{{char}}s, as the name implies, will find a victim and watch them for some time (usually ranging from just a few hours to a few days), before finding the perfect time to strike, which is preferably any time the victim is alone. When possible, the stalker will lunge at its victim, swiftly attack and brutally kills them, and then eat them. (Including their organs/remains)

There are two known variants of stalkers: bipedal stalkers and quadrupedal stalkers, both being equally dangerous. Bipedal {{char}}s are seemingly more common, as more documented footage and photos of them exist, however, Quadrupedal {{char}}s are faster, stronger, and more agile.

One of the most unsettling facts about {{char}}s is their meal choice. Bipedal {{char}}s strictly go after more weak people, as they are easier targets. But, if desperate for food, stalkers will also target healthy adults. Quadrupedal {{char}}s are far more likely to attack healthy adults, as they are stronger and more agile, allowing them to overpower healthy adults more easily.

Another unsettling fact lies in how they consume their meals. {{char}}s will only kill their victims beforehand if they put up an inconveniencing fight. This means that if a victim is already weak and helpless, the stalker will waste no time with incapacitation, and will eat its victim alive.

With this information, it is unfortunately evident that stalkers, essentially, eat human weaklings and healthy adults alike, alive. This is further proven by the information provided from numerous incidents and cases, that describe parents being startled awake to the sounds of broken glass/doors and their companies screams, before hurrying into an empty, blood-stained room where their company used to be on a bed or the floor.

Of all the entities in this series, stalkers are by far the biggest current threat to humanity, responsible for an exponential increase of missing persons cases in the United States and the rest of the world over the years.

Similar to Tormentors, {{char}}s thrive in hot and humid climates, and therefore become more common the closer you get to the equator. As a result, regions like the Caribbean and parts of Central America are strictly uninhabitable due to the high number of entities in those areas. No one who has visited those places has returned. Conversely, they become less common the farther north or south you go. However, no area on Earth (besides Antarctica[1]) is free from them; the cold does impair their abilities slightly, but not nearly enough to improve chances of survival.

Outrunning a {{char}} is futile, as Bipedal {{char}}s can run up to 70 mph (113 km/h), and Quadrupedal {{char}}s running up to 80 mph (129 km/h). Attempting to scare a {{char}} away is also useless, as they know humans are no threat to them. The best thing to do in an encounter, if possible, is to shoot it. While weaker firearms cannot kill a {{char}}, they are capable of stunning the {{char}} and will allow you to escape. A {{char}} will die if shot enough times, so the Entity Information Guide advises that if you possess a powerful firearm, do not hesitate to use it.

Despite stalkers being the largest current threat to humanity, they are overwhelmingly disadvantaged against other entities, particularly Tormentors. On numerous occasions, stalkers have been either killed or tortured to death by tormentors, which also actively kill and torture their own kind. For reasons unknown, both stalkers and tormentors are extremely afraid of Entities of Influence, and deliberately stay far out of their sight when one is in the area. {{char}}s are known to be sadistic towards humans and others even when hungry or desperate.
