Basic Description:

SCP-CN-2753 is an incompletely self-sustaining device composed of pig iron; its exterior appearance is not fixed and lacks a defining pattern, not resembling any non-anomalous object. The object was contained at Site-191 on 1921/8/1, and was transferred to Site-CN-██ on 2000/1/1; during this period its effectiveness increased significantly, but slowed down on 2000/8/1.

The object's anomalous properties are particularly basic, and match the standard properties of most similar entities. As such, SCP-CN-2753 has been tentatively classified "Anomalous", to be updated with further analysis. Its properties can be split into the following three cases:

  • (1) The exterior appearance of the object will change in accordance with its structural changes. Based on its objective structure and composition, SCP-CN-2753 will use its internal gears and other metallic structures to visibly change its appearance. In most cases, SCP-CN-2753 will attempt to hide its internal components under its surface structure.
    • In extreme circumstances, that is, when its surface structure is unable to completely hide its internal workings, the internal components of the object can be seen to noticeably change and eventually become new surface structure.
  • (2) The internal components of the object are capable of self-replication, and some components are capable of technological iteration; based on property (1), every time the object is observed to change, its volume increases; in addition, it was observed that its singular damaged component had duplicated after one such incident. Some internal components display noticeable technological iteration after self-replication, such as "gears" in one generation giving rise to gears with different numbers of teeth.
    • The mechanism by which SCP-CN-2753 self-replicates is as yet unknown, as is the direct relation between the object's iteration and non-anomalous technological development; however, iterated components always follow the form of components in non-anomalous technology.
  • (3) All energy required for the object's operation is incompletely supplied by itself; however, SCP-CN-2753's core energy source is unknown. Of note is that when the object is directly observed by external personnel, its frequency of operation increases fourfold compared to when it is not observed. The number of personnel observing is likewise related to the the frequency of operation, and slowly approaches a fixed value, thought to be the "standard threshold".
    • Outside of direct observation, verbally discussing SCP-CN-2753 in a private space will also cause the same effect. The source of the object's sensory capabilities is as yet unknown.

The frequency of activity began to slowly decrease on 2000/8/01, accompanied by an increase in its standard threshold, and the rate of change of its structure slowly decreased over time. At one point, brown spots appeared on the object for a moment before being covered by the surface structure; with the exception of the object's surface constantly bulging and moving, there is no way to observe the interior of the object; as such, the recording of the object's technological iteration has been temporarily stopped.


SCP-CN-2753 disassembled after neutralization

On 2003/2/29, when the object was altering its exterior appearance, its surface structure began to move in reverse and the interior began to produce a piercingly loud scratching noise. Two seconds later, it continued functioning normally. The same phenomenon occurred on 7/23 that year, and continued to occur approximately twice a year. In 2015, this rate increased to thrice a month for an unknown reason. On 2016/1/20, brown spots were observed on the surface structure for the first time.

On 2021/7/12, SCP-CN-2753's surface had completely changed from its original silvery white to brown. On 8/1 the same year, SCP-CN-2753 appeared to jam while altering its external appearance, producing clear mechanical ramming and rolling noises in the following eight seconds before completely stopping operation; as of 2022/8/1, SCP-CN-2753 has not since activated, and it is thought that the object has been neutralized.

Upon disassembly, the object's interior was found to be completely rusted, and all components were completely incapable of operation. A shriveled human heart was found in the interior of the object, connected to the core motive mechanism for an unknown reason; autopsy revealed that a human subject with identical DNA to that found in the heart exists.

Just like you and me.
