, possible use of SCP-5025 for re-containment and possibly destruction of SCP-682 in the future shall be considered. SCP-5133 and 682 now seem to be somewhat acquainted and able to get along slightly.
