In one instance, SCP-2490's target locked it in a closet, then turned around to see SCP-2490 emerging from a nearby bathroom. SCP-2490 appears to have a type of short-range teleportation (although another hypothesis is that there are multiple instances of SCP-2490). Targets uniformly report SCP-2490 either moving towards them without moving its legs (with its arms outstretched) or scuttling in a matter akin to a crab. As a result of this behavior, targets usually express lack of sleep, extreme paranoia, introversion, and a phobia of mannequins. SCP-2490 will pursue the target for anywhere between several hours and several months, often showing itself to the target from a range before fleeing. Targets have often reported seeing normal persons transform into SCP-2490 before it begins pursuit. The target is (or will become) immune to the mechanism that SCP-2490 uses to disguise itself, but SCP-2490 makes no attempt to disguise its behavior if spotted. SCP-2490 displays behavior consistent with game stalkers, identifying a person (or multiple persons) and methodically stalking them, usually through urban and rural areas. Based on target testimony, however, most observers perceive it as an ordinary human being. SCP-2490 possesses claws that appear to be grafted to its hand pods. Its body consists of multiple white, jointed segments. SCP-2490's head is composed of a single, oblong beige capsule, on which two eyes have been painted and no other facial features are present. SCP-2490 refers to a modified human being, believed to be Chaos Insurgency Special Operative Alpha-19, that has stalked at least ██ Foundation employees since 19██. Employees attacked by SCP-2490 should be transferred to Site-44A (Foundation Center for Neurological Disease). If the object cannot be moved, then all security measures (codes, guard schedules, modular perimeter defenses) around it are to be modified immediately, with an emphasis on constant in-person surveillance. Any anomalous object that the compromised personnel worked with should be moved to secondary classified locations at the discretion of the Site Director. Personnel compromised by SCP-2490 are to be placed on indefinite paid leave and their security clearance is to be immediately revoked. Mobile Task Force Psi-7 ('Home Improvement') is currently tracking down anomalous objects believed to have been stolen by SCP-2490.

Mobile Task Force Alpha-5 ('Honor Guard') is to monitor any compromised personnel at all times, and incapacitate SCP-2490 if possible. Personnel are made to be aware of possible raids, terrorist action, and spies from the Insurgency, and are to notify their superiors about any activities from fellow personnel fitting the Insurgency behavioral profile.All Foundation personnel are to be informed of SCP-2490's properties, and are encouraged to inform their Site Director if they suspect pursuit by SCP-2490. The Foundation has also been infiltrated by agents of the Insurgency in the past, resulting in the loss of valuable scientific data, theft of a number of anomalies, and deaths of personnel. This organization is directly antagonistic to the Foundation, using deadly force to attempt to prevent Foundation containment of multiple anomalies. The main base of operations of the Insurgency is unknown, as are its current leaders. The SCP objects and other anomalies stolen from the Foundation typically possess high potential for direct utility, but the Insurgency has also made use of anomalies with less direct applications, such as SCP-884. Both of these objects were originally obtained at no small cost by the Foundation, and were stolen by the original founders of the Insurgency. Among the most notable items are the 'Staff of Hermes', an item capable of warping the physical and chemical properties of any matter it touches, and the 'Bell of Entropy', an object that can cause a variety of destructive effects depending on where it is struck. Most of the anomalous objects possessed by the Insurgency are unknown. It helps to maintain the extreme poverty and war that is suffered by these countries, so that it can continue its radical experimentation, easy conscription of forces, and lucrative business deals with various opposing factions. It makes use of authoritarian regimes in poor and developing countries, often using their populations in the same manner as the Foundation does D-Class personnel. The Insurgency not only deals in anomalies, but also in weapons running and intelligence gathering. Since then, the Insurgency has become a major player on the world stage, using the anomalies that it obtains for its own benefit and to consolidate its global power base. Overview: The Chaos Insurgency is a splinter group of the Foundation, created by a rogue cell that went A.W.O.L.
