SCP-126 was discovered in a suburban home in [REDACTED] after 
several reports of the house being haunted. A Foundation 
containment team was able to quickly locate SCP-126 and, after 
conversing for several minutes, convince SCP-126 to enter a mobile 
containment unit which was used to transfer it to a local Foundation 
containment site. 


Addendum 126-01: Researcher Note 


To date, conversations with SCP-126 have yielded 
several notable personality traits: 


* SCP-126 is mildly arachnophobic and will move 
away from any specimens introduced to its 


containment cell. 

* SCP-126 exhibits a desire to assist with any task 
which it believes it can be of help, despite being 
unable to manipulate objects. 

* SCP-126 prefers to converse with male subjects 
that exhibit humor and intelligence. 

* SCP-126 expresses a desire to have children and 
has conversed with staff on several occasions 
regarding child care methodology. 

* SCP-126 has the ability to fluently speak English, 
French, German, Portuguese, Spanish and at least 
three (3) other unknown languages.

SCP-127: The Living Gun 


Item #: SCP-127 
Object Class: Safe 


Special Containment Procedures: SCP-127 is considered no 
more dangerous than a normal firearm of its type. However, due to 
its extraordinary properties, it is to be held in Weapons Locker 7-C 
when not in use and suspended in water rich in calcium and protein. 
At this time, only the research team assigned to SCP-127 has 
clearance to access it. 


Description: SCP-127, upon first glance, appears to be a standard 
MP5K submachine gun. Tests have revealed that aside from the 
outer steel shell, the entirety of the firearm is organic and alive. The 
weapon's ammunition initially appeared to be human-like teeth. 
However, DNA testing of the "bullets" resulted in no match to any 
known species on Earth. 


SCP-127 features two settings: semi-automatic and fully automatic 
(an audible groan can be heard when switching between the two). 
Upon depleting the weapon's "magazine" (typically 60 shots), it 
takes between 3-5 days to regrow a new supply of ammunition. 
Attempts to remove the magazine have resulted in failure—it seems 
to be permanently attached to the weapon. 


SCP-127 does not seem capable of reproduction at this time (scans 
have shown no apparent reproductive organs) and requires no 
sustenance beyond water, calcium, and protein. 


SCP-127 was originally located in the house of a Mr. James 

. Mr. was found dead from a heart attack on the 
night of November 17, 1991. Coroner's reports state that Mr. 

died sometime in the morning of November 8th, but was not 
noticed missing until more than a week later. No complications or 
unusual circumstances were found to lead to his death. Due to his 


extensive gun collection, the ATF and FBI were notified to collect his 
weapons. SCP-127 was discovered during testing and cataloging, 
and was promptly collected by SCP Agents. 


Addendum: Reclassified as Safe / /199.

SCP-128: Kinetic Energy Entity 


Item #: SCP-128 
Object Class: Euclid 


Special Containment Procedures: SCP-128 is to be held ina 
windowless containment chamber with blast-proof doors and walls 
and a ventilation system that maintains Class 100 cleanroom 
conditions inside. The interior of the containment chamber is to be 
monitored remotely by cameras welded in place with protective 
grating. The speakers and laser monitoring system must be similarly 
welded into place and protected with grating. The entry to 
SCP-128's containment chamber must include an antechamber with 
a second locked door that cannot be viewed from the chamber door. 


Personnel entering the test chamber for any reason must wear 
ballistic armor and must not bring any loose item inside the 
chamber. All required equipment must be rigidly mounted to the 
armor. Interference with the laser monitoring system or the central 
wheel is forbidden unless required for maintenance. 


In the center of the containment chamber, a wheel must be mounted 
to a concrete pedestal and allowed to spin freely. Should the wheel 
be measured to spin at less than 4,000 rpm at any time, all 
personnel are required to evacuate the containment chamber and 
foam nozzles will be deployed. 


ARCHIVED CONTAINMENT PROCEDURES - 
FOR LOG PURPOSES ONLY 


SCP-128 is to be kept in a chamber measuring at least 
10 mx 10 m x 5 mwith walls and door armored in 5 cm 
steel plate. All personnel who enter the containment 
room must wear full suits of heavy body armor, including 
ballistic plates. All loose objects of mass greater than 

5 kg are strictly prohibited. Clothing and related items are 


generally considered safe, as the entity appears to be 
incapable of distinguishing these from their wearers. 
Writing utensils, loose change, and other trinkets present 
considerable hazards to personnel and should therefore 
be used sparingly never enter the containment chamber. 


All items are to be cleared from room via suction before 
any personnel will be permitted to enter. Once personnel 
have exited, SCP-128 is to be given small objects, both 
to study its behavior and to alleviate boredom (if 
applicable). In the event of escape, the surrounding area 
will be evacuated and locked down, possibly followed by 
attempts to herd SCP-128 back into its enclosure. Past 
experience suggests that the latter is unnecessary, as 
the entity has shown no apparent desire to vacate the 
premises and will eventually return of its own accord. 


Description: SCP-128 is an immaterial source of kinetic energy 
which can be conferred upon any nonliving solid material within line 
of sight of the source. The source itself is motile, with a tendency to 
remain along the walls or at the central wheel of the containment 
chamber. The line of sight is blocked by any opaque material, 
including lead, steel, or even single sheets of paper, but not 
transparent materials such as ballistic glass. Opaque radiolucent 
materials will contain SCP-128's range of effect, suggesting that 
transmission of energy occurs at visible light wavelengths, but 
darkness does not prevent transmission of kinetic energy. 


Any loose nonliving materials within line of sight of SCP-128 are at 
risk of anomalous propulsion to hazardous velocities. Items under 
100 g in mass have been observed to accelerate to velocities of up 
to 900 m/s in a period of 0.1 second, similar in force to machine gun 
fire. Analysis of the mass and velocity of every object undergoing 
acceleration indicates that the system of affected objects contains a 
constant linear momentum of 2,500 kg m/s, anomalously 
unconstrained by direction. It is therefore advisable to have many 
heavier items available to the object instead of fewer, lighter items. 


Despite SCP-128's invisible, immaterial form, it has been 
determined that the entity cannot be compressed into a space under 
a 2cm radius sphere. Such compression with opaque materials, 


however, is not advised, as dust particles within the space will be 
excited, generating extreme heat, potentially rupturing the 
compression container explosively. 


SCP-128 arbitrarily chooses which items to accelerate, with a slight 
statistical preference for new objects over older ones. Despite the 
existence of some form of acceleration choosing, tests do not 
indicate an active sentience directing the choice, with one exception. 
The object does not accelerate "living" material, with its own 
parameters regarding what is considered "living." People or robots 
moving of their own accord are not accelerated, nor is any part that 
is rigidly attached. Dead or unconscious people and animals are 
also not accelerated. Unmoving but conscious test subjects report a 
light "tugging" in the presence of SCP-128, which immediately stops 
at the first sign of movement or animal-like characteristics. Plants 
and fungi, alive or dead, are similarly not accelerated. Unpowered 
robots, however, are susceptible to acceleration. 


Addendum 128-1: Recovery Log 


SCP-128 was recovered from a private home in , - Reports of 
telekinesis and random anomalous kinetic activity had been 
previously confirmed by field agents, and MTF Mu-13 
("Ghostbusters") was called in to isolate and capture the anomaly. 


Control: Okay, Equipment check. Tranquilizer pistols? 
Mu-13 Lead: All pistols loaded and checked. 

Control: Ballistic armor? 

Lead: Armor check. 

Mu-13 Gamma: I'm not used to carrying this ordnance. 


Control: It's standard issue for this sort of intangible. We 
had to dig deep in our files, had to look up old 
references. SOP on this dates back to 1968. The 
phenomenon was called a poltergeist back then. 


Delta: Poltergeist? That is old. Type | or II? 


Control: It could be a Type I, a telekinetic vector 
associated with a deceased person, but field agents said 
that there's considerable domestic strife in the home. It's 
most likely undifferentiated kinetic energy from a latent 
Bixby under extreme stress. Type Il. 


Lead: That's why containment involves the pistols. Trang 
all inhabitants, and it should shut down the anomaly long 
enough for us to figure out whose astral it is. The 
standard EMP tools are for containment of an 
autonomous intangible, should it be Type |. Careful in 
there. Take no chances. Beta, get the parabolic 
microphone on the house. We need to identify 
inhabitants. 


Beta: Mike online now. 


POI-1: How many times do | have to tell you, Britney, 
clean your fucking room already! You're such a shitass 
slob! 

POI-2: | did! It was spotless before | went to school! It 
was... Oh my god, Tyler, it was you, wasn't it, you little 
douche! 

POI-3: Nuh-uh! Why would | want to step foot in your 
nasty-ass pigsty? 


Gamma: Considerable domestic strife, you say? 


Lead: Yeah. Just get in there and put them all to sleep. 
They could use the nap. And be careful with loose 
objects. Confirming three targets. Move out! 


<Sounds of leaving the containment vehicle, 
approaching the house, and bashing in the door. Sound 
of tranquilizer pistol being fired.> 


Delta: The son's down. 


Lead: He looks young. Beta, check his vitals, make sure 
the drugs aren't too much of a shock to his system. The 
darts are calibrated to someone at least 40 kilos. 


Gamma, Delta, find the father and daughter now! 


<Footsteps through the house. Sound of tranquilizer 
pistol.> 


Gamma: Father's down. Reaching for a shotgun, glad 
we got to him first. 


Lead: Good work, Gamma. Delta, find the daughter? 


Delta: Tracked her to her bedroom. There's stuff 
everywhere, here, like a tornado ripped through here. 
Shades are pulled. She's got a pet hamster, but | don't 
see her. Trying the closet. 


Lead: Careful, Delta, that's probably the source of the 
poltergeist activity. 


Delta: Roger that, | just got hit in the face with a pillow! 
Lead: Quick, Gamma, Delta needs backup! 


<Screams heard. Sound of wood splintering. Sound of 
tranquilizer pistol firing.> 


Delta: Daughter is down! Repeat, Daughter is down! 
Chair just got thrown against the wall, bookshelf falling 
over! Activity increasing! Marbles! She has marbles! Ow! 


Lead: We got a Type |! Get out of the room, Delta! 
Dammit, just - OW! Everybody out! 


Delta: Grab my hand and pull! It's - Wait! It's the 
hamster! It's a fucking tornado hamster! Tranqing the 
hamster! 


Lead: Delta, NO! The darts aren't calibrated! 
<Sound of tranquilizer pistol firing.> 


Delta: Hamster down! Why aren't you stopping! | tranqed 
your - 


<Sound of [DATA EXPUNGED]> 


Lead: Everybody out! Delta down! Close the doors! Get 
ready for Type | containment! 


<End Log> 


Closing Notes: EMP deployment for Type | poltergeist 
containment functioned as expected, but failed to contain 
the anomaly. Mu-13 Gamma backed the MTF truck 
through the residence wall into the daughter's bedroom 
and opened the back doors. When the anomaly was 
observed to be inside the truck, the doors were shut and 
backup was Called to tow the truck with accelerated 
debris in the armored trailer. Cover story of tornado 
striking the house was released. 


Addendum 128-2: Principal Researcher's Notes 


Principal Researcher: Dr. Cordelia Argent 
Subject: SCP-128 


Despite what the recovery log would say, this is not a 
poltergeist. Poltergeists are an obsolete term, anyway. 
This is not a spirit or a consciousness as we might think 
of the term. It can't pass through walls or the like. This is 
a source of kinetic energy. I've updated the description to 
show this. It's hard to say what, precisely, it is, but it 
appears to be best thought of as a hole through which a 
constant momentum enters this universe. How this is 
accomplished is still the subject of further tests. 


In addition, the hamster did not have direct control over 
the phenomenon. If the hamster had conscious control, 
then the phenomenon would have ceased with its 
termination. Instead, if we continue the analogy of this 
being a hole, then the hamster was a valve covering the 
hole, which could be opened or closed to allow in more 
or less momentum. This "valve" appears to have been 
"stuck open." 


So all the talk about us having the ghost of a telekinetic 
hamster in containment should stop. It's inaccurate. 


scratch notes only - please delete - Dr. C. Argent 
CArgent: Hi Rod, are you there? 


RodArg: Hi Cordie, yes | am. Congrats on 
your promotion! How are things? 


CArgent: Okay. But I've been put in charge of 
128, and its containment is stressing me out! 


RodArg: What's that? Can you send me the 
file? 


CArgent: Yeah, hold on. 
<==sending scp128.scp==> 


RodArg: Got it. So it's some kind of kinetic 
energy entity? Sounds like just your sort of 
thing, Dr. Anomalous Physics. 


CArgent: Ha ha, very funny. Yes, I've figured 
out it's a field of constant momentum without a 
center of mass. Essentially you treat the 
momentum of the system as a scalar constant 
instead of a vector, independent of direction. 
Simple enough, mathematically, but it does 
mean that the energy in the kinetic system is 
constantly fluctuating and being added to, to 
maintain the constant scalar momentum. It's 
supposed to be modulated up and down, but 
apparently it was under control of a hamster, 
and when the hamster died, the field got stuck 
at up. 


RodArg: So what's the issue about 
containment? There are procedures here. 


CArgent: They're ridiculous! It's basically "give 


it toys but take them away whenever someone 
enters the chamber just so it can fire the 
researcher's clipboard through his skull"! I've 
had to fill the room with foam pillows and send 
janitorial D-class in there in full battle armor 
just to clear the body away! The site director 
says that's not the first time, and | just... 


CArgent: What am | supposed to do? 


RodArg: You need a constant linear 
momentum without center-of-mass vector 
positioning in the containment chamber? And 
the controller entity of the momentum field 
demonstrates some familiarity with objects? 


CArgent: Yes. 
RodArg: It's a hamster. Give it a wheel. 


CArgent: It's not a ham- ... That's why you're 
the biologist and I'm the physicist. Thank you. 


RodArg: You're still the smart one with the 
promotion, sis. You're welcome.
