Intruder

An **Intruder** is an anomaly type found in all five games and every map of the "I'm On Observation Duty" series. An anomaly is categorized as an Intruder if it is a living being that was not present at the start of the game.

## Appearance

Intruders are living humanoids. They vary in size, with some appearing the same size as babies and others towering over any human being. While some are convincingly human-like, others are noticeably not, some featuring odd limb placement, unusual body positions/movements and various other non-human features. A large number of Intruders are naked, and those that do wear clothes are often found dressed in suits. Intruders always have a solid physical form, which is what makes them differ from ghosts.

## Abilities

Intruders all vary greatly, both in appearance and abilities, but below is a list of notable abilities and some examples:

* **Teleportation -** Many Intruders appear suddenly within the monitored rooms, with no sign of how they got in. Others will visibly teleport while on camera, quickly moving between positions or using it to approach the camera.
* **Levitation -** Intruders will occasionally appear peeking into windows on the second floor of a building, suggesting they have some ability to levitate. Others are seen hovering slightly above the ground.
* **Abyss Usage -** While rare, some Intruders are seen appearing/disappearing using abyss openings
* **Environmental Distortion -** Some Intruders warp the environment around them, somehow drawing a presumably fixed camera towards their location. Distortions that are able to kill the player will sometimes reveal an Intruder at the very end, suggesting they are the cause of these distortions.
* **Body Distortion/Morphing -** Intruders may stretch or distort various parts of their body, often doing so in order to close the distance between them and the camera so they can attack the player.
* **Vibrating -** Some Intruders vibrate in a manner that would be impossible, or at the very least dangerous for a human being. They often do this prior to attacking
* **Mimicry of Human Speech -** Some Intruders will "speak", often repeating one word or sound over and over.
* **Sound Anomalies -** Intruders can be accompanied by unusual sounds, such as distorted music/humming or even normal music.
* **Superhuman Speed/Strength -** Anomalies have been seen clinging to ceilings and moving around very quickly, feats that would be difficult for a normal human to perform
* **Killing Via Camera Link -** Aggressive Anomalies can kill the player, seemingly via the camera (except in the third game). It's unclear how they manage this, though some will destroy the camera or even take it from it's fixed position, without disrupting the feed.
* **Awareness Of Anomaly Reports -** A few Intruders will visibly react when reported, turning towards the camera, attacking the camera or even greeting the player.
* **Resurrection/Undeath -** Mostly seen with Timothy, who appears as a corpse in the second game, yet returns as a "living" Intruder in the 4th, despite still having a deadly gunshot wound on his forehead and slamming his head into a wall. He can also be seen walking/floating towards the player in the 3rd game, and lacks any signs of being a Ghost. Other Intruders also have what appear to be fatal wounds, yet still move about and breathe.
